John Glenn reported seeing some firefly-like particles outside of his Mercury capsule during his first three-orbit trip around the Earth in 1962. This was quite unexpected until NASA scientists realized that these were frozen fluid particles being jettisoned from the Mercury capsule as it orbited the Earth. And viewing the stars and planets from space is always spectacular!
