NASA engineers could not overcome a hydrogen leak between a fuel feed line and their new Space Launch System (SLS) rocket on Saturday and decided to scrub the launch attempt and review their options for the coming weeks.
Over the next several days, teams will gain access to the area of the leak on Launch Pad 39B at Kennedy Space Center, Fla., and in parallel conduct a schedule assessment and make a decision on whether to perform repairs on the rocket at the launch pad or roll it back inside the Vehicle Assembly Building.
During Saturday's launch attempt, engineers saw a leak in a cavity between the ground side and rocket side plates surrounding an eight-inch line used to fill and drain liquid hydrogen from the SLS rocket. Three attempts at reseating the seal were unsuccessful, NASA officials said Saturday.
The space mission, known as Artemis I, is a flight test to launch NASA’s new SLS rocket and an uncrewed Orion spacecraft around the moon before the Artemis II mission is launched carry astronauts.
A new launch date has not been announced yet.
