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.
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 ...
Oxygen compatibility is a critical issue in space, aircraft, medical, and industrial applications. At WSTF, researchers investigate the effects of increased oxygen concentration on the ignition and burning of materials and components used in these applications.
2 combines with atomic oxygen made by the splitting of O 2 by ultraviolet (UV) radiation. [22] Since ozone absorbs strongly in the UV region of the spectrum, the ozone layer of the upper atmosphere functions as a protective radiation shield for the planet. [22] Near the Earth's surface, it is a pollutant formed as a by-product of automobile ...
Another concern, for orbits closer to Earth, is the presence of atomic oxygen, leading to corrosion of exposed surfaces; aluminium is an especially sensitive material [citation needed]. Silver, often used for surface-deposited interconnects, forms layer of silver oxide that flakes off and may erode up to a total failure.
Additionally, satellites in VLEO are exposed to very high levels of elemental oxygen, [20] also known as atomic oxygen (AO), a highly reactive form of oxygen that corrodes most substances quickly. [21] This requires the use of special coatings to protect objects and equipment in this orbit.
