A little while ago, NASA’s Orion spacecraft separated from the last stage, called the ICPS (Interim Cryogenic Propulsion Stage), of the Space Launch System (SLS), which blasted off almost two hours earlier from the Kennedy Space Center. The Orion entered the trajectory that will take it into the Moon’s orbit to carry out its mission which will last about 25 days. This is the first launch for the SLS and for the Orion in its full configuration. The ICPS also has the secondary mission of putting some CubeSat-class nanosatellites into orbit.
