Teams have begun the slow fill phase to load liquid hydrogen (LH2) and liquid oxygen (LOX) into the Space Launch System rocket’s core stage. Once LH2 and LOX slow fill is complete, teams will transition to fast fill operations.
Below are the as scheduled times for slow and fast fill operations:
- 4:24 p.m.: Core stage LH2 slow fill start (L-8H45M – L-7H50M)
- 4:44 p.m.: Core stage LOX slow fill (L-8H20M – L-8H5M)
- 5:04 p.m.: Core stage LOX fast fill (L-8H5M – L-5H15M)
- 5:14 p.m.: Core stage LH2 fast fill (L-7H50M – L-6H10M)
