Preparations for Next Moonwalk Simulations Underway (and Underwater)
Eric Garza, an engineering technician in the Experimental Fabrication Shop at NASA’s Armstrong Flight Research Center in Edwards, California, cuts plywood to size for temporary floorboards for the X-66 experimental demonstrator aircraft on Aug. 26, 2024.NASA/Steve Freeman NASA designed temporary floorboards for the MD-90 aircraft to use while it is transformed into the X-66 experimental demonstrator aircraft. These floorboards will protect the original flooring and streamline the modification process.
Supporting the agency’s Sustainable Flight Demonstrator project, a small team in the Experimental Fabrication Shop at NASA’s Armstrong Flight Research Center in Edwards, California, built temporary floorboards to save the project time and resources. Repeated removal and installation of the original flooring during the modification process was time-consuming. Using temporary panels also ensures the original floorboards are protected and remain flightworthy for when modifications are complete, and the original flooring is reinstalled.
“The task of creating the temporary floorboards for the MD-90 involves a meticulous process aimed at facilitating modifications while maintaining safety and efficiency. The need for these temporary floorboards arises from the detailed procedure required to remove and reinstall the Original Equipment Manufacturer (OEM) floorboards,” said Jason Nelson, experimental fabrication lead. He is one of two members of the fabrication team – one engineering technician and one inspector – manufacturing about 50 temporary floorboards, which range in size from 20 inches by 36 inches to 42 inches by 75 inches.

The flooring was designed for the X-66 experimental demonstrator aircraft. NASA/Steve Freeman Nelson continued, “Since these OEM boards will be removed and reinstalled multiple times to accommodate necessary modifications, the temporary floorboards will save the team valuable time and resources. They will also provide the same level of safety and strength as the OEM boards, ensuring that the process runs smoothly without compromising quality.”
Designing and prototyping the flooring was a meticulous process, but the temporary solution plays a crucial role in optimizing time and resources as NASA works to advance safe and efficient air travel. The agency’s Sustainable Flight Demonstrator project seeks to inform the next generation of single-aisle airliners, the most common aircraft in commercial aviation fleets around the world. NASA partnered with Boeing to develop the X-66 experimental demonstrator aircraft.
NASA Armstrong’s Experimental Fabrication Shop carries out modifications and repair work on aircraft, ranging from the creation of something as small as an aluminum bracket to modifying wing spars, fuselage ribs, control surfaces, and other tasks to support missions.

Visiting Mars on the Way to the Outer Solar System
Written by Roger Wiens, Principal Investigator, SuperCam instrument / Co-Investigator, SHERLOC instrument at Purdue University
A portion of the “Sally’s Cove” outcrop where the Perseverance rover has been exploring. The radiating lines in the rock on the left of the image may indicate that it is a shatter cone, showing the effects of the shock wave from a nearby large impact. The image was taken by Mastcam-Z’s left camera on March 21, 2025 (Sol 1452, or Martian day 1,452 of the Mars 2020 mission) at the local mean solar time of 12:13:44. Mastcam-Z is a pair of cameras located high on the rover’s mast. This image was voted by the public as “Image of the week.” NASA/JPL-Caltech/ASU Recently Mars has had a few Earthly visitors. On March 1, NASA’s Europa Clipper flew within 550 miles (884 kilometers) of the Red Planet’s surface on its way out to Jupiter. On March 12, the European Space Agency’s Hera spacecraft flew within about 3,100 miles (5,000 kilometers) of Mars, and only 300 kilometers from its moon, Deimos. Hera is on its way to study the binary asteroid Didymos and its moon Dimorphos. Next year, in May 2026, NASA’s Psyche mission is scheduled to buzz the Red Planet on its way to the metal-rich asteroid 16 Psyche, coming within a few thousand kilometers.
Why all these visits to Mars? You might at first think that they’re using Mars as an object of opportunity for their cameras, and you would be partially right. But Mars has more to give these missions than that. The main reason for these flybys is the extra speed that Mars’ velocity around the Sun can give them. The idea that visiting a planet can speed up a spacecraft is not all that obvious, because the same gravity that attracts the spacecraft on its way towards the planet will exert a backwards force as the spacecraft leaves the planet.
The key is in the direction that it approaches and leaves the planet. If the spacecraft leaves Mars heading in the direction that Mars is traveling around the Sun, it will gain speed in that direction, slingshotting it farther into the outer solar system. A spacecraft can typically gain several percent of its speed by performing such a slingshot flyby. The closer it gets to the planet, the bigger the effect. However, no mission wants to be slowed by the upper atmosphere, so several hundred kilometers is the closest that a mission should go. And the proximity to the planet is also affected by the exact direction the spacecraft needs to go when it leaves Mars.
Clipper’s Mars flyby was a slight exception, slowing down the craft — by about 1.2 miles per second (2 kilometers per second) — to steer it toward Earth for a second gravity assist in December 2026. That will push the spacecraft the rest of the way to Jupiter, for its 2030 arrival.
While observing Mars is not the main reason for their visits, many of the visiting spacecraft take the opportunity to use their cameras either to perform calibrations or to study the Red Planet and its moons.
During Clipper’s flyby over sols 1431-1432, Mastcam-Z was directed to watch the skies for signs of the interplanetary visitor. Clipper’s relatively large solar panels could have reflected enough sunlight for it to be seen in the Mars night sky, much as we can see satellites overhead from Earth. Unfortunately, the spacecraft entered the shadow of Mars just before it came into potential view above the horizon from Perseverance’s vantage point, so the sighting did not happen. But it was worth a try.
Meanwhile, back on the ground, Perseverance is performing something of a cliff-hanger. “Sally’s Cove” is a relatively steep rock outcrop in the outer portion of Jezero crater’s rim just north of “Broom Hill.” Perseverance made an approach during March 19-23, and has been exploring some dark-colored rocks along this outcrop, leaving the spherules behind for the moment. Who knows what Perseverance will find next?

