A critical NASA rocket test ended with a shutdown on Saturday, a little over a minute into what was planned to be an eight-minute test. This trial run was a vital checkpoint for NASA’s much-delayed Space Launch System. The SLS is set to play a key role in the agency’s Artemis program which aims to return astronauts to the Moon.
During today’s Green Run test, the four rocket engines in the SLS core fired for a little over a minute while anchored in NASA’s rocket test stand. The team had planned to have the engines fire for approximately eight minutes, or about the same amount of time it will take to launch future missions to the Moon.
