NASA’s Orion spacecraft will fly a two-orbit, four-hour mission for Exploration Flight Test No. 1 in Earth orbit to test systems.

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.

The budget proposal coming from the White House would also reduce spending on the International Space Station program by more than $500 million.