How can I see the northern lights?
To see the northern lights, you need to be in the right place at the right time.
Auroras are the result of charged particles and magnetism from the Sun called space weather dancing with the Earth’s magnetic field. And they happen far above the clouds. So you need clear skies, good space weather at your latitude and the higher, more polar you can be, the better. You need a lot of patience and some luck is always helpful.
A smartphone can also really help confirm whether you saw a little bit of kind of dim aurora, because cameras are more sensitive than our eyes.
The best months to see aurorae, statistically, are March and September. The best times to be looking are around midnight, but sometimes when the Sun is super active, it can happen any time from sunset to sunrise.
You can also increase your chances by learning more about space weather data and a great place to do that is at the NOAA Space Weather Prediction Center.
You can also check out my project, Aurorasaurus.org, where we have free alerts that are based on your location and we offer information about how to interpret the data. And you can also report and tell us if you were able to see aurora or not and that helps others.
One last tip is finding a safe, dark sky viewing location with a great view of the northern horizon that’s near you.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A NASA F/A-18 research aircraft flies above California near NASA’s Armstrong Flight Research Center in Edwards, California, testing a commercial precision landing technology for future space missions. The Psionic Space Navigation Doppler Lidar (PSNDL) system is installed in a pod located under the right wing of the aircraft.NASA Nestled in a pod under an F/A-18 Hornet aircraft wing, flying above California, and traveling up to the speed of sound, NASA put a commercial sensor technology to the test. The flight tests demonstrated the sensor accuracy and navigation precision in challenging conditions, helping prepare the technology to land robots and astronauts on the Moon and Mars.
The Psionic Space Navigation Doppler Lidar (PSNDL) system is rooted in NASA technology that Psionic, Inc. of Hampton, Virginia, licensed and further developed. They miniaturized the NASA technology, added further functionality, and incorporated component redundancies that make it more rugged for spaceflight. The PSNDL navigation system also includes cameras and an inertial measurement unit to make it a complete navigation system capable of accurately determining a vehicle’s position and velocity for precision landing and other spaceflight applications.
NASA engineers and technicians install the Psionic Space Navigation Doppler Lidar (PSNDL) system into a testing pod on a NASA F/A-18 research aircraft ahead of February 2025 flight tests at NASA’s Armstrong Flight Research Center in Edwards, California.NASA The aircraft departed from NASA’s Armstrong Flight Research Center in Edwards, California, and conducted a variety of flight paths over several days in February 2025. It flew a large figure-8 loop and conducted several highly dynamic maneuvers over Death Valley, California, to collect navigation data at various altitudes, velocities, and orientations relevant for lunar and Mars entry and descent. Refurbished for these tests, the NASA F/A-18 pod can support critical data collection for other technologies and users at a low cost.
Doppler Lidar sensors provide a highly accurate measurement of speed by measuring the frequency shift between laser light emitted from the sensor reflected from the ground. Lidar are extremely useful in sunlight-challenged areas that may have long shadows and stark contrasts, such as the lunar South Pole. Pairing PSNDL with cameras adds the ability to visually compare pictures with surface reconnaissance maps of rocky terrain and navigate to landing at interesting locations on Mars. All the data is fed into a computer to make quick, real-time decisions to enable precise touchdowns at safe locations.

The company has also tested PSNDL prototypes on suborbital vehicles via the Flight Opportunities program. In 2024, onboard a commercial lunar lander, NASA successfully demonstrated the predecessor NDL system developed by the agency’s Langley Research Center in Hampton, Virginia.
