Stacking is ready for the Space Launch System (SLS) twin rocket upgrade for NASA’s Artemis I mission. Over several weeks, workers used one of five large cranes to lift ten sections and place nose assemblies on the mobile launcher inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida. Engineers with Exploration Ground Systems delivered the first section on November 21, 2020, and continued the process until the final nose assembly was installed on March 2, 2021. When the SLS Kennedy base level is reached, technologists transported it to the VAB and then stacked it on the mobile device between the two elevations. Artemis I will be a fragmented test of the Orion spacecraft and SLS rocket as a unified system ahead of crew flights to the Moon. Under the Artemis program, NASA aims to land the first and next female on the Moon and establish a permanent lunar study. NASA photo by Isaac Watson / UPI
