NASA Holds Artemis II Flight Readiness Review as Teams Fix Helium-Flow Fault

Teams report a helium-flow fault in ground equipment has been fixed ahead of rollout planning.

Overview

  • NASA is conducting the Artemis II Flight Readiness Review today, with a briefing scheduled later Thursday to update mission readiness and expected launch timing.
  • Engineers traced the helium-flow issue to a ground-support equipment filter and replaced it, clearing a key hurdle after the vehicle’s rollback to the Vehicle Assembly Building.
  • Final pad-readiness tasks, including flight battery work and seal checks, are in progress as planners eye early-April launch opportunities and a return to Launch Complex 39B later this month.
  • Artemis II is a roughly 10-day lunar flyby to validate deep-space systems with four astronauts: Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency’s Jeremy Hansen.
  • A separate NASA Inspector General report flags crew-safety and testing gaps in the human lander program for future lunar surface missions, with NASA agreeing to most recommended fixes.
