Understanding Corrosion in Space

Corrosion is typically associated with terrestrial environments where oxygen and moisture play pivotal roles. However, space presents a unique set of challenges. Space corrosion can occur due to exposure to atomic oxygen, high levels of radiation, and thermal cycling.

Causes of Corrosion

Atomic Oxygen: In low Earth orbit, spacecraft are exposed to atomic oxygen, a highly reactive form of oxygen that can erode materials, as explained by Nature.
Radiation: High-energy radiation in space can degrade materials, leading to structural weaknesses over time.
Thermal Cycling: The extreme temperature variations in space cause expansion and contraction of materials, potentially leading to micro-cracks and subsequent corrosion.
