Technicians have successfully installed two sunshields onto NASA’s Nancy Grace Roman Space Telescope’s inner segment. Along with the observatory’s Solar Array Sun Shield and Deployable Aperture Cover, the panels (together called the Lower Instrument Sun Shade), will play a critical role in keeping Roman’s instruments cool and stable as the mission explores the infrared universe.

“This shield is like an extremely strong sunblock for Roman’s sensitive instruments, protecting them from heat and light from the Sun that would otherwise overwhelm our ability to detect faint signals from space,” said Matthew Stephens, an aerospace engineer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
The sunshade, which was designed and engineered at NASA Goddard, is essentially an extension of Roman’s solar panels, except without solar cells. Each sunshade flap is roughly the size of a garage door — about 7 by 7 feet (2.1 by 2.1 meters) — and 3 inches (7.6 centimeters) thick.
“They’re basically giant aluminum sandwiches, with metal sheets as thin as a credit card on the top and bottom and the central portion made up of a honeycomb structure,” said Conrad Mason, an aerospace engineer at NASA Goddard.
This design makes the panels lightweight yet stiff, and the material helps limit heat transfer from the side facing the Sun to the back—no small feat considering the front will be hot enough to boil water (up to 216 degrees Fahrenheit, or 102 degrees Celsius) while the back will be much colder than Antarctica’s harshest winter (minus 211 Fahrenheit, or minus 135 Celsius). A specialized polymer film blanket will wrap around each panel to temper the heat, with 17 layers on the Sun side and one on the shaded side.
The sunshade will be stowed and gently deploy around an hour after launch.

The test helps verify the panels will operate as designed in space.NASA/Sophia Roberts “The deploying mechanisms have dampers that work like soft-close hinges for drawers or cabinets, so the panels won’t slam open and rattle the observatory,” Stephens said. “They each take about two minutes to move into their final positions. This is the very first system that Roman will deploy in space after the spacecraft separates from the launch vehicle.”
Now completely assembled, Roman’s inner segment is slated to undergo a 70-day thermal vacuum test next. Engineers and scientists will test the full functionality of the spacecraft, telescope, and instruments under simulated space conditions. Following the test, the sunshade will be temporarily removed while the team joins Roman’s outer and inner assemblies, and then reattached to complete the observatory. The mission remains on track for launch no later than May 2027 with the team aiming for as early as fall 2026.

After months of work in the NASA Spacesuit User Interface Technologies for Students (SUITS) challenge, more than 100 students from 12 universities across the United States traveled to NASA’s Johnson Space Center in Houston to showcase potential user interface designs for future generations of spacesuits and rovers.
NASA Johnson’s simulated Moon and Mars surface, called “the rock yard,” became the students’ testing ground as they braved the humid nights and abundance of mosquitoes to put their innovative designs to the test. Geraldo Cisneros, the tech team lead, said, “This year’s SUITS challenge was a complete success. It provided a unique opportunity for NASA to evaluate the software designs and tools developed by the student teams, and to explore how similar innovations could contribute to future, human-centered Artemis missions. My favorite part of the challenge was watching how the students responded to obstacles and setbacks. Their resilience and determination were truly inspiring.”
Tess Caswell and the Rice Owls team from Rice University test their augmented reality heads-up display at Johnson Space Center’s Rock Yard in Houston on May 19, 2025.NASA/James Blair Students filled their jam-packed days not only with testing, but also with guest speakers and tours. Swastik Patel from Purdue University said, “All of the teams really enjoyed being here, seeing NASA facilities, and developing their knowledge with NASA coordinators and teams from across the nation. Despite the challenges, the camaraderie between all the participants and staff was very helpful in terms of getting through the intensity. Can’t wait to be back next year!”
John Mulnix with Team Cosmoshox from Wichita State University presents the team’s design during the Spacesuit User Interface Technologies for Students (SUITS) exit pitches at Johnson on May 22, 2025.NASA/David DeHoyos “This week has been an incredible opportunity. Just seeing the energy and everything that’s going on here was incredible. This week has really made me reevaluate a lot of things that I shoved aside. I’m grateful to NASA for having this opportunity, and hopefully we can continue to have these opportunities.”
At the end of test week, each student team presented their projects to a panel of experts. These presentations served as a platform for students to showcase not only their technical achievements but also their problem-solving approaches, teamwork, and vision for real-world application. The panel–composed of NASA astronaut Deniz Burnham, Flight Director Garrett Hehn, and industry leaders–posed thought-provoking questions and offered constructive feedback that challenged the students to think critically and further refine their ideas. Their insights highlighted potential areas for growth, new directions for exploration, and ways to enhance the impact of their projects. The students left the session energized and inspired, brimming with new ideas and a renewed enthusiasm for future development and innovation. Burnham remarked, “The students did such a great job. They’re all so creative and wonderful, definitely something that can be implemented in the future.”

