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.

Super resolution isn't really going to work with two push broom images. You're likely introducing more artefacts than improvements. It looks less sharp and phoenix less obvious than the orig two images I'm afraid. So drawing any conclusion from it is unwise Yes Master ! |

Not the original poster but thanks for the tip djellison. I was looking for more information on this.

Quick question.
While I don't expect contact with Phoenix to be re-established, I'm curious as to how that would happen if it does. Is DSN time being used to ping Phoenix? Or will Phoenix just ping Earth whenever it wakes up? (If able to) -------------------- -- Hungry4info (Sirius_Alpha)

Is DSN time being used to ping Phoenix? Phoenix has no direct-to-Earth link, so I presume that any listening to be done will have to be done by either Odyssey or MRO. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

Hopefully not too far OT, but is that UHF protocol ("Electra"?) for Mars orbiter/lander comm going to be stable for the foreseeable future?
Sort of an interesting system engineering problem to make sure that future missions will be able to talk to long-lived legacy ground assets, yet still incorporate advancements/enhancements. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Or are either of the two instructed periodically to ping Phoenix? Basically, we're all waiting. But is our wait passive or active? -------------------- -- Hungry4info (Sirius_Alpha)

Active in either case - they will have to tell MRO / MODY to listen. In Lazerus mode I THINK PHX is sat there waiting for a Proximity 1 Hail. Not sure though.

Per Mark Lemmon, http://www.met.tamu.edu/mars/lazarus.html
"So, Phoenix woke up and checked: safe mode, yes; low power, yes; clock reset to pre-launch, yes; landing sensor deployed, yes. Action: try to wake up on solar power only, at whatever time of sol that solar power was sufficient. When awake, listen for a beacon on the orbiters for 2 hours. Then, sleep for 19 hours, and try again." So yes, checking on PHX will require active commanding of an orbiter. -------------------- Disclaimer: This post is based on public information only.

Alright, thanks.
Is either orbiter being used at the moment for this? If not, when are there plans to try? -------------------- -- Hungry4info (Sirius_Alpha)

I thought I heard January at one point, can't find that link now. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

January is what Veronica McGregor told me.

NASA to Check for Unlikely Winter Survival of Mars Lander
"Beginning Jan. 18, NASA's Mars Odyssey orbiter will listen for possible, though improbable, radio transmissions from the Phoenix Mars Lander..." The release includes a new HiRISE image showing Phoenix hardware with lots of frost, dated January 6. I am having a devil of a time matching up the new image to the previous ones EDIT: Crud, PSD attachment didn't work. GIF attached instead. -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Aha, I see what my problem was. I was trying to match the current backshell to the past position of the lander. The image was upside down.
New animation is here. -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Well at least one solar panel is still attached. The other looks like it's a different colour. Hopefully not a bad sign. But I'm not sure how to interpret the image.
