It's Helium's Fault - NASA Artemis 2
from The SpaceInfo Podcast · host SpaceInfo Club
According to NASA, telemetry data revealed an interruption in helium flow to the rocket’s Interim Cryogenic Propulsion Stage (ICPS), the upper stage responsible for sending Orion out of Earth orbit and toward the Moon. Helium is essential for pressurizing propellant tanks and supporting proper engine conditioning prior to ignition. Without stable helium flow, the stage cannot be certified for flight.
