Here we go! New Horizons is poised for launch today, and I'm watching the feed on NASA TV to keep my eye on the status of the mission. There are some clouds in the sky, which should be thinning over the next couple of hours. No rain is predicted. There are some winds with gusts up to 30 knots but the announcer seems not to be concerned. Here's a lovely recent photo of the launch vehicle; I'll get a timeline posted here shortly...
New Horizons' Atlas V Rocket
On January 15, 2006, the Atlas V launch vehicle carrying the New Horizons spacecraft was moved to its pad, on Complex 41 at Cape Canaveral.
