4 Min Read Science Meets Art: NASA Astronaut Don Pettit Turns the Camera on Science
NASA astronaut Don Pettit is scheduled to return home in mid-April after a seven-month mission aboard the International Space Station as part of Expedition 72. Throughout his stay, Pettit contributed to research that benefits humanity and future space missions.
Pettit also shared what he calls “science of opportunity” to demonstrate how experimenting with our surroundings can help gain a better understanding of how things work. This understanding is perhaps enhanced when art, science, and microgravity come together.
Electrostatic Displays
NASA astronaut Don Pettit demonstrates electrostatic forces using charged water droplets and a knitting needle made of Teflon. This series of overlapping frames displays the unique attraction-repulsion properties of Teflon and charged droplets, similar to how charged particles from the Sun behave when they come in contact with Earth’s magnetic field. Highly energetic particles from space that collide with atoms and molecules in the atmosphere create the aurora borealis.
Specialized Equipment for Superb Science
NASA astronaut Don Pettit snaps an image of the hands of NASA astronauts Nick Hague, left, and Suni Williams inside the Life Science Glovebox, a facility at the International Space Station that separates the science from the scientists, thus protecting both from contamination.
The freezers on the International Space Station are as crucial as its experiment modules, preserving samples for further analysis on Earth. The Minus Eighty-Degree Laboratory Freezer for International Space Station stores samples at ultra-cold temperatures. NASA astronaut Don Pettit used it to freeze thin ice wafers, which he photographed with a polarizing filter to reveal unique crystal structures.
New Tech Roll-Out
NASA astronaut Don Pettit films a time-lapse sequence of Canadarm2 retrieving Materials International Space Station Experiment (MISSE-20-Commercial) samples at the International Space Station. This investigation exposed various experiments to the harsh space environment, such as vacuum, radiation, and extreme temperatures. Findings could help in many areas, from designing more durable materials to advancing quantum communications.
A surge in International Space Station research supports NASA’s exploration efforts at the Moon and beyond, requiring more energy to operate the orbiting laboratory. NASA astronaut Don Pettit photographs new and old solar arrays side by side. The technology used by the International Space Station Roll-Out Solar Arrays (IROSA) on the right was first tested aboard the station in 2017. By 2023, six IROSAs were deployed aboard station, providing a 20-30% increase in power for research and operations. Roll-Out Solar Arrays were also used on NASA’s DART asteroid mission and now are slated for the Gateway lunar outpost, a vital component of Artemis.
Squire for Spacewalks
I am the nameless boy who stays in the confines of the tent helping the Knights suit up for battle. I remain in the airlock, preparing these knights for a walk outside.

NASA astronaut Don Pettit helped his colleagues suit up for two spacewalks in January. The first spacewalk involved patching the Neutron Star Interior Composition Explorer (NICER), a telescope that measures X-rays from neutron stars and other cosmic objects. Sunlight interference affected data collection, and the patches reduced this issue. On the second spacewalk, astronauts collected samples from the exterior of the International Space Station for ISS External Microorganisms. This investigation examines whether the orbiting laboratory releases microbes, how many, and how far these may travel. Findings could inform the design of future spacecraft, including spacesuits, to limit biocontamination during future space missions.
Photography with a Spin
NASA astronaut Don Pettit photographs “cosmic colors at sunrise.” From 250 miles above, the International Space Station’s orbital path covers most of Earth’s population, offering valuable data and a great opportunity for shooting breathtaking photography.
NASA astronaut Don Pettit leveraged his stay aboard the International Space Station to photograph our planet with an artistic twist.
NASA astronaut Don Pettit wrote on social media about his snapshot of the Mediterranean Sea from the International Space Station, “Sun glint off the Mediterranean Sea (infrared and converted to black and white). When the Sun reflects off the ocean, watery details unseen with normal lighting appear. Small centimeter differences in ocean height become visible, revealing hidden currents.”
NASA astronaut Don Pettit’s photography could contribute to the study of transient luminous events, colorful electrical discharges that occur above thunderstorms. His imagery can be paired with data from the Atmosphere-Space Interactions Monitor (ASIM) and Thor-Davis, a high-speed thunderstorm camera. The combined efforts of crew photography and instruments aboard the International Space Station help scientists better understand thunderstorms and their impacts on Earth’s upper atmosphere.
More of Pettit’s photography can be found on his X profile, @astro_Pettit.

