Find out how the now famous video beamed from space, showing a cat chasing a laser, marked a milestone for space exploration, and find resources to engage students in related STEM learning.


You may have seen in the news last month that NASA beamed a cat video from space. It was all part of a test of new technology known as Deep Space Optical Communications. While the video went down in cat video history, the NASA technology used to transmit the first ultra-high-definition video from deep space also represented a historic advancement for space exploration – the potential to stream videos from the Moon, Mars, and beyond.

Read on to learn how this new technology will revolutionize space communications. Then, explore STEM learning resources that will get students using coding, math, and engineering to explore more about how NASA communicates with spacecraft.

Why did NASA beam a cat video from space?

Communicating with spacecraft across the solar system means sending data – such as commands, images, measurements, and status reports – over enormous distances, with travel times limited by the speed of light. NASA spacecraft have traditionally used radio signals to transmit information to Earth via the Deep Space Network, or DSN. The DSN is made up of an array of giant antennas situated around the globe (in California, Spain, and Australia) that allow us to keep in contact with distant spacecraft as Earth rotates.

When scientists and engineers want to send commands to a spacecraft in deep space, they turn to the Deep Space Network, NASA’s international array of giant antennas. | Watch on YouTube

Although sending transmissions using radio frequencies works well, advances in spacecraft technology mean we're collecting and transmitting a lot more data than in the past. The more data a spacecraft collects and needs to transmit to Earth, the more time it takes to transmit that data. And with so many spacecraft waiting to take their turn transmitting via the DSN's antennas, a sort of data traffic jam is on the horizon.

To alleviate the potential traffic jam, NASA is testing technology known as optical communications, which allows spacecraft to send and receive data at a higher information rate so that each transmission takes less of the DSN’s time.

The technology benefits scientists and engineers – or anyone who is fascinated by space – by allowing robotic spacecraft exploring planets we can't yet visit in person to send high-definition imagery and stream video to Earth for further study. Optical communications could also play an important role in upcoming human missions to the Moon and eventually to Mars, which will require a lot of data transmission, including video communication.

But why transmit a video of a cat? For a test of this kind, engineers would normally send randomly generated test data. But, in this case, to mark what was a significant event for the project, the team at NASA's Jet Propulsion Laboratory worked with the center's DesignLab to create a fun video featuring the pet of a JPL employee – a now famous orange tabby named Taters – chasing a laser. The video was also a nod to the project's use of lasers (more on that in a minute) and the first television test broadcast in 1928 that featured a statue of the cartoon character Felix the Cat.

This 15-second ultra-high-definition video featuring a cat named Taters was streamed via laser from deep space by NASA on Dec. 11, 2023. | Watch on YouTube

How lasers improve spacecraft communications

The NASA project designed to test this new technology is known as Deep Space Optical Communications, or DSOC. It aims to prove that we can indeed transmit data from deep space at a higher information rate.

To improve upon the rate at which data flows between spacecraft and antennas on Earth, DSOC uses laser signals rather than the radio signals currently used to transmit data. Radio signals and laser signals are both part of the electromagnetic spectrum and travel at the same speed – the speed of light – but they have different wavelengths. The DSOC lasers transmit data in the near-infrared portion of the electromagnetic spectrum, so their wavelength is shorter than radio waves, and they have a higher frequency.

Each type of wave on the electromagnetic spectrum is represented with a wavy line. Each wave – radio, microwave, infrared, visible, ultraviolet, x-ray, and gamma ray – is between a range of wavelengths that get shorter (from >100,000,000 nm to <.01 nm) and frequencies that get higher (from <3x10^9 to >3x10^19 Hz) from left to right. Visible light makes up a relatively tiny portion of the full spectrum.

This chart compares the wavelength and frequency range of each kind of wave on the electromagnetic spectrum. Note: The graphic representations are not to scale. Image credit: NASA/JPL-Caltech | + Expand image | › Download low-ink version for printing

Since there are more infrared than radio wavelengths over a particular distance, more data can be sent over the same distance using infrared. And since the speed of infrared and radio waves is equal to the speed of light, this also means that more data can be sent in the same length of time using infrared.

As a result, DSOC’s maximum information rate is around 267 megabits per second (Mbps), faster than many terrestrial internet signals. At that high data rate, the 153.6 megabit cat video took only 0.58 seconds to transmit and another 101 seconds to travel the 19 million miles to Earth at the speed of light. Instead, if we had sent the cat video using Psyche's radio transmitter, which has a data rate of 360 kilobits per second, it would have taken 426 seconds to transmit the video, plus the same speed-of-light travel time, to get to Earth.

Here's how DSOC aims to revolutionize deep space communications. | Watch on YouTube

This kind of spacecraft communications isn't without its challenges. Accurately pointing the narrow laser beam is one of the greatest challenges of optical communications.

DSOC consists of a "flight laser transceiver" aboard the Psyche spacecraft – which is currently on its journey to study the asteroid 16-Psyche – and a receiving station on Earth. The flight transceiver is a 22-centimeter-diameter apparatus that can both transmit and receive signals. Its maximum transmitter strength is a low 4 Watts. For the December 2023 test, a 160-Watt beacon signal was transmitted to the DSOC flight transceiver by a 1-meter telescope located at JPL's Table Mountain facility near Wrightwood, California. This beacon signal was used by the Psyche spacecraft as a pointing reference so it could accurately aim the DSOC transceiver at the Earth receiving station – the 5-meter Hale telescope at Caltech’s Palomar Observatory near San Diego.

