NASA engineers finish second countdown test<\/h2>\n

Inside NASA\u2019s Vehicle Assembly Building, engineers conducted the second countdown test of the SLS rocket. This test checked to make sure ground software and what is known as the sequencer performed as intended.<\/p>\n

A launch sequencer is a software program that controls the launch countdown. While humans are in the loop, the sequencer is checking to make sure everything is starting on time and performing smoothly. If something is not acting as intended, it can hold the countdown or even abort it automatically.<\/p>\n

The sequencer would take over complete control at T-30 seconds during an actual countdown. This test concluded before that point.<\/p>\n
