NASA says it needs to haul the Artemis II rocket back to the hangar for repairs

Here's something that caught my attention — NASA’s Artemis II mission, which was nearly ready to send astronauts around the Moon, just hit a snag. The agency’s head, Jared Isaacman, announced that a helium flow issue in the rocket’s upper stage means they need to roll the massive 322-foot-tall SLS back to the Vehicle Assembly Building. According to Stephen Clark at Ars Technica, this problem showed up Friday evening, and now engineers are investigating the cause. But here’s where it gets interesting — fixing it isn’t happening on the launch pad. Instead, NASA will use its crawler-transporter to carry the rocket four miles back inside the building for repairs. Now, this could delay the launch, which was tentatively set for next month. So what does this mean for NASA’s plans? It’s a reminder that space exploration always has surprises — and sometimes, things don’t go quite as planned. And get this — NASA’s team is working fast, but the clock is ticking.
