Each year, 1,000 students come to NASA's Jet Propulsion Laboratory for internships at the place where space robots are born and science is made. Their projects span the STEM spectrum, from engineering the next Mars rover to designing virtual-reality interfaces to studying storms on Jupiter and the possibility of life on other planets. But the opportunity for students to "dare mighty things" at JPL wouldn't exist without the people who bring them to the Laboratory in the first place – the people known as mentors.
A community of about 500 scientists, engineers, technologists and others serve as mentors to students annually as part of the internship programs managed by the JPL Education Office. Their title as mentors speaks to the expansiveness of their role, which isn't just about generating opportunities for students, but also guiding and shaping their careers.
"Mentors are at the core of JPL's mission, pushing the frontiers of space exploration while also guiding the next generation of explorers," says Adrian Ponce, who leads the team that manages JPL's internship programs. "They are an essential part of the career pipeline for future innovators who will inspire and enable JPL missions and science."
Planetary scientist Glenn Orton has been bringing students to JPL for internships studying the atmospheres of planets like Jupiter and Saturn since 1985. He keeps a list of their names and the year they interned with him pinned to his office wall in case he's contacted as a reference. The single-spaced names take up 10 sheets of paper, and he hasn't even added the names of the students he's brought in since just last year.
It makes one wonder what he could need that many students to do – until he takes out another paper listing the 11 projects in which he's involved.
"I think I probably have the record for the largest number of [projects] at JPL," says Orton, who divides his time between observing Jupiter with various ground- and space-based telescopes, comparing his observations with the ones made by NASA's Juno spacecraft, contributing to a database where all of the above is tracked and producing science papers about the team's discoveries.
"Often, you get to be the first person in the world who will know about something," says Orton. "That's probably the best thing in the world. The most exciting moment you have in this job is when you discover something."
Over the years, Orton's interns have been authors on science papers and have even taken part in investigating unexpected stellar phenomena – like the time when a mysterious object sliced into Jupiter's atmosphere, sparking an urgent whodunnit that had Orton and his team of interns on the case.
Orton says his passion for mentoring students comes from the lack of mentorship he received as a first-generation college student. At the same time, he acknowledges the vast opportunities he was given and says he wants students to have them, too.
"As a graduate student, it was close to my first experience doing guided research, so I had no idea how research was communicated or conducted," says Orton of his time at Caltech, when he often worried that his classmates and professors would discover he wasn't "Nobel material." "I want to be able to work with students, which I sincerely enjoy, to instruct them on setting down a research goal, determining an approach, modifying it when things inevitably hit a bump, as well as communicating results and evaluating next steps."
For Alexandra Holloway and Krys Blackwood, the chance to provide new opportunities isn't just what drives them to be mentors, but also something they look for when choosing interns.
"I look for underdogs, students who are not representing themselves well on paper," says Holloway. "Folks from underrepresented backgrounds are less likely to have somebody guide them through, 'Here's how you make your résumé. Here's how you apply.' The most important thing is their enthusiasm for learning something new or trying something new."
It's for this reason that Holloway and Blackwood have become evangelists for JPL's small group of high-school interns, who come to the Laboratory through a competitive program sponsored by select local school districts. While less experienced than college students, high-school interns more than make up for it with perseverance and passion, says Blackwood.
"[High-school interns] compete to get a spot in the program, so they are highly motivated kids," she says. "Your results may vary on their level of skill when they come in, but they work so hard and they put out such great work."
Meet JPL Interns
Read stories from interns pushing the boundaries of space exploration and science at the leading center for robotic exploration of the solar system.
Holloway and Blackwood met while working on the team that designs the systems people use to operate spacecraft and other robotic technology at JPL – that is, the human side of robotics. Holloway has since migrated back to robots as the lead software engineer for NASA's next Mars rover. But the two still often work together as mentors for the students they bring in to design prototypes or develop software used to operate rovers and the antennas that communicate with spacecraft across the solar system.
It's important to them that students get a window into different career possibilities so they can discover the path that speaks to them most. The pair say they've seen several students surprised by the career revelation that came at the end of their internships.
"For all of our interns, we tailor the project to the intern, the intern's abilities, their desires and which way they want to grow," says Holloway. "This is such a nice place where you can stretch for just a little bit of time, try something new and decide whether it's for you or not. We've had interns who did design tasks for us and at the end of the internship, they were like, 'You know what? I've realized that this is not for me.' And we were like, 'Awesome! You just saved yourself five years.'"
The revelations of students who intern with Parag Vaishampayan in JPL's Planetary Protection group come from something much smaller in scale – microscopic, even.
Vaishampayan's team studies some of the most extreme forms of life on Earth. The group is trying to learn whether similar kinds of tough microbes could survive on other worlds – and prevent those on Earth from hitching a ride to other planets on NASA spacecraft. An internship in Planetary Protection means students may have a chance to study these microbes, collect samples of bacteria inside the clean room where engineers are building the latest spacecraft or, for a lucky few, name bacteria.