This animation shows how DSOC's laser signals are sent between the Psyche spacecraft and ground stations on Earth - first as a pointing reference to ensure accurate aiming of the narrow laser signal and then as a data transmission to the receiving station. | Watch on YouTube

When the DSOC laser beam encounters Earth, it is much narrower than a radio signal transmitted from the same distance. In fact, the laser beam is only a few hundred kilometers wide when it reaches Earth, in sharp contrast with an approximately 2.5-million-kilometer-wide radio signal. This narrow beam must be pointed accurately enough so it not only intersects Earth, but also overlaps the receiving station. To ensure that the beam will be received at Palomar Observatory, the transmission must be aimed not directly at Earth, but at a point where Earth will be in its orbit when the signal arrives after traveling the great distance from the spacecraft.

What's next for laser communications

Engineers will do additional tests of the DSOC system as the Psyche spacecraft continues its 2.2-billion-mile (3.6-billion-kilometer) journey to its destination in the asteroid belt beyond Mars. Over the next couple of years, DSOC will make weekly contacts with Earth. Visit NASA's DSOC website to follow along as NASA puts the system through its paces to potentially usher in a new means of transmitting data through space.

How does the cat video relate to STEM learning?

The DSOC project provides a wonderful opportunity to help students understand the electromagnetic spectrum and learn about real-world applications of STEM in deep space communications. Try out these lessons and resources to get students engaged.

Spikes of light extend from the Sun shining above the glowing blue limb of Earth, as shown from space.

Leap day, Feb. 29, happens every four years because of a mismatch between the calendar year and Earth's orbit. Learn how it works, and get students engaged in leap day STEM.


You may have noticed that there's an extra day on your calendar this year. That's not a typo – it's leap day! Leap day is another name for Feb. 29, a date that typically comes around every four years, during a leap year.

Why doesn't Feb. 29 appear on the calendar every year?

The length of a year is based on how long it takes a planet to revolve around the Sun. Earth takes about 365.2422 days to make one revolution around the Sun. That's about six hours longer than the 365 days that we typically include in a calendar year. As a result, every four years, we have about 24 extra hours that we add to the calendar at the end of February in the form of leap day.

Without leap day, the dates of annual events, such as equinoxes and solstices, would slowly shift to later in the year, changing the dates of each season. After only a century without leap day, summer wouldn’t start until mid-July!

But the peculiar adjustments don't end there. If Earth revolved around the Sun in exactly 365 days and six hours, this system of adding a leap day every four years would need no exceptions. However, Earth takes a little less time than that to orbit the Sun. Rounding up and inserting a 24-hour leap day every four years adds about 45 extra minutes to every four-year leap cycle. That adds up to about three days every 400 years. To correct for that, years that are divisible by 100 don't have leap days unless they’re also divisible by 400.

If you do the math, you'll see that the year 2000 was a leap year, but 2100, 2200 and 2300 will not be.

Have students learn more about leap years with this article from NASA's Space Place, then have them do the math for themselves with this leap day problem set. You can also have students write a letter or poem to be opened on the next leap day or get them learning about orbits across the solar system.

And since we've got an extra 24 hours this year, don't forget to take a little time to relax!

October

October 12 – Join NASA for the Psyche Launch

Did you know we can explore asteroids and other far away objects in the solar system to learn more about the interior of our own planet? That's one of the goals of NASA's Psyche mission, which is slated to launch on October 12 from NASA's Kennedy Space Center in Florida. The mission is designed to explore an asteroid – also named Psyche – that may be the remnant of a planet's core.

The Psyche spacecraft is one of just a handful of NASA missions throughout history that have used electric propulsion rather than a chemical engine, which means it's also a great opportunity to make connections to real-world examples of motion and forces. Get a primer on all the engineering and science behind the mission from our Teachable Moments series, then explore related lessons and projects.

October 14 – Catch the Annular Solar Eclipse

October 14 marks the start of another exciting double-feature for skygazers: an annular solar eclipse followed by a total solar eclipse just six months later. In both events, the Sun, Moon, and Earth will align, creating a spectacular sight in the sky. But during the annular solar eclipse on October 14, a ring of sunlight will remain visible around the Moon. This is due to differences in the relative distances between the Sun, Moon, and Earth during the eclipse. In any case, remember to never look directly at the Sun without proper protection, such as certified solar eclipse glasses.

Another fun way to view a solar eclipse is by making a pinhole camera. Students can even use their pinhole cameras to make solar art. Check out our Teachable Moments article for more info on where and when to watch the eclipse, plus a primer on the science of solar eclipses. And explore even more eclipse lessons and activities – including a math puzzler from our NASA Pi Day Challenge.

A cube-shaped spacecraft with two long wing-like solar arrays in the shape of crosses flies toward a large asteroid that appears to have patches of rocky and metal material on its surface

Explore how NASA's Psyche mission aims to help scientists answer questions about Earth and the formation of our solar system. Then, make connections to STEM learning in the classroom.


NASA is launching a spacecraft in October 2023 to visit the asteroid Psyche, a metal-rich asteroid. The mission with the same name, Psyche, will study the asteroid, which is located in the main asteroid belt between Mars and Jupiter, to learn more about our solar system, including the core of our own planet.

Read more to find out what we will learn from the Psyche mission. Get to know the science behind the mission and follow along in the classroom using STEM teaching and learning resources from NASA.

