There are a lot of us here on Earth who blog about space, but as far as I know, there's only one person in space who blogs about Earth: Sandra Magnus. She's on board the International Space Station... or at least, she will be for a few more days. When Discovery returns home, it'll have her on board, taking her down to Earth where she'll walk on a planet for the first time since November of last year. She just posted a beautiful entry where she takes the time to sit and watch the Earth roll underneath her as she passes silently over it at 8 kilometers per second. It's vivid and wonderful, a description of the view that I hope the next generation of humans will find commonplace. For now though, it's a rare gem, so enjoy it.
