NASA’s crewed Artemis II launch gets pushed back again, this time due to a helium issue

It appears like a March launch is now not within the playing cards for Artemis II, NASA’s first crewed journey to the moon’s neighborhood for the reason that closing Apollo mission over 50 years in the past. Whereas preparations have been underway on the Kennedy Area Middle for a launch as soon as March 6, the space agency says it bumped into a problem with the stream 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 mistaken and repair it. A media briefing is deliberate for someday this week to debate the issue and what’s subsequent.

However in a put up 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 “probably preserves the April launch window, pending the end result of information findings, restore efforts, and the way the schedule involves fruition within the coming days and weeks.” It is a four-mile journey again to the VAB that can take hours to rigorously transport the large rocket and the Orion spacecraft. NASA says it is eyeing February 24 for this trek.

The problem occurred in a single day within the early hours of February 21, when NASA says it noticed “interrupted stream of helium to the SLS (Area Launch System) rocket’s interim cryogenic propulsion stage.” The area company explained:

The higher stage makes use of helium to take care of the correct environmental circumstances for the stage’s engine and to pressurize liquid hydrogen and liquid oxygen propellant tanks. The methods labored throughout NASA’s Artemis II moist gown rehearsals, however groups weren’t capable of correctly stream helium throughout regular operations and reconfigurations following the moist gown rehearsal that concluded Feb. 19. Operators are utilizing a backup methodology to take care of the environmental circumstances for the higher stage engines and the rocket, which stays in a protected configuration.

The Artemis II crew — Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch and Canadian Area 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.

Initially 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 targeted early February, the launch was pushed to March resulting from points that popped up through the moist gown rehearsal. Now, we’re again to the start with a doable April launch, however that’ll rely on the repair being a fast one.
