Teams are in fast fill operations for the interim cryogenic propulsion stage’s (ICPS) liquid hydrogen and liquid oxygen tanks. The ICPS is the upper stage of the Space Launch System rocket responsible for giving the Orion spacecraft the big push it needs in space to head toward the Moon.
Teams continue to work toward a two-hour launch window that opens at 1:04 a.m. EST, from Launch Pad 39B at NASA’s Kennedy Space Center in Florida.
Coverage of tanking operations continues on NASA TV and the agency’s website and the NASA app. A full launch broadcast will begin at 10:30 p.m. EST in English and at midnight, Spanish coverage begins on the NASA en español YouTube page.
