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."

"Our team is using radar data [from the European Space Agency’s Mars Express spacecraft] to find out what lies beneath the large icy deposits on Mars' south pole. My average day consists of analyzing this radar data on my computer to find and map the topography of an older surface that lies below the ice on Mars’ south pole, while my plants look on approvingly.

I was delighted to be offered the chance to work at JPL again. (This is my fourth JPL internship.) Even though it's better to be 'on lab,' it is an honor to get to learn from the coolest and smartest people in the world."

"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."

"I am working on the Psyche mission as a member of the Assembly Test and Launch Operations team, also known as ATLO. (We engineers love our acronyms!) 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."

My 'office setup' is actually just a board across the end of my bed balanced on the other side by a small dresser that I pull into the middle of the room every day so that I can sit and have a hard surface to work on.

At first I wasn't sure if I was interested in doing a virtual engineering internship. How would that even work? But after talking to my family, I decided to accept. Online or in person, getting to work at JPL is still a really cool opportunity."

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."

"I am investigating potential spacecraft trajectories to reach the water worlds orbiting the outer planets, specifically Jupiter's moon Europa. If you take both Jupiter and Europa into account, their gravitational force fields combine to allow for some incredibly fuel-efficient maneuvers between the two. 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! We plan to use the GPU to speed up my work this summer as well. I have my laptop connected to a second monitor up in the loft of the cabin where my wife and I are staying. We just had a baby two months ago, so I have to make the most of the quiet times when he's napping!"

"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 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."

"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.

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.

Side-by-side satellite and data images of soil moisture, flooding, temperature, a snowstorm, a wildfire and a hurricane

In the News

An extreme weather event is something that falls outside the realm of normal weather patterns. It can range from superpowerful hurricanes to torrential downpours to extended hot dry weather and more. Extreme weather events are, themselves, troublesome, but the effects of such extremes, including damaging winds, floods, drought and wildfires, can be devastating.

NASA uses airborne and space-based platforms, in conjunction with those from the National Oceanic and Atmospheric Administration, or NOAA, to monitor these events and the ways in which our changing climate is contributing to them. Together, the agencies are collecting more detailed data on weather and climate than ever before, improving society's ability to predict, monitor and respond to extreme events.

NASA makes this data available to the public, and students can use it to understand extreme weather events happening in their regions, learn more about weather and climate in general, and design plans for resilience and mitigation. Read on for a look at the various kinds of extreme weather, how climate change is impacting them, and ways students can use NASA data to explore science for themselves.

How It Works

Global climate change, or the overall warming of our planet, has had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up and melting earlier in the year, precipitation patterns have changed, plant and animal habitat ranges have shifted, and trees are flowering sooner, exposing fruit blossoms to damaging erratic spring hail and deadly late frost. Effects that scientists had predicted in the past are now occurring: loss of sea ice, accelerated sea level rise, shifting storm patterns and longer, more intense heat waves.

Some of the most visible and disruptive effects of global climate change are extreme weather and resulting disasters such as wildfires and flooding. These events vary by geographic location, with many regions, such as the Southwest United States and parts of Central and South America, Asia, Europe, Africa and Australia, experiencing more heat, drought and insect outbreaks that contribute to increased wildfires. Other regions of the world, including coastal areas of the United States and many island nations, are experiencing flooding and salt water intrusion into drinking water wells as a result of sea level rise and storm surges from intense tropical storms. And some areas of the world, such as the Midwestern and Southern United States, have been inundated with rain that has resulted in catastrophic flooding.

Temperatures, rainfall, droughts, high-intensity hurricanes and severe flooding events all are increasing and projected to continue as the world's climate warms, according to the National Climate Assessment. Weather is dynamic and various types of weather can interact to produce extreme outcomes. Here's how climate change can play a role in some of these weather extremes.

High Temperatures

Eighteen of the 19 warmest years on record have occurred since 2001. September 2019 tied as the hottest month on record for the planet. Since the 1880s, the average global surface temperature has risen about 2 degrees Fahrenheit (1 degree Celsius). As a result of warming temperatures, global average sea level has risen nearly 7 inches (178 millimeters) over the past 100 years. Data show this warming of the Earth system has been driven in large part by increased emissions into the atmosphere of carbon dioxide and other greenhouse gases created by human activities. And as temperatures continue to rise, we can expect more extreme weather.

