Critical test of NASA space launch engine engine stops earlier than planned



NASA launches the main stage of its massive new rocket – Space launch system (SLS) – on Saturday (January 16th) in a critical test that seems to have ended prematurely when the booster’s engines stopped earlier than planned.

Smoke and flames erupted from the four RS-25 engines that powered the amplifier of the behemoth rocket’s core, a central element of NASA’s Artemis lunar program as it roared at the top of NASA’s test bench. Stenis Space Center near St. Louis Bay, Mississippi. The ignition occurred at 5:27 p.m. (2,227 GMT), with 700,000 gallons (2.6 million liters) of cryogenic fuel passing through the engines as they roared for just over 1 minute, much earlier than planned.