In an open challenge, NASA is seeking innovative business models that propose new approaches to solving complex Earth science problems using unconventional computing methods and is holding an informational webinar on Monday, April 28.
The agency’s Beyond the Algorithm Challenge, sponsored by NASA’s Earth Science Technology Office, asks for proposals to more rapidly and accurately understand our home planet using transformative computing methods such as quantum computing, quantum machine learning, neuromorphic computing, in-memory computing, or other approaches.
The Beyond the Algorithm Challenge kicked off in March and consists of three phases. Participant submissions, which are due on July 25, will be evaluated based on creativity, technical feasibility, impact, business model evaluation, and presentation. Up to 10 finalists will be invited to present their ideas to a panel of judges at a live pitch event, and winners will a monetary prize.
For details about the challenge, interested participants can sign up for the informational webinar on Monday, April 28, here.
Using the vantage point of space, NASA’s observations of Earth increase our understanding of our home planet, improve lives, and safeguard our future. The capabilities of NASA’s Earth Science Division include developing new technology, delivering actionable science, and providing environmental information to meet the increased demand for more sophisticated, more accurate, more trustworthy, and more actionable environmental information for decision-makers and policymakers.
For example, rapid flood analysis is one area that may benefit from computing advancements. Flood hazards affect personal safety and land use, directly affecting individual livelihoods, community property, and infrastructure development and resilience. Advanced flood analysis capability enables contributions to protect and serve impacted communities, making a tangible difference in areas such as disaster preparedness, recovery, and resilience.
Advancements in computing capabilities show promise in overcoming processing power, efficiency, and performance limitations of conventional computing methods in addressing Earth science challenges like rapid flood analysis. Quantum computers offer a fundamentally different paradigm of computation and can solve certain classes of problems exponentially faster than their classical counterparts. Likewise, quantum machine learning offers the potential to reduce required training data or produce more accurate models. The emerging field of neuromorphic, or brain-inspired, computing holds significant promise for algorithm development optimized for high-speed, low power. And in-memory computing saves time and energy for data-heavy processes like artificial intelligence training.
Blue Clarity is hosting the Beyond the Algorithm Challenge on behalf of NASA. The NASA Tournament Lab, part of the Prizes, Challenges, and Crowdsourcing program in the Space Technology Mission Directorate, manages the challenge. The program supports global public competitions and crowdsourcing as tools to advance NASA research and development and other mission needs.

GLOBE Mission Earth Supports Career Technical Education
The NASA Science Activation program’s GLOBE Mission EARTH (GME) project is forging powerful connections between career technical education (CTE) programs and real-world science, inspiring students across the United States to pursue careers in Science, Technology, Engineering, and Mathematics (STEM).
GME is a collaborative effort between NASA scientists, educators, and schools that brings NASA Earth science and the GLOBE Program into classrooms to support hands-on, inquiry-based learning. GLOBE (Global Learning and Observations to Benefit the Environment) is an international science and education program that provides students and the public with the opportunity to participate in data collection and the scientific process, contributing meaningfully to our understanding of the Earth system.
By connecting students directly to environmental research and NASA data, GME helps make science more relevant, engaging, and applicable to students’ futures. In CTE programs—where project-based and work-based learning are key instructional strategies—GME’s integration of GLOBE protocols offers students the chance to develop not only technical skills, but also essential data literacy and professional competencies like collaboration, critical thinking, and communication. These cross-cutting skills are valuable across a wide range of industries, from agriculture and advanced manufacturing to natural resources and public safety.
The real-world, hands-on approach of CTE makes it an ideal setting for implementing GLOBE to support STEM learning across industries. At Skyline High School in Oakland, California, for example, GLOBE has been embedded in multiple courses within the school’s Green Energy Pathway, originally launched by GLOBE partner Tracy Ostrom. Over the past decade, nearly 1,000 students have participated in GLOBE activities at Skyline. Many of these students describe their experiences with environmental data collection and interactions with NASA scientists as inspiring and transformative. Similarly, at Toledo Technology Academy, GME is connecting students with NASA science and renewable energy projects—allowing them to study how solar panels impact their local environment and how weather conditions affect wind energy generation.
To expand awareness of how GLOBE can enhance CTE learning and career preparation, WestEd staff Svetlana Darche and Nico Janik presented at the Educating for Careers Conference on March 3, 2025, in Sacramento, California. This event, sponsored by the California chapter of the Association for Career and Technical Education (ACTE), brought together over 2,600 educators dedicated to equipping students with the tools they need to succeed in an evolving job market. Darche and Janik’s session, titled “Developing STEM Skills While Contributing to Science,” showcased GLOBE’s role in work-based learning and introduced new federal definitions from the Carl D. Perkins Act (Perkins V) that emphasize:
Interactions with industry professionals A direct link to curriculum and instruction First-hand engagement with real-world tasks in a given career field GLOBE’s approach to scientific data collection aligns perfectly with these criteria. Janik led 40 educators through a hands-on experience using the GLOBE Surface Temperature Protocol, demonstrating how students investigate the Urban Heat Island Effect while learning critical technical and analytical skills. By collecting and analyzing real-world data, students gain firsthand experience with the tools and methods used by scientists, bridging the gap between classroom learning and future career opportunities.
Through GME’s work with CTE programs, students are not only learning science—they are doing science. These authentic experiences inspire, empower, and prepare students for careers where data literacy, scientific inquiry, and problem-solving are essential. With ongoing collaborations between GLOBE, NASA, and educators nationwide, the next generation of STEM professionals is already taking shape—one real-world investigation at a time.
GME is supported by NASA under cooperative agreement award number NNX16AC54A and is part of NASA’s Science Activation Portfolio.