Drought and Wildfires

High temperatures alone can lead to drought. Drought can cause problems for humans, animals and crops dependent on water and can weaken trees, making them more susceptible to disease and insect attacks. High temperatures combined with low humidity, dry vegetation and hot, dry, fast winds typify what is known as "fire weather" or "fire season." During fire season, wildfires are more likely to start, spread rapidly and be difficult to extinguish.

In California, where climate change has brought hotter, drier weather, residents are plagued by two fire seasons – one lasting from June through September that is primarily caused by high heat, low humidity and dry vegetation, and another lasting from October through April that is generally more volatile, as it is fueled by high winds. This 11-month fire season is longer than in past years. In recent years, California has also seen an increase in destructive wildfires. Weather extremes and climate change are partly to blame, even in relatively wet years. In California, these years mean more plant growth and potentially more fuel for fires when those plants dry out in the fall and the winds arrive. Wildfires have some fairly obvious effects on people and property. In addition to the visible destruction, smoke from wildfires can dramatically decrease air quality, pushing carbon into the air and destroying important carbon-sequestering plants and trees. Large-scale biomass destruction, as is happening in the Amazon rainforest, will have a lasting impact on important Earth processes.

Hurricanes

Since the 1980s, regions of the world prone to hurricanes, cyclones and typhoons have witnessed an increase in intensity, frequency and duration of these destructive storms. All three are intense tropical storms that form over oceans. (The different names refer to where on Earth they occur.) They are all fueled by available heat energy from warm ocean water. Warmer oceans provide more energy to passing storms, meaning hurricanes can form more quickly and reach higher speeds. Typhoon Hagibis, which recently left a trail of destruction in Japan, was described as the worst storm to hit the region in decades. Growing unusually quickly from a tropical storm to a Category 5 storm in less than a day, Hagibis was so intense it was called a super typhoon. In 2018, the second strongest cyclone to hit a U.S. territory and the largest typhoon of the year, Super Typhoon Yutu, caused catastrophic destruction on the Mariana Islands, an archipelago in the North Pacific Ocean. More intense storms and rising sea levels make storm surge – ocean water that is pushed toward the shore by strong winds – even worse than in the past. Typhoons can wreak havoc on infrastructure and compromise fresh water reserves. It can take months or even years for a hard-hit region to recover.

Snowstorms

Like any other weather event, extreme cold weather events such as blizzards and unusually heavy snowfall can be, but are not always, linked to climate change. Just as warmer ocean water increases the intensity of a warm tropical storm, warmer than average winter ocean temperatures in the Atlantic feed additional energy and moisture into cold storms, influencing the severity of snowfall once the storm comes ashore in the Eastern United States. There is some natural variability, such as the presence of El Niño conditions, that can also lead to severe snowstorms in the region. But natural variability isn't enough to fully explain the increase in major snowstorms in the U.S. In fact, the frequency of extreme snowstorms in the eastern two-thirds of the region has increased dramatically over the last century. Approximately twice as many extreme snowstorms occurred in the U.S. during the latter half of the 20th century as in the first half.

Why It's Important

Because of the risk to lives and property, monitoring the increasing number of extreme weather events is more important now than ever before. And a number of NASA satellites and airborne science instruments are doing just that.

A large global constellation of satellites, operated by NASA and NOAA, combined with a small fleet of planes operated by the U.S. Forest Service, help detect and map the extent, spread and impact of forest fires. As technology has advanced, so has the value of remote sensing, the science of scanning Earth from a distance using satellites and high-flying airplanes. Wildfire data from satellites and aircraft provide information that firefighters and command centers can use to call evacuation orders and make decisions about where to deploy crews to best arrest a fire's progress.

The agencies' satellites and airborne instruments also work in conjunction with those from international partners to provide data about hurricanes to decision makers at the National Hurricane Center, where predictions and warnings are issued so evacuations can be coordinated among the public and local authorities. Visible imagery from NASA satellites helps forecasters understand whether a storm is brewing or weakening based on changes to its structure. Other instruments on NASA satellites can measure sea surface characteristics, wind speeds, precipitation, and the height, thickness and inner structure of clouds.

