These photos, taken in fall 2024, show how NASA engineers use the Hub for Innovative Thermal Technology Maturation and Prototyping (Hi-TTeMP) laboratory at NASA’s Marshall Space Flight Center in Huntsville, Alabama. NASA engineers working in the HI-TTeMP lab not only design, set up, and run tests, they also provide insight and expertise in thermal engineering to assist NASA’s industry partners, such as SpaceX and other organizations, in validating concepts and models, or suggesting changes to designs. The lab is able to rapidly test and evaluate design updates or iterations. Engineering teams inside the lab are currently testing how well prototype insulation for SpaceX’s Starship HLS (Human Landing System) will insulate interior environments, including propellant storage tanks and the crew cabin. Starship HLS will land astronauts on the lunar surface during Artemis III and Artemis IV.
