In the News

As March 14 approaches, it’s time to get ready to celebrate Pi Day! It’s the annual holiday that pays tribute to the mathematical constant pi – the number that results from dividing any circle's circumference by its diameter.

Pi Day comes around only once a year, giving us a reason to chow down on our favorite sweet and savory pies while we appreciate the mathematical marvel that helps NASA explore Earth, the solar system, and beyond. There’s no better way to observe this day than by getting students exploring space right along with NASA by doing the math in our Pi Day Challenge. Keep reading to find out how students – and you – can put their math mettle to the test and solve real problems faced by NASA scientists and engineers as they explore the cosmos!

How It Works

Dividing any circle’s circumference by its diameter gives us pi, which is often rounded to 3.14. However, pi is an irrational number, meaning its decimal representation goes on forever and never repeats. Pi has been calculated to 50 trillion digits, but NASA uses far fewer for space exploration.

Some people may think that a circle has no points. In fact, a circle does have points, and knowing what pi is and how to use it is far from pointless. Pi is used for calculating the area and circumference of circular objects and the volume of shapes like spheres and cylinders. So it's useful for everyone from farmers storing crops in silos to manufacturers of water storage tanks to people who want to find the best value when ordering a pizza. At NASA, we use pi to find the best place to touch down on Mars, study the health of Earth's coral reefs, measure the size of a ring of planetary debris light years away, and lots more.

In the United States, one format to write March 14 is 3.14, which is why we celebrate on that date. In 2009, the U.S. House of Representatives passed a resolution officially designating March 14 as Pi Day and encouraging teachers and students to celebrate the day with activities that teach students about pi. And you're in luck, because that's precisely what the NASA Pi Day Challenge is all about.

The Science Behind the 2021 NASA Pi Day Challenge

This year, the NASA Pi Day Challenge offers up four brain-ticklers that will require students to use pi to collect samples from an asteroid, fly a helicopter on Mars for the first time, find efficient ways to talk with distant spacecraft, and study the forces behind Earth's beautiful auroras. Learn more about the science and engineering behind the problems below or click the link below to jump right into the challenge. Be sure to check back on March 15 for the answers to this year’s challenge.

Sample Science

NASA’s OSIRIS-REx mission has flown to an asteroid and collected a sample of surface material to bring back to Earth. (It will arrive back at Earth in 2023.) The mission is designed to help scientists understand how planets form and add to what we know about near-Earth asteroids, like the one visited by OSIRIS-REx, asteroid Bennu. Launched in 2016, OSIRIS-REx began orbiting Bennu in 2018 and successfully performed its maneuver to retrieve a sample on October 20, 2020. In the Sample Science problem, students use pi to determine how much of the spacecraft's sample-collection device needs to make contact with the surface of Bennu to meet mission requirements for success.

Whirling Wonder

Joining the Perseverance rover on Mars is the first helicopter designed to fly on another planet. Named Ingenuity, the helicopter is a technology demonstration, meaning it's a test to see if a similar device could be used for a future Mars mission. To achieve the first powered flight on another planet, Ingenuity must spin its blades at a rapid rate to generate lift in Mars’ thin atmosphere. In Twirly Whirly, students use pi to compare the spin rate of Ingenuity’s blades to those of a typical helicopter on Earth.

Signal Solution

NASA uses radio signals to communicate with spacecraft across the solar system and in interstellar space. As more and more data flows between Earth and these distant spacecraft, NASA needs new technologies to improve how quickly data can be received. One such technology in development is Deep Space Optical Communications, which will use near-infrared light instead of radio waves to transmit data. Near-infrared light, with its higher frequency than radio waves, allows for more data to be transmitted per second. In Signal Solution, students can compare the efficiency of optical communication with radio communication, using pi to crunch the numbers.

Force Field

Earth’s magnetic field extends from within the planet to space, and it serves as a protective shield, blocking charged particles from the Sun. Known as the solar wind, these charged particles of helium and hydrogen race from the Sun at hundreds of miles per second. When they reach Earth, they would bombard our planet and orbiting satellites were it not for the magnetic field. Instead, they are deflected, though some particles become trapped by the field and are directed toward the poles, where they interact with the atmosphere, creating auroras. Knowing how Earth’s magnetic field shifts and how particles interact with the field can help keep satellites in safe orbits. In Force Field, students use pi to calculate how much force a hydrogen atom would experience at different points along Earth’s magnetic field.

Teach It

Pi Day is a fun and engaging way to get students thinking like NASA scientists and engineers. By solving the NASA Pi Day Challenge problems below, reading about other ways NASA uses pi, and doing the related activities, students can see first hand how math is an important part of STEM.

On Feb. 18, NASA's Perseverance Mars rover touched down on the Red Planet after a seven-month flight from Earth. Only the fifth rover to land on the planet, Perseverance represents a giant leap forward in our scientific and technological capabilities for exploring Mars and the possibility that life may have once existed on the Red Planet.

Here, you will:

Why It's Important

You might be wondering, "Isn't there already a rover on Mars?” The answer is yes! The Curiosity rover landed on Mars in 2012 and has spent its time on the Red Planet making fascinating discoveries about the planet's geology and environment – setting the stage for Perseverance. So, why send another rover to Mars? The lessons we’ve learned from Curiosity coupled with advancements in technology over the last decade are allowing us to take the next big steps in our exploration of Mars, including looking for signs of ancient microbial life, collecting rock samples to bring to Earth one day, and setting the stage for a potential future human mission to the Red Planet.

More specifically, the Perseverance Mars rover has four science objectives:

  • Identify past environments on Mars that could have supported microbial life
  • Seek signs of ancient microbial life within the rocks and soil using a new suite of scientific instruments
  • Collect rock samples of interest to be stored on the surface for possible return by future missions
  • Pave the way for human exploration beyond the Moon

With these science objectives in mind, let's take a look at how the mission is designed to achieve these goals – from its science-rich landing site, Jezero Crater, to its suite of onboard tools and technology.

How It Works

Follow the Water

Lighter colors represent higher elevation in this image of Jezero Crater on Mars, the landing site for the Perseverance rover. The black oval indicates the area in which the rover will touch down, also called a landing ellipse. Image Credit: NASA JPL/Caltech/MSSS/JHU-APL/ESA | › Full image and caption

While present-day Mars is a cold, barren planet, science suggests that it was once very similar to Earth. The presence of clay, dried rivers and lakes, and minerals that formed in the presence of water provide extensive evidence that Mars once had flowing water at its surface. As a result, a mission looking for signs of ancient life, also known as biosignatures, should naturally follow that water. That’s because water represents the essential ingredient for life as we know it on Earth, and it can host a wide variety of organisms.

This is what makes Perseverance's landing site in Jezero Crater such a compelling location for scientific exploration. The crater was originally formed by an ancient meteorite impact about 3.8 billion years ago, and it sits within an even larger, older impact basin. The crater also appears to have once been home to an ancient lake fed by a river that formed the delta where Perseverance will begin its exploration, by exploring the foot of the river delta.

Tools of the Trade

Perseverance will begin its scientific exploration with the assistance of an array of tools, also known as science instruments.

An illustration of the rover is shown with each of its science instruments deployed and identified.

