Citizen Scientists Use NASA Open Science Data to Research Life in Space
2023 Workshop of Analysis Working Group members, Washington, D.C., November 14, 2023. Now, you are invited to join their quest to understand how life can thrive in deep space! Want to learn more first? Join our live virtual event April 17 at 3pm Eastern Time to hear an overview of the OSDR AWG’s operations. Photo: NASA OSDR Team How can life thrive in deep space? The Open Science Data Repository Analysis Working Groups invite volunteers from all backgrounds to help answer this question. Request to join these citizen science groups to help investigate how life adapts to space environments, exploring topics like radiation effects, microgravity’s impact on human and plant health, and how microbes change in orbit.
Currently, nine Analysis Working Groups (AWGs) hold monthly meetings to advance their specific focus areas. Participants collaborate using an online platform, the AWG “Forum-Space”, where they connect with peers and experts, join discussions, and contribute to over 20 active projects.
The AWGs work with data primarily from the NASA Open Science Data Repository (OSDR), a treasure trove of spaceflight data on physiology, molecular biology, bioimaging, and much more. For newcomers, there are tutorials and a comprehensive paper covering all aspects of the repository and the AWG community. You can explore 500+ studies, an omics multi-study visualization portal, the environmental data app, and RadLab, a portal for radiation telemetry data. (“Omics” refers to fields of biology that end in “omics,” like “genomics”.)
Each of the nine AWGs has a Lead who organizes their group and holds monthly virtual meetings. Once you join, make sure to connect with the Lead and get on the agenda so you can introduce yourself. Learn more about the AWGs here.
Have an idea for a new project? Propose a new project and help lead it! From data analysis and visualization to shaping data standards and conducting literature meta-analyses, there’s a place for everyone to contribute. Request to join, and together, we can address a great challenge for humanity: understanding and enabling life to thrive in deep space!
Want to learn more?
On April 17 at 3pm Eastern Time, the NASA Citizen Science Leaders Series is hosting an virtual event with Ryan Scott about these Analysis Working Groups and their work. Ryan is the Science Lead for the Ames Life Sciences Data Archive and the liaison between the Open Data Science Repository and the Analysis Working Groups. Click here to register for this event!

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA astronaut Douglas Hurley is helped out of the SpaceX Crew Dragon Endeavour spacecraft onboard the SpaceX GO Navigator recovery ship after he and NASA astronaut Robert Behnken landed in the Gulf of Mexico off the coast of Pensacola, Florida, Sunday, Aug. 2, 2020. The Demo-2 test flight for NASA’s Commercial Crew Program was the first to deliver astronauts to the International Space Station and return them safely to Earth onboard a commercially built and operated spacecraft. Behnken and Hurley returned after spending 64 days in space.

Additionally, the crew may be deconditioned on landing, impacting their ability to independently egress the vehicles, perform post-landing tasks in a timely manner, and perform surface EVAs post-landing -including those required for emergencies.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
That’s a great question. And it’s a question that NASA will seek to answer with the Europa Clipper spacecraft.
Europa is a moon of Jupiter. It’s about the same size as Earth’s Moon, but its surface looks very different. The surface of Europa is covered with a layer of ice, and below that ice, we think there’s a layer of liquid water with more water than all of Earth’s oceans combined.
So because of this giant ocean, we think that Europa is actually one of the best places in the solar system to look for life beyond the Earth.
Life as we know it has three main requirements: liquid water — all life here on Earth uses liquid water as a basis.
The second is the right chemical elements. These are elements like carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur. They’re elements that create the building blocks for life as we know it on Earth. We think that those elements exist on Europa.
The third component is an energy source. As Europa orbits around Jupiter, Jupiter’s strong gravity tugs and pulls on it. It actually stretches out the surface. And it produces a heat source called tidal heating. So it’s possible that hydrothermal systems could exist at the bottom of Europa’s ocean, and it’s possible that those could be locations for abundant life.
So could there be life on Europa? It’s possible. And Europa Clipper is going to explore Europa to help try to answer that question.

For more than a decade, Tristan McKnight has been a driving force behind some of NASA’s most iconic events, orchestrating the behind-the-scenes magic that brings each historic moment to life while sharing the agency’s advancements with the public.
As a multimedia producer on the audiovisual team at Johnson Space Center in Houston, McKnight produces and directs live broadcasts and manages event planning, coordination, and execution. From overseeing resources, mitigating risks, and communicating with stakeholders, he ensures every detail aligns seamlessly.
Official portrait of Tristan McKnight.NASA/Josh Valcarcel McKnight has played an integral role in the audiovisual team’s coverage of major events including the Artemis II crew announcement, where NASA revealed the astronauts who will venture around the Moon and back, to Johnson’s 2023 Open House, which celebrated the agency’s 65th anniversary and the 25th anniversary of the International Space Station’s operations. These achievements highlight key milestones in human space exploration.
A standout achievement was contributing to the Dorothy Vaughan Center in Honor of the Women of Apollo naming ceremony, held on the eve of the 55th anniversary of the Apollo 11 Moon landing. The event honored the unsung heroes who made humanity’s first steps on the Moon possible.
The team’s dedication and passion are a testament to their commitment to sharing NASA’s legacy with the world.
“Not only have these events been impactful to Johnson, but they have also resonated across the entire agency,” McKnight said. “That is what I’m most proud of!”

McKnight recalled how the speaker transformed Johnson’s Teague Auditorium into a venue filled with drum kits, inspiring messages, and lighting displays. Each audience member, drumsticks in hand, participated in a lesson on teamwork and synchronization to create a metaphor for working in harmony toward a shared goal.
Like many high-achieving professionals. McKnight has faced moments of self-doubt. Then he realized that he is exactly where he is supposed to be. “As I settled into my role, I recognized that my contributions matter and simply being true to who I am adds value to the Johnson community,” he said.

One of McKnight’s most valuable lessons is recognizing that there is no one-size-fits-all solution, and each situation requires a thoughtful analysis.
McKnight understands the importance of the “check-and double-check,” a philosophy he considers crucial when working with technology. “Taking the extra time to do your due diligence, or even having someone else take a look, can make all the difference,” he said.
“The challenges I’ve faced helped me grow as a problem solver and taught me valuable lessons on resilience and adaptability in the workplace,” he said. McKnight approaches obstacles with a level head, focusing on effective solutions rather than dwelling on the problem.

NASA/Helen Arase Vargas As humanity looks to the stars, McKnight is energized about the future of exploration, particularly advancements in spacesuit and rocket technology that will enable us to travel farther, faster, and safer than ever before. His work, though grounded on Earth, helps create the inspiration that fuels these bold endeavors.
“My hope for the next generation is that they dive deeper into their curiosity—exploring not only the world around them but also the Moon, planets, and beyond,” he said. “I also hope they carry forward the spirit of resilience and a commitment to making the world a better place for all.”
