NASA’s Psyche Spacecraft Reignites Thrusters After Switching to Backup Mode

Ars Technica reports, “A NASA spacecraft bound for an unexplored metal-rich asteroid has reignited its plasma thrusters, continuing its cruise deeper into the Solar System after switching to a backup fuel line. The $1.4 billion Psyche mission, built to explore an asteroid with the same name, has four electric thrusters fueled by xenon gas. Psyche’s solar-electric propulsion system is more fuel-efficient than conventional rocket thrusters, and it works by flowing xenon through an electromagnetic field, which ionizes the gas and expels the ions at high speed to produce thrust.”

Airbus’ Racer Rotorcraft Achieves Speed Target

Aviation Week reports, “Airbus Helicopters has achieved its speed target with its Racer compound rotorcraft, successfully flying the experimental aircraft at 240 kt. (276 mph) in April. The aircraft reached the speed with power margin to spare, test pilots say, and after only 25 flying hours—one-eighth of the flying hours that have been “justified” for the flight-test program—which points to the maturity of the aircraft’s design.”

Sat Tracking Firms Say Chinese Satellite Appears to be Trying First-ever On-orbit Refueling

Breaking Defense reports, “A Chinese satellite designed for refueling missions has been dancing awfully close to another Chinese bird in orbit, raising the possibility Beijing is about to pull off — or already has pulled off — the first-ever on-orbit gas-up, according to satellite tracking firms. Last week Slingshot Aerospace watched China’s experimental SJ-25, which Beijing launched in January and has said publicly was meant for refueling missions, approach another satellite, SJ-21. But the view from terrestrial telescopes wasn’t able to confirm docking, much less refueling, so Slingshot concluded the data was ‘inconclusive’ as to what exactly happened.”

SpaceX Starship Upper Stage Explodes While Being Prepped for Next Engine Test Firing

CBS News reports a SpaceX Starship upper stage exploded in a spectacular conflagration during ramp-up to an expected engine test firing at the company’s Starbase manufacturing facility on the Texas Gulf Coast late Wednesday, destroying the rocket in what appears to be a major setback for the Super Heavy-Starship vehicle Elon Musk says is critical to the company’s future. “Video from LabPadre, a company that monitors SpaceX activities at Starbase, showed the Starship suddenly exploding in a huge fireball just after 11 p.m. CDT, 10 to 15 minutes before the anticipated engine test firing,” sending flaming debris shooting away into the overnight sky from a churning fireball that engulfed the test stand.

NASA Chief Says X-59 Will Still Play Key Role in Return to Supersonic Flight

Aviation Week reports, “The X-59 low boom demonstrator remains highly relevant, says NASA’s acting administrator. Although running years behind its original schedule, the NASA aircraft is still expected to play a key role in helping ICAO and the FAA develop a noise certification standard for sonic booms that could clear the way for legal overland civil fight at higher supersonic speeds.”

Greek Entrepreneur Hopes to Build Giant Net to Catch Incoming Cargo on the Moon

SPACE reports, “Greece-based entrepreneur has a unique idea for moon-bound deliveries: using a giant net to catch packages launched from lunar orbit. Although there are still many hurdles to clear, the system would address many of the key challenges for moon-bound deliveries and could aid in the future mining of lunar resources. Right now, lunar landers are costly, especially when they fail. Rather than using landers for deliveries to the moon’s surface, Charis Kosmas has developed a concept called the Momentum Absorption Catcher for Express Deliveries on Non-Atmospheric Somata (MACEDONAS).”
