NASA’s Artemis 2 mission has reached a major milestone as the second stage that powers the Artemis 2 rocket, the Interim Cryogenic Propulsion Stage (ICPS), has been stacked. Kennedy Space Centre in Florida’s technicians mounted the ICPS on top of the SLS rocket inside the Vehicle Assembly Building on May 1. Driven by its upper stage, NASA’s Orion spacecraft and four-person crew—three NASA astronauts and one Canadian—out of Earth orbit will travel a free-return path around the moon, therefore allowing NASA’s return to deep space exploration. NASA Advances Artemis 2 Moon Mission as Future of SLS and Orion Faces Uncertainty As per NASA’s announcement, the ICPS arrived at the VAB last month and was hoisted into position inside the rocket stage adapter. The stage is critical for completing the crew’s journey past low Earth orbit during the 10-day Artemis 2 mission. Images shared by NASA show the second stage being lowered into place, while the Orion spacecraft and service module, delivered this week by Lockheed Martin, await integration. Exploration Ground Systems will process the Orion module …