NASA's airborne instruments, such as those aboard the Global Hawk aircraft, provide data from within the storm that cannot be otherwise obtained. Global Hawk can fly above a storm in a back-and-forth pattern and drop instruments called dropsondes through the storm. These instruments measure winds, temperature, pressure and humidity on their way to the surface. This detailed data can be used to characterize a storm, informing scientists of shifting patterns and potential future developments.

NASA missions will continue to study both weather and climate phenomena – whether they be droughts, floods, wildfires, hurricanes or other extremes – returning data for analysis. New airborne instruments aboard the satellite-simulating ER-2 and cloud-penetrating P-3 aircraft will fly missions starting in 2020 to study Atlantic coast-threatening snowstorms. Data from these flights will be combined with ground-based radar measurements and satellite measurements to better understand storms and their potential impact. Meanwhile, climate science instruments and satellites will continue to collect data that can inform everyone about the many aspects of our changing planet.

Jarod Boone poses in front of a mural at JPL

With wildfires around the world occurring increasingly often and burning over a longer portion of the year, scientists at NASA's Jet Propulsion Laboratory are working to understand whether the blazes could have long-term impacts on global climate change. In some respects, it’s a tough question to answer – not because of an absence of data, but because of an overabundance. That’s where intern Jarod Boone, a computer engineering student at Brown University, comes in. As part of a program at JPL that brings together designers, computer programmers and scientists to answer data-heavy science questions using visualizations, Boone spent this summer helping climate researchers visualize tens of thousands of files containing wildfire data collected by instruments on NASA’s Terra satellite. Boone shared what it was like visualizing wildfire data as more than a dozen wildfires burned across California (where JPL is located) and how he never quite got used to JPLers’ tendency to speak in acronyms.

What are you working on at JPL?

I'm doing the programming for a data visualization tool to help researchers who are using the Terra satellite analyze wildfire data and how high these fires inject into the atmosphere. That's a question scientists are really concerned with because you have all these fires burning up matter, and all the matter that they burn goes into the air and just floats around for many, many days afterward. We don't really know how exactly that affects global climate change, so it's good to take a look at the data.

Have you discovered anything so far from these visualizations?

Not quite yet. So the [Data to Discovery Visualization Program] that I’m a part of is sort of a unique program here at JPL. We have two designers and three computer science teams, and we have three projects that we work on. It's very design focused. So in the course of my projects, we have several weeks of what we call contextual inquiry, which is going in and doing interviews, creating prototypes and basically trying to get an idea of what scientists do for their workflow, because it’s kind of hard to conceive of what you would do to answer a scientific question if you don't have a scientific background. So we spend a lot of time getting to know what the scientists are trying to accomplish. We're trying to make the best interface possible for them to use this data. That's actually a huge problem in science: There's a huge barrier to entry with a lot of these data sets, so it discourages things like exploratory science.

Have you been adding all the recent wildfires in the western U.S. to your data set?

I'm mostly working with older fires because it takes a bit of time to digitize the fires that are imaged by the Terra satellite. They have to go through this process where they take a bunch of images of the fire – because you have these flat images and you're trying to get plume height and the satellite is moving – and they essentially need to stitch together the images of the fire to get an idea of how high the smoke plume is, which is quite a process. And it has to be done one by one. But there are enough older fires for us to work with.

You're from Massachusetts, a state that doesn't have a lot of wildfires. Has being in Southern California during all the wildfires this summer changed your perspective on how to go about these visualizations?

It's a little hard because the visualizations and working with all the satellite data is so detached, and they're really abstracted away from any actual fires. So it's like I'm just seeing all these data points and getting all these data products, like optical depth. I don't really know what that is, so when I see a real fire, I'm like, "Whoa, that's what that is." But there's not really a huge cognitive connection. It's definitely cool to be able to work with something that's pretty pertinent and definitely a problem in California.

What's the ultimate goal of the project both for you and for JPL?

For JPL, it is to refine our ideas of climate models and better take fires into account. The global climate models right now do a fairly poor job of taking fires into account because it's really difficult. They happen so sporadically. It's not a fluid weather system. It's these discrete fires, and they're just huge dumps of energy. How do we account for that? So that's definitely the end goal for JPL.

I am not a climate scientist. I will not be doing any updates to the climate models, but I do hope to encourage exploratory research. And I'm sort of trying to introduce principles of design and human-centered interfacing and accessibility to climate scientists. Actually, one of my mentors was very excited about what I was working on and had me submit an abstract for the [American Geophysical Union Fall Meeting]. So visualizing is important. You should be able to conceive of the data you're using.

