Fisher and the thermal protection system team develop and apply the spray-on foam that acts as insulation and protects the adapter and all its systems from the extreme pressures and temperatures it’ll face during flight. The thermal protection system for the component, unlike other parts of the rocket, is applied by hand using a spray gun. When first applied, the insulation is yellow, but after time and exposure to the Sun, it turns orange.

“We’re taking the same stuff someone might use to insulate their attic, except making it for cryogenic atmospheres, and spraying it all over a giant piece of hardware that will help launch us to the Moon,” Fisher said. “With my work for NASA’s Space Launch System rocket, I get to play with foam and glue. I like to call it arts and crafts engineering!”
