This piece of cloth can not only prevent heat, but also keep it warm

The shiny outermost layer is really gold, which can reflect most of the sun's rays and prevent the spacecraft from overheating when exposed to the sun. . However, the spacecraft will not only encounter exposure to the sun, but also move into the shadow of the celestial body and suddenly cool down. The multiple layers of materials inside the picture above can prevent external heat from suddenly entering, and can also prevent internal heat from quickly dissipating.

Overall, this piece of gold cloth narrows the temperature change range of the spacecraft and also reduces the temperature change rate.

The use of gold also has other purposes, which is to protect against ionizing radiation and various ions and particles.

Generally, lead is sufficient for ground protection against ionizing radiation, but gold has a higher density (different materials have different blocking coefficients for ionizing radiation. I don’t remember the professional term for the coefficient. Lead is high. Gold is higher) It has a very good blocking effect on various radiations in space, mainly various particles and ions. If a computer in space is hit by a charged particle, the circuit may have a bit reversal, which is the circuit. A certain bit of the data is interchanged between 0 and 1, which will cause unpredictable problems

So not only the satellites have packages, but the astronauts' masks are also gold-plated, which is more for radiation protection. Function
