Unable to tame hydrogen leaks, NASA delays launch of Artemis II until March
The launch of NASA's Artemis II mission, the first flight of astronauts to the Moon in more than 53 years, will have to wait another month after a fueling test Monday uncovered hydrogen leaks in the connection between the rocket and its launch platform at Kennedy Space Center in Florida.
"Engineers pushed through several challenges during the two-day test and met many of the planned objectives," NASA said in a statement following the conclusion of the mock countdown, or Wet Dress Rehearsal (WDR), early Tuesday morning. "To allow teams to review data and conduct a second Wet Dress Rehearsal, NASA now will target March as the earliest possible launch opportunity for the flight test."
The practice countdown was designed to identify problems and provide NASA an opportunity to fix them before launch. Most importantly, the test revealed NASA still has not fully resolved recurring hydrogen leaks that delayed the launch of the unpiloted Artemis I test flight by several months in 2022. Artemis I finally launched successfully after engineers revised their hydrogen loading procedures to overcome the leak.
