Mobile Launcher Team Demonstration

James Fesmire, Ph.D., left, NASA lead engineer for the Cryogenics Testbed, holds a training session on Nov. 6, 2018, at the Cryogenics Laboratory at NASA's Kennedy Space Center in Florida. The training is for personnel who will be working to insulate pipes on the mobile launcher (ML). The ML is equipped with cryogenic fluid lines that will deliver hydrogen and oxygen to NASA's Space Launch System rocket. The lines must be kept well-insulated to maintain temperatures cold enough to keep fluids in a liquid state. In a new process, workers are learning how to pack spaces between pipes with aerogel granules in the same manner as they will on the ML.