This artist's concept shows the various science tools, or instruments, onboard the rover. Image credit: NASA/JPL-Caltech | › Learn more about the rover's science instruments

Like its predecessor, Perseverance will have a number of cameras – 23, in fact! – serving as the eyes of the rover for scientists and engineers back on Earth. Nine of these cameras are dedicated to mobility, or tracking the rover's movements; six will capture images and videos as the rover travels through the Martian atmosphere down to the surface, a process known as entry, descent, and landing; and seven are part of the science instrumentation.

The SuperCam instrument is shown on a laboratory table before being installed on the rover.

Navcam, located on the mast (or "head") of the rover, will capture images to help engineers control the rover. Meanwhile, Mastcam-Z, also on the rover’s mast, can zoom in, focus, and take 3D color pictures and video at high speed to allow detailed examination of distant objects. A third camera, Supercam, fires a small laser burst to excite compounds on the surface and determine their composition using spectroscopy. Supercam is also equipped with a microphone. This microphone (one of two on the rover) will allow scientists to hear the pop the laser makes upon hitting its target, which may give scientists additional information about the hardness of the rock.

Leaning more toward chemistry, the Planetary Instrument for X-Ray Lithochemistry (PIXL) will allow us to look at the composition of rocks and soil down to the size of a grain of salt. Elements respond to different types of light, such as X-rays, in predictable ways. So by shining an X-ray on Martian rocks and soil, we can identify elements that may be part of a biosignature.

Meanwhile, a device called SHERLOC will look for evidence of ancient life using a technique called Deep UV Raman spectroscopy. Raman spectroscopy can help scientists see the crystallinity and molecular structure of rocks and soil. For example, some molecules and crystals luminesce, or emit light, when exposed to ultraviolet – similar to how a blacklight might be used to illuminate evidence in a crime scene. Scientists have a good understanding of how chemicals considered key to life on Earth react to things like ultraviolet light. So, SHERLOC could help us identify those same chemicals on Mars. In other words, it can contribute to identifying those biosignatures we keep talking about.

Rounding out its role as a roving geologist on wheels, Perseverance also has instruments for studying beneath the surface of Mars. An instrument called the Radar Imager of Mars Subsurface Experiment (RIMFAX) will use ground-penetrating radar to analyze depths down to about 100 feet (30 meters) below the surface. Mounted on the rear of the rover, RIMFAX will help us understand geological features that can't be seen by the other cameras and instruments.

The rover's suite of instruments demonstrates how multiple scientific disciplines – chemistry, physics, biology, geology, and engineering – work in concert to further our understanding of Mars and help scientists uncover whether life ever existed on the Red Planet.

Next Generation Tech

At NASA, scientists and engineers are always looking to push the envelope and, while missions such as Perseverance are ambitious in themselves, they also provide an opportunity for NASA to test new technology that could be used for future missions. Two excellent examples of such technology joining Perseverance on Mars are MOXIE and the first ever Mars helicopter, Ingenuity.

MOXIE stands for the Mars Oxygen In-Situ Resource Utilization Experiment. Operating at 800 degrees Celsius, MOXIE takes in carbon dioxide (CO2) from the thin Martian atmosphere and splits those molecules into pure oxygen using what is called a catalyst. A catalyst is a chemical that allows for reactions to take place under conditions they normally wouldn’t. MOXIE provides an incredible opportunity for NASA to create something usable out of the limited resources available on Mars. Over the duration of the rover's mission, MOXIE will run for a total of one hour every time it operates, distributed over the course of the prime mission timeframe, to determine whether it can reliably produce breathable oxygen. The goal of operating this way is to allow scientists to determine the performance across a variety of environmental conditions that a dedicated, human-mission-sized oxygen plant would see during operations - day versus night, winter versus summer, etc. Oxygen is of great interest for future missions not just because of its necessity for future human life support on Mars, but also because it can be used as a rocket propellant, perhaps allowing for future small-scale sample return missions to Earth.

The Mars Ingenuity helicopter is likewise an engineering first. It is a technology demonstration to test powered flight on Mars. Because the Martian atmosphere is so thin, flight is incredibly difficult. So, the four-pound (1.8-kilogram), solar powered helicopter is specially designed with two, four-foot (1.2-meter) long counter-rotating blades that spin at 2,400 rotations per minute. In the months after Perseverance lands, Ingenuity will drop from the belly of the rover. If all goes well, it will attempt test flights of increasing difficulty, covering incrementally greater heights and distances for about 30 days. In the future, engineers hope flying robots can allow for a greater view of the surrounding terrain for robotic and human missions alike.

    Collage of intern photos that appear in this article

    Most years, summertime at NASA's Jet Propulsion Laboratory arrives with an influx of more than 800 interns, raring to play a hands-on role in exploring Earth and space with robotic spacecraft.

    Perhaps as exciting as adding NASA to their resumes and working alongside the scientists and engineers they have long admired is the chance to explore the laboratory's smorgasbord of science labs, spacecraft assembly facilities, space simulators, the historic mission control center and a place called the Mars Yard, where engineers test drive Mars rovers.

    But this year, as the summer internship season approached with most of JPL's more than 6,000 employees still on mandatory telework, the laboratory – and the students who were offered internships at the Southern California center – had a decision to make.

    "We asked the students and the mentors [the employees bringing them in] whether their projects could still be achieved remotely and provide the educational component we consider to be so crucial to these experiences," said Adrian Ponce, deputy section manager of JPL's Education Office, which runs the laboratory's STEM internship programs.

    The answer was a resounding yes, which meant the laboratory had just a matter of weeks to create virtual alternatives for every aspect of the internship experience, from accessing specialized software for studying Earth and planetary science to testing and fine-tuning the movements of spacecraft in development and preparing others for launch to attending enrichment activities like science talks and team building events.

    “We were able to transition almost all of the interns to aspects of their projects that are telework-compatible. Others agreed to a future start date,” said Ponce, adding that just 2% of the students offered internships declined to proceed or had their projects canceled.

    Now, JPL's 600-plus summer interns – some who were part-way through internships when the stay-at-home orders went into effect, others who are returning and many who are first-timers – are getting an extended lesson in the against-the-odds attitude on which the laboratory prides itself.

    We wanted to hear about their experiences as JPL's first class of remote interns. What are their routines and home offices like in cities across the country? How have their teams adapted to building spacecraft and doing science remotely? Read a collection of their responses below to learn how JPL interns are finding ways to persevere, whether it's using their engineering skills to fashion homemade desks, getting accustomed to testing spacecraft from 2,000 miles away or working alongside siblings, kids, and pets.

    "I am working with an astronomer on the NEOWISE project, which is an automated system that detects near-Earth objects, such as asteroids. The goal of my project is to identify any objects missed by the automated system and use modeling to learn more about their characteristics. My average day consists of writing scripts in Python to manipulate the NEOWISE data and visually vet that the objects in the images are asteroids and not noise or stars.

    My office setup consists of a table with scattered books, papers, and pencils, a laptop, television, a child in the background asking a million questions while I work, and a bird on my shoulder that watches me at times."

    "I'm helping support the Perseverance Mars rover launch this summer. So far, I have been working remotely, but I'm lucky enough to have the opportunity to go to Pasadena, California, in late July to support the launch from JPL! On launch day, I will be in the testbed, where myself and a few other members of my group will be 'shadowing' the spacecraft. This means that when operators send their commands to the actual spacecraft, when it’s on the launch pad and during its first day or so in space, we'll send the same instructions to the test-bed version. This way, if anything goes wrong, we'll have a high-fidelity simulation ready for debugging.