Why It's Important

The dark rocky and metallic Psyche asteroid appears covered with large and small craters in this illustration. Some of the craters have a lighter brown material in them. The asteroid is illuminated from the upper left.

Asteroids are thought to be rocky remnants that were left over from the early formation of our solar system about 4.6 billion years ago. Of the more than 1.3 million known asteroids in our solar system, Psyche’s metallic composition makes it unique to study. Ground-based observations indicate that Psyche is a giant metal-rich asteroid about one-sixteenth the diameter of Earth’s Moon and shaped like a potato. Scientists believe it might be the partial nickel-iron core of a shattered planetesimal – a small world the size of a city that is the first building block of a planet. Asteroid Psyche could offer scientists a close look at the deep interiors of planets like Earth, Mercury, Venus, and Mars, which are hidden beneath layers of mantle and crust.

We can’t see or measure Earth’s core directly – it is more than 1,800 miles (3,000 kilometers) below the surface and we have only been able to drill about 7.5 miles (12 kilometers) deep with current technology. The pressure at Earth’s core measures about three million times the pressure of the atmosphere at the surface, and the temperature of Earth’s core is about 9,000 degrees Fahrenheit (5,000 degrees Celsius), so even if we could get science instruments there, the hostile conditions would make operations practically impossible. The Psyche asteroid may provide information that will allow us to better understand Earth’s core, including its composition and how it was created. The asteroid is the only known place in our solar system where scientists might be able to examine the metal from the core of a planetesimal.

The Psyche mission's science goals are to understand a previously unexplored building block of planet formation (iron cores); to explore a new type of world; and to look inside terrestrial planets, including Earth, by directly examining the interior of one of these planetary building blocks, which otherwise could not be seen. The science objectives that will help scientists meet these goals include determining if asteroid Psyche is actually leftover core material, measuring its composition, and understanding the relative age of Psyche's surface regions. The mission will also study whether small metal-rich bodies include the same light elements that are hypothesized to exist in Earth's core, determine if Psyche was formed under similar or different conditions than Earth's core, and characterize Psyche's surface features.

How It Will Work

The Psyche mission will launch on a SpaceX Falcon Heavy rocket. Psyche’s solar arrays are designed to work in low-light conditions because the spacecraft will be operating hundreds of millions of miles from the Sun. The twin plus-sign shaped arrays will deploy and latch into place about an hour after launch from Earth in a process that will take seven minutes for each wing. With the arrays fully deployed, the spacecraft will be about the size of a singles tennis court. The spacecraft’s distance from the Sun will determine the amount of power it can generate. At Earth, the arrays will be able to generate 21 kilowatts, which is enough electricity to power three average U.S. homes. While at asteroid Psyche, the arrays will produce about two kilowatts, which is a little more than what is needed to power a hair dryer.

The spacecraft will rely on the launch vehicle’s large chemical rocket engines to blast off the launchpad and escape Earth’s gravity, but once in space, the Psyche spacecraft will travel using solar-electric propulsion. Solar-electric propulsion uses electricity from the solar arrays to power the spacecraft’s journey to asteroid Psyche. For fuel, Psyche will carry tanks full of xenon, the same neutral gas used in car headlights and plasma TVs. The spacecraft’s four thrusters – only one of which will be on at any time – will use electromagnetic fields to accelerate and expel charged atoms, or ions, of that xenon. As those ions are expelled, they will create thrust that gently propels Psyche through space, emitting blue beams of ionized xenon. The thrust will be so gentle that it will exert about the same amount of pressure you’d feel holding three quarters in your hand, but it’s enough to accelerate Psyche through deep space. You can read more about ion propulsion in this Teachable Moment.

The spacecraft, which will travel 2.2 billion miles (3.6 billion kilometers) over nearly 6 years to reach its destination, will also use the gravity of Mars to increase its speed and to set its trajectory, or path, to intersect with asteroid Psyche’s orbit around the Sun. It will do this by entering and leaving the gravitational field of Mars, stealing just a little bit of kinetic energy from Mars’ orbital motion and adding it to its own. This slingshot move will save propellant, time, and expense by providing a trajectory change and speed boost without using any of the spacecraft’s onboard fuel.

Upon arrival at Psyche, the spacecraft will spend 26 months making observations and collecting data as it orbits the asteroid at different altitudes. Unlike many objects in the solar system that rotate like a spinning top, the asteroid Psyche rotates on its side, like a wheel. Mission planning teams had to take this unique characteristic into account in planning the spacecraft's orbits. The different orbits will provide scientists with ideal lighting for the spacecraft's cameras and they will enable the mission to observe the asteroid using different scientific instruments onboard.

The spacecraft will map and study Psyche using a multispectral imager, a gamma-ray and neutron spectrometer, a magnetometer, and a radio instrument (for gravity measurement). During its cruise to the asteroid, the spacecraft will also test a new laser communication technology called Deep Space Optical Communication, which encodes data in photons at near-infrared wavelengths instead of radio waves. Using light instead of radio allows the spacecraft to send more data back and forth at a faster rate.

September

Rendezvous with an Asteroid

A distant asteroid system 6.8 million miles (11 million kilometers) from Earth was the site of NASA's first attempt at redirecting an asteroid. On September 26, the Double Asteroid Redirection Test, or DART, mission impacted the asteroid Dimorphos in an attempt to alter its speed and path around a larger asteroid known as Didymos. Dimorphos and Didymos do not pose a threat to Earth, which makes them a good proving ground for testing whether a similar technique could be used to defend Earth against potential impacts by hazardous asteroids in the future.

