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.

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.

What are you working on at JPL?

I worked on this project called OnSight, which just won NASA Software of the Year! I also worked on another project for the InSight Mars lander mission. Honestly, it’s been such a dream come true to intern here. I actually used to struggle a lot with school because I would often get caught up in my own daydreams. However, I’m really glad I found a unique career path in VR where I can turn those dreams into something useful.

That's so great that you were able to channel your daydreams in that way. How did you go from struggling in school to doing VR?

When I first tried on a VR headset, I was like, "This is the future. I need to do whatever I can to learn about this." I decided to study computer science, but it was easy to get lost and fall behind in a large classroom environment. Not a lot of people know this, but I was on academic probation for a while. Looking back, I think my shyness held me back from asking for the help that I needed.

When I took a break from school, I decided I wanted to try making a game. I wanted to do something just for fun, and I was determined to fix my bad habits. So with some friends, I created a self-help game at AthenaHacks, a women’s hackathon. For 24 hours, I was just immersed in my work. I had never felt that way about anything in my life, where I was just zoned in, in my own world, building something I loved. And that's when I realized, I think it's game development. I think this is what I want.

So I spent the year teaching myself [game development], and I got a lot more comfortable using the Unity game engine. I went on to attend Make School’s VR Summer Academy in San Francisco. That smaller learning environment opened up the world for me. It boosted my confidence more than anything to have the support I needed. I was like, "Maybe my grades aren’t so great, but I know how to build VR applications – and the world needs VR right now.”

So when I went back to my university, I thought, "I'll try again. I'm going to go back to computer science.” And so far so good. I'm into my fourth year at UCLA studying cognitive science, linguistics, computer science and digital humanities. It sounds like a lot, but they're all related in the sense that they're all connected to VR. To me, VR is mainly a study of the mind and how we perceive reality. It’s not just about game development; you also need to understand human behavior to create good user-friendly VR.

So going back to your JPL internship, how are you using your VR skills to help scientists and engineers?

I’m interning in the Ops Lab, and the project I've been working on primarily is called OnSight. OnSight uses Microsoft’s HoloLens [mixed-reality software] to simulate walking on Mars. Mars scientists use it to collaborate with each other. We had “Meet on Mars” this morning, actually. On certain days, Mars scientists will put on their headsets and hang out virtually on Mars. They see each other. They talk. They look at Mars rocks and take notes. It's based on images from the Curiosity Mars rover. We converted those images to 3-D models to create the virtual terrain, so through VR, we can simulate walking on Mars without being there.

For a few weeks, I worked on another project with the InSight Mars lander mission. We took the terrain model that's generated from images of [the landing site] and made it so the team could see that terrain on top of their testbed [at JPL] with a HoloLens. For them, that's important because they're trying to recreate the terrain to … Wait, I recorded this.

[Michelle quickly scans through the photo library on her phone and pulls up a video she recorded from JPL’s In-Situ Instruments Laboratory. Pranay Mishra, a testbed engineer for the InSight mission, stands in a simulated Mars landscape next to a working model of the lander and explains:]

“When InSight reaches Mars, we're going to get images of the terrain that we land on. The instruments will be deployed to that terrain, so we will want to practice those deployments in the testbed. One of the biggest things that affects our deployment ability is the terrain. If the terrain is tilted or there are rocks in certain spots, that all has a strong effect on our deployment accuracy. To practice it here, we want the terrain in the testbed to match the terrain on Mars. The only things we can view from Mars are the images that we get back [from the lander]. We want to put those into the HoloLens so that we can start terraforming, or “marsforming,” the testbed terrain to match the terrain on Mars. That way, we can maybe get a rough idea of what the deployment would look like on Mars by practicing it on Earth.”

They already gave us photos of Mars, which they turned into a 3D model. I created an AR project, where you look through the HoloLens – looking at the real world – and the 3D model is superimposed on the testbed. So the [testbed team] will shovel through and shape the terrain to match what it’s like on Mars, at InSight’s landing site.

Did you know that this was an area that you could work in at JPL before interning here?

OnSight was a well known project in the VR/AR space, since it was the first project to use the Microsoft Hololens. I remember being excited to see a panel on the project at the VRLA conference. So when I finally got on board with the team, I was ecstatic. I also realized that there’s room for improvement, and that’s OK. That’s why I'm here as an intern; I can bring in a fresh look.One of the things I did on this project was incorporate physical controllers. My critique when I first started was, "This interface is a bit tricky to use," and if it's challenging for me to use as a millenial, how is this going to be usable for people of all ages? I try to think in terms of accessibility for everybody. Through lots of testing, I realized that people need to be touching things, physical things. That's what OnSight lacked, a physical controller. There were a lot of things that I experimented with, and eventually, it came down to a keyboard that allows you to manipulate the simulated Mars rovers. So now with OnSight, you can drive the [simulated] rovers around with a keyboard controller and possibly in the future, type notes within the application. Previously, you had to tap into the air to use an AR keyboard, and that's not intuitive. I believe we still need to touch the physical world.

