Almost a decade ago, then-grad student Kyle Helson contributed to early paperwork for NASA’s EXCITE mission. As a scientist at Goddard, Helson helped make this balloon-based telescope a reality: EXCITE launched successfully on Aug. 31.
Name: Kyle Helson
Title: Assistant Research Scientist
Organization: Observational Cosmology Lab (Code 665), via UMBC and the GESTAR II cooperative agreement with NASA Goddard

When I was finishing my physics Ph.D. at Brown University in 2016, I was talking to Ed Wollack and Dave Chuss at Goddard about the NASA postdoc program, and they suggested I apply. Luckily, I got the postdoc fellowship to come here to Goddard to work on cosmic microwave background detector testing and other related research.
I don’t think I would have realized or been interested in coming here had I not had that NASA Space Technology Research Fellowship when I was in grad school and gotten the opportunity to spend some time here and work with Ed and Dave.
What is the name of your team that you’re working with right now?
One of the projects I work on is the Exoplanet Climate Infrared TELescope (EXCITE). EXCITE is a scientific balloon-borne telescope that is designed to measure the spectra of hot, Jupiter-like exoplanet atmospheres in near-infrared light.
Related: NASA’s EXCITE Mission Prepared for Scientific Balloon Flight What is your role for that?
I do a little bit of everything. During grad school, I worked on the first few iterations of the proposal for EXCITE back in 2015 and 2016.
Over the past few years here at Goddard, I’ve been responsible for parts of a lot of the different subsystems like the cryogenic receiver, the gondola, the electronics, and integration and testing of the whole payload.
Last year, we went to Fort Sumner, New Mexico, for an engineering flight. Unfortunately, we were not able to fly for weather reasons. We went back last month, and I was again part of the field deployment team. We take the whole instrument, break it down, carefully ship it all out to New Mexico, put it back together, test it, and get it ready for a flight.

What I like about working on a project like EXCITE is that we get to kind of do a little bit of everything.
We’ve been able to see the experiment from concept and design to actually getting built, tested and hopefully flown and then subsequent data analysis after the flight. What I think is really fun is being able be with an experiment for the entire life cycle.
How do you help support Goddard’s mission?
We’re studying exoplanets, which definitely fits within the scientific mission of Goddard. We’re also a collaboration between Goddard other academic institutions, like Arizona State, like Brown University, Cornell, and several other places, and so we’re also members of the larger scientific research community beyond NASA.
We also have a number of graduate students working on EXCITE. Ballooning is a good platform for training students and young researchers to learn how to build and design instruments, do data analysis, etc. One of the missions of NASA and Goddard is to train early career scientists like graduate students and post docs, and balloons provide a good platform for that as well.
Balloon missions like EXCITE also provide a good platform for technology advancement and demonstration in preparation for future satellite missions.
How did you know cosmology was what you wanted to pursue?
When I was a kid, I loved space. I wanted to be an astronaut when I was a kid. I even went to space camp.
The first time I ever got to see physics was a middle-school science class. That was the first time we ever learned physics or astronomy that was deeper than just identifying planets or constellations. We started to learn how we could use math to measure or predict experiments.
When I was in college, I remember talking to my undergraduate academic adviser, Glenn Starkman, and talking about what research I might like to do over the summer between sophomore and junior year of college. I wasn’t really sure what I wanted to do or what I was interested in, and he suggested I talk to some of the professors doing astrophysics and cosmology research and see if they had space for me in their lab.
I ended up finding a great opportunity working in a research lab in college — so it was working in the physics department in Case Western.
That’s where I first started learning about computer-aided design (CAD), and designing things in CAD, and that’s where I first learned how things get made in a machine shop, like on a mill, or a lathe. These skills have come in handy ever since, because I do a lot of design work in the lab. And I was lucky growing up that my dad was really hands-on and liked to fix things and build things and he taught me a lot of those skills as well.