Get a primer on the DART mission and find related resources for the classroom in this article from our Teachable Moments series. Plus, explore our collection of standards-aligned lessons and activities all about asteroids to get students learning about different kinds of space rocks, geology, and meteoroid math.

A Closer Look at Europa

Just a few days later, on September 29, the Juno spacecraft that had been orbiting Jupiter since 2016 captured the closest views of Jupiter’s moon Europa in more than 20 years. The ice-covered moon is thought to contain a subsurface liquid-water ocean, making it an exciting new frontier in our search for life beyond Earth. NASA's Europa Clipper mission, which is scheduled to launch in 2024 is designed to study the moon in more detail. But until Europa Clipper arrives at the Jovian system in 2030, these observations from Juno are our best chance to get a closer look at this fascinating moon.

October

Celebrate Halloween Like a Space Explorer

The month of October is the perfect time to get students exploring our STEM activities with a Halloween twist. Students can learn how to carve a pumpkin like a JPL engineer, take a tour of mysterious locations throughout the solar system, and dig into the geology inside their Halloween candy.

October 31 is also JPL's 86th birthday, which makes October a great time to learn more about JPL history, including the team of female mathematicians known as "human computers" who performed some of the earliest spacecraft-tracking calculations and the Laboratory's role in launching the first U.S. space satellite.

To gain an edge in one of the world's premier robotics competitions, JPL brought in a team of experts at the forefront of their field – college students. The experience gave the interns and the Laboratory a new perspective on what's possible.


You know that movie trope where a talented mastermind recruits a ragtag team of experts to pull off a seemingly impossible task. That's what I imagine when Ali Agha talks about the more than 30 interns brought to NASA's Jet Propulsion Laboratory to take part in one of the world's premier robotics competitions.

In 2018, a group led by Agha was one of only 12 teams chosen worldwide to compete in the Defense Advanced Research Projects Agency, or DARPA, Subterranean Challenge, a three-year-long competition that concluded this past September and brought together some of the brightest minds in robotics. Their goal was to develop robotic systems for underground rescue missions, or as Agha puts it, "solutions that are so state-of-the-art, there's not even a clear definition of what you're creating."

Calling themselves Team CoSTAR, which stands for Collaborative SubTerranean Autonomous Resilient Robots, the group also included engineers from Caltech, Massachusetts Institute of Technology, Korea Advanced Institute of Science and Technology, Sweden’s Lulea University of Technology, and several industry partners.

Interns from across the country and around the world came to JPL to help conceive of, build, and test CoSTAR – a coordinated rescue team of flying, crawling, and rolling robots designed to operate autonomously, or with little to no help from humans. But the interns didn't just come to the laboratory to learn from engineers already well versed in building robots to explore extreme environments. In many cases, the interns were the experts.

"The problem we needed to solve, nobody knew how to solve it, so we needed people who are at the cutting edge of these technologies," says Agha. "We needed to get that one person in the world or a few people in the world who work on that specific camera or sensor or data or specific algorithm to come and educate us."

And Agha knew exactly where to find them: colleges and universities.

The interns' contributions would end up reaching far beyond the challenge. And the entire experience – from the mentorship they received to the technology they developed to the friendships they built – would change the course of their careers.

The Visionary

Even the Perseverance Mars rover, the latest and greatest Red Planet explorer designed and built at JPL, requires a fair amount of direction from mission controllers back on Earth to navigate around hazards and know which rocks to zap with its laser or when to phone home.

Since coming to JPL in 2016, Agha had been researching ways to make planet-exploring robots more autonomous so they could make similar decisions on their own. He was especially interested in autonomous technology for underground environments like caves and volcanoes, where the terrain and visibility make remote guidance challenging.

So when DARPA announced that it was launching a competition aimed at the development of autonomous robots for subterranean rescue missions, Agha jumped at the opportunity.

Agha stands in front of a large projector screen with robots of various shapes and sizes lined up against the wall behind him.

"It was a very good alignment and a great opportunity for JPL and for NASA," says Agha. "We knew if we can get into this program, it's going to expedite the technology development at a really high pace, and that's going to help NASA and JPL to develop these capabilities [for our own projects]."

But like developing robots for space exploration, the requirements would be tough.

Teams would need to build a robotic system that could autonomously navigate four circuits – a tunnel, an urban underground, a cave, and a combination of the three – in search of scientific "artifacts," or signs of human activity, hidden throughout the course. Then, in just 60 minutes, the robots would need to make their way through winding, cavernous, and dangerous terrain to correctly report the locations of as many artifacts as possible.

There were just 12 months between when proposals were selected and the first event in August 2019. Agha needed a plan – and a team.

The Strategist

Sung Kim first came to JPL as an intern in 2017, a year before the DARPA Subterranean Challenge was announced. A Carnegie Mellon doctoral student researching ways to help robots plan under uncertainty, Kim's childhood dream to work for NASA was rekindled when he saw an internship posting with Agha's team.

"From the first meeting, there was a spark," says Kim of his interview with Agha. "At the time, there were not many people actively pursuing that area [of planning under uncertainty]."

Kim spent that summer at JPL helping the team begin to develop what would later become the backbone of CoSTAR – a system in which robots can analyze their surroundings to find a route that covers as much ground as possible, increasing the odds that they will make discoveries along the way.

