Roamy here. This one took me a bit to wrap my brain around. This photo was taken from the International Space Station and is of Atlantis’ reentry. From the forums on nasaspaceflight.com, the photographer was astronaut Mike Fossum, sitting in the ISS Cupola. Atlantis was crossing Central America, probably El Salvador.
That’s the plasma glow from re-entering the atmosphere. This one is blurrier (long exposure), but I like it better than the official one.
Dropped like a rock, didn’t it?
