Doug just said in another thread that he was looking for Phoenix in the new images and couldn't find it. Well, I love a challenge. So here it is:
Close-up: (REMOVED - SEE LATER POST) Context: (REMOVED - SEE LATER POST) Note that map-projected HiRISE images at this latitude are in polar stereographic projection, not a cylindrical projection. North is at the left. You might not believe this, but by blinking layers like Clyde Tombaugh I think I can match numerous points, not just the hardware. EDIT: I was a bit off. Correct locations are shown below. Phil -------------------- ... because the Solar System ain't gonna map itself.

Does anyone know what the cost/downside is of having Odyssey listening for Phoenix? If there is no cost, why are they waiting until the 18th? Why not start listening immediately whenever Odyssey passes over the Phoenix site? (that way we could determine if Phoenix made it throught the winter as soon as possible and maybe get interesting science results sooner).
Presumably they are delaying the start of the listening and then doing it for only 3 days because using the radio receiver on Odyessey must interfere with other instrumentation or data relay or power consumption or what? Does anyone know what makes using the radio receiver non-zero cost to operate? Even if Phoenix does not have enought power now to wake up yet, continious listening (assuming it can be done for 'free') would allow us to know *when* Phoenix wakes up (if it ever does which is unlikely) which would be interesting to know. |