How has this project compared with other ones that you've done elsewhere?

I felt really in my element. And for the first time ever, the imposter-syndrome voice went away. I felt like I could just be myself and actually have a voice to contribute. You know, I might be small, I might be the shortest one, but I'm mighty. It’s been such a positive and supportive environment. I've had an incredible internship and learned so much.

What has been the most unique experience that you've had at JPL?

Working in the Ops Lab has been such a unique experience. Every day, we’re tinkering with cutting-edge technology in AR and VR. I am so thankful to have my mentors, Victor Luo and Parker Abercrombie, who give me the support and guidance I need to grow and learn. Outside of the Ops Lab, I also had the unique opportunity to meet astronaut Kate Rubins and talk about VR with her. I had lunch with NASA Administrator Jim Bridenstine when he visited JPL. And working with the InSight mission and Marleen Sundgaard, the mission’s testbed lead, was especially cool. I can't believe I was able to use my skills for something the Mars InSight mission needed. Being able to say that is something I'm really proud of. And seeing how far I came, from knowing nothing to being here, makes me feel happy. If I can transform, anyone can do this too, if they choose to work hard, follow their own path and see it in themselves to take a risk.

What advice do you have for others looking to follow your path?

Listen to your gut. Your gut knows. It’s easy to feel discouraged when learning something new, but trust me, you’re not alone. You’ve always got to stay optimistic about finding a solution. I've always been someone who has experimented with a lot of things, and I think learning is something you should definitely experiment with. If the classroom setting is not for you, try teaching yourself, try a bootcamp, try asking a friend – just any alternative. There is nothing wrong with carving your own path when it comes to your education. Everyone’s at their own pace, just don’t give up!

My biggest inspiration is the future. I think about it on a daily basis. I know I have a very cheery, idealistic view on life, but I think, "What's wrong with that?" as long as you can bring it back to reality.

Speaking of that, what is your ultimate dream for your career and your future?

I was raised in the Bay Area, and I grew up in Santa Clara so the tech culture of Silicon Valley was inescapable. I love Silicon Valley, but there is still a huge homelessness issue. I’ve always thought, “We have the brightest engineers and scientists doing the most amazing, crazy things, yet we still can't alleviate homelessness.” Everybody deserves a place to sleep and shower. People need to have their basic needs met. I’d love to see some sort of VR wellness center that could help people train for a job, overcome fears and treat mental health.

That's my idealistic dream, but back to present-day dreams: I'm actually doing a 180. I'm leaving tech for a little bit, and I’m taking Fall quarter off. I'll start back at UCLA in January, but I'm taking a leave to explore being an artist. I'm writing a science-fiction play about Vietnamese-American culture. I was inspired by my experience here at JPL. I feel really optimistic about the future of technology, which is funny because science fiction usually likes to depict tech as something crazy, like an apocalypse or the world crashing down. But I'm like, “Vietnamese people survived an actual war, and they’re still here.” For my parents and grandparents, their country as they knew it came crashing down on them when they were just about my age. They escaped Vietnam by boat and faced many hardships as immigrants who came to America penniless and without knowing English. For them to have survived all of that and sacrificed so much to make it possible for me to be here is incredible. I think it’s a testament to how, despite the worst things, there's always good that continues. I’m so grateful and thankful for my family. I wouldn’t be here living my dream without them, and I want to create a play about that.

It's funny. Before I used to be so shy, so shy. I used to be that one kid who would never talk to anybody. So it's kind of nice to see what happens when the introvert comes out of her shell. And this is what happens. All of this. [Laughs.]

  William Lopez-Cordero, Student, Massachusetts Institute of Technology

  William Lopez-Cordero studies aerospace engineering at the Massachusetts Institute of Technology. He interned at NASA's Jet Propulsion Laboratory in the summer of 2014, developing new software architecture to model spacecraft operations.

NASA's Curiosity Mars rover this week completed its first Martian year -- 687 Earth days -- since landing in August 2012. Each day of the rover working on Mars requires several dozen rover team members completing tasks on Earth.

To celebrate reaching this longevity milestone, which had been set as one of the mission's goals from the start, the Curiosity team planned staffing a special day, with women fulfilling 76 out of 102 operational roles.

"I see this as a chance to illustrate to girls and young women that there's not just a place for them in technical fields, but a wide range of jobs and disciplines that are part of the team needed for a project as exciting as a rover on Mars," said Colette Lohr, an engineer at NASA's Jet Propulsion Laboratory, Pasadena, California.

"There's no practical way any one person could learn all the disciplines needed for operating Curiosity," she said. "It takes a team and we rely on each other."

Disciplines range from soil science to software engineering, from chemistry to cartography, in duties ranging from assessing rover-temperature data freshly arriving from Mars to choosing where to point the rover's cameras. Descriptions of the roles, along with names and locations of the team members filling them today, are part of Curiosity Women's Day information available at:

http://go.usa.gov/9d3x

Lohr's role today is strategic mission manager, which means she is responsible for review and approval of plans being developed and modified during the day for rover activities more than three or four days in the future.