How did you get involved in the program that brought you to JPL to do this work?

I had done a lot of visualization work at my school. Not on purpose, tangentially. I worked at the Brown University Center for Computation and Visualization, so we had a lot of people coming in wanting to do some kind of research visualization and they had a lot of technical problems. So I sort of got sucked into the visualization and research-aid world. One of my bosses knew Santiago Lombeyda, one of the mentors in this program from Caltech, and he said he was looking for data visualization students who were well versed in that and able to do computer science. JPL seemed pretty cool, so I decided to apply.

What are you thinking you want to do eventually?

So long, long term, I have this vision of humanizing computer systems. A lot of software developers don't know entirely how systems work. A lot of consumers are still confused by computers, and we're still using a bunch of folders spread out to represent files rather than something more intuitive or something that represents the data better. The fact that most users need to troubleshoot online to figure out how to use their computer and answer how to fix certain problems is a problem. I feel like we know enough about computers at this point and this generation is, in general, literate enough about computer science to be able to understand what's going on. We can possibly do a lot better making operating systems transparent. That's what I would like to do. I think that would be a cool project.

Is there a particular place that you'd want to do that?

In practice, I would just like to work a little bit in industry, doing systems development either in hardware or software. It's really cool to work with a data system like this, a satellite that has a lot of nuanced issues with how you get the data and what you can do with the data and how you transmit it back and forth and, at the end, what you do with that data problem.

What's an average day like for you?

So we actually split up a decent amount of our time between here and Caltech [which manages JPL for NASA]. Most days I'll have meetings with our research groups just to touch base and see what's happening. On Mondays, we'll have [critiques] all day, which is where our mentors review our projects up to that point. Then, pretty much the rest of the day I'll spend meeting with my designers and programming. Sometimes I go for walks or explore the campus a little bit. But most of the time, I'm just holed up doing the computer thing.

What's been the most JPL or NASA unique experience you've had so far?

During the second meeting that I had with my mentor, Abigail Nastan, she used like five acronyms in the same sentence. And I was just, "Can you just use words?" [Laughs.] You guys should just have an acronyms cheat-sheet for interns.

Also, going to the Mars Yard, sitting in the rocks. Every experience here is a NASA experience.

If you could travel to any place in space, where would you go and what would you do there?

In space? I mean, Earth is really cool. I guess I'd probably go to Jupiter, just because something fishy is going on there. [Laughs.] That planet is too big. Also, I just don't trust gas giants. What do you mean, you don't have a surface? I definitely would not go on Jupiter – I'd just watch it from afar.

Vicky Espinoza stands in front of an Earth science display at JPL

In the science world, publishing a paper is a big deal; it’s how scientists share their discoveries with the world. So it’s no small feat that Vicky Espinoza published her first science paper as an intern at NASA’s Jet Propulsion Laboratory. In the paper, her team takes a look at the effects of climate change on global atmospheric rivers, which bring an onslaught of snow and rain to affected areas and have serious implications for people who live there. The Earth science student from the University of California, Merced, met with us this summer to share how she’s helping her team take the research further and what it’s like to be an intern at JPL.

What are you working on at JPL?

We're studying how atmospheric rivers – which are long jets of water vapor – move through the Earth system and identifying key physical properties that characterize their frequency and magnitude. We’re doing this by taking what we currently know about atmospheric rivers and contrasting it with “aqua planet” model simulations, changing one physical parameter at a time. An aqua planet is a theoretical planet that has the same dynamic and thermodynamic properties as Earth’s atmosphere and oceans, but with the continents removed. We’re also observing how climate change and these parameter changes combine to impact the physical characteristics, frequency and magnitude of atmospheric rivers in these aqua-planet scenarios.

Tell me more about atmospheric rivers and the impacts that they have on our climate.

There is a certain geometry to them that separates them from other storm types. They often tap moisture in the tropics and transport it toward the poles and into and across mid-latitudes. An important feature of them is that they often make landfall on the western coasts of continents – so the mountainous regions like the Sierras and the Andes. When the warm, moist air rises to cross the mountains, it cools down and precipitates out as either snow or rain, depending on the temperature. Just to give you a sense of how much water they can hold, a single atmospheric river can transport 25 Mississippi Rivers of water as water vapor. So the implications are that they can cause severe flooding, or in their absence, they can cause drought periods. So they're very important for water management, especially for regions like California that depend on precipitation for water.

