Teams have started chilling down the lines used to feed liquid oxygen into the upper stage. Troubleshooting of liquid hydrogen loading into the core stage continues.
Teams have stopped the flow of liquid hydrogen through the tail service mast umbilical interface into the core stage after leak concentrations exceeded allowable limits. Stopping the flow allows engineers to perform troubleshooting procedures that were developed after Artemis I.…
As teams continue to fuel the SLS (Space Launch System) rocket’s core stage with liquid oxygen and liquid hydrogen, teams began propellant loading operations for the rocket’s interim cryogenic propulsion stage (ICPS), or upper stage. The launch control team is filling the ICPS with liquid hydrogen.…
Teams began chilling down the liquid hydrogen lines for the interim cryogenic propulsion stage of NASA’s SLS (Space Launch System) rocket. This critical step cools the propellant lines ahead of loading super-cold liquid hydrogen, chilled to minus 423 degrees Fahrenheit, into the SLS’s upper stage…
NASA teams have transitioned to fast fill of the SLS (Space Launch System) rocket’s core stage with super-cold liquid hydrogen, chilled to minus 423 degrees Fahrenheit and liquid oxygen chilled to minus 297 degrees. Fast fill rapidly loads hundreds of thousands of…
Following successful chilldown of the liquid hydrogen and liquid oxygen lines, teams started slowly filling the SLS (Space Launch System) rocket’s core stage with super-cold liquid hydrogen, chilled to minus 423 degrees Fahrenheit, then with liquid oxygen chilled to minus 297 degrees. This marks the official start of propellant loading for the…
NASA’s Orion spacecraft, which will carry the Artemis II crew around the Moon, sits at the launch pad on Jan. 17, 2026, after rollout. It rests atop the SLS (Space Launch System) rocket. Orion can provide living space on missions…
Teams have started chilling down the liquid hydrogen (LH2) and liquid oxygen (LOX) lines for the SLS (Space Launch System) rocket’s core stage. This critical step cools the propellant lines ahead of loading super-cold liquid hydrogen and liquid oxygen into the core stage tanks, which will eventually…
Following a fueling test of NASA’s SLS (Space Launch System) rocket at the launch pad for the Artemis II Moon mission, leaders will discuss initial results during a news conference at 12 p.m. EST on Tuesday, Feb. 3. The agency’s…
At approximately 11:25 a.m. EST, the Artemis launch director, in coordination with the mission management team chair, gave the “go” to begin loading cryogenic liquid propellant into the SLS (Space Launch System) rocket for wet dress rehearsal. While teams continue to monitor cold weather that would impact launch day, they are not…