She and most of the other engineers and managers on the team are at JPL in California. Today's team, not atypically, also includes members working in 11 other U.S. states, from Massachusetts to Montana, and four other nations: Canada, France, Russia and Spain. Each of the rover's 10 science instruments has people responsible for evaluating newly received data and planning to get more data. Other scientists participating in operations serve on theme groups that pull together information from multiple instruments and choose priorities for upcoming activities.

Curiosity Deputy Project Scientist Joy Crisp of JPL helped organize the special day and will fill the project scientist role, providing scientific leadership in the strategic planning process. She said, "The team has both scientists and engineers, but it's one team working together to accomplish the mission goals."

Each day's rover activities must be planned to fit within budgets of how much time, power and data-downlink capacity are available.

The operational roles fall into categories of tactical, supra-tactical and strategic, which focus, respectively, on the next day's rover activities, the activities two to five days ahead, and planning for weeks or months ahead.

"While some people are focused on today's plan for tomorrow, we need other people to be looking further ahead," Crisp said. "We wouldn't be able to plan complex activities for the rover if we started from scratch each day. We do a lot of work to get a head start on each day."

The operations team for Curiosity is larger than the operations teams for the previous generation of rovers, NASA's Mars Exploration Rovers Spirit and Opportunity. In an experience similar to Women's Curiosity Day, one day in February 2008, Spirit's tactical operations team of about 30 people was almost entirely women.

NASA's Mars Science Laboratory Project is using Curiosity to assess ancient habitable environments and major changes in Martian environmental conditions. JPL, a division of the California Institute of Technology in Pasadena, built the rover and manages the project for NASA's Science Mission Directorate in Washington.

  ABOUT THE AUTHOR

  NASAJPL News

  The news office at NASA's Jet Propulsion Laboratory covers mission events, science and discoveries from JPL’s dozens of active space missions exploring Earth, the solar system and worlds beyond. Read the latest news from NASAJPL

A couple of years later, I found myself studying aerospace engineering at The University of Texas at Austin and learning about spacecraft design and space systems engineering. My adviser, Dr. Hans Mark, helped me apply for a summer internship at JPL during my sophomore year.

At this point, I knew little to nothing about what I really wanted to do as an aerospace engineer. I just knew I wanted to work for NASA and help scientists answer some fundamental questions about our universe, such as, "Are we alone?" or, "Is there water on Mars?"

During my first summer internship at JPL, I was part of a team of students who were tasked with designing a secondary payload for the proposed MoonRise mission. MoonRise would have been the first robotic sample-return mission from the moon. We designed a camera system that would have flown on the communications satellite and detected impact flashes from impacting meteorites.

MoonRise was not selected to fly, but this extraordinary experience completely changed my career path.

After my first summer internship at JPL, I knew exactly what I wanted to do as an aerospace engineer. I wanted to help formulate and design innovative concepts.

The next summer, I was fortunate to come back to JPL and work on the Mars Science Laboratory as a flight software team member. We were creating a platform to test the wake cycle robustness of the Curiosity rover. This once-in-a-lifetime opportunity changed me forever. Not many people can say they worked on a rover that is currently on another planet. JPL made that possible for me.

At this point, I had my mind and heart set on getting a job at JPL upon graduation, so I came back to JPL as an intern for the third time during my senior year. This time, I was tasked with working at JPL's state-of-the-art concurrent engineering facility called Team X. I had come full circle to what I was most passionate about, formulation and systems engineering.

Meanwhile, in my free time back at UT-Austin, I was designing my own mission with CubeSats -- small satellites that can fit inside a 10-centimeter cube. With the help of my other aerospace engineer friends I proposed a CubeSat constellation to detect Earth-like planets by measuring the interaction between the stellar solar wind and the magnetosphere of the exoplanets.

I graduated from UT-Austin in December of 2012 with the highest of honors and received the "2012 Cockrell School of Engineering Scholar-Leader Award" from the dean of the engineering school. None of this would have been possible without the invaluable experience I gained as an intern at JPL. The internships at JPL were real hands-on opportunities on real projects. JPL empowered me as an intern and gave me real responsibilities and tasks that everyone on the team truly cared about. My three summer internships at JPL before graduation gave me the tools and fundamentals I needed to excel in any work environment immediately after graduation.

So now I work at JPL on formulation projects as a systems engineer. I have already sponsored interns at JPL as a mentor, and I love the fact that there is no limitation to how fast you can grow here. I am currently the project systems engineer and flight systems engineer on an interplanetary CubeSat mission and work on a variety of different innovative concepts on the side.

In my free time, I go to local schools to talk to students and motivate them to pursue science, technology, engineering and math (STEM) degrees.

JPL was the tipping point in my career. Not only did I gain invaluable technical expertise from my internships, but I also gained the confidence and communication skills vital for any engineer, and especially for a systems engineer.
