The launch of the Artemis 2 mission, intended to send four astronauts around the moon, is now delayed until at least April due to a helium flow issue with the Space Launch System rocket. NASA Administrator Jared Isaacman confirmed that the rocket must be rolled back from its launch pad for troubleshooting, expressing disappointment in a recent post on X.
This technical challenge emerged shortly after a successful launch-pad rehearsal at NASA's Kennedy Space Center. The interruption in helium flow, critical for pressurizing propellant tanks and engine purging, was detected during a routine operation aimed at repressurizing the system. Isaacman noted that the helium pressurization system had functioned properly during the wet dress rehearsal earlier this week.
The next potential launch dates for Artemis 2 are set for April 1 and the period from April 3 to April 6. The mission aims to achieve a historic figure-8 trajectory around the moon, marking the first human journey beyond Earth’s orbit since the Apollo 17 mission in 1972. Success in Artemis 2 will pave the way for the subsequent Artemis 3 crewed lunar landing.
