Moon emoji

So apparently a bunch of astronauts just re-entered the atmosphere. Or left it. I'm not sure. About six months ago I programmed my partner's If This Then That account to text her the words "Moon emoji" every time one (or maybe both) of those things happened. We can't remember which. She just got the alert three times in a row, so either (a.) three astronauts just came home, (b.) three astronauts just launched out of the atmosphere, or (c.) some combination of astronauts just passed the barrier of the atmosphere and there has been a net change of +/- 1 astronaut in space.

So, in conclusion, the number of people in space right now just changed by either one or three. Most likely three.
