New problems for Artemis II mission: Rocket returns to hangar, NASA postpones launch
Engineers faced problems on Friday night when trying to re-pressurize helium tanks on the upper stage of the Artemis II rocket. Due to this failure, the huge rocket will have to be withdrawn from the launch pad and returned to the hangar for detection and troubleshooting. This procedure will postpone the already delayed mission from March to early April, NASA officials announced on Saturday.
TL;DR
- Artemis II rocket faces a new problem with helium tank pressure, requiring it to be moved back to the Vehicle Assembly Building.
- The issue will delay the launch, originally planned for March, to early April.
- The mission will send four astronauts on a flight around the far side of the Moon.
- Previous delays were caused by a hydrogen leak during an earlier test.
- Astronauts have been released from pre-flight quarantine as they await the new launch date.
