It appears like a March launch is not within the playing cards for Artemis II, NASA's first crewed journey to the moon's neighborhood because the last Apollo mission over 50 years in the past. Whereas preparations have been underway on the Kennedy House Heart for a launch as quickly as March 6, the house company says it bumped into a difficulty with the circulation of helium to its SLS rocket's higher stage this weekend and it now has to roll the rocket from the launch pad again to the Car Meeting Constructing (VAB) to determine what's unsuitable and repair it. A media briefing is deliberate for someday this week to debate the issue and what's subsequent.
However in a publish on X, NASA Administrator Jared Isaacman confirmed the rollback will "take the March launch window out of consideration." NASA famous on its weblog that the present effort "doubtlessly preserves the April launch window, pending the result of knowledge findings, restore efforts, and the way the schedule involves fruition within the coming days and weeks." It's a four-mile journey again to the VAB that can take hours to fastidiously transport the large rocket and the Orion spacecraft. NASA says it's eyeing February 24 for this trek.
The difficulty occurred in a single day within the early hours of February 21, when NASA says it noticed "interrupted circulation of helium to the SLS (House Launch System) rocket’s interim cryogenic propulsion stage." The house company defined:
The higher stage makes use of helium to keep up the correct environmental circumstances for the stage’s engine and to pressurize liquid hydrogen and liquid oxygen propellant tanks. The techniques labored throughout NASA’s Artemis II moist gown rehearsals, however groups weren’t in a position to correctly circulation helium throughout regular operations and reconfigurations following the moist gown rehearsal that concluded Feb. 19. Operators are utilizing a backup methodology to keep up the environmental circumstances for the higher stage engines and the rocket, which stays in a secure configuration.
The Artemis II crew — Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch and Canadian House Company astronaut Jeremy Hansen, Mission Specialist — had simply entered quarantine a day earlier than the difficulty arose. NASA says the astronauts have since come out of quarantine.
At first of this yr, NASA introduced an accelerated timeline for Artemis II, which was beforehand set for April 2026 after experiencing delays in 2024. For this 10-day mission, which would be the first crewed flight of the SLS rocket, the Artemis II astronauts will make a journey across the moon within the Orion spacecraft. Whereas it initially focused early February, the launch was pushed to March on account of points that popped up throughout the moist gown rehearsal. Now, we're again to the start with a attainable April launch, however that’ll depend upon the repair being a fast one.
