It says it is preparing for the next launch opportunity as early as Friday, 23 September.
Officials stopped the original Saturday 3 September launch countdown after discovering a hydrogen leak in a quick disconnect, an interface between the hydrogen fuel feed line on the mobile launcher and the Space Launch System (SLS) rocket.
Nasa reports engineers are “making progress repairing the area”. Specifically, teams have replaced the seals on the Space Launch System rocket’s core stage associated with the leak. A line used to fill and drain liquid hydrogen from the core stage and a bleed line used to redirect some of the propellant during tanking operations were removed and replaced this week.