    I have a desk in my bedroom, so my office setup is decent enough. I bought a little whiteboard to write myself notes. As for my average working day, it really depends on what I'm doing. Some days, I'm writing procedures or code, so it's a text editor, a hundred internet tabs, and a messenger to ask my team members questions. Other days, I'm supporting a shift in the test bed, so I'm on a web call with a few other people talking about the test we're doing. Luckily, a large portion of my team's work can be done on our personal computers. The biggest change has been adding the ability to operate the test bed remotely. I'm often amazed that from New York, I can control hardware in California.

    I was ecstatic that I was still able to help with the Perseverance Mars rover mission! I spent the second half of 2019 working on launch and cruise testing for the mission, so I'm happy to be able to see it through."

    "I am working on the Perseverance Mars rover mission [launching this summer]. As a member of the mobility team, I am testing the rover's auto-navigation behaviors. If given a specific location, flight software should be able to return data about where that location is relative to the rover. My project is to create test cases and develop procedures to verify the data returned by the flight software when this feature is used.

    My average day starts with me eating breakfast with my mom who is also working from home. Then, I write a brief plan for my day. Next, I meet with my mentor to discuss any problems and/or updates. I spend the rest of my day at my portable workstation working on code to test the rover's behaviors and analyzing the data from the tests. I have a mini desk that I either set up in my bedroom in front of my Georgia Tech Buzz painting or in the dining room.

    If I could visit in person, the first thing I would want to see is the Mars rover engineering model "Scarecrow." I would love to visit the Mars Yard [a simulated Mars environment at JPL] and watch Scarecrow run through different tests. It would be so cool to see a physical representation of the things that I've been working on."

Our goal is to assemble and test the Psyche spacecraft to make sure everything works correctly so that the spacecraft will be able to orbit and study its target, a metal asteroid also called Psyche. Scientists theorize that the asteroid is actually the metal core of what was once another planet. By studying it, we hope to learn more about the formation of Earth.

    I always start out my virtual work day by giving my dog a hug, grabbing a cup of coffee and heading up to my family's guest bedroom, which has turned into my office for the summer. On the window sill in my office are a number of space-themed Lego sets including the 'Women of NASA' set, which helps me get into the space-exploration mood! Once I have fueled up on coffee, my brain is ready for launch, and I log in to the JPL virtual network to start writing plans for testing Psyche's propulsion systems. While the ATLO team is working remotely, we are focused on writing test plans and procedures so that they can be ready as soon as the Psyche spacecraft is in the lab for testing. We have a continuous stream of video calls set up throughout the week to meet virtually with the teams helping to build the spacecraft."

    "NASA's Deep Space Network is a system of antennas positioned around the world – in Australia, Spain, and Goldstone, California – that's used to communicate with spacecraft. My internship is working on a risk assessment of the hydraulic system for the 70-meter antenna at the Goldstone facility. The hydraulic system is what allows the antenna and dish surrounding it to move so it can accurately track spacecraft in flight. The ultimate goal of the work is to make sure the antenna's hydraulic systems meet NASA standards.

    My average day starts by getting ready for work (morning routine), accessing my work computer through a virtual interface and talking with my mentor on [our collaboration tool]. Then, I dive into work, researching hydraulic schematics, JPL technical drawings of the antenna, and NASA standards, and adding to a huge spreadsheet that I use to track every component of the antenna's hydraulic system. Currently, I'm tracking every flexible hydraulic fluid hose on the system and figuring out what dangers a failure of the hose could have on personnel and the mission."

    I was very excited when I got the offer to do a virtual internship at JPL. My internship was originally supposed to be with the Perseverance Mars rover mission, but it required too much in-person work, so I was moved to the Europa Clipper project. While I had been looking forward to working on a project that was going to be launching so soon, Jupiter's moon Europa has always captured my imagination because of the ocean under its surface. It was an added bonus to know I had an internship secured for the summer."

The ultimate goal is to make it easier for mission designers to use these low-energy trajectories to develop mission plans that use very little fuel.

    I'm not a gamer, but I just got a new gaming laptop because it has a nice graphics processing unit, or GPU. During my internship at JPL last summer, we used several GPUs and a supercomputer to make our trajectory computations 10,000 times faster!

    "I'm doing a theory-based project on the topic of nanotechnology under the mentorship of Mohammad Ashtijou and Eric Perez.

    I vividly remember being infatuated with NASA as a youth, so much so that my parents ordered me a pamphlet from Space Center Houston with posters and stickers explaining all of the cool things happening across NASA. I will never forget when I was able to visit Space Center Houston on spring break in 2009. It was by far the most amazing thing I have ever witnessed as a youth. When I was offered the internship at JPL, I was excited, challenged, and motivated. There is a great deal of respect that comes with being an NASA intern, and I look forward to furthering my experiences.

    But the challenges are prevalent, too. Unfortunately, the internship is completely virtual and there are limitations to my experience. It is hard working at home with the multiple personalities in my family. I love them, but have you attempted to conduct research with a surround system of romantic comedies playing in the living room, war video games blasting grenades, and the sweet voice of your grandmother asking for help getting pans from the top shelf?"

    "This summer, I am supporting the proposal for a small satellite mission concept called Cupid’s Arrow. Cupid’s Arrow would be a small probe designed to fly through Venus’ atmosphere and collect samples. The ultimate goal of the project is to understand the “origin story” of Venus' atmosphere and how, despite their comparable sizes, Earth and Venus evolved so differently geologically, with the former being the habitable, friendly planet that we call home and the latter being the hottest planet in our solar system with a mainly carbon dioxide atmosphere.

    While ordinary JPL meetings include discussions of space probes, rockets, and visiting other planets, my working day rarely involves leaving my desk. Because all of my work can be done on my computer, I have a pretty simple office setup: a desk, my computer, and a wall full of posters of Earth and the Solar System. An average day is usually a combination of data analysis, reading and learning about Venus, and a number of web meetings. The team has several different time zones represented, so a morning meeting in Pacific time accommodates all of Pacific, Eastern and European time zones that exist within the working hours of the team."

    “I'm characterizing the genetic signatures of heat-resistant bacteria. The goal is to improve the techniques we use to sterilize spacecraft to prevent them from contaminating other worlds or bringing contaminants back to Earth. Specifically, I'm working to refine the amount of time spacecraft need to spend getting blasted by dry heat as a sanitation method.

    "As someone who has a biology-lab heavy internship, I was quite skeptical of how an online internship would work. There was originally supposed to be lab work, but I think the project took an interesting turn into research and computational biology. It has been a really cool intersection to explore, and I have gained a deeper understanding of the math and analysis involved in addition to the biology concepts."

    "I am working on the engineering operations team for the Perseverance Mars rover. After the rover lands on Mars, it will send daily status updates. Every day, an engineer at JPL will need to make sure that the status update looks healthy so that the rover can continue its mission. I am writing code to make that process a lot faster for the engineers.

    When I was offered the internship back in November, I thought I would be working on hardware for the rover. Once the COVID-19 crisis began ramping up and I saw many of my friends' internships get cancelled or shortened, I was worried that the same would happen to me. One day, I got a call letting me know that my previous internship wouldn't be possible but that there was an opportunity to work on a different team. I was so grateful to have the opportunity to retain my internship at JPL and get the chance to work with my mentor, Farah Alibay, who was once a JPL intern herself."

