I've just been reading Mike Mullane's Riding Rockets, as recommended upthread, and will be sad to see the shuttle go. However, I can understand why it is being retired.
On the subject of shuttle CT, I did manage to shut one tinfoil-hatter up in RL by asking them where the last crews of Challenger and Columbia are now, if they never went into space. Are they all hiding in a cupboard in Houston somewhere? |

have i missed the comet
when can i see it Quote:
http://www.scientificamerican.com/bl...-le-2010-10-22 and a sky finder guide here http://stardate.org/mediacenter/201010-comet-hartley-2. It's between Auriga and Gemini right now.
Quote:
Moon is in the way right now - the link below shows Hartley's approx position at about 1am-2am oct 25
And also - in red - it's position at about Midnight on Halloween. If you want to see it, try to catch it within about a fortnight after Halloween, as it drops down through Canis Minor and Monoceros. By Mid November the Moon will be back big and bright, spoiling the view again - and by the time the Moon is out of the way in early December, Hartley will be low to the South, around 3am-ish (to the left of Sirius) and fading fast. Position of Hartley 2 Many of the best meteor showers are assosciated with the dust trails left by well known comets. The 'Orionids' in October, with Halley's comet (1P) - the 'Perseids' with Swift-Tuttle (109P) - 'Leonids' and Tempel-Tuttle (55P) etc... Apparantly a couple of big fireball meteors seen recently are thought to have originated from the debris trail of Hartley 2. Still only a slight possibility - but if the link turns out to be correct, than a mini-shower could possibly peak around 2nd/3rd November, with the Radiant in Cygnus. (Very high to the South - almost overhead - as seen from UK around 6pm/7pm - dropping gradually to the west as the night progresses) http://science.nasa.gov/science-news...ct_hartleyids/ |

“With Spirit, we’re just waiting. We’re in the any-day-now phase. And every time I check my email, I think: ‘Maybe this will be it,’” he said during a recent interview. Hope. |

If I recall correctly, didn't the core of Halley's comet also look like a peanut?

Yes Giotto visited Halley back in 1986.
That was one of the moments that inspired my interest in astronomy. |

Weren't there 4 probes all making progressively closer passes? I remember the live coverage of Giotto's closest approach and the 'wow' of those hazy pictures of the nucleus. I don't think many of the experts seriously expected the probe to make it!

Thanks for posting that link, gemma-the-husky. The pictures from the winners and finalists in that competition are excellent. In particular, I like Edward Henry's great picture of the Andromeda Galaxy.
