NASA test of mega Moon rocket engines cut short

NASA conducted a test firing of the engines for its giant Space Launch System (SLS) lunar rocket on Jan. 16 but they shut down earlier than planned, the space agency said.

The "hot-fire" test at the Stennis Space Center in Mississippi was supposed to last a little over eight minutes - the time the engines would burn in flight - but they shut down just over a minute into the burn.
