The four RS-25 engines at the bottom of NASA’s first Space Launch System core stage shut down about a minute into a ground test-firing Saturday that was supposed to last more than eight minutes.

The United Launch Alliance Delta 4-Heavy rocket lifts off with NASA’s Orion spacecraft on its inaugural space flight test at 7:05 a.m. EST Dec. 5 from Cape Canaveral Air Force Station’s Complex 37.

With the Space Launch System’s inaugural test flight now officially delayed to November 2021, NASA says work halted by the coronavirus pandemic will resume within weeks to prepare for the first test-firing of the SLS core stage at the Stennis Space Center in Mississippi.