You were the lead author on a science paper published recently on this topic.

Yes. It’s a global analysis of climate-change projection effects on atmospheric rivers. It was the first paper that performed such an analysis on atmospheric rivers on a global scale. My mentors, Bin Guan and Duane Waliser here at JPL, created an atmospheric-river detection algorithm, which we used to identify and compare atmospheric rivers globally. We found that with climate change, these atmospheric rivers will occur 10 percent less, but they will be 25 percent wider and stronger. Because the rivers will be more expansive, a given area will experience atmospheric-river conditions up to 50 percent more often despite there being fewer atmospheric river events. Also, the frequency of the strongest of these atmospheric rivers is going to double. It has so many implications for water managers and those living in atmospheric-river-prone regions who will need to start preparing or start thinking about the implications of these large storms.

Is this the first time that you've been an author on a paper?

Yes, it's the first time I've published a paper. My mentors made me first author, which was such a great experience. It was a lot of work. As a Ph.D. student now, it's fruitful to know what it means to be an author of a paper.

What did it mean for you to be able to publish a paper as an intern?

Just being so passionate about a topic, putting your hard work and soul into a paper and then seeing it become reality is – it's something different. I can't even describe it. It makes me feel like I've accomplished something.

What are you studying for your doctorate?

I'm taking a look at water management and sustainable water uses in agricultural regions in California.

Are you hoping to eventually work at JPL?

Yes. JPL has been a dream. I actually applied to JPL three times before I got an internship. I applied as an undergrad, and then during my master's I was, like, “Let me try one more time. Let's give it a go.”

It's been such a great experience to intern here. One of the things that I love about JPL is that everyone is so passionate and creative. It's like Disneyland for scientists. It's very motivating to meet people in line for coffee and be like, “Oh, you work on the Hubble Space Telescope? No big deal.” And they're just so grounded and so passionate, and everyone's willing to talk to you. So it's been a great experience.

What's the most unique JPL or NASA experience that you've had?

I think the overall experience has been unique. I haven't been in a work environment where the majority of people are so happy to be here and everyone is just so passionate and driven.

What's a typical day like for you?

A typical day for me is behind the computer, so taking a lot of data and running it through a detection algorithm and running a statistical analysis on the data, creating figures and analyzing these atmospheric-river trends.

How do you think that what you're working on might help the average person one day?

Taking a look at this theoretical aqua planet, [a simulated version of Earth with the continents removed], and changing differing parameters of these atmospheric rivers is bringing fundamental insight into how they function, develop and move across the globe. I think that this work will inform citizens, stakeholders, policy makers and water managers on the future of California water.

What got you interested in science in the first place?

I feel like I've been doing science for a long time. My dad works in hydrology, so I've always been exposed to that. But I've always been someone very curious, especially about climate change. I started with air quality and how climate change is impacting the atmosphere. The atmosphere and ocean are connected in some ways, so I started exploring the ocean through an internship. Just being curious about our planet has led me to where I am now.

If you could travel to any place in space, where would you go and what would you do there?

I am a fan of rogue planets, or floating planets. There's an [Exoplanet Travel Bureau] poster that imagines them as planets where people would go dancing. I would want to go to a rogue planet just to figure out what it's like. They don't have a parent star, so they're just out there on their own and there's something so serene and somewhat romantic about that.

Amanda Allen holds out a rock containing a microfossil in front of the science building at JPL.

To prepare her team to analyze the first sample returned from Mars in the future, JPL intern Amanda Allen is exploring how she can get the biggest science from the smallest places. We caught up with Allen, an Earth science major at UC San Diego who also has a background in costume design, to find out what the tiniest and rarest fossils could tell us about ancient life on Earth – and beyond.

What are you working on at JPL?

I am trying to develop a method to analyze the isotopic ratios of organic carbon preserved in individual microfossils.

Say again?

As living creatures on Earth, one of the most important elements to us is carbon. When we eat food, we are adding carbon to our bodies, and depending on what we eat and where we live, we get different types of carbon, which are called isotopes. Some isotopes are heavier than others, but living organisms have a tendency to process the lighter ones, which we can measure as a ratio.

