GPIM was the second flight for IMLI, and continued to expand spaceflight heritage for Quest Thermal Group’s insulation technology. IMLI was deployed in a passive thermal management role and performed as expected and modeled, continuing to prove IMLI for spaceflight use. NASA’s STP-2 mission, which launched GPIM, was a rideshare for GPIM and other technology demonstrations on the first Falcon 9 Heavy launch.
