Imagine being Scott Kelly, the astronaut who on Tuesday night touched down his landing craft in Kazakhstan after spending the previous 340 days aboard the International Space Station. It was longer than any human being has ever been in space. Imagine that. Try to remember last March 25, the day Kelly launched, how long ago that feels, and remember everything you’ve done since then: All the people you’ve seen, all the meals you’ve eaten, all the times you’ve looked at a tree, or felt sand beneath your feet, or the wind on your face, all the nights you’ve slept in your own wonderful bed. Imagine if that whole time, all those many days and nights, you were instead orbiting 250 miles up above the Earth, moving at nearly five miles per second, encased in a hunk of metal.
