NASA Test Deploys Roman Space Telescope Solar Panels, ‘Visor’
On Aug. 7 and 8, NASA’s Nancy Grace Roman Space Telescope team assessed the observatory’s solar panels and a visor-like sunshade called the deployable aperture cover — two components that will be stowed for launch and unfold in space. Engineers confirmed their successful operation during a closely monitored sequence in simulated space-like conditions. On the first day, Roman’s four outer solar panels were deployed one at a time, each unfolding over 30 seconds with 30-second pauses between them. The visor followed in a separate test the next day. These assessments help ensure Roman will perform as expected in space. Roman is slated to launch no later than May 2027, with the team working toward a potential early launch as soon as fall 2026.

Think of NASA’s Stennis Space Center, and one likely thinks of rocket propulsion testing. The site has a long history of testing to support the nation’s space efforts, including the current Artemis program to send astronauts to the Moon to prepare for future human exploration of Mars.
However, NASA Stennis also is working to become a key supporter of more terrestrial exploration. Indeed, in terms of unmanned range operations, NASA Stennis has it all – layers of restricted airspace, a closed canal system, and acres upon acres of protected terrain.

NASAThe NASA site near Bay St. Louis, Mississippi, is an ideal location for all types of air, marine, and ground testing, said Range Operations Manager Jason Peterson. “My job is to understand the customer, and their requirements and limitations, to help them succeed,” he added. “What makes NASA Stennis unique is our federally protected area for users to operate.”
The need to learn about unmanned systems, such as drones or underwater vehicles, in a safe environment is growing as technology advances. Think of it like learning to drive a car in a parking lot before hitting the road.
NASA Stennis has already begun leveraging these capabilities. In 2024, the center established an agreement with Skydweller Aero Inc. to utilize restricted airspace for flight testing of autonomous, solar-powered aircraft. This first-of-its-kind agreement paves the way for future collaborations as NASA Stennis expands its customer-based operations beyond onsite tenants.

NASA Stennis has its own protected airspace, similar to how airports control the skies around them. The Federal Aviation Administration (FAA) first established this restricted airspace in 1966 and expanded it in 2016 to support both NASA missions and U.S. Department of Defense operations.
NASA Stennis is one of only two non-military restricted airspaces in the nation. It operates two main airspace zones – a propulsion testing area extending from ground level up to 12,000 feet for safely testing rocket engines without interfering with regular air traffic, and an aircraft operations zone covering 100 square miles up to 6,000 feet, with 15 dedicated acres for drone launch and recovery.
NASA Stennis staff provide comprehensive support including safety reviews, coordination between aircraft operators and FAA air traffic controllers, and constant communication with range safety personnel to ensure all operations are conducted safely.
Marine OperationsThe centerpiece of the NASA Stennis marine range is its extensive 7.5-mile canal system, protected by a lock-and-dam system that connects to Pearl River tributaries. This network accommodates various marine platforms including traditional watercraft, autonomous underwater vehicles, remotely operated vehicles, unmanned surface vessels, and aerial drones requiring water landing capabilities.
The controlled environment provides protection from adverse weather and interference, making it ideal for testing sensitive or proprietary technologies. The facility is particularly valuable for emerging technologies in autonomous systems, sensor integration, and multi-domain operations where air, surface, and underwater platforms operate in coordination.
Ground LevelNASA Stennis facilities are located on 13,800 acres of fenced-in property, surrounded by an additional 125,000 acres of protected land known as the acoustical buffer zone. This area was established primarily through permanent lease to allow testing of large rocket hardware without disturbing area residents and is closely monitored without permanent habitable structures.
“The location helps reduce hazards to the public when testing new technology,” Peterson said. “With supporting infrastructure for office space, storage, or manufacturing, this makes NASA Stennis a great place to test, train, operate, and even manufacture.”
The NASA Stennis federal city already hosts more than 50 federal, state, academic, public, and private aerospace, technology, and research organizations, with room for more. All tenants share operating costs while pursuing individual missions.
‘Open for Business’NASA Stennis leaders are keenly aware of the opportunity such unique capabilities afford. The center’s 2024-2028 strategic plan states NASA Stennis will leverage these unique capabilities to support testing and operation of uncrewed systems.
Leaders are working to identify opportunities to maximize site capabilities and develop an effective business model. “NASA Stennis is open for business, and we want to provide a user-friendly range for operators to test vehicles by creating an environment that is safe, cost-effective, and focused on mission success,” Peterson said.

