  2. Atmospheric escape - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_escape

    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.

    August 29: An air leak caused by a 2 mm hole is discovered in the docked Soyuz MS-09 spacecraft. Astronauts initially patched the leak with Kapton tape, and later sealed with an epoxy patch. [49] A spacewalk was performed on December 11 to cut through the insulation layer on the outside of the spacecraft for inspections and sample retrieval.

    Corrosion in space is the corrosion of materials occurring in outer space.Instead of moisture and oxygen acting as the primary corrosion causes, the materials exposed to outer space are subjected to vacuum, bombardment by ultraviolet and X-rays, solar energetic particles (mostly electrons and protons from solar wind), and electromagnetic radiation.

    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.

    Cartridge heaters are usually a quarter-inch or less in diameter and up to a few inches long. Another type of heater used on spacecraft is the radioisotope heater units also known as RHUs. RHUs are used for travelling to outer planets past Jupiter due to very low solar radiance, which greatly reduces the power generated from solar panels.
