I thought it was time to start a new thread on Stardust's flyby of Tempel 1, the first time a comet receives a second visit from a spacecraft one perihelion later.
There was an interesting story about this on Spaceflight now recently http://www.spaceflightnow.com/news/n1012/23stardustnext/ note that the flyby will be around 23.30 eastern time on 14 February, so thinking in GMT it will not happen on Valentine's day. Stardust should have started imaging Tempel 1 twice weekly in mid-December, but there is nothing yet on the mission site http://stardustnext.jpl.nasa.gov/index.html see also http://stardustnext.jpl.nasa.gov/mission/m...tatus10_q4.html for updates on the mission status |

While we are waiting for our Glorious Leader to take the stage, may I take this opportunity to remark how unbearably boring NASA TV is 99% of the time - especially immediately preceding live events.
EDIT - it's on now 8:20 pm PST -------------------- If Occam had heard my theory, things would be very different now.

Its not PBS or the BBC, but it also receives a really small budget in comparison, and still is able to put on informative shows, albeit with a certain cheese factor.

Well done, Doug!

Closest approach done! (my heart jumped when that guy said 'impact').

This is really a fantastic tool. Curious, is the positioning of the comet accurate? The last I was aware, the comet movement wasn't known well enough to predict it at that time.

The orbit of the comet is actually very well understood. The big unknown is its rotation, though they have a pretty good idea based on light curves.

Not at all surprising, imho. Outbound, the spacecraft is heading into the "tail" IIRC.
Edit: 181 km was closest approach. -------------------- -- Hungry4info (Sirius_Alpha)

This is really a fantastic tool. Curious, is the positioning of the comet accurate? The last I was aware, the comet movement wasn't known well enough to predict it at that time. Well, clearly they are trying to center the comet in the frame so they will point to where they think the comet will be to the best of their knowledge of the predicted trajectory of both the comet and the spacecraft. Though obviously, when the real images, that doesn't mean the comet will actually be in the center of the image. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!
