The Pearl River County Leadership Class visits the Thad Cochran Test Stand (B-1/B-2) during a NASA Stennis tour on Feb. 20. NASA Stennis is at the front end of the critical path for the future of human deep space exploration through NASA’s Artemis campaign. The B-2 side of the Thad Cochran Test Stand is undergoing preparations for exploration upper stage testing. The upper stage is scheduled to undergo Green Run tests of its integrated systems before its first flight on the Artemis IV mission. The test series will culminate with a hot fire of the stage’s four RL10 engines, just as during an actual mission.