My dad had a big influence. I think all the different people I’ve had the opportunity to learn from and work with who have been mentors along the way. My research advisers, professor John Ruhl in college, professor Greg Tucker in grad school, and Dr. Ed Wollack as a postdoc have all been very influential. Additionally, I have had the opportunity to work with a lot of very good post docs and research scientists during my career, Dr. Asad Aboobaker, Dr. Britt Reichborn-Kjennerud, Dr. Michele Limon, among others.
Throughout a career, there are tons of other people on the way from whom you pick up little things here and there that stick with you. You look back and you realize five years later you still do this one thing a certain way because someone helped you and taught you this skill or technique.
Where is a place you’d like to travel to?
Since I was lucky enough to go to Antarctica in graduate school, I figured that is the hardest continent to travel to, so now I have a mission to go to every continent. I’ve been to North America, I’ve been to South America, I’ve been to Asia, Europe, and Australia and New Zealand, but I’ve never been to Africa.

I’m a competitive track cyclist. I started racing bikes in collegiate racing as a grad student at Brown. Many summers I’ve spent many weekends driving and flying all over the U.S. to race in the biggest track cycling events in the country.
What would be your three-word-memoir?
Curious, compassionate, cat-dad.

NASA’s Advanced Composite Solar Sail System is seen orbiting Earth in this 13-second exposure photograph, Monday, Sept. 2, 2024, from Arlington, Virginia. The mission team confirmed the spacecraft’s unique composite boom system unfurled its reflective sail on Thursday, Aug. 29, 2024, accomplishing a critical milestone in the agency’s demonstration of next-generation solar sail technology that will allow small spacecraft to “sail on sunlight.” Just as a sailboat is powered by wind in a sail, a spacecraft can use the pressure of sunlight on a solar sail for propulsion. This technology demonstration serves as a pathfinder for future missions powered by solar sail technology.NASA/Bill Ingalls Now that its reflective sail has deployed fully open in orbit, the Advanced Composite Solar Sail System can be seen in the night sky from many locations across the world!
Stargazers can join NASA’s #SpotTheSail campaign by using the NASA app on mobile platforms to find out when the spacecraft will be visible at their location. The app, which is free to use and available on iOS and Android, provides a location-specific schedule of upcoming sighting opportunities. A built-in augmented reality tool points users to the location of the spacecraft in real time.
Can you spot the solar sail? Share your viewing experience online using the hashtag #SpotTheSail for a chance to be featured on NASA’s website and social media channels.
Here’s how to use the sighting prediction tool:
Install and open the NASA app on an iOS or Android device. Tap on the “Featured” tab on the bottom navigation bar. Tap on the Advanced Composite Solar Sail System mission from the Featured Missions at the top of the screen. Tap on the “Sightings” tab on the bottom navigation bar. A list of all the upcoming sightings for your location will be displayed. If you are using an iOS device, you can tap on the “Sky View” link for an augmented reality guide to help you locate the spacecraft’s real-time location during the visible pass. NASA’s Advanced Composite Solar Sail System is testing new technologies in low Earth orbit, including a composite boom system that supports a four-piece sail. Not to be confused with solar panels, solar sails allow small spacecraft to “sail on sunlight,” eliminating the need for rocket fuel or other conventional propellants. This propulsion technology can enable low-cost deep space missions to increase access to space.

ESA’s Solar Orbiter spacecraft has provided crucial data to answer the decades-long question of where the energy comes from to heat and accelerate the solar wind. Working in tandem with NASA’s Parker Solar Probe, Solar Orbiter reveals that the energy needed to help power this outflow is coming from large fluctuations in the Sun’s magnetic field.

