Teams with NASA’s Exploration Ground Systems and contractor Jacobs integrate the interim cryogenic propulsion stage (ICPS) for NASA’s Space Launch System (SLS) rocket with the launch vehicle stage adapter (LVSA) atop the massive SLS core stage in the agency’s Vehicle Assembly Building (VAB) at NASA’s 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 Moon.

It is the in-space stage that is located toward the top of the rocket, between the Launch Vehicle Stage Adapter and the Orion Spacecraft Adapter. It will provide some of the in-space propulsion during Orion's first flight test atop the SLS on Exploration Mission 1.

The Space Launch System (SLS) rocket’s interim cryogenic propulsion stage (ICPS) moved into the Multi-Payload Processing Facility February 18, 2021, at NASA’s Kennedy Space Center in Florida for the Artemis I mission. It will undergo fueling and servicing in the facility ahead of launch by teams from NASA’s Exploration Ground Systems and their primary contractor, Jacobs Technology. Artemis I will be an integrated flight test of the SLS rocket and Orion spacecraft ahead of the crewed flights to the Moon. Under the Artemis program, NASA will land the first woman and the next man on the lunar surface and establish a sustainable presence at the Moon to prepare for human missions to Mars.
