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.

It's the way the Lazarus mode works. The source is the Phoenix mission team at JPL (originally from Chris Lewicki and Barry Goldstein). The chief telecommunications engineer for the Mars Exploration Program, Chad Edwards, who led the January listening campaign, confirms: "Phoenix's fault mode would have it transmit to any overhead orbiters - without needing to be hailed - during portions of each 2 hr wake-up session (in between 19 hr hibernation periods). We do not need to hail Phoenix to trigger that behavior." |
