Orion integration on top of Moon launcher

Integration of the Orion spacecraft on top of the Space Launch System (SLS) rocket at NASA’s Kennedy Space Center in Florida.   The European Service Module that will power the first Orion uncrewed flight, ESM-1, was lifted up and mated with the rocket in preparation for launch, together with the crew module. Integration began on 20 October 2021, and the spacecraft was secured atop the powerful rocket six days later.  Artemis I is the first in a series of increasingly complex missions for human deep space exploration. The European Service Module will power Orion's crew module around the Moon and back with over 30 engines. The European Service Module provides electricity, water, oxygen and nitrogen as well as keeping the spacecraft at the right temperature and on course.
