Engineers Conduct First In-Orbit Test of ‘Swarm’ Satellite Autonomous Navigation

With 2D cameras and space robotics algorithms, astronautics engineers have created a navigation system able to manage multiple satellites using visual data only. They just tested it in space for the first time.

Someday, instead of large, expensive individual space satellites, teams of smaller satellites — known by scientists as a “swarm” — will work in collaboration, enabling greater accuracy, agility, and autonomy. Among the scientists working to make these teams a reality are researchers at Stanford University’s Space Rendezvous Lab, who recently completed the first-ever in-orbit test of a prototype system able to navigate a swarm of satellites using only visual information shared through a wireless network.

“It’s a milestone paper and the culmination of 11 years of effort by ...

SwRI-led team finds Evidence of Hydration on Asteroid Psyche

Computer generated image of Psyche asteroid impact
Courtesy of SwRI An SwRI-led team used NASA’s Webb telescope, shown in the bottom right corner of this illustration, to confirm the presence of hydrated minerals on the surface of Psyche, a massive and heavily metallic body in the main asteroid belt. These findings suggest a complex history for this interesting asteroid, which many scientists think could be the remnant core of a protoplanet, including impacts with hydrated asteroids.

Webb telescope data indicate a complex history for the metallic asteroid. Using data from NASA’s James Webb Space Telescope, a Southwest Research Institute-led team has confirmed hydroxyl molecules on the surface of the metallic asteroid Psyche...

Scientists Find Oceans of Water on Mars. It’s just Too Deep to Tap.

The top 5 kilometers of the crust appear to be dry, but a new study provides evidence for a zone of fractured rock 11.5-20 km below the surface that is full of liquid water — more than the volume proposed to have filled hypothesized ancient Martian oceans.

Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water—enough to fill oceans on the planet’s surface.

The data from NASA’s Insight lander allowed the scientists to estimate that the amount of groundwater could cover the entire planet to a depth of between 1 and 2 kilometers, or about a mile.

A ‘FURST’ of its Kind: Sounding Rocket Mission to Study Sun as a Star

1. The Full-sun Ultraviolet Rocket SpecTrograph (FURST) undergoes testing at White Sands Missile Range in New Mexico in preparation for launch on Aug. 11. FURST will be launched aboard a Black Bryant IX sounding rocket and will observe the Sun in vacuum ultraviolet (VUV). The instrument was designed and built at Montana State University.
