Aerogels are used for thermal insulation on the Russian Space Station Mir and the US Mars Pathfinder because of their low thermal conductivity, excellent thermal insulation, light mass and strong compression resistance. Aerogels are also used to insulate the interlayer of spacesuits to protect astronauts. In November 2016, China's more capable rocket Long March 5 first flew successfully, in April 2017, the Tianzhou-1 cargo ship launched, successfully achieved the rendezvous and docking with Tiangong-2. in both launch missions, aerogels are indispensable high-end thermal insulation products.

Application extension: Aerogel insulation material can be used as thermal insulation material for aircraft engine room. The utility model can be used as a high efficiency heat insulation material for nuclear submarines, steam power missile destroyers, nuclear reactors, evaporators, boilers and complex high temperature steam pipeline systems, which can enhance the heat insulation effect and reduce the temperature in the cabin, at the same time effectively reduce the amount of heat insulation material, increase the space for use in the cabin, and effectively improve various working environments.

Aerogel thermal insulation materials can use lighter mass, smaller volume to achieve better thermal insulation effect, this feature is the most mature and reliable application in aerospace applications.