For JPL's part, such technology could be key to designing robots to explore worlds like Jupiter's moon Europa, where the terrain is still relatively unknown. For CoSTAR, it would improve the team's chances of finding artifacts hidden throughout the challenge course, earning the team points toward a victory.

When JPL's DARPA proposal was selected a year later, Agha eagerly enticed the newly graduated Kim back to the laboratory, this time as an employee and the head of CoSTAR's Global Planning Team tasked with "maximizing the chances of finding artifacts hidden in the environment," says Kim.

Kim would be the first of a wave of students who would come to the laboratory over the next several years to lend their expertise in making CoSTAR a reality. In fact, one of them had already arrived.

The Detective

Xianmei "Sammi" Lei was looking to start over. She had come to the U.S. from China and become a legal permanent resident in hopes of finding better career opportunities. But she worried that her options would be limited while she was still making professional connections and learning English. That's when she discovered community college.

"One of the turning points for me here was realizing that we have something called community college," says Lei. "That gave me a lot of opportunities."

It was at Pasadena Community College that Lei started to build a network of peers and professionals and began her foray into the world of robotics. It was also where her passion for computer science was reignited, setting her on a trajectory to JPL and Agha's team.

"I took the beginning level of C++, and I liked it so, so much," says Lei. "I was like, 'Oh my god, you can realize your dreams through programming. That is so powerful!'"

Lei wears a Team CoSTAR shirt and crouches in front of sign that reads DARPA Subterranean Challenge Urban Circuit - To Beta Course.

Lei applied for an internship at JPL through the Student Independent Research Intern, or SIRI, program, which is designed to pair students from local community colleges with researchers at the laboratory. She caught Agha's eye thanks to her involvement in a swarm robotics competition. Still relatively new to the field, Lei spent her first internship in 2017 soaking it all in, learning as much as she could, reading papers assigned by Agha, and following him to meetings, she says.

At the encouragement of her growing network, Lei applied and was accepted to a master's program at Cal Poly Pomona. She went on to spend four more years at JPL throughout her graduate degree and the entire DARPA challenge. All the while, she played an integral role on CoSTAR as the person in charge of programming the system to detect the most coveted artifact of all.

"Inside the environment was a dummy that was simulating a human survivor with the same weight, same heat, wearing a safety vest, things like that," says Lei. "My job was to detect those signals with the robot and have it report back to the team so the human supervisor could verify."

But before that could happen, the system would need to overcome any number of hazards, which according to DARPA might include small passages, sharp turns, stairs, rails, large drops, mud, sand, water, mist, smoke, dead ends, slippery terrain, communications constraints, moving walls, and falling debris. The team needed a mobility expert.

The Navigator

"I was doing lots of mathy stuff," says David Fan of his doctoral research at Georgia Tech prior to coming to JPL in the fall of 2018.

Fan had been researching algorithms that could help robots learn to independently navigate complex terrain when his advisor told him about an internship opening on Agha's team with the JPL Visiting Student Researchers Program, or JVSRP. Fan saw it as a chance to take his work out of the theoretical and into the real world.

"Once I joined the team and started working on these robots in real life, it opened up a whole set of new problems that I had never thought about before," he says.

Fan stands with his arms crossed in front of a fake rock wall and spotlights framing a rocky tunnel.

Problem one: How to get a robot through a hazard-filled course that requires a system with an almost contradictory set of features – small enough to get through narrow passages but big enough to support computing power, nimble enough to climb stairs and cross slippery terrain but strong enough to withstand falling debris.

Fan spent his early days with the team dreaming up robots with different kinds of locomotion – wheels, tracks, rotors, legs, and so on. Eventually, the team homed in on a solution involving all of the above, multiple robots with unique talents and ways of moving. Fan's doctoral research was key to unlocking how each robot could continually improve their skills, learning to navigate around obstacles as they encountered them.

"Each environment would have its own set of challenges," says Fan, who interned with Agha throughout the DARPA challenge. "Trying to figure out where the robots could safely go in a subway was very different than where they could safely go in a cave or a mine. We broke a lot of robots. It was really fun."

But as often happens in engineering, one solution begets another problem. In this case it was how to coordinate multiple robots and get them working as a team.

The Field Commander

As a child in Indonesia, Muhammad Fadhil Ginting's favorite movie was a documentary about NASA rocket technology built to send astronauts to the Moon. He would watch it and rewatch it, dreaming of one day working at the space agency. But even after he had grown up to earn his bachelor's in engineering and begin to pursue his master's in robotics at one of the world's top universities, ETH Zurich, working for NASA seemed like a distant childhood dream.

That is until he saw an internship opening with Agha's team.

"Back in my undergrad in Indonesia, I was working with underwater robots to explore the ocean. When I found out JPL offered internships with the DARPA challenge team and it was about subsurface explorations, I was so excited," says Ginting who, like Fan, applied through JVSRP, which also brings in a small number of interns from foreign universities to work with JPL researchers. "I met Dr. Agha at an international conference and expressed my interest in joining his team. It was a thrill when he accepted me and welcomed me to the team."

When Ginting came on board, CoSTAR had just placed second in the Tunnel Circuit, the first of the four events.

After helping develop a strategy to coordinate the robots, Ginting was chosen for the team's exclusive "pit crew" along with just four others: Fan, also an intern at the time, and JPL employees Kyon Otsu, Ben Morrell, and Jeffrey Edlund.

On the pit crew, Ginting would have just 30 minutes to set up and release the robots into the subterranean course before he and the others were sequestered in a separate support area from Otsu, the sole robot supervisor. "It meant that I needed to be ready not just for the technical but also operational, anticipating all possible things that can happen in the field."

