Light Reflection: a brilliant fan of cryogenics venting from a relief valve on STS-122 Atlantis' ET (external tank) post-separation. Also see this handheld video of the ET, with money shots at 2:15 and 3:55. [more inside]
A tour around Discovery STS-120 and the International Space Station with Paolo Nespoli and Dr. Scott Parazynski. Tomorrow, Parazynski will be perched at the end of a robot arm and sensor boom assembly, stitching up a damaged solar array in what might be one of the riskiest EVAs since Skylab 2.
There was a lovely total solar eclipse over parts of Africa, Europe, and Asia yesterday. See the photo galleries from Spaceweather, BBC, various Flickr users, and the International Space Station.
ISS-Jupiter Transit tonight. Notable space station flyover tonight for you skywatching East Coasters: the ISS will pass quite close to Jupiter, and some of you lucky ones [coordinates|map] will even see the station briefly eclipse the planet. (Side note: Remember those days when everyone was using its radio call sign "Alpha?" Now the media just say "space station." Sigh.) East Coast, 9:30pm, I'll be outside, looking up.