When a creature dies, and if it becomes a fossil, any carbon that is preserved will hold a record of its isotope ratio. If we can get that fossil, we can use a mass spectrometer instrument to separate the lighter and heavier isotopes to see what that ratio is. Then we can use that to figure out what sort of lifestyle and eating habits the organism had.

JPL Interns

But usually, you don’t get a single fossil. Sometimes your sample is what was once sludge at the bottom of a lake, and that makes it difficult to study a specific fossil because there are lots of things that lived in the lake and contributed to that organic-rich sludge.

My lab is investigating some of the earliest evidence of the evolution of life on Earth, and one technique is to examine very tiny fossils – and there are not that many of them. So my project is working towards being able to take an individual microfossil and analyze it with our instruments. Right now, the state-of-the-art method needs a sample with about 10 times as much carbon as these microfossils to work properly. There’s also a lot of possible contamination with that method. So I'm working on trying to get a different method to work.

How does this work play into NASA missions and science?

We're planning on eventually getting samples back to Earth sometime in the future after the Mars 2020 rover lands, and we want to be able to get the most information out of the tiniest amount of material so that more people can have the opportunity to experiment on it.

What are the samples that you’re working with?

The samples that I'm working with are these little blobs of organic, carbon-walled microfossils. We don't really know what they are. They're called acritarchs, which is basically a lump-all term for, “of uncertain origin,” but they're some of the oldest biological signatures on Earth.

What's an average day like for you?

Amanda Allen stands in the abcLab at JPL

I’ve been working with the same lab over the past 3 years. At first, I was trying to get a handle on imaging the samples, studying them with a light microscope and our scanning electron microscope, looking for things like whether the surfaces had any rock bits left on them, estimating how much carbon they had, and then preparing them to be analyzed.

This summer, the instrument I’m working with is this really cool device called a Pyroprobe. It has a little platinum wire coil, and you fit a tiny little sample tube into it and the platinum coil will heat up to around 1,500 degrees Celsius [about 2,700 degrees Fahrenheit]. We use oxygen to combust the sample so any carbon on it will turn into carbon dioxide. The carbon dioxide can get passed to our isotope ratio mass spectrometer.

How do you feel that you're contributing to NASA missions and science?

I think the people I work with have a really good vision and intention when going about investigations like this. We want to be the ones who they hand the samples to when they come back from Mars. We want to show that we're taking every necessary precaution to treat the samples with care and that we have instruments that can look at thin sections of rocks and make images of them that can be shared instantaneously. I really like being a part of that.

I also feel like my superpower is being able to find things. So if there's something cool to find on Mars related to astrobiology, I think I can help with that. Finding life or signs of life on Mars is the coolest application of my superpower [laughs].

Before taking the science route, you were involved in theater and costume design. What made you choose to study science?

I had a really hard time choosing between costuming and geology for a long time. But then I realized that they didn't have to be separate things, or I could use one to kind of fuel the other one, and use an understanding of the natural world to inspire my art. Being able to actualize new ways of understanding the universe and helping other people understand it is really important, and I think that's where art comes in.

What's the most JPL or NASA unique experience you've had so far?

I think it's just being able to start up a conversation in the lunch line with someone and hear about this whole other experience and the important work that they are doing. People here are excited about what they do and excited to come to work. They want to cross boundaries. It’s people’s job to be the intermediary between the engineering side of things and the science side of things, and I’m totally into that emphasis on communication and bridging traditionally divided disciplines.

If you could travel anywhere in space, where would you go and what would you do there?

Hiking around Pluto would be pretty cool. I never thought I would say that until I saw the images of Pluto from New Horizons. I also realized recently that I'm more interested in going to Mars than another place on Earth. I'm like, oh yeah, Prague is cool, but I'm just more interested in Mars.

In the News

A pair of Earth orbiters designed to keep track of the planet's water resources and evolving water cycle is scheduled to launch this month – no earlier than May 22, 2018. The Gravity Recovery and Climate Experiment Follow-On mission, or GRACE-FO, will pick up where its predecessor, GRACE, left off when it completed its 15-year mission in 2017. By measuring changes in Earth’s gravity, the mission will track water movement around the globe, identifying risks such as droughts and floods and revealing how land ice and sea level are evolving. The GRACE-FO mission is a great way to get students asking, and answering, questions about how we know what we know about some of the major components of Earth’s water cycle: ice sheets, glaciers, sea level, and ground-water resources.

