A 154-foot-long solid rocket booster will be ignited for two minutes Tuesday at a remote test site in Utah, wrapping up a series of five ground firings to prove the motor’s readiness for flight on NASA’s Space Launch System.

The launch faced long odds with poor weather in the forecast for a fourth day in a row, but SpaceX was able to launch from pad 40 at Cape Canaveral Space Force Station on Thursday, Sept. 11, at 9:56 p.m. EDT (0156 UTC).
