Two months after glitches cut short an initial attempt on January 16, the 21-story SLS core stage's four shuttle-heritage RS-25 main engines were expected to ignite one after the other, at 120 millisecond intervals, throttling up to a combined thrust of 1.6 million pounds. The two-hour test window opens at 3 p.m. EDT.
