NASA successfully tested the insulation of gas-powered spacecraft

Currently, most high-temperature insulation systems used to protect the outer spacecraft use hard materials. The US aviation agency has recently successfully researched a type of thermal insulation for gas-powered spacecraft, hoping to slightly reduce the weight of future spacecraft.

According to US media reports on the 19th, the new type of thermal insulation was named ' IREVE '. At the US air agency's flight base in Virginia state, experts used a small rocket to carry it into space for testing, the test results were successful.

According to US research center NASA-LRC, the test results have made people very satisfied, thermal insulation and rockets are safely separated, ensuring safe testing back to the earth's atmosphere .

Currently, the spacecraft's thermal insulation systems use hard materials, there are some types in the process of passing through the biodegradable atmospheric layer, sometimes when entering the self-extracting atmosphere, the probe American Mars after flying through the atmosphere, the insulation protection system also automatically separated.

But the disadvantage of this insulation system is that the weight is too heavy, leading to the limitation of the transport of spacecraft. In addition, the volume of the insulation system is also limited, because it must contain a rocket.

Gas thermal insulation has solved this problem. The material of IRVE is very light, made of special layers of materials with good heat resistance, with a weight of 40 kg, when the gas volume is not loaded very small. Therefore, these spacecraft using thermal insulation will be very effective in transport. After launching, IRVE can fill gas to a relatively large volume, protecting the ship when it passes through the atmosphere.

NASA-LRC Research Center said that gas-type thermal imaging can be used for Titan and Mars satellite probes, or it can be used to return to transport ships between the earth and the space station. sacrifice.
