The Interim Cryogenic Propulsion Stage (ICPS) stands suspended in a silo-like structure at NASA’s Kennedy Space Center in Florida. This graphic shows what the ICPS looks like from inside the tower. The ICPS, which will lie just below the Orion capsule, at the top of NASA’s Space Launch System rocket, is a liquid oxygen/liquid hydrogen-based system that will give Orion the big in-space push needed to fly beyond the Moon.
