Teams with NASAs Exploration Ground Systems and contractor Jacobs integrate the interim cryogenic propulsion stage (ICPS) for NASAs Space Launch System (SLS) rocket with the launch vehicle stage adapter (LVSA) atop the massive SLS core stage in the agencys Vehicle Assembly Building (VAB) at NASAs Kennedy Space Center in Florida on July 5, 2021. The ICPS is a liquid oxygen and liquid hydrogen-based system that will fire its RL 10 engine to give the Orion spacecraft the big in-space push needed to fly tens of thousands of miles beyond the Moon. The next component to be stacked on top of ICPS will be the Orion stage adapter, which will connect the ICPS with the spacecraft. Through Artemis, NASA will send the first woman and the first person of color to the lunar surface, as well as establish a sustainable presence on and around the Moon. As the first in an increasingly complex set of missions, Artemis I will test SLS and Orion as an integrated system prior to crewed flights to the Moo