It's also serving as a technology demonstration to advance future coronagraphs [which are instruments designed to observe objects close to bright stars].

    I was both nervous and excited to have a virtual internship. I’m a returning intern, continuing my work on the coronagraph instrument. I absolutely love my work and my project at JPL, so I was really looking forward to another internship. Since I’m working with the same group, I was relieved that I already knew my team, but nervous about how I would connect with my team, ask questions, and meet other 'JPLers.' But I think my team is just as effective working virtually as we were when working 'on lab.' My mentor and I have even figured out how to test hardware virtually by video calling the engineer in the lab and connecting remotely into the lab computer."

    "I am working on the flight system for the Perseverance Mars rover. The first half of my internship was spent learning the rules of the road for the entire flight system. My first task was updating command-line Python scripts, which help unpack the data that is received from the rover. After that, I moved on to testing a part of the flight software that manages which mechanisms and instruments the spacecraft can use at a certain time. I have been so grateful to contribute to the Perseverance Mars rover project, especially during the summer that it launches!

    I have always been one to be happy with all the opportunities I am granted, but I do have to say it was hard to come to the realization that I would not be able to step foot on the JPL campus. However, I was truly grateful to receive this opportunity, and I have been so delighted to see the JPL spirit translate to the online video chats and communication channels. It's definitely the amazing people who make JPL into the place that everybody admires. Most important, I would like to thank my mentor, Jessica Samuels, for taking the time to meet with me every day and show me the true compassion and inspiration of the engineers at JPL."

    I was ecstatic to still have my internship! I'm very blessed to be able to do all my work remotely. It has sometimes proven to be a challenge when I find myself more than four layers deep in virtual environments. And it can be confusing to program hardware on the West Coast with software that I wrote all the way over here on the East Coast.

    "My summer research project is focused on using machine-learning algorithms to make predictions about the density of electrons in Earth’s ionosphere [a region of the planet's upper atmosphere]. Our work seeks to allow scientists to forecast this electron density, as it has important impacts on things such as GPS positioning and aircraft navigation.

    Despite the strangeness of working remotely, I have learned a ton about the research process and what it is like to be part of a real research team. Working alongside my mentors to adapt to the unique challenges of working remotely has also been educational. In research, and in life, there will always be new and unforeseen problems and challenges. This extreme circumstance is valuable in that it teaches us interns the importance of creative problem solving, adaptability, and making the most out of the situation we are given."

    "I have two projects at JPL. My first project focuses on the Europa Clipper mission [designed to make flybys of Jupiter's moon Europa]. I study how the complex topography on the icy moon influences the temperature of the surface. This work is crucial to detect 'hot spots,' which are areas the mission (and future missions) aim to study because they might correspond to regions that could support life! My other work consists of studying frost on Mars and whether it indicates the presence of water-ice below the surface.

    JPL and NASA interns are connected through social networks, and it's impressive to see the diversity. Some talks are given by 'JPLers' who make themselves available to answer questions. When I came to JPL, I expected to meet superheroes. This wish has been entirely fulfilled. Working remotely doesn't mean working alone. On the contrary, I think it increases our connections and solidarity."

    Artist's concept of the Perseverance rover on Mars

    Update: July 6, 2020 – Due to processing delays in preparations to unite the spacecraft with the rocket, the first launch attempt will be no earlier than July 30 at 4:50 a.m. PDT (7:50 a.m. EDT). The launch period has been expanded to Aug. 15. Dates updated below. › Read more


    Perseverance, NASA's most advanced Mars rover yet, is scheduled to leave Earth for its seven-month journey to the Red Planet this summer.

    Only the fifth NASA rover destined for Mars, Perseverance is designed to build on the work and scientific discoveries of its predecessors. Find out more about the rover's science goals and new technologies below. Plus, learn how you can bring the exciting engineering and science of this mission to students with lessons and DIY projects covering topics like biology, geology, physics, mathematics, engineering, coding and language arts.

    Why It's Important

    Perseverance may look similar to Curiosity – the NASA rover that's been exploring Mars since 2012 – but the latest rover's new science instruments, upgraded cameras, improved onboard computers and new landing technologies make it uniquely capable of accomplishing the science goals planned for the mission.

    Looking for signs of habitability

    The first of the rover's four science goals deals with studying the habitability of Mars. The mission is designed to look for environments that could have supported life in the past.

    Perseverance will land in Jezero Crater, a 28-mile-wide (45-kilometer-wide) crater that scientists believe was once filled with water. Data from orbiters at the Red Planet suggest that water once flowed into the crater, carrying clay minerals from the surrounding area, depositing them in the crater and forming a delta. We find similar conditions on Earth, where the right combination of water and minerals can support life. By comparing these to the conditions we find on Mars, we can better understand the Red Planet's ability to support life. The Perseverance rover is specially designed to study the habitability of Mars' Jezero Crater using a suite of scientific instruments, or tools, that can evaluate the environment and the processes that influence it.

    Seeking signs of ancient life

    The rover's second science goal is closely linked with its first: Perseverance will seek out evidence that microbial life once existed on Mars in the past. In doing so, the mission could make progress in understanding the origin, evolution and distribution of life in the universe – the scientific field known as astrobiology.

    It's important to note that the rover won't be looking for present-day life. Instead, its instruments are designed to look for clues left behind by ancient life. We call those clues biosignatures. A biosignature might be a pattern, object or substance that was created by life in the past and can be identified by certain properties, such as chemical composition, mineralogy or structure.

    To better understand if a possible biosignature is really a clue left behind by ancient life, we need to look for biosignatures and study the habitability of the environment. Discovering that an environment is habitable does not automatically mean life existed there and some geologic processes can leave behind biosignature-like signs in non-habitable environments.

    Collecting samples

    Perseverance's third science goal is to gather samples of Martian rocks and soil. The rover will leave the samples on Mars, where future missions could collect them and bring them back to Earth for further study.

    Scientists can learn a lot about Mars with a rover like Perseverance that can take in situ (Latin for "on-site") measurements. But examining samples from Mars in full-size laboratories on Earth can provide far more information about whether life ever existed on Mars than studying them on the Martian surface.

    Perseverance will take the first step toward making a future sample return possible. The rover is equipped with special coring drill bits that will collect scientifically interesting samples similar in size to a piece of chalk. Each sample will be capped and sealed in individual collection tubes. The tubes will be stored aboard the rover until the mission team determines the best strategic locations on the planet's surface to leave them. The collection tubes will stay on the Martian surface until a potential future campaign collects them for return to Earth. NASA and the European Space Agency are solidifying concepts for the missions that will complete this campaign.

    Preparing for future astronauts

    Like the robotic spacecraft that landed on the Moon to prepare for the Apollo astronauts, the Perseverance rover's fourth science goal will help pave the way for humans to eventually visit Mars.

    Before humans can set foot on the Red Planet, we need to know more about conditions there and demonstrate that technologies needed for returning to Earth, and survival, will work. That’s where MOXIE comes in. Short for Mars Oxygen In-Situ Resource Utilization Experiment, MOXIE is designed to separate oxygen from carbon dioxide (CO2) in Mars' atmosphere. The atmosphere that surrounds the Red Planet is 96% CO2. But there's very little oxygen – only 0.13%, compared with the 21% in Earth’s atmosphere.