How It Works

The GRACE-FO mission, a partnership between NASA and the German Research Centre for Geosciences (GFZ), will measure small variations in Earth’s mass to track how and where water is moving across the planet. This is no easy task, as water can be solid, liquid or gas; it can be in plain sight (as in a lake or glacier); it can be in the atmosphere or hidden underground; and it’s always on the move. But one thing all this water has in common, regardless of what state of matter it is in or where it is located, is mass.

Everything that has mass exerts a gravitational force. It is this gravitational force that GRACE-FO measures to track the whereabouts of water on Earth. Most of Earth's gravitational force, more than 99 percent, does not change from one month to the next because it is exerted by Earth’s solid surface and interior. GRACE-FO is sensitive enough to measure the tiny amount that does change – mostly as a result of the movement of water within the Earth system.

GRACE-FO works by flying two spacecraft in tandem around Earth – one spacecraft trailing the other at a distance of about 137 miles (220 kilometers). By pointing their microwave ranging instruments at each other, the satellites can measure tiny changes in the distance between them – within one micron (the diameter of a blood cell) – caused by changes in Earth’s gravitational field. Scientists can then use those measurements to create a map of Earth’s global gravitational field and calculate local mass variations.

As the forward spacecraft travels over a region that has more or less mass than the surrounding areas, such as a mountain or low valley, the gravitational attraction of that mass will cause the spacecraft to speed up or slow down, slightly increasing or decreasing the relative distance between it and its trailing companion. As a result of this effect, GRACE-FO will be able to track water as it moves into or out of a region, changing the region’s mass and, therefore, its gravity. In fact, the previous GRACE spacecraft measured a weakening gravity field over several years in Central California, enabling an estimate of aquifer depletion, and in Greenland, providing accurate measurements of ice melt over more than 15 years.

Why It’s Important

Tracking changes in our water resources and the water cycle is important for everyone. The water cycle is one of the fundamental processes on Earth that sustains life and shapes our planet, moving water between Earth's oceans, atmosphere and land. Over thousands of years, we have developed our civilizations around that cycle, placing cities and agriculture near rivers and the sea, building reservoirs and canals to bring water to where it is needed, and drilling wells to pump water from the ground. We depend on this cycle for the water resources that we need, and as those resources change, communities and livelihoods are affected. For example, too much water in an area causes dangerous floods that can destroy property, crops and infrastructure. Too little water causes shortages, which require us to reduce how much water we use. GRACE-FO will provide monthly data that will help us study those precious water resources.

Twenty-one aquifers have exceeded sustainability tipping points and are being depleted, and 13 of these are considered significantly distressed, threatening regional water security and resilience.

Changes to Earth’s water over multiple years are an important indicator of how Earth is responding in a changing climate. Monitoring changes in ice sheets and glaciers, surface and underground water storage, the amount of water in large lakes and rivers, as well as changes in sea level and ocean currents, provides a global view of how Earth’s water cycle and energy balance are evolving. As our climate changes and our local water resources shift, we need accurate observations and continuous measurements like those from GRACE and GRACE Follow-On to be able to respond and plan.

As a result of the GRACE mission, we have a much more accurate picture of how our global water resources are evolving in both the short and long term. GRACE-FO will continue the legacy of GRACE, yielding up-to-date water and surface mass information and allowing us to identify trends over the coming years.

Teacher Lina Khosrovian in her classroom

Ms. Khosrovian teaches third grade at Stonehurst Magnet Elementary in Los Angeles County.

Lina Khosrovian is a first-year teacher at Stonehurst Magnet Elementary, a STEAM magnet school in Los Angeles County. She teaches third-grade students subjects including language arts, math, science and social studies. Ms. Khosrovian recently reached out about how she added her own creative spin to the JPL lesson Art and the Cosmic Connection to have it reflect her multidisciplinary classroom.

What inspires you to teach?

I am in my first year of teaching, and I could not be more driven and excited to teach my students about all the wonders of life. I am a learner myself, and I strive to discover new and moving ways to instill knowledge upon my students.

I consider myself extremely lucky to be teaching at Stonehurst, where we have a passion for teaching STEAM to our students. I especially appreciate the students’ enthusiasm for learning science.

What challenges do you face engaging or addressing the needs of your students?

