A NASA drone photo offers a bird’s-eye view of the B-2 Test Stand at NASA’s Stennis Space Center with the first flight core stage for NASA’s new Space Launch System (SLS) installed for Green Run testing. The SLS core stage is undergoing a series of tests on its integrated systems 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. The Green Run series at Stennis culminates with a hot fire of the core stage’s four RS-25 engines, just as during an actual launch.

The CSITU will be located at about the 140-foot level of the ML tower. The umbilical will be lowered down and installed permanently on the ML at a later date. The CSITU is a swing-arm umbilical that will connect to the Space Launch System core stage inter-tank. It will provide conditioned air, pressurized gases and power and data connection to the core stage. The Ground Systems Development and Operations Program is overseeing installation of the umbilicals.

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, liquid oxygen can be seen venting near the top of the installed core stage. Following the wet dress rehearsal, operators will conduct a full hot fire test of the core stage and its four RS-25 engines. 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.

Technicians at NASA’s Michoud Assembly Facility in New Orleans have installed the first of four RS-25 engines on the core stage of the agency’s SLS (Space Launch System) rocket that will help power NASA’s first crewed Artemis mission to the Moon. The Sept. 11 engine installation follows the joining of all five major structures that make up the SLS core stage earlier this spring. NASA, lead RS-25 engines contractor Aerojet Rocketdyne, an L3 Harris Technologies company, and Boeing, the core stage lead contractor, will continue integrating the remaining three engines into the stage and installing the propulsion and electrical systems within the structure. All four RS-25 engines are located at the base of the core stage within the engine section. NASA is working to land the first woman and first person of color on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with Orion and the Gateway in orbit around the Moon. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission.
