Reviews of space-themed books for kids ages 7 and up
OK, this is my last pile of book reviews for this year: a collection of good books for kids older than mine. I've split them into two age groups: 7-11 and 12+, though of course there is likely some overlap, depending on the kid. Be sure also to... More»

One-astronaut game of baseball in the International Space Station
This video made me very happy just now. Satoshi Furukawa's pitching form is impeccable. Space exploration isn't all work. It isn't even mostly work. Sometimes we do it because it's (literally) awesome; and sometimes, because it's so darn much... More»