    Oxygen is a crucial ingredient in rocket fuel and is essential for human survival. MOXIE could show how similar systems sent to Mars ahead of astronauts could generate rocket fuel to bring astronauts back to Earth and even create oxygen for breathing.

    Flying the first Mars helicopter

    Joining the Perseverance rover on Mars is the first helicopter designed to fly on another planet. Dubbed Ingenuity, the Mars Helicopter is a technology demonstration that will be the first test of powered flight on another planet.

    The lightweight helicopter rides to Mars attached to the belly of the rover. After Perseverance is on Mars, the helicopter will be released from the rover and will attempt up to five test flights in the thin atmosphere of Mars. After a successful first attempt at lifting off, hovering a few feet above the ground for 20 to 30 seconds and landing, the operations team can attempt incrementally higher and longer-distance flights. Ingenuity is designed to fly for up to 90 seconds, reach an altitude of 15 feet and travel a distance of nearly 980 feet. Sending commands to the helicopter and receiving information about the flights relayed through the rover, the helicopter team hopes to collect valuable test data about how the vehicle performs in Mars’ thin atmosphere. The results of the Mars Helicopter's test flights will help inform the development of future vehicles that could one day explore Mars from the air. Once Ingenuity has completed its technology demonstration, Perseverance will continue its mission on the surface of the Red Planet.

    How It Works

    Before any of that can happen, the Perseverance Mars rover needs to successfully lift off from Earth and begin its journey to the Red Planet. Here's how the launch is designed to ensure that the spacecraft and Mars are at the same place on landing day.

    About every 26 months, Mars and Earth are at points in their orbits around the Sun that allow us to launch spacecraft to Mars most efficiently. This span of time, called a launch period, lasts several weeks. For Perseverance, the launch period is targeted to begin at 4:50 a.m. PDT (7:50 a.m. EDT) on July 30 and end on Aug. 15. Each day, there is a launch window lasting about two hours. If all conditions are good, we have liftoff! If there's a little too much wind or other inclement weather, or perhaps engineers want to take a look at something on the rocket during the window, the countdown can be paused, and teams will try again the next day.

    Regardless of when Perseverance launches during this period, the rover will land on Mars on Feb. 18, 2021, at around 12:30 PST. Engineers can maintain this fixed landing date because when the rover launches, it will go into what's called a parking orbit around Earth. Depending on when the launch happens, the rover will coast in the temporary parking orbit for 24 to 36 minutes. Then, the upper stage of the rocket will ignite for about seven minutes, giving the spacecraft the velocity it needs to reach Mars.

    Like the Curiosity rover, Perseverance will launch from Launch Complex 41 at Cape Canaveral Air Force Station in Florida on an Atlas V 541 rocket – one of the most powerful rockets available for interplanetary spacecraft.

    Farah Alibay, wearing a white lab coat, poses for a photo in front of an engineering model of the Curiosity rover

    It only takes minutes into a conversation with Farah Alibay about her job at NASA's Jet Propulsion Laboratory to realize there's nowhere else she'd rather be. An engineer working on the systems that NASA's next Mars rover will use to maneuver around a world millions of miles away, Alibay got her start at JPL as an intern. In the six years since being hired at the Laboratory, she's worked on several projects destined for Mars and even had a couple of her own interns. Returning intern Evan Kramer caught up with Alibay to learn more about her current role with the Mars 2020 Perseverance rover, how her internships helped pave her path to JPL and how she hopes interns see the same "beauty" in the work that she does.

    What do you do at JPL?

    I’m a systems engineer. I have two jobs on the Mars 2020 Perseverance rover mission right now. One is the systems engineer for the rover's attitude positioning and pointing. It's my job to make sure that once it's on the surface of Mars, the rover knows where it's pointed, and as it's moving, it can update its position and inform other systems of where it is. So we use things like a gyroscope and imagery to figure out where the rover is pointed and where it's gone as it's traveling.

    My other job is helping out with testing the mast [sometimes called the "head"] on the rover. I help make sure that all of the commands and movements are well understood and well tested so that once the rover gets to Mars, we know that the procedures to deploy the mast and operate all of the instruments are going to work properly.

    This is probably a tough question to answer, but what is an average day like for you?

    Right now, I spend a lot of time testing – either developing procedures, executing procedures in the test bed or reviewing data from the procedures to make sure we're testing all of our capabilities. We start off from requirements of what we think we should be able to do, and then we write our procedures to test out those requirements. We test them out with software, and then we come to the test bed to execute them on hardware. Things usually go wrong, so we'll repeat the procedures a few times. Eventually, once we think we've had a successful run, we have a review.

    Most of my testing is on the mobility side. However, it hasn't really started in earnest yet since we're waiting for the rover's "Earth twin" [the engineering model] to be built. Once that happens, later this summer, I will be spending a good chunk of my time in the Mars Yard [a simulated Mars environment at JPL], driving the rover around and actually using real data to figure out whether the software is behaving properly.

    What's the ultimate goal of your work at JPL?

    All the work that I do right now is in support of the Perseverance rover mission. On the mobility team, we work on essential functions that are going to be used as the rover drives around on Mars.

    One of the really neat things about Perseverance is that it can do autonomous driving. So the rover is able to drive up to 200 meters on its own, without us providing any directional information about the terrain. Working on this new ability has been the bulk of testing we're doing on the mobility team. But this new capability should speed up a lot of the driving that we do on Mars. Once we get smart in planning rover movements, we'll be able to plan a day's worth of activity and then tell the rover, "Just keep going until you're done."

    You came to JPL as an intern. What was that experience like and how did it shape what you're doing now?

    I spent two summers as an intern at JPL during my Ph.D. The first one was in 2012, which was the summer that the Curiosity Mars rover landed. That was a pretty incredible experience. As someone who had only spent one summer at NASA before, seeing the excitement around landing a spacecraft on Mars, well, I think it's hard not to fall in love with JPL when you see that happen. During that summer, I worked on the early days of the A-Team [JPL's mission-concept study team], where I was helping out with some of the mission studies that were going on.

    My second summer, I worked in the Mars Program Office, looking at a mission concept to return samples from Mars. I was helping define requirements and look at some of the trade studies. We were specifically looking at designs for orbiters that could bring back samples from Mars. A lot of that fed into my graduate research. It's pretty cool to be able to say that I applied my research and research tools to real problems to help JPL's Mars sample return studies.

    What brought you to JPL for your internship? Was working at JPL always a dream for you?

    Yeah, working at NASA was always a dream, but going into my Ph.D., I became more and more interested in robotics and planetary exploration. I have a Ph.D. in aerospace engineering, but I also have a minor in planetary science. There are very few places on Earth that really put those two together besides JPL, and it's the only place that has successfully landed a spacecraft on Mars. So, given my passions and my interests, JPL emerged at the top of my list very, very quickly. Once I spent time here, I realized that I fit in. My work goals and my aspirations fit into what people were already doing here.

    What moments or memories from your internships stand out the most?

    The Curiosity landing was definitely one of the highlights of my first internship.

    Another one of the highlights is that JPL takes the work that interns do really seriously. I was initially surprised by that, and I think that's true of every intern I've met. Interns do real work that contributes to missions or research. I remember, for example, presenting some of my work to my mentor, who was super-excited about some of the results I was getting. For me, that was quite humbling, because I saw my research actually helping a real mission. I think I'll always remember that.