How NASA Citizen Science Fuels Future Exoplanet Research
This artist’s concept shows the exoplanet K2-33b transiting its host star. Many citizen science projects at NASA invite the public to use transit data to make discoveries about exoplanets. NASA/JPL-Caltech NASA’s upcoming flagship astrophysics missions, the Nancy Grace Roman Space Telescope and the Habitable Worlds Observatory, will study planets outside our solar system, known as exoplanets. Over 5,000 exoplanets have been confirmed to date — and given that scientists estimate at least one exoplanet exists for every star in the sky, the hunt has just begun. Exoplanet discoveries from Roman and the Habitable Worlds Observatory may not be made only by professional researchers, but also by interested members of the public, known as citizen scientists.
Exoplanet research has a long involvement with citizen science. NASA’s TESS (Transiting Exoplanet Survey Satellite) mission and now-retired Kepler mission, which are responsible for the vast majority of exoplanet discoveries to date, both made observations freely available to the public immediately after processing. This open science policy paved the way for the public to get involved with NASA’s exoplanet science.
NASA’s Planet Hunters TESS project invites the public to classify exoplanet light curves from TESS online. Another project, Exoplanet Watch, allows citizen scientists to gather data about known exoplanets, submit their observations to NASA’s public data archive, and receive credit if their observation is used in a scientific paper. Participants don’t even need their own telescope — Exoplanet Watch also curates data from robotic telescopes for users to process.
Artist’s concept of NASA’s TESS (Transiting Exoplanet Survey Satellite). Data from TESS have been used in citizen science projects. NASA’s Goddard Space Flight Center “Anyone across the world who has access to a smartphone or a laptop can fully participate in a lot of these citizen science efforts to help us learn more about the cosmos,” said Rob Zellem, the project lead and project scientist for Exoplanet Watch and astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
NASA’s citizen science projects have discovered several new planets from Kepler and TESS data. They have also helped scientists refine the best time to observe important targets, saving hours of precious observation time on current flagship missions like NASA’s James Webb Space Telescope.
Roman and the Habitable Worlds Observatory provide even more possibilities for citizen science. Expected to launch by May 2027, Roman will discover exoplanets through direct imaging, transits, and gravitational microlensing. Following that, the Habitable Worlds Observatory will take direct images of stars in our solar neighborhood to find potentially habitable planets and study their atmospheres.
The general public can get Roman data as quickly as I can as a scientist working on the mission.

Like Kepler and TESS before them, data from Roman and the Habitable Worlds Observatory will be available to both the scientific community and the public immediately after processing. With Roman’s surveys expected to deliver a terabyte of data to Earth every day — over 17 times as much as Webb — there is a huge opportunity for the public to help sift through the information.
“The general public can get Roman data as quickly as I can as a scientist working on the mission,” said Zellem, who also serves as Roman’s deputy project scientist for communications at NASA Goddard. “It truly makes Roman a mission for everyone and anyone.”
Although the Habitable Worlds Observatory’s full capabilities and instrumentation have yet to be finalized, the inclusion of citizen science is expected to continue. The team behind the mission is embracing a community-oriented planning approach by opening up working groups to volunteers who want to contribute.
“It’s already setting the tone for open science with the Habitable Worlds Observatory,” said Megan Ansdell, the program scientist for the mission at NASA Headquarters in Washington. “The process is as open as possible, and these working groups are open to anybody in the world who wants to join.” There are already over 1,000 community working group members participating, some of whom are citizen scientists.
The Roman Coronagraph, photographed during testing at NASA’s Jet Propulsion Lab in Southern California, is a technology demonstration designed to block starlight and allow scientists to see the faint light from planets outside our solar system. It represents one of multiple ways that Roman will contribute to exoplanet research. NASA/JPL-Caltech Future citizen science initiatives may be combined with cutting-edge tools such as artificial intelligence (AI) for greater efficacy. “AI can be exceptionally powerful in terms of classification and identifying anomalous things,” said Joshua Pepper, the deputy program scientist for the Habitable Worlds Observatory at NASA Headquarters. “But the evaluation of what those anomalous things are often requires human insight, intervention, and review, and I think that could be a really fantastic area for citizen scientists to participate.”
Before Roman and the Habitable Worlds Observatory launch, exoplanet citizen scientists still have plenty of data to analyze from the Kepler and TESS satellites, but the contributions of the community will become even more important when data begin pouring in from the new missions. As Zellem said, “We’re in a golden age of exoplanet science right now.”
NASA’s citizen science projects are collaborations between scientists and interested members of the public and do not require U.S. citizenship. Through these collaborations, volunteers (known as citizen scientists) have helped make thousands of important scientific discoveries.