To prepare both the robots and the pit crew for handling the challenges ahead, the team took multiple field trips around California and to a limestone mine in Kentucky. When that wasn't possible, they sent the robots through cubicle mazes at JPL.

Ginting fondly remembers the field trips not just for the opportunity to work out any bugs in the software, but also for the chance to pursue his other passion for outreach, giving talks to college students and kids and chatting up locals at the hotel breakfast bar.

"I liked meeting the community and sharing the excitement of building robots, the excitement of space exploration," says Ginting, who also saw the field trips as a chance to bond with his teammates.

When the Urban Circuit came around in February 2020, the team with Ginting's help earned a first-place spot. And then, COVID hit.

An Unexpected Challenge

Like it did with so much else, the pandemic threw the team and the competition for a loop.

Interns were sent home along with most of the rest of JPL's more than 6,000 employees, and the CoSTAR team had to learn how to do their work remotely. Lei recalls testing sensors from her home in Los Angeles or asking other team members to try them out in different environments.

In some ways, the remote work was good for the team. Rather than the intensive testing schedule, "people had more time for thinking," says Lei. Meanwhile, the team was able to bring on remote interns previously unable to travel to the Southern California laboratory.

The Cave Circuit, originally scheduled for November 2020, was canceled, but once vaccines began rolling out and restrictions on indoor gatherings were loosened, DARPA announced that the Final Event would take place in September 2021.

The Light at the End of the Tunnel

"We were in pretty good shape – even in the preliminary rounds, we won with a good margin," says Agha. "But in the final event, our calibration system had an issue, so our robots entered the course 30 minutes late. It wasn't the kind of demonstration we were hoping to be able to have, but for that half of the time, it went really perfect."

While CoSTAR did not win the final competition, the overall experience was an unequivocal win not just for the team, but also for the interns and for JPL.

"We got all this great talent and technology – again, huge thanks to our interns and their mentors," says Agha. "They brought all this expertise to JPL, and the amount of capabilities that got developed really changed a lot about [autonomous technology] at JPL. We pushed state-of-the-art boundaries forward. We published strong papers and showed the world JPL's capabilities."

Already, the team's technology is making its way into a number of JPL and NASA projects including a snake-like robot designed to explore deep crevasses on icy worlds beyond Earth, self-driving offroad cars that could inspire future lunar exploration vehicles, and a project researching the possibility of finding microbial life within volcanic caves on Mars.

Many of the interns say the experience changed the course of their careers.

"It really set me on a different trajectory that I hadn't imagined before," says Fan, who is now working for the U.S. Navy in collaboration with JPL on the project to develop offroad self-driving vehicles. "It introduced me to so many of the real-world robotics problems that are out there waiting to be solved. It opened up a lot of doors and introduced me to a lot of people. It completely changed the trajectory of my Ph.D. and my career."

Lei was recently hired at JPL as a full-time employee, and she says she's looking forward to exploring new ways robots can assist humans in the future.

Kim continues to expand his research in new ways, taking part in JPL projects like Europa Lander, which hopes to send the first robot to explore the icy moon considered to be the next frontier in the search for life beyond Earth.

Ginting was accepted into a doctoral program at Stanford and is continuing his research collaboration with Agha and Kim. He says, "Now, I'm so eager to work on robotics research topics that can also work for space exploration."

In July, the entire team of about 150 people plans to meet up for a reunion cake party. Over the course of the challenge, cake parties had become an annual tradition for the tight knit group. They even managed to hold a virtual party in 2020. As with all things CoSTAR, the bakers go above and beyond to make cakes with life-like caves, moving parts, and LEDs.

When we talked, Agha flipped through photos of cake parties past and said that more than anything, it's this – the team camaraderie, the friendships – that is the greatest win of all.

We went behind the scenes with three interns on NASA’s Earth System Observatory team to learn how they're devoting their future careers to putting our planet first.


Leave it to the interns at NASA's Jet Propulsion Laboratory to school the full-timers. Case in point: JPL intern Joalda Morancy knows exactly how to explain—in bite-sized, plain English—NASA’s latest multi-missioned initiative to study our home planet.

“The Earth System Observatory aims to tackle one of the biggest issues we’re facing today—climate change,” they say of NASA's ESO. “We need to have multiple missions that look at the Earth system as a whole in order to tackle the issue of climate change in the next couple of decades.”

The observatory will be made up of an array of satellites, instruments, and missions to form a well-rounded collection of observations meant to offer crucial and precise measurements of our environment. As NASA puts it: “Taken together, as a single observatory, we will have a holistic, 3-dimensional understanding of our Earth’s systems—how they work together, how one change can influence another.”

While the ESO is in its early stages, it’s a crucial time for interns to be involved, as their generation will most likely face the most pressing challenges resulting from climate change. We spoke to three JPL interns getting first-hand experience with the observatory's missions and projects to learn why, to them, Earth is the most important planet to study right now.

Joalda Morancy

Morancy first became fascinated by space exploration in high school thanks to a YouTube video on how to make a peanut butter and honey sandwich in space.

“I love telling that story,” Morancy says with a laugh. “It was so random, and I was so intrigued. I watched the entire video and thought, ‘This is amazing.’ I did a lot more research about what NASA does and that was my gateway to space.”

Flash forward a few years to college at the University of Chicago, where Morancy discovered there was one planet in particular that really captured their attention: Earth.

