A critical test-firing of the Space Launch System’s core stage engines cut off about a minute into a planned eight-minute burn Saturday on a test stand at NASA’s Stennis Space Center in Mississippi. The rocket’s four engines ignited at 5:27 p.m. EST (2227 GMT) for a test that was to pave the way for the core stage’s shipment to the Kennedy Space Center for launch preparations.

NASA civil servants and the agency’s contractor work force are bracing for high winds and rain from Hurricane Dorian, securing rocket stages, spacecraft assembly areas and even hauling a 6.7-million-pound mobile launch tower, designed for the huge rocket being built for the Artemis moon program, back to the cavernous Vehicle Assembly Building for safekeeping.

NASA announced Monday that former U.S. Navy fighter pilots Reid Wiseman and Victor Glover, veteran space station astronaut Christina Koch, and rookie Canadian astronaut Jeremy Hansen will crew the Artemis 2 mission to fly around the far side of the moon as soon as late next year, a test flight that could carry the foursome farther from Earth than any humans in history.
