The Long Duration Exposure Facility (LDEF), which was retrieved in 1990 after spending 68 months in LEO, revealed that space environments are very hostile to many spacecraft materials and components. Atomic oxygen, which is the most prevalent atomic species encountered in low earth orbit, is highly reactive with plastics and some metals ...
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.

It is a critical issue in space, aircraft, medical, underwater diving and industrial applications. Aspects include effects of increased oxygen concentration on the ignition and burning of materials and components exposed to these concentrations in service.
2 in space applications, such as in some modern space suits, or in early spacecraft such as Apollo, causes no damage due to the low total pressures used. [117] [137] In the case of spacesuits, the O 2 partial pressure in the breathing gas is, in general, about 30 kPa (1.4 times normal), and the resulting O
Two days after liftoff, on April 13, 1970, an oxygen tank in Apollo 13’s service module exploded. The explosion crippled the spacecraft, leaving it without most of its oxygen supply, electricity ...
All space tethers are susceptible to space debris or micrometeoroids. Therefore, system designers will need to decide whether or not a protective coating is needed, including relative to UV and atomic oxygen. For applications that exert high tensile forces on the tether, the materials need to be strong and light.
[6] [7] Researchers at University of Minnesota and Pennsylvania State University are performing the atomistic simulations to obtain accurate description of interactions between atomic and molecular oxygen with silica surfaces to develop better high-temperature oxidation-protection systems for leading edges on hypersonic vehicles.
S383 is also more resistant to atomic oxygen encountered on orbit prior to berthing. [17] The Type II was used to launch small elements in the shuttle payload bay while bolted to an ACBM or to similar flight-support equipment because the V835 material is more resistant to the damaging effects of scrubbing under vibration.
