Orion helium leak no threat to Artemis II reentry, but will require redesign

What Happened

Apart from pesky issues with the spacecraft's toilet and waste disposal system, most of the Artemis II mission has proceeded like clockwork.

Why It Matters

NASA has made few changes to the flight plan since the launch of the lunar flyby mission April 1.

  • The four astronauts were supposed to take manual control of their Orion spacecraft, named Integrity, for a piloting demonstration Wednesday night.
  • Instead, mission managers canceled the demo to make time for an additional test of the ship's propulsion system.
  • The goal was to gather data on a "small leak" of helium gas, which Orion uses to push propellant through a series of tanks and pipes to feed the spacecraft's rocket engines, said Jeff Radigan, NASA's lead flight director for the Artemis II mission.Read full article Comments
