Barges are docked at the B-2 Test Stand at Stennis Space Center on Dec. 4, 2020, in preparation for upcoming Green Run test activities. Teams at the center have been performing Green Run tests of NASA’s Space Launch System core stage and its integrated systems throughout 2020. In mid-December, teams performed the seventh test of the Green Run series – a wet dress rehearsal of a countdown to hot fire. It marked the first time the stage tanks had been loaded with liquid oxygen and liquid hydrogen propellants supplied by the docked barges.

On Jan. 21-22, 2020, crews at Stennis Space Center lifted and installed the first core stage of NASA’s new Space Launch System (SLS) rocket onto the B-2 Test Stand. In upcoming months, a top-to-bottom, integrated series of Green Run tests will be conducted on the stage and its sophisticated systems. Following testing, the stage will be used to help launch the maiden Artemis I test mission of SLS and the Orion spacecraft. Through the Artemis program, NASA will send humans, including the first woman and next man, to the Moon to establish a sustainable presence.

The first flight core stage for NASA’s new Space Launch System rocket arrived at Stennis Space Center on Jan. 12 for a series of tests prior to its maiden Artemis I flight. The core stage was transported from Michoud Assembly Facility in New Orleans to the B-2 Test Stand dock at Stennis aboard NASA’s Pegasus barge. Soon after arrival, the stage was rolled off of Pegasus onto the B-2 Test Stand tarmac. After the stage is lifted and installed on the B-2 stand, it will undergo a series of “Green Run” systems test that represent the first integrated testing of its sophisticated systems.

The core stage was transported from Michoud Assembly Facility in New Orleans to the B-2 Test Stand dock at Stennis aboard NASA’s Pegasus barge. Soon after arrival, the stage was rolled off of Pegasus onto the B-2 Test Stand tarmac. After the stage is lifted and installed on the B-2 stand, it will undergo a series of “Green Run” systems test that represent the first integrated testing of its sophisticated systems.

A photo from the north (flame trench) side of the B-2 Test Stand at NASA’s Stennis Space Center shows the first flight core stage for NASA’s new Space Launch System (SLS) rocket installed for Green Run testing. The SLS core stage was transported to Stennis in January to begin Green Run testing prior to its use on the Artemis I mission. NASA is building SLS to return humans, including the first woman, to the Moon as part of the Artemis program and to prepare for eventual missions to Mars. At Stennis, the SLS core stage will undergo a series of tests on its integrated systems, culminating with a hot fire of its four RS-25 engines, just as during an actual launch.

Barges are docked at the B-2 Test Stand at Stennis Space Center near Bay St. Louis, Mississippi, during preparations for a wet dress rehearsal exercise with the core stage of NASA’s Space Launch System rocket. During the wet dress rehearsal, operators will fully load the core stage’s propellant tanks for the first time and countdown just shy of engine ignition. The wet dress rehearsal is the seventh in a series of eight Green Run tests of the core stage’s integrated systems prior to its transport to Kennedy Space Center and launch on the Artemis I mission.

Operators at the B-2 Test Stand at Stennis Space Center near Bay St. Louis, Mississippi, conducted a wet dress rehearsal for the hot fire test of the core stage of NASA’s Space Launch System on Dec. 21, 2020. In this image, water flows from the B-2 Test Stand flame deflector, just as it will during an actual hot fire test. The hot fire will conclude a series of eight Green Run tests of all core stage systems before it is transported to Kennedy Space Center for launch on the Artemis I mission.
