Exploration Ground Systems
NASA's Exploration Ground Systems (EGS) Program is one of three programs based at NASA's Kennedy Space Center in Florida. EGS was established to develop and operate the systems and facilities necessary to process and launch rockets and spacecraft during assembly, transport and launch. EGS is preparing the infrastructure to support NASA's Space Launch System (SLS) rocket and its payloads, such as the Orion spacecraft for Artemis I. Artemis I is the first to launch in a series of increasingly complex missions that will enable human exploration to the Moon and Mars.

ML-1
The Space Launch System (SLS) is an American super heavy-lift expendable launch vehicle used by NASA. As the primary launch vehicle of the Artemis Moon landing program, SLS is designed to launch the crewed Orion spacecraft on a trans-lunar trajectory. The first SLS launch was the uncrewed Artemis 1, which took place on 16 November 2022.
