NASA's Artemis 2 mission has been hit with another setback after a hydrogen leak was detected during the wet dress rehearsal in early February. The agency had initially hoped to launch the mission as soon as February 6, but now it will have to wait until March.
The wet dress rehearsal is an essential test of the spacecraft before its actual launch, and it's designed to surface any issues that may arise during flight. However, this one revealed a liquid hydrogen leak in the Space Launch System rocket, which took NASA engineers several hours to troubleshoot.
Fortunately, they were able to fix the issue and continue with the countdown, but just as things were going smoothly, another problem popped up at approximately five minutes before launch. The ground launch sequencer automatically stopped due to an unexpected spike in the spacecraft's liquid hydrogen leak rate.
While the agency acknowledges that there are still other issues to address, including how cold weather may affect equipment during the actual launch, it will now focus on resolving these problems before announcing a new launch window for Artemis 2. To do this, NASA plans to review data from the recent rehearsal and conduct another test to confirm that all is well.
The delay in the mission's schedule comes as no surprise given that it has been over three years since NASA last launched its Space Launch System rocket. The agency expects challenges during complex missions like Artemis 2, which is one of the most ambitious space exploration projects currently underway.
For now, NASA administrators have made a temporary adjustment to their plans, pushing back the earliest launch opportunity for Artemis 2 to March. As always, safety and success will be top priorities for this critical mission.