An artist’s concept of the Starlab commercial space station.Starlab As NASA continues its transition toward a commercial low Earth orbit marketplace, an agency-supported commercial space station, Starlab, recently completed five development and design milestones. Starlab’s planned design consists of a service module and a habitat that will be launched to orbit on a single flight.
The milestones, part of a NASA Space Act Agreement awarded in 2021, focused on reviews of Starlab’s preliminary design and safety, as well as spacecraft mockup and procurement plans. Each milestone provides NASA insight into the company’s development progress.
“As we work toward the future of low Earth orbit, these milestones demonstrate Starlab’s dedication to building a commercial space station that can support human life and advance scientific research,” said Angela Hart, program manager for NASA’s Commercial Low Earth Orbit Development Program at the agency’s Johnson Space Center in Houston. “Both the insight shared by Starlab and the expertise shared by NASA are critical to future mission success.”
Starlab recently completed a preliminary design and safety review of its station’s architecture and systems. The company now will begin detailed design and hardware development, culminating in a critical design review later this year. Critical design reviews are an important step in a station’s development, assessing design maturity before proceeding with fabrication and assembly.
An artist’s concept of the Starlab commercial space station.Starlab Starlab also has begun construction of a full-scale, high-fidelity mockup of the station. The mockup, which will be housed in the Space Vehicle Mockup Facility at NASA Johnson, will be used for human-in-the-loop testing, during which participants perform day-in-the-life walkthroughs and evaluate the interior design, crew training, procedure development, hardware checks, and in-flight issue resolution.
In addition, Starlab completed reviews of the system design architecture, procurement plan, and Northrop Grumman Cygnus spacecraft docking system design. In 2023, Northrop Grumman teamed up with Starlab to provide cargo logistics services and engineering consultation to support the commercial space station. These reviews included design configuration updates of solar arrays, docking ports, crew quarters, and more.
NASA supports the design and development of multiple commercial space stations through funded and unfunded agreements. Following the design and development phase, NASA plans to procure services from one or more companies as part of its strategy to become one of many customers for low Earth orbit stations.

NASA Jet Propulsion Laboratory
The goal of this effort is to develop a robust and affordable mission architecture that enables the gravimetric density reconstruction of small body interiors to unprecedented precision. Our architecture relies on the novel concept of “Gravity Poppers,” which are small, minimalistic probes that are deployed to the surface of a small body and periodically “pop” so as to perpetuate a random hopping motion around the body. By tracking a large swarm of poppers from orbit, a mother spacecraft can precisely estimate their trajectories and continuously refine a high-resolution map of the body’s gravity field, and thus, its internal mass distribution. Hopping probes are also equipped with minimalistic in-situ sensors to measure the surface temperature (when landed) and strength (when bouncing) in order to complement the gravity field and build a more accurate picture of the interior. The Phase I study focused on feasibility assessment of three core technologies that enable such a mission: (1) the mechanical design of hopping probes to be small, simple, robust, and “visible” to a distant spacecraft, (2) the tracking strategy for detecting and estimating the trajectories of a large number of ballistic probes, and (3) the algorithmic framework by which such measurements can be used to iteratively refine a gravity model of the body. The key finding was that the concept is feasible, and demonstrated to have the potential to resolve extremely accurate gravity models, allowing scientists to localize density anomalies such as “weighing” large boulders on the surface. This Phase II Proposal aims to further develop these three core technologies through continued mission trade studies and sensitivity analysis, case studies for simulated missions, and hardware prototypes demonstrating both hopping behavior and tracking performance.