    How do you think your internship shaped your career path and led to what you're doing now?

    My internships definitely opened a lot of doors for me. In particular, during my second internship, I also participated in the Planetary Science Summer School at JPL. Throughout the summer, we met with experts in planetary science to develop a mission concept, and then we came together as a team to design the spacecraft in one week! It was an intense week but also an extremely satisfying one. The highlight was being able to present our work to some of the leading engineers and scientists at JPL. We got grilled, and they found a whole lot of holes in our design, but I learned so much from it. How often do you get to have your work reviewed by experts in the field?

    Through these experiences, I made a lot of connections and found mentors who I could reach out to. Since I knew JPL is where I wanted to be, I took it upon myself to knock on every single door and make my case as to why JPL should hire me. I actually never interviewed, because by then, they decided that I had done my own interviews!

    My internships and the summer school also gave me an idea of what I wanted to do and what I didn't want to do. So I was a step ahead of other applicants. I always tell interns who come to JPL that if they're not particularly liking their work in the first few weeks, they should take the opportunity to go out and explore what else JPL has to offer. I believe that there's a place for everyone here.

    Have you had your own interns before?

    I had interns my first two summers working at JPL. Two of my interns are now also full-time employees, and I always remind them that they were my interns when I see them! I also have an intern this summer who I'm extremely excited to work with, as she'll be helping us prepare some of the tools we'll need for operating the Perseverance rover on Mars.

    What is your mentorship style with interns?

    My goal for interns is mostly for them to learn something new and discover JPL, so I usually let my interns drive in terms of what they want to achieve. Normally, I sit down with them at the start of summer and define a task, because we want them to be doing relevant work. But I encouraged them to take time off from what they're doing and explore JPL, attend events that we have organized for interns and decide whether this is a place for them or not.

    It's kind of a dual mentorship. I mentor them in terms of doing their work, but also mentor them in terms of helping them evolve as students and as early career engineers.

    What do you hope they take away from their experience?

    I hope they take advantage of this unique place and that they fall in love with it the way I did. Mostly, though, I'm hoping they discover whether this is a place for them or not. Whatever it is, I want them to be able to find their passion.

    What would be your advice for those looking to intern or work at JPL one day?

    I think the way into JPL, or whatever career that you're going to end up in, is to be 100% into what you're doing. If you're in school, studying aerospace engineering or mechanical engineering, do hands-on projects. The way I found opportunities was through the Planetary Science Summer School and the Caltech Space Challenge, which were workshops. I also did something called RASC-AL, which is a different workshop from the National Institute of Aerospace. Do all of those extracurricular things that apply your skills and develop them.

    If you have the opportunity to attend talks, or if your advisor gives you extra work that requires you to reach out to potential mentors, take the time to do it.

    My other piece of advice is to knock on doors and talk to people who do something in your field that you're interested in. Don't be shy, and don't wait for opportunities to come to you. Especially if you're already at JPL, or if you have mentors that are. Leverage that network.

    Last question: If you could play any role in NASA's mission to send humans back to the Moon and eventually on to Mars, what would it be?

    I chose to come to JPL because I like working on robotic missions. However, a lot of these robotic missions are precursors to crewed lunar and Mars missions. So I see our role here as building up our understanding of Mars and the Moon [to pave the way for future human missions].

    I've worked on different Mars missions, and every one has found unexpected results. We're learning new things about the environment, the soil and the atmosphere with every mission. So I already feel like my work is contributing to that. And especially with the Perseverance rover mission, one of its main intentions is to pave the way for eventually sending humans to Mars.

    With microbes capable of living in the harshest environments and life-affirming chemical compounds that can arise from the right mixture of heat and materials, the job of keeping spacecraft as contamination-free as possible is not an easy one. This was the task of French aerospace engineering student Adrien Dias-Ribeiro this past summer when he joined the team building the Perseverance Mars rover as a contamination-control engineering intern. With the rover set to collect the first samples of Martian rock and soil for a possible return to Earth, the team at NASA's Jet Propulsion Laboratory has to ensure the sample-collection system stays "clean" throughout its journey to Mars. We caught up with Dias-Ribeiro to find out how he's contributing to the mission and what brought him to JPL from France.

    What are you working on at JPL?

    I'm working in contamination control engineering for the Perseverance Mars rover mission. I am working, specifically, on the part of Perseverance that is designed to collect samples that could eventually be returned to Earth one day.

    Perseverance is looking to measure the presence of organic carbons, like methane, and search for evidence of past microbial life on Mars, so our job is to be sure that contamination on the rover doesn't interfere with what it's trying to study. All the material [used to build the science instruments on the rover] naturally emits some carbons, so we just try to reduce them as much as possible. We've done several tests on the materials used in the science instruments on the rover. My job is to take the results of the tests and make models to predict whether we're meeting the requirements that are needed. We cannot go above a certain level of contamination or the mission will not meet its requirements.

    What is your average day like?

    It's mostly coding. I take some measurements and I read them in Python [a programming language]. I also read articles about people doing this kind of work and try to improve their models or produce the models at JPL.

    Where do you go to school, and what are you studying?

    I go to ISAE-SUPAERO, the aerospace university in Toulouse, France. I'm studying space engineering.

    What brought you to JPL for this internship?

    I've done another internship in a similar area at the European Space Agency, but I was really interested to be part of the kinds of projects we have at JPL, like the Perseverance rover and Europa Clipper. I also really wanted to work internationally with a different culture than I'm used to. So I got some contacts with my previous supervisors. They knew people working here, so they recommended me.

    I feel really lucky to be at JPL as a French person. One year ago, it was not imaginable that I would be at JPL, so I feel really grateful to be here.

    What is the most uniquely JPL or NASA experience you've had so far?

    I think it's when I was in the clean room [where the Perseverance rover is being built]. I was able to be one meter away from the rover and the descent vehicle [that will help land the rover on Mars].

    Some people on my team had to do some measurements in the clean room and asked if I wanted to go with them, and so I did. I wasn't able to touch anything [laughs]. I just looked. I'm working on models of the rover, so it was really interesting to go closer to the hardware and the real spacecraft. I'd also never been inside the clean room before.

    How do you feel you are contributing to the mission and making it a success?

    I feel really lucky because the job I'm doing now will be directly applied to ensuring that the mission meets its requirements, which is to not go above the limit of organic carbon emitted by the hardware in charge of collecting the samples.

    What is your ultimate career goal?

    I'm really interested in systems engineering, so I'm trying to learn as much as possible about different types of engineering, modeling and how to manage projects.

    If you could play any role in NASA's plans to send humans back to the Moon or on to Mars, what would you want to do?

    I guess a lot of people would say, "Be an astronaut," but I really like living here on Earth, so I think I wouldn't really want to be an astronaut. If I could ensure the safety of the astronauts going to the Moon or Mars, that's the kind of job I would like to do.

    Tiffany Shi poses for a photo in front of a steel and glass building at JPL with the words "Flight Projects Center" displayed on the front of the building.