Curiosity Blog, Sols 4638-4640: Imaging Extravaganza Atop a Ridge NASA’s Mars rover Curiosity acquired this image on Aug. 21, 2025, looking across the ridge that the rover is currently parked near the edge of, looking down into the “Thumb” region that mission planners hope to be exploring next week. Curiosity captured this image using its Left Navigation Camera on Sol 4636, or Martian day 4,636 of the MArs Science Laboratory mission, at 16:09:13 UTC.NASA/JPL-Caltech

Earth planning date: Friday, Aug. 22, 2025
Curiosity is continuing its winding path through the mysterious boxwork structures that have been a major focus of the last several months of the mission. After driving away from “Río Frío,” we are now parked on top of a ridge overlooking a topographic depression that we’ve nicknamed the “Thumb.” The image on this post shows that ridge running along the “thumb’s” edge. Our goal today is to characterize this ridge before we drive down into the Thumb.
Because we had a lot of power and three sols available to play around with, this weekend plan is packed with a lot of good science. The boxwork structures in our immediate vicinity get a lot of attention, with Mastcam images planned of the targets “Wallatiri,” “Wallatiri 2,” “Mojo,” “Samaipata,” “Fort Samaipata,” and “Río Lluta,” as well as a nearby trough. ChemCam will be taking LIBS measurements of both Samaipata and Fort Saaipata as well. Samaipata gets even more attention from MAHLI, in addition to the targets “Vitichi” and “Tartagalita,” both of which will also be observed by APXS.
The boxwork structures don’t get all of the fun today, though. In addition to all of the boxwork observations, Mastcam will be documenting the ChemCam AEGIS target from Monday’s plan, and will also be doing some more imaging of the “Mishe Mokwa” butte. The highlight of Mastcam’s work in this plan (at least in my opinion) is the large 44-image mosaic of the north crater rim, taking advantage of the particularly low dust content of the atmosphere at this time of year. ChemCam will be taking several RMI images of Mishe Mokwa and a distant outcrop at “Dragones” that we will be driving towards over the next several months, as well as the usual post-drive AEGIS.
Rounding out this plan is a collection of observations of the atmosphere. In addition to typical DAN, REMS, and RAD activities, Curiosity’s Navcams will be put to work with a dust-devil movie, dust-devil survey, five cloud movies, and two line-of-sight observations of the north crater rim. Mastcam also gets involved in the environmental fun with a tau to track the amount of dust in the air.
Even with all of these activities, we decided that we aren’t yet done with this area. The drive in today’s plan is a short bump of about 2 meters (about 6.6 feet), so we’re all looking forward to continuing our investigation of this ridge on Monday.

Uranus' 29th Moon Can't Hide From The JWST
The JWST has found another moon orbiting Uranus. It's the planet's 29th known moon, and it bears the uninspiring, temporary name S/2025 U1. It's too small and faint to be detected by the Hubble, or by Voyager 2, the only spacecraft to visit the ice giant.
The Stunning Astrogeology of the Apollo Missions
Neil Armstrong almost made a mistake. He had found an interesting rock sticking out of a formation. Curious to see what the rock was made of, he needed to examine its interior more closely. So he reached for his hammer and took a swing.
Sensors Could Permanently Fly In The "Ignorosphere" Using Novel Propulsion Technique
Earth’s atmosphere is large, extending out to around 10,000 km from the surface of the planet. It’s so large, in fact, that scientists break it into five separate sections, and there’s one particular section that hasn’t got a whole lot of attention due to the difficulty in keeping any craft afloat there. Planes and balloons can visit the troposphere and stratosphere, the two sections closest to the ground, while satellites can sit in orbit in the thermosphere and exosphere, allowing for a platform for consistent observations. But the mesosphere, the section in the middle, is too close to have a stable orbit, but too sparse in air for traditional airplanes or balloons to work. As a result, we don’t have a lot of data on it, but it impacts climate and weather forecasting, so scientists have simply had to make a lot of assumptions about what it's like up there. But a new study from researchers at Harvard and the University of Chicago might have found a way to put stable sensing platforms into the mesosphere, using a novel flight mechanism known as photophoresis.
