NASA Stennis teams complete a water system activation milestone on Jan. 30 at the Thad Cochran Test Stand (B-2). The milestone tested new cooling systems added to the stand for the future Green Run test series of NASA\u2019s exploration upper stage that is expected to fly on the Artemis IV mission.<\/div>\n

A water system activation at the Thad Cochran Test Stand (B-2) on Jan. 30 at NASA\u2019s Stennis Space Center near Bay St. Louis, Mississippi, helped capture critical data to support testing a new SLS (Space Launch System) stage expected to fly on the Artemis IV mission.<\/p>\n

The activation milestone tested new cooling systems that were added for the future Green Run test series of NASA\u2019s exploration upper stage (EUS). The more powerful upper stage is a four-engine liquid hydrogen\/liquid oxygen in-space stage for the evolved Block 1B version of SLS.<\/p>\n
