According to Junfeng ZOU, senior engineer at the Aerospace Institute of Advanced Materials and Processing Technology in Beijing, China has developed her own carbon aerogel products which insulate within a temperature range between – 100 and + 2,500 C. They are also capable to withstand vibrations. They are used on the heavy-duty Long March 5 rockets, on cargo spacecrafts, in space suits and on the future Mars rover.