“I was initially interested in space exploration, and while [majoring in] astrophysics, I took a class on what makes a planet habitable,” they recall. “It taught me everything about basic Earth sciences and how that ties into Earth and the big picture of how a habitable environment operates.”

Morancy found it so interesting and—combined with their growing alarm about climate change—wanted a hand in studying how to preserve our planet. So Morancy took more classes in geophysics and geophysical sciences, including courses on atmosphere, glaciology, and physical geology.

“I wanted to give myself the foundational knowledge,” Morancy says. “And right after that, I started at JPL.”

They had originally searched JPL’s careers site for internships with the Perseverance Mars rover mission but noticed an opening with the Earth Science team.

“I didn’t know JPL did Earth science; I thought it was mostly Mars and robotic exploration,” they say. “When I saw that opening, I knew it was the perfect opportunity for me to learn more about Earth.”

For the past year-and-a-half, Morancy has worked on ECOSTRESS, an ESO-related experiment aboard the International Space Station designed to measure water stress among plants. Now, they are interning with the ESO successor to ECOSTRESS, the Surface Biology and Geology, or SBG, mission.

“I help with a lot of project management since SBG is in its early stages,” they say. “A lot of things are starting to cook up, and a lot of engineers and scientists are being onboarded to the team. I’m working with the team to help onboard, and I’m also helping with the science instruments for SBG.”

The magnitude of being part of SBG and the observatory team in their early stages is not lost on Morancy.

“I really believe it will have a long-lasting impact on how we look at climate change and how we target those specific issues to fix,” they say. “It'll be a major driver for future researchers and scientists.”

While Morancy hopes to combine Earth sciences and space exploration for their future career, they’re invested in studying our blue planet for the long run.

“I think Earth science is incredibly important because this is our only home,” they say. “Even though people are looking to settle on Mars and other celestial bodies ... I think it’s important to take care of this rock we’ve been given to live on. It’s crucial to make sure we take care of it for future generations.”

Rebecca Gustine

When Rebecca Gustine studied abroad in Thailand during her junior year of college, she didn’t realize it would alter the course of her studies and her future career path.

“I had a lightbulb moment realizing how human development and access to water go hand in hand,” she says.

Gustine went on to Washington State University, where she is now a Ph.D. student studying civil engineering with a focus on water resources engineering.

“A lot of my undergraduate research had to do with water,” she explains. “It was from a global health perspective and had to do with access to clean water, hygiene, and gender dynamics in developing countries. I also really like math and physics, so combining global health with water resources engineering was very interesting.”

Gustine was so fascinated by water research, she knew she wanted to find an internship that would let her focus on just that. When she saw an open call for internships at JPL, she submitted her resume and was contacted by Gregory Halverson and Christine Lee, JPL scientists focused on using remote sensing measurements to study water quality, water resources, and ecosystems management.

Gustine started at JPL as an intern in August 2020, supporting the Earth science team by looking at how ECOSTRESS data could be used to preserve habitats in the California Bay Delta system, where the Sacramento and the San Joaquin Rivers meet. For the past year, she has focused on processing remote-sensing data and engaging with stakeholders. She was even first-author on a peer-reviewed paper.

“My work is basically using pictures [taken] from the sky that tell us information about the Earth and then making decisions about how to manage water resources and protect critical habitats,” she says.

Gustine is also well aware that her research comes at a pivotal time in the global conversation around Earth’s future.

“Given that climate change is having a profound impact on human and natural systems, we have to understand those changes and protect critical habitats and resources for the well-being of humans everywhere,” she says. “Changes in one component of a system can have cascading consequences for other parts of the system.”

While she works alongside others exploring the mysteries of worlds beyond Earth, Gustine is particularly proud to be part of pioneering research that could alter the future of our planet.

“Observing Earth is still space exploration, just from a different vantage point,” she says. “Given that NASA is the major proprietor of space, to look back at Earth using the same technology we use to go farther into space is important.”

Jonathan Vellanoweth

What will be the future, long-term impacts of power plants on our environment? Jonathan Vellanoweth is spending his time as a JPL intern working with a team to try to help answer that very question.

Vellanoweth is a student at Cal State University, Los Angeles, where he’s earning his master’s degree in environmental science with an emphasis in geospatial science. In his internship with the Surface Biology and Geology team at JPL, he's using data and satellite imagery from ECOSTRESS and the Landsat mission to detect thermal plumes emitted by power plants.

Vellanoweth’s work currently focuses on the Diablo Canyon Power Plant in San Luis Obispo, California.

“We’re looking at power plants that intake coastal waters to cool their reactors, then discharge it at a higher temperature back into the same water body,” he explains. “I’m using satellite imagery to detect that thermal change and outline the area of what is classified as a plume, or anywhere thermal discharge is heating up the ocean or the coast. We can see where this plume is moving over the year or several seasons, and other studies can use this data to see what the actual effects are on coastal communities.”

Vellanoweth has been fascinated by Earth science since as early as 7th grade, when he took his first environmental science class where he learned all about the scientific method and later went out into nature to collect soil samples and study them.

As a JPL intern, Vellanoweth has been particularly grateful for the variety of knowledge his colleagues provide him.

“The amount of support that you have from all these great scientists that work here is really what attracted me,” he says. “You can intern for a lot of places, but at JPL, you have all these colleagues you can meet with who have a lot of feedback they can give you. There are people on your team studying similar and dissimilar things as you, so they can provide you with something you might not have thought about and help expand your research.”

