NASA has a new problem to fix before the next Artemis II countdown test

Here's something that might surprise you — NASA’s got a new headache before their next big moon shot. Jared Isaacman, NASA’s boss, said they’re working hard to fix the fueling issues that’s been holding back the Space Launch System. Now, why does this matter? Well, Artemis III, the first moon landing since the Apollo days, depends on a smooth launch. According to Stephen Clark from Ars Technica, they’re doing another countdown rehearsal next week to nail down a hydrogen leak problem that cut short a recent test. This is crucial because Artemis II, the first crewed flight of the SLS, is scheduled to circle the Moon and bring astronauts home — an almost 10-day journey. But here’s where it gets interesting — NASA’s really under pressure to get this right. As Clark reports, the agency’s vowed to iron out these fueling issues before Artemis III, which is their big moon landing goal. So, stay tuned — there’s a lot riding on this next test.

NASA Administrator Jared Isaacman said Saturday the agency is looking at ways to prevent the fueling problems plaguing the Space Launch System rocket before the Artemis III mission.

Artemis III is slated to be the first crew mission to land on the Moon since the Apollo program more than 50 years ago. As for Artemis II, which remains on the launch pad at Kennedy Space Center in Florida after missing a launch window earlier this month, NASA is preparing for a second countdown rehearsal as soon as next week to confirm whether technicians have resolved a hydrogen fuel leak that cut short a practice countdown run February 2.

Artemis II is the first crew flight for SLS rocket and Orion spacecraft. The nearly 10-day mission will carry four astronauts around the far side of the Moon and return them to Earth.