"Any researcher who finds a new kind of bacteria gets a chance to name it," says Vaishampayan. "So we always give our students a chance to name any bacterium they discover after whoever they want. People have named bacteria after their professors, astronauts, famous scientists and so forth. We just published a paper where we named a bacterium after Carl Sagan."
The Planetary Protection group hosts about 10 students a year, and Vaishampayan says he's probably used every JPL internship program to bring them in. Recently, he's become a superuser of one designed for international students and another that partners with historically black colleges and universities, or HBCUs, to attract students from diverse backgrounds and set them on a pathway to a career at the Laboratory.
"I can talk for hours and hours about JPL internships. I think they are the soul of the active research we are doing here," says Vaishampayan. "Had we not had these programs, we would not have been able to do so much research work." In the years ahead, the programs might become even more essential for Vaishampayan as he takes on a new project analyzing 6,000 bacteria samples collected from spacecraft built in JPL's clean rooms since 1975.
With interns making up more than 15 percent of the Laboratory population each year, Vaishampayan is certainly not alone in his affection for JPL's internship programs. And JPL is equally appreciative of those willing to lend time and support to mentoring the next generation of explorers.
Says Adrian Ponce of those who take on the mentorship role through the programs his team manages, "Especially with this being National Mentoring Month, it's a great time to highlight the work of our thriving mentor community. I'd like to thank JPL mentors for their tremendous efforts and time commitment as they provide quality, hands-on experiences to students that support NASA missions and science, and foster a diverse and talented future workforce."

The 2018 NASA Pi Day Challenge
Can you solve these stellar mysteries with pi? Click to get started.
Pi Day, the annual celebration of one of mathematics’ most popular numbers, is back! Representing the ratio of a circle’s circumference to its diameter, pi has many practical applications, including the development and operation of space missions at NASA’s Jet Propulsion Laboratory.
The March 14 holiday is celebrated around the world by math enthusiasts and casual fans alike – from memorizing digits of pi (the current Pi World Ranking record is 70,030 digits) to baking and eating pies.
JPL is inviting people to participate in its 2018 NASA Pi Day Challenge – four illustrated math puzzlers involving pi and real problems scientists and engineers solve to explore space, also available as a free poster! Answers will be released on March 15.
Why March 14?
Pi is what’s known as an irrational number, meaning its decimal representation never ends and it never repeats. It has been calculated to more than one trillion digits, but NASA scientists and engineers actually use far fewer digits in their calculations (see “How Many Decimals of Pi Do We Really Need?”). The approximation 3.14 is often precise enough, hence the celebration occurring on March 14, or 3/14 (when written in U.S. month/day format). The first known celebration occurred in 1988, and in 2009, the U.S. House of Representatives passed a resolution designating March 14 as Pi Day and encouraging teachers and students to celebrate the day with activities that teach students about pi.

To show students how pi is used at NASA and give them a chance to do the very same math, the JPL Education Office has once again put together a Pi Day challenge featuring real-world math problems used for space exploration. This year’s challenge includes exploring the interior of Mars, finding missing helium in the clouds of Jupiter, searching for Earth-size exoplanets and uncovering the mysteries of an asteroid from outside our solar system.
Here’s some of the science behind this year’s challenge:
Scheduled to launch May 5, 2018, the InSight Mars lander will be equipped with several scientific instruments, including a heat flow probe and a seismometer. Together, these instruments will help scientists understand the interior structure of the Red Planet. It’s the first time we’ll get an in-depth look at what’s happening inside Mars. On Earth, seismometers are used to measure the strength and location of earthquakes. Similarly, the seismometer on Insight will allow us to measure marsquakes! The way seismic waves travel through the interior of Mars can tell us a lot about what lies beneath the surface. This year’s Quake Quandary problem challenges students to determine the distance from InSight to a hypothetical marsquake using pi!
Also launching in spring is NASA’s Transiting Exoplanet Survey Satellite, or TESS, mission. TESS is designed to build upon the discoveries made by NASA’s Kepler Space Telescope by searching for exoplanets – planets that orbit stars other than our Sun. Like Kepler, TESS will monitor hundreds of thousands of stars across the sky, looking for the temporary dips in brightness that occur when an exoplanet passes in front of its star from the perspective of TESS. The amount that the star dims helps scientists determine the radius of the exoplanet. Like those exoplanet-hunting scientists, students will have to use pi along with data from Kepler to find the size of an exoplanet in the Solar Sleuth challenge.
