3 days agoRocket Report: SpaceX probes upper stage malfunction; Starship testing resumes
The big news in rocketry this week was that NASA still hasn't solved the problem with hydrogen leaks on the Space Launch System. The problem caused months of delays before the first SLS launch in 2022, and the fuel leaks cropped up again Monday during a fueling test on NASA's second SLS rocket. It is a continuing problem, and NASA's sparse SLS launch rate makes every countdown an experiment, as my colleague Eric Berger wrote this week.
