NASA Artemis II hydrogen leak space exploration
NASA's Artemis II mission is facing ongoing challenges with liquid hydrogen leaks that are becoming increasingly problematic. The Space Launch System rocket, intended to carry astronauts around the Moon, has experienced repeated instances of hydrogen seepage during testing, raising questions about the vehicle's readiness.

The persistent leaks echo similar issues that plagued the Artemis I uncrewed mission, which also faced multiple launch delays due to hydrogen leaks before successfully flying in 2022. Engineers are working to identify and resolve the root cause, but the recurring nature of the problem is starting to cause concern about potential delays to the crewed mission schedule. Artemis II is a critical step in NASA's plan to return humans to lunar orbit for the first time since the Apollo era.