Jupiter is our solar system’s largest planet. Shrouded in clouds, the planet’s interior holds clues to the formation of our solar system. In 1995, NASA’s Galileo spacecraft dropped a probe into Jupiter’s atmosphere. The probe detected unusually low levels of helium in the upper atmosphere. It has been hypothesized that the helium was depleted out of the upper atmosphere and transported deeper inside the planet. The extreme pressure inside Jupiter condenses helium into droplets that form inside a liquid metallic hydrogen layer below. Because the helium is denser than the surrounding hydrogen, the helium droplets fall like rain through the liquid metallic hydrogen. In 2016, the Juno spacecraft, which is designed to study Jupiter’s interior, entered orbit around the planet. Juno’s initial gravity measurements have helped scientists better understand the inner layers of Jupiter and how they interact, giving them a clearer window into what goes on inside the planet. In the Helium Heist problem, students can use pi to find out just how much helium has been depleted from Jupiter’s upper atmosphere over the planet’s lifetime.
In October 2017, astronomers spotted a uniquely-shaped object traveling in our solar system. Its path and high velocity led scientists to believe ‘Oumuamua, as it has been dubbed, is actually an object from outside of our solar system – the first ever interstellar visitor to be detected – that made its way to our neighborhood thanks to the Sun’s gravity. In addition to its high speed, ‘Oumuamua is reflecting the Sun’s light with great variation as the asteroid rotates on its axis, causing scientists to conclude it has an elongated shape. In the Asteroid Ace problem, students can use pi to find the rate of rotation for ‘Oumuamua and compare it with Earth’s rotation rate.

NASA is giving people around the world a reason to ooh and aah this July Fourth. At 8:18 p.m. PDT, as fireworks are streaming through the skies across the U.S., the Juno spacecraft will be taking the on-ramp to an orbit around Jupiter.
See the full problem set (optimized for screen readers and mobile devices) and answers, here
While maybe not as dramatic as a jet-powered landing on Mars, the Juno Orbit Insertion (the name for the process, also called JOI) requires that the spacecraft slow down just enough to not go zooming past Jupiter. As of Thursday, the spacecraft’s fate rested on a series of 1s and Os as a command sequence made the 48-minute journey from a gargantuan antenna in Goldstone, California, to the spacecraft 534 million miles away.
While a successful orbit insertion is now largely out of mission controllers’ hands, there will be no shortage of nail biting on July Fourth. With a five-year journey behind it and lofty goals ahead – which include peering through Jupiter’s thick cloud cover to uncover clues about how our solar system was formed – Juno has a lot resting on what will amount to a 35-minute engine burn. And perhaps even bigger risks are still to come as Juno begins its 33.5 oblong orbits around Jupiter, which will bring the spacecraft closer than ever before to the planet’s cloud tops – and to its lethal radiation.
To follow along on July 4 as Juno begins its journey into Jupiter’s orbit, watch NASA TV live coverage beginning at 7:30 p.m. PDT.

In the News
NASA’s Juno mission, the first solar-powered mission to Jupiter, has become the farthest solar-powered spacecraft ever! Juno, and its eight science instruments designed to study the interior of Jupiter, has passed the mark previously held by the European Space Agency’s Rosetta mission and reached a distance of 5.3 astronomical units from the sun (an astronomical unit is equal to the average distance between Earth and the sun – about 149.6 million kilometers). Using only power from the sun, Juno will complete the five-year trip to Jupiter in July 2016 and begin studying the solar system’s most massive world in an attempt to better understand the origins of the planet, and in turn, our solar system.
What Made It Possible
Just as a bright source of light dims as you move away from it, sunlight becomes less intense the farther a spacecraft travels from the sun, limiting the amount of power that can be generated using solar cells. Previous missions that visited Jupiter, like Galileo, Voyager 1 and Voyager 2, couldn’t use solar power and instead used radioisotope thermoelectric generators (RTGs) to supply power.
Advances in solar panel efficiency along with improvements in the way spacecraft and their instruments use power have recently made solar power a viable option for spacecraft heading as far as Jupiter – though going beyond will require further technological advances.
Engineers designed Juno with three massive solar panels, each nearly 30 feet long. Combined, they provide Juno with 49.7 m2 of active solar cells. Once it reaches Jupiter, Juno will generate more than 400 watts of power, which may not sound like a lot, but it’s an impressive feat at so great a distance. For comparison, Juno’s solar panels can generate about 14 kilowatts near Earth.
Juno's record-setting achievement translates into a powerful lesson in exponents.
Middle school students and other students working with exponents will find challenging, real-world applications related to the work being done here at NASA while addressing four Common Core Math standards:
- Grade 6: Expressions and Equations A.1 - "Write and evaluate numerical expressions involving whole-number exponents."
- Grade 6: Expressions and Equations A.2 - "Write, read, and evaluate expressions in which letters stand for numbers."
- Grade 6: Expressions and Equations A.2.C - "Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations)."
- Grade 8: Expressions and Equations A.1 - "Know and apply the properties of integer exponents to generate equivalent numerical expressions. For example, 32 × 3-5 = 3-3 = 1/33 = 1/27."
