SpaceX has put Starship launches on hold while regulators investigate a mishap during last week’s test flight, according to multiple reports. The Federal Aviation Administration (FAA) said Wednesday that the flight—lasting about an hour—experienced a mishap linked to the performance of Starship’s first-stage booster during descent. Reports describe that minutes after liftoff from Texas, the booster separated as planned, but engines shut down or failed as it returned to Earth. Instead of a controlled splashdown in the Gulf of Mexico, the booster landed hard. The FAA reports there are no injuries or property damage. SpaceX continues the broader mission objectives by having the spacecraft travel around the world and release 20 mock satellites. The flight then ends as planned with a fiery splashdown in the Indian Ocean. The FAA will oversee the company’s investigation into the cause of the mishap. The 407-foot (124-metre) Starship rocket is SpaceX’s latest and largest Starship configuration. It is also tied to longer-term goals for crewed missions, including potential NASA work toward landing astronauts on the Moon later this decade.
