The thermal control subsystem can be composed of both passive and active items and works in two ways: Protects the equipment from overheating, either by thermal insulation from external heat fluxes (such as the Sun or the planetary infrared and albedo flux), or by proper heat removal from internal sources (such as the heat emitted by the internal electronic equipment).
One classical thermal escape mechanism is Jeans escape, [1] named after British astronomer Sir James Jeans, who first described this process of atmospheric loss. [2] In a quantity of gas, the average velocity of any one molecule is measured by the gas's temperature, but the velocities of individual molecules change as they collide with one another, gaining and losing kinetic energy.
The spacecraft now resides in the National Air and Space Museum in Washington, D.C.

This article is a list of notable unsolved problems in astronomy. Problems may be theoretical or experimental. Theoretical problems result from inability of current theories to explain observed phenomena or experimental results. Experimental problems result from inability to test or investigate a proposed theory.
The astronauts aboard the Boeing Starliner could remain in space for several months – but many wonder if they have enough food and water to survive that long.. During a recent interview with the ...
The investigation found that cold weather conditions caused an O-ring seal to fail, allowing hot gases from the shuttle's solid rocket booster (SRB) to impinge on the external propellant tank and booster strut. The strut and aft end of the tank failed, allowing the top of the SRB to rotate into the top of the tank and causing it to explode.
That has upset some current, part-time Air National Guard members involved in space missions because the proposed move would force them into the full-time, active-duty Space Force. Show comments ...
