Overview
- NASA canceled the March launch window, dropping the March 6 target after the issue surfaced.
- During a standard repressurization, teams could not get helium to flow through the upper-stage ICPS despite earlier wet dress tests operating normally.
- The SLS is slated to roll 6.4 kilometers back to the Vehicle Assembly Building as early as Tuesday, weather permitting, for inspections and repairs.
- Investigators are examining possibilities that include an umbilical-line filter blockage, a faulty quick-disconnect interface, or an internal valve problem.
- April is being discussed as a possible window, but any new date depends on repairs and repeat verification testing.