I have found that the key to effectively and successfully teaching students is to teach what they admire, are curious or fascinated about or have an appreciation for. I always ask my students about their interests and what they would like to learn. This inspires my lessons and tends to each students’ individual interest in learning.

How did you incorporate a JPL Education lesson into your classroom?

Art and the Cosmic Connection Lesson from NASA/JPL Edu

Art and the Cosmic Connection

In this lesson for grades K-12, students use art to describe and recognize the geology on planetary surfaces.

Brandon Rodriguez, an educator professional development specialist at NASA’s Jet Propulsion Laboratory, visited our school and presented a lesson called Art and the Cosmic Connection.

After showing us images of planets, Mr. Rodriguez handed out paper, chalk, crayons and markers, and instructed us to draw our own imaginary planet. Listening to his awe-inspiring lecture, I began to think about the beautiful garden at our school and wondered how I could incorporate it into a similar activity with my students. I decided that I would have my students create their own planet inspired by the school garden.

First, my students and I began to learn about different planets together, discussing the possible history of each unique world. We conversed and wrote about our theories. Then each student drew and wrote about their own, imaginary planet. Some students drew icy planets and said that the ice had melted when the planet was close to the Sun. Other students explained that the uniqueness of their planet was due to the presence of life and water.

With our knowledge, ideas and imagination, we grabbed paper bags to collect soil, sticks, hay, leaves, rocks and other natural items from the garden. Back in the classroom, each student began to construct 3-D versions of their drawings with the materials they collected. Their work was beautifully presented, with soil representing land, leaves representing life, blue paint representing water, and mixtures representing unknown and unique creations – plus some silver paint to make it all more “cosmic.”

How did it help you meet your objectives? How did students react to the lesson?

This lesson allowed my students to engage with the world around them and understand that planets have a uniqueness and a history that is quite remarkable. The lesson gave students a chance to discover more about their own planet and express their connection to it.

I sincerely value the JPL Education lessons, activities and resources, as they are quite beneficial to teachers. Each activity and lesson provides the opportunity for students to learn and wonder. And when you’re inspired to wonder, the possibilities are endless – and so is the fun!

Students plot changes in Earth's gravitational field using data from NASA's GRACE mission.

LoriAnn Pawlik recently shared her NASA-inspired lesson during a professional development workshop hosted by the agency. LoriAnn teaches STEM to grades K-5 at Penn Elementary School in Prince William County, Virginia, which focuses on students learning English, as well as those with learning disorders and autism. When she recently came across a lesson on the NASA/JPL Edu website, she saw an opportunity to bring real-world NASA data to her students.

How do you use NASA in the classroom?

Using the lesson “How to Read a Heat Map” as a jumping-off point, LoriAnn had her students first dive into the practice of reading and interpreting graphs. From here, she extended the lesson with an exploration of NASA satellites and the data they collect, focusing on the Gravity Recovery And Climate Experiment, or GRACE mission, to tie in with a community science night on water science.

GRACE was launched in 2002 to track changes in the distribution of liquid water, ice and land masses on Earth by measuring changes in the planet’s gravity field every 30 days. Circling Earth 16 times each day, GRACE spent more than 15 years collecting data – all of which is available online – before its science mission ended last October. The mission provided students the perfect context to study climate and water through authentic NASA data.

LoriAnn's students plotted changes in Earth's gravitational field using data from NASA's GRACE mission.

How did students react to the lesson?

LoriAnn set the stage for her students by explaining to them that they would be providing their data to NASA scientists.

“I told them that I was working on a project for a scientist from NASA-JPL and that we needed their help,” she said via email. “By the time I gave them the background and showed a brief GRACE video, they were all in – excited, eager enthusiastic! It helped that each table, or ‘engineering group,’ was responsible for a different U.S. state.”

As a result, students were able to plot the changes in gravitational fields for multiple locations over several years.

What are other ways you use NASA lessons or resources?

By extending the lesson, LoriAnn gave her students a sense of authentic ownership of the data and practice in real scientific analysis. But it wasn’t her first time uniting NASA science with her school curriculum:

“I'd been working with our second-graders on field studies of habitats,” LoriAnn explained. “We observed, journaled and tracked the migration of monarch butterflies, discussed what happened to habitats of living things since Hurricane Harvey and Hurricane Irma were just going through, and then I used the [NASA Mars Exploration website] to have students extend the findings to space habitats.”