    Deciding where to land on Mars has always meant striking the right balance between potential science wins and the risk of mission failure. But new technology that will allow NASA's next Mars rover, Perseverance, to adjust its trajectory to the safest spot within an otherwise riskier landing area is giving science its biggest edge yet. This past summer, it was intern Tiffany Shi's task to help prepare the new technology, called the Lander Vision System, for its debut on Mars. Analyzing data from test flights in California's Death Valley, the Stanford University student joined the team at NASA's Jet Propulsion Laboratory to make sure the new landing system will work as designed, guiding the Perseverance rover to a safe landing as the spacecraft speeds toward the surface into Mars' Jezero Crater. We caught up with Shi to find out what it was like to work on the technology, how she managed the 8-to-5 and how she found a new approach to problem-solving.

    What are you working on at JPL?

    I'm working with the Mars 2020 mission, building the lander system for the Perseverance Mars rover. This is new technology in that [as the rover is landing on Mars] it is going to be able to look down at the surface below and figure out where is the safest place to land within the chosen area. Because of this technology, we're going to be able to land in a place that's more geologically and scientifically interesting than anywhere else we've been on Mars.

    How did previous Mars landings work?

    Before, it was only really safe to land if we picked a huge, flat area and programmed the spacecraft to land somewhere in there. But for the Mars 2020 mission, the spacecraft will take images of the terrain below as it descends into the atmosphere and will match those images to reference maps that we have from the work of previous missions. This will allow us to autonomously detect potential landing hazards and divert our spacecraft from them. In other words, the spacecraft is going to be able to look below and find the safest place to land in an area that's generally more hazardous [than what previous rovers have landed in].

    What is your average day like on the project?

    My average day consists of coming here at 8. That is very new for me [laughs]. I sit in the basement with two office mates, and we each work on our own things. I'm doing error analysis to find any bugs in the Lander Vision System, which is what will be used to land the rover on Mars. The algorithm for the landing system is pretty much written, and I'm analyzing the field-test data that they got from the tests that were done in Death Valley in February. Both my office mates are also working on the Lander Vision System, but they're not on the same exact project. They are all super-nice and helpful, and we all talk about our work, so it's a lot of fun.

    Tell me more about the field tests and how you're analyzing the results.

    In February, the team took a helicopter and they attached a copy of the Lander Vision System to the front. The helicopter did a bunch of nosedives and spirals over the terrain, which is really similar to what the rover will see on Mars. The goal is to see how accurate our predictions are for our algorithm relative to our reference maps. We're using the tests to improve our algorithm before the spacecraft launches.

    What are you studying at Stanford?

    I'm not sure what my major will be yet. I don't have to declare it until the end of my second year. I've only just finished my freshman year. I'm thinking maybe computer science or a mix of computer science and philosophy, because I really like both.

    What got you interested in those majors?

    I did debate in high school, and a lot of debaters use philosophy to argue different perspectives. So that's what got me started.

    What about the computer science side?

    I was in Girls Who Code while I was in high school, and there were JPL mentors who came to my school every Friday and taught us everything that we wanted to know. It was a super-fun place, super-inclusive. You see a lot of shy girls who don't normally talk in classes really open up. They had great debates, great questions, and it was just really cool to see.

    Had you had any experience coding before that?

    No, but I started taking some classes after that, and I did an internship at Caltech my junior year.

    What was the internship at Caltech?

    It was actually with Christine Moran, who now works at JPL. When she was doing her postdoc at Caltech, she brought in 12 high-school student interns through a program called Summer App Space. I worked in a team that classified galaxies into 36 different categories using training and test images from an online machine-learning community.

    Very cool! What has been the most uniquely JPL or NASA experience that you've had while you've been here?

    I went to see the rover being built in the clean room with my mentor, and that was just surreal. Even though I am sure my contributions are going to be very small, I think it's wild that I am actually working on something that's going to Mars.

    Has your internship opened your eyes to any potential career paths?

    I haven't taken any aeronautics and astronautics classes, and I think I might see if I'm interested in studying that. It is so interesting working on something that is literally going to be in space. In college, you have an answer to work towards, and here you are finding the answer. I think I didn't really process what I was going to be doing before coming here.

    Eventually, I know I want to go into computer science, but also I want to go into maybe social impact work. I'd love to find some intersection between those. I feel like I grew up really privileged, so I want to use my skills to help other people. But I do love computer science or something where I'd be really at the forefront of research.

    If you could play any role in NASA's plans to send humans back to the Moon or on to Mars, what would you want to do?

    Be there. I met Jessica Watkins, who used to intern here, and now she's one of the new NASA astronauts. She spoke to us during my Caltech internship. It was super surreal meeting her. So if I could play any part, I'd want to be up there.

    Update: March 16, 2020 – The answers to the 2020 NASA Pi Day Challenge are here! View the illustrated answer key (also available as a text-only doc).


    In the News

    Our annual opportunity to indulge in a shared love of space exploration, mathematics and sweet treats has come around again! Pi Day is the March 14 holiday that celebrates the mathematical constant pi – the number that results from dividing any circle's circumference by its diameter.

    Besides providing an excuse to eat all varieties of pie, Pi Day gives us a chance to appreciate some of the ways NASA uses pi to explore the solar system and beyond. You can do the math for yourself – or get students doing it – by taking part in the NASA Pi Day Challenge. Find out below how to test your pi skills with real-world problems faced by NASA space explorers, plus get lessons and resources for educators.

    How It Works

    The ratio of any circle's circumference to its diameter is equal to pi, which is often rounded to 3.14. But pi is what is known as an irrational number, so its decimal representation never ends, and it never repeats. Though it has been calculated to trillions of digits, we use far fewer at NASA.

    Pi is useful for all sorts of things, like calculating the circumference and area of circular objects and the volume of cylinders. That's helpful information for everyone from farmers irrigating crops to tire manufacturers to soup-makers filling their cans. At NASA, we use pi to calculate the densities of planets, point space telescopes at distant stars and galaxies, steer rovers on the Red Planet, put spacecraft into orbit and so much more! With so many practical applications, it's no wonder so many people love pi!

    In the U.S., 3.14 is also how we refer to March 14, which is why we celebrate the mathematical marvel that is pi on that date each year. In 2009, the U.S. House of Representatives passed a resolution officially designating March 14 as Pi Day and encouraging teachers and students to celebrate the day with activities that teach students about pi.

    The NASA Pi Day Challenge

    This year's NASA Pi Day Challenge poses four puzzlers that require pi to compare the sizes of Mars landing areas, calculate the length of a year for one of the most distant objects in the solar system, measure the depth of the ocean from an airplane, and determine the diameter of a distant debris disk. Learn more about the science and engineering behind the problems below or click the link to jump right into the challenge.

    Mars Maneuver

    Long before a Mars rover touches down on the Red Planet, scientists and engineers must determine where to land. Rather than choosing a specific landing spot, NASA selects an area known as a landing ellipse. A Mars rover could land anywhere within this ellipse. Choosing where the landing ellipse is located requires compromising between getting as close as possible to interesting science targets and avoiding hazards like steep slopes and large boulders, which could quickly bring a mission to its end. In the Mars Maneuver problem, students use pi to see how new technologies have reduced the size of landing ellipses from one Mars rover mission to the next.

    Cold Case

    In January 2019, NASA's New Horizons spacecraft sped past Arrokoth, a frigid, primitive object that orbits within the Kuiper Belt, a doughnut-shaped ring of icy bodies beyond the orbit of Neptune. Arrokoth is the most distant Kuiper Belt object to be visited by a spacecraft and only the second object in the region to have been explored up close. To get New Horizons to Arrokoth, mission navigators needed to know the orbital properties of the object, such as its speed, distance from the Sun, and the tilt and shape of its orbit. This information is also important for scientists studying the object. In the Cold Case problem, students can use pi to determine how long it takes the distant object to make one trip around the Sun.

