Last night Steve and I walked to the park to look for the International Space Station. We weren’t sure where to look. We spent a few minutes theorising about orbits and speeds and the direction of the Earth’s spin, and then spotted it mid-conversation. It was very bright, and moved right over the top of us. Double bonus: it was going approximately the same way we’d figured it would be 🙂 It was really cool to look at it and realise that there are people up there in that thing. What were they doing up there? Sleeping, eating dinner, working? Pretty cool.