Most importantly, Vellanoweth is looking forward to the information everyone will have access to in the future thanks to the efforts of all the missions and projects within the Earth Science Observatory.

“I’m excited about getting things out there and making them accessible to the public. I’m really big on that because there are a lot of people who want to do this kind of research, but a lot of times, it can be hard to find the data or algorithm you need, and it’s a lot of trial and error,” he says. “SBG and ESO bring all of these things together and make it available for everyone.”


The laboratory’s STEM internship and fellowship programs are managed by the JPL Education Office. Extending the NASA Office of STEM Engagement’s reach, JPL Education seeks to create the next generation of scientists, engineers, technologists and space explorers by supporting educators and bringing the excitement of NASA missions and science to learners of all ages.

Learn about pi and some of the ways the number is used at NASA. Then, dig into the science behind the Pi Day Challenge.


Update: March 15, 2022 – The answers are here! Visit the NASA Pi Day Challenge slideshow to view the illustrated answer keys for each of the problems in the 2022 challenge.

In the News

No matter what Punxsutawney Phil saw on Groundhog Day, a sure sign that spring approaches is Pi Day. Celebrated on March 14, 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.

Every year, Pi Day gives us a reason to not only celebrate the mathematical wonder that helps NASA explore the universe, but also to enjoy our favorite sweet and savory pies. Students can join in the fun by using pi to explore Earth and space themselves in our ninth annual NASA Pi Day Challenge.

Read on to learn more about the science behind this year's challenge and find out how students can put their math mettle to the test to solve real problems faced by NASA scientists and engineers as we explore Earth, the Moon, Mars, and beyond!

How It Works

Dividing any circle’s circumference by its diameter gives you an answer of pi, which is usually rounded to 3.14. Because pi is an irrational number, its decimal representation goes on forever and never repeats. In 2021, a supercomputer calculated pi to more than 62 trillion digits. But you might be surprised to learn that for space exploration, NASA uses far fewer digits of pi.

Here at NASA, we use pi to understand how much signal we can receive from a distant spacecraft, to calculate the rotation speed of a Mars helicopter blade, and to collect asteroid samples. But pi isn’t just used for exploring the cosmos. Since pi can be used to find the area or circumference of round objects and the volume or surface area of shapes like cylinders, cones, and spheres, it is useful in all sorts of ways. Architects use pi when designing bridges or buildings with arches; electricians use pi when calculating the conductance of wire; and you might even want to use pi to figure out how much frozen goodness you are getting in your ice cream cone.

In the United States, March 14 can be written as 3.14, which is why that date was chosen for celebrating all things pi. 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 that's precisely what the NASA Pi Day Challenge is all about!

The Science Behind the 2022 NASA Pi Day Challenge

This ninth installment of the NASA Pi Day Challenge includes four brain-busters that get students using pi to measure frost deep within craters on the Moon, estimate the density of Mars’ core, calculate the water output from a dam to assess its potential environmental impact, and find how far a planet-hunting satellite needs to travel to send data back to Earth.

Read on to learn more about the science and engineering behind the problems or click the link below to jump right into the challenge.

Lunar Logic

NASA’s Lunar Flashlight mission is a small satellite that will seek out signs of frost in deep, permanently shadowed craters around the Moon’s south pole. By sending infrared laser pulses to the surface and measuring how much light is reflected back, scientists can determine which areas of the lunar surface contain frost and which are dry. Knowing the locations of water-ice on the Moon could be key for future crewed missions to the Moon, when water will be a precious resource. In Lunar Logic, students use pi to find out how much surface area Lunar Flashlight will measure with a single pulse from its laser.

Core Conundrum

Since 2018, the InSight lander has studied the interior of Mars by measuring vibrations from marsquakes and the “wobble” of the planet as it rotates on its axis. Through careful analysis of the data returned from InSight, scientists were able to measure the size of Mars’ liquid core for the first time and estimate its density. In Core Conundrum, students use pi to do some of the same calculations, determining the volume and density of the Red Planet’s core and comparing it to that of Earth’s core.

Dam Deduction

The Surface Water and Ocean Topography, or SWOT mission will conduct NASA's first global survey of Earth's surface water. SWOT’s state-of-the-art radar will measure the elevation of water in major lakes, rivers, wetlands, and reservoirs while revealing unprecedented detail on the ocean surface. This data will help scientists track how these bodies of water are changing over time and improve weather and climate models. In Dam Deduction, students learn how data from SWOT can be used to assess the environmental impact of dams. Students then use pi to do their own analysis, finding the powered output of a dam based on the water height of its reservoir and inferring potential impacts of this quick-flowing water.

Telescope Tango

The Transiting Exoplanet Survey Satellite, or TESS, is designed to survey the sky in search of planets orbiting bright, nearby stars. TESS does this while circling Earth in a unique, never-before-used orbit that brings the spacecraft close to Earth about once every two weeks to transmit its data. This special orbit keeps TESS stable while giving it an unobstructed view of space. In its first two years, TESS identified more than 2,600 possible exoplanets in our galaxy with thousands more discovered during its extended mission. In Telescope Tango, students will use pi to calculate the distance traveled by TESS each time it sends data back to Earth.

Teach It

Celebrate Pi Day by getting students thinking like NASA scientists and engineers to solve real-world problems in NASA Pi Day Challenge. Completing the problem set and reading about other ways NASA uses pi is a great way for students to see the importance of the M in STEM.
