Yes!!!!!!!!!! Thanks for posting that. I am glad to see that they won't squander two good spacecraft. I wonder if the light curve/rotation period of Temple-1's nucleus is pegged well enough to ensure catching the crater. I doubt it, but it would be nice. Even still, it will be interesting to see it again. While the press release statement, "It will mark the first time a comet has ever been revisited," had me screaming HALLEY FLOTILLA!, this will be the longest period of time between visits to the same comet.
I am also glad to see Deep Impact being used again. Although HRI isn't great, the spacecraft has a lot of other great instruments, and even HRI's out of focus shots are better than anything we could get of a comet's nucleus from earth. I wonder if they will try to free Stardust's filter wheel. I remember it was never attempted because it was stuck on a convenient filter, and they didn't want to risk getting stuck on something less desirable for the Wildt-2 encounter. However, with having to have NAVCAM for the sample return mission over, it sure would be neat to try to free it. -------------------- |

My guess is that it might be too risky. I was also wondering what additional information could be obtained if they were able to fix the problem. |