    Coral Calculus

    Coral reefs provide food and shelter to many ocean species and protect coastal communities against extreme weather events. Ocean warming, invasive species, pollutants, and acidification caused by climate change can harm the tiny living coral organisms responsible for building coral reefs. To better understand the health of Earth's coral reefs, NASA's COral Reef Airborne Laboratory, or CORAL, mission maps them from the air using spectroscopy, studying how light interacts with the reefs. To make accurate maps, CORAL must be able to differentiate among coral, algae and sand on the ocean floor from an airplane. And to do that, it needs to calculate the depth of the ocean at every point it maps by measuring how much sunlight passes through the ocean and is reflected upward from the ocean floor. In Coral Calculus, students use pi to measure the water depth of an area mapped by the CORAL mission and help scientists better understand the status of Earth's coral reefs.

    Planet Pinpointer

    Our galaxy contains billions of stars, many of which are likely home to exoplanets – planets outside our solar system. So how do scientists decide where to look for these worlds? Using data gathered by NASA's Spitzer Space Telescope, researchers found that they're more likely to find giant exoplanets around young stars surrounded by debris disks, which are made up of material similar to what's found in the asteroid belt and Kuiper Belt in our solar system. Sure enough, after discovering a debris disk around the star Beta Pictoris, researchers later confirmed that it is home to at least two giant exoplanets. Learning more about Beta Pictoris' debris disk could give scientists insight into the formation of these giant worlds. In Planet Pinpointer, put yourself in the role of a NASA scientist to learn more about Beta Pictoris' debris disk, using pi to calculate the distance across it.

    Vivian Li holds a computer and poses for a photo in front of a full-size model of the Mars rover Curiosity.

    To remotely operate NASA's next Mars rover on a planet millions of miles away, mission team members will need to carefully plan out every drive, head swivel and arm extension before sending their coded commands to the vehicle. A wrong move could jeopardize the mission and, at the least, eat into the rover's precious energy supply. So this past summer, it was intern Vivian Li's task to design a web tool that will let mission operators ensure they're sending all the right moves to Mars. The internship at NASA's Jet Propulsion Laboratory gave Li, an information and computer science major at Cornell University, a chance to bring her design skills to a team that's typically more focused on building interfaces for robots rather than for humans. We caught up with Li to learn how she's adding a human touch to robotic navigation on the Mars 2020 mission.

    What are you working on at JPL?

    I'm working on a user interface for the Mars 2020 rover that takes in commands and produces a 3D simulation of the commands. So a rover driver could input what they want the rover to do – for example, drive 100 meters forward – and then, based on the terrain and all the other external factors, the program would take in the commands and simulate the path of the rover.

    Is this something completely new for Mars 2020?

    They've had the simulation software for a really long time. This is just a different way to package it and for people to be able to easily use it. The current version only runs on certain computers, so we're moving it to a web-based platform that can run on pretty much any modern browser.

    What's your average day like at JPL?

    I get in around 7:30 a.m., and at that time I just sort of warm up for the day in that I don't do anything that's super-taxing. I check my meetings and get set up. Then right after that, I jump into what I need to do. Right now, my primary project is creating the front end for the interface, writing a little bit of code and fixing bugs in the flight software simulation for Mars 2020.

    If I'm not in meetings, I'll be writing code all day and doing a lot of planning. I'm in a different office than my team, so me and my co-intern will sometimes ask for help with our project, but it's a lot of independent work. It's great because my co-intern and I help each other a lot. Our mentors tell us what they want – like yesterday, they wanted us to incorporate a camera view into the simulation – then, we're the ones who figure out how to do it.

    Pretty soon, we'll be going into user testing. There are a couple of people who would actually be using the technology who volunteered to test it out. Once they do, we can edit it based on how they feel about what we have right now.

    What has been the most uniquely JPL or NASA experience that you've had so far?

    Two things: First, just getting to stroll in and watch the Mars 2020 rover being built in the clean room. Second is meeting the people who work here. The people here all share a similar love of science and exploration research, which is really different from how a lot of computer science is oriented. All the engineers and even people who are in physics or communications share a common goal. I've learned so much from just talking to people and even other interns. It's been so cool, because I don't really get that exposure at school.

    What made you decide to study information and computer science?

    I actually went into college studying biology and English. I had done a year of coding in my senior year of high school, so I knew a little bit of [the programming language] Python. When I got to college, I decided to study biology, and I kind of started orienting toward computational biology. I worked in a lab, and the people there told me, "If you have computer science skills, you can kind of go into any field you want." So I had this career crisis moment when I was like, "I don't want to study biology anymore," because I had been in a microbiology lab all summer and it was not very fun. I figured if I did computer information sciences, it would give me more time to decide.

    Even though I know a lot of people here have a lot more experience than me and they started a lot younger, I feel like my skills are so much more adaptable now, and that is what made me stay in the major.

    So you still wanted to have that science focus?

    Yeah. I don't want to fully isolate myself from the thing that I wanted to study originally, because I still do love biology, just not the career path that goes with it.

    What about the user-interface side? Is that something that you're interested in, or did you get thrown into it for your internship?

    That's what's special about my major in computer information science: Not only are we technically-based, but also we're user-and-society-based. So for our core classes, we take communications, law, ethics and policy, and all that. Through all those classes, I learned just how important the user-interface side is and accessibility design, and just how much easier life gets if the engineer really understands the user. I think having a good understanding of society and technology is what we should all be focusing on.

    Are you bringing some of that user focus to your work with the Mars 2020 mission?

    With my mentors being more on the software side and my co-intern being more on the development side, I think my having the user-interface design skills is unique in a very technical workspace. For Mars 2020, even though I'm not working on the design of the rover or one of the software systems, being here allows me to reinforce that the users are still really important, and we want to make it as easy as possible for someone to understand the technology even though it's super-complex.

    What brought you to JPL for this internship?

    A year and a half ago, I went on a trip to Texas with my friend from school. She brought her friend from home, who brought his friend. The two of them had interned at JPL. They spent the entire week talking about JPL nonstop, on all of our hikes [laughs]. I had never met people who loved their work so much that they wanted to talk about it 24/7. That made me think that JPL must be a great workplace and somewhere that everyone is really passionate. Since then, I've just wanted to come here.

    How do you feel you're contributing to the Mars 2020 mission and making it a success?

    I feel like the work I am doing is really important. And because I'm bringing a unique skill set to my team, it makes me feel like I'm valued at JPL. I've also been working with other teams who might also want to use my software. Because of that, I think that this concept could be developed for other missions and be really useful in the future as well.

    What is your ultimate career goal?

    I don't know yet. I just really wanted to work at JPL this summer because I felt like I would get exposed to a lot more. I think now I'm more stressed, because I have seen so many things I want to do [laughs]. But I definitely want to be somewhere in the realm of tech and society. My overarching goal is that I want to have an ethical career, something that can help humanity. And I think JPL is doing that.

    If you could play any role in NASA's plans to send humans to the Moon or on to Mars, what would it be?

    I really enjoy the work I'm doing now and would love to continue doing that in the future. I don't think I personally want to be an astronaut. I want to stay on Earth for everything that this planet has to offer.
