Stuck propulsion valve delays second SLS test-firing
A troublesome liquid oxygen valve on the Space Launch System's first flight-rated core stage will keep NASA from performing a second test-firing of the rocket's four main engines this week.
Biden backs Artemis moon program; watchdog says it’ll cost $86 billion
The Biden administration supports continuing NASA’s Artemis program to return astronauts back to the moon, the White House said last week, without stating whether it will back away from the program’s already-in-doubt schedule for a lunar landing by the end of 2024.
SpaceX wins contract to launch first pieces of NASA’s Gateway lunar outpost
NASA announced Tuesday it has awarded SpaceX a $331 million contract to launch the first two pieces of the Gateway lunar outpost in 2024 using a modified version of the Falcon Heavy rocket to hurl the massive core of the deep space station toward the moon.
VideoSpaceX Starship prototype lost in test flight landing mishap
SpaceX launched a prototype Starship rocket Tuesday from its Boca Chica, Texas, flight facility, successfully sending the silver booster up to an altitude of about six miles as planned. But the unpiloted test flight ended with a spectacular explosion when the rocket failed to right itself and slow down enough for a tail-first landing.

Second high-altitude Starship test flight ends in landing explosion
Starship completed a successful climb to approximately 10 kilometers altitude and then descended horizontally toward the landing site. It appeared to lose control as it was in the process of flipping back to a vertical position and exploded as it bellyflopped onto the landing pad. Watch a replay of the test flight.
VideoFAA approves Starship test after saying SpaceX violated safety rules on last flight
SpaceX defied public safety rules on its most recent Starship launch over South Texas in December, the Federal Aviation Administration said Tuesday as it approved a license for SpaceX's next high-altitude Starship test flight scheduled for the same day.
Hydraulic system issue triggered early engine shutdown during SLS test-firing
NASA officials said Tuesday the weekend test-firing of the Space Launch System moon rocket's core stage was cut short by an out-of-limits parameter in a hydraulic system for gimbaling, or vectoring, one of its engines. NASA Administrator Jim Bridenstine told Spaceflight Now engineers are "feeling pretty good" about the data gathered during the shortened test-firing, and managers may decide to ship the SLS core stage to the Kennedy Space Center for launch preparations without re-attempting the planned eight-minute hot fire.
NASA studying cause of early end to moon rocket test-firing
A critical test-firing of NASA's Space Launch System moon rocket in Mississippi ended just 67 seconds after it began Saturday, well short of a planned eight-minute burn that was supposed to clear the way for the space agency to finally ship the rocket's core stage to the Kennedy Space Center in Florida for launch preparations.
Video: SLS core stage test-firing ends early
The four RS-25 engines at the bottom of NASA's first Space Launch System core stage shut down about a minute into a ground test-firing Saturday that was supposed to last more than eight minutes.
VideoLive coverage: SLS core stage engines shut down early during critical hotfire test
A critical test-firing of the Space Launch System's core stage engines cut off about a minute into a planned eight-minute burn Saturday on a test stand at NASA's Stennis Space Center in Mississippi. The rocket's four engines ignited at 5:27 p.m. EST (2227 GMT) for a test that was to pave the way for the core stage's shipment to the Kennedy Space Center for launch preparations.
