NASA Has a New Problem to Fix Before the Next Artemis II Countdown 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.

Again and Again

Fuel leaks are nothing new for the Space Launch System. The same kind of leak delayed the first test flight of the SLS rocket for several months in 2022. With that launch, ground teams thought they fixed the problem by changing how they load super-cold liquid hydrogen into the rocket’s core stage. The launch team used the same loading procedure February 2, but the leak cropped up again.
