Halted rocket test could stall NASA moon shot, redo possible

NASA is considering a second firing of its moon rocket engines after a critical test came up short over weekend, a move that could bump first flight in Artemis lunar-landing program into next year.

ncy had aimed to launch its new Launch System, or SLS, rocket and an empty Orion capsule by end of this year, with capsule flying to moon and back as a prelude to crew missions. But that date could be in jeopardy following Saturday’s aborted test.

All four engines fired for barely a minute, rar than intended eight minutes, on test stand at NASA's Stennis Center in Mississippi. countdown rehearsal for 212-foot (65-meter) core st — made by Boeing — included liquid hydrogen and oxygen tanks, as well as all necessary computers and electronics.

On Tuesday, NASA attributed automatic shutdown to strict test limits meant to protect core st so it can be used on first Artemis flight. hydraulic system for one engine exceeded safety parameters, officials said, and flight computers shut everything down 67 seconds into ignition.

Two or engine-related issues also occurred.

NASA said it can adjust test limits if a second test is deemed necessary, to prevent ar premature shutdown. Engineers will continue to analyze data before deciding on next step.

Artemis program is working to put astronauts back on moon by 2024, a deadline set by Trump administration. It's uncertain how incoming White House will approach that timeline.
