Comments on Are galvanised steel parts safe to use in space? mention that oxidation happens in the upper atmosphere because of the relatively high presence of oxygen ions.
This is apparently to the point where even aluminium needs to be coated.
- Have any spacecraft ever been decommissioned because of oxidation?
- Have there ever been oxidation problems for spacecraft beyond LEO?
Partial deterioration due to oxidation is also welcome.
The second question on spacecraft beyond LEO is not about space probes entering other atmospheres, but answers on probes orbiting or flying by non-earth bodies are welcome.
Is there even enough oxygen on worlds without plants though?
