Balancing insulation and lightweighting in extreme space environments is the core challenge for aerospace materials. The aerogel silica composite developed by XX Research Institute gives an innovative answer: nano silica is evenly dispersed in the silica aerogel framework to form "core-shell structure" particles. The material maintains structural stability within the range of -180 ℃ to 1200 ℃, with a thermal conductivity as low as 0.012W/m · K and a density only 1/5 of aluminum. In 2025, this material has been applied to the thermal control system of the Chang'e-7 lunar probe, successfully withstanding the high temperature of 127 ℃ during the day and the extreme cold of -183 ℃ at night. In the future, it may become the "insulation jacket" for deep space exploration equipment such as Mars rovers and space stations.
