I thought we needed a new thread to post about all of our own suggestions! I'm curious what other people are picking. I wrote about my first picks here: a spot identified in my one and only peer-reviewed publication, and some interesting-looking fluvial features.

I inquired about what would be a reasonable turnaround time to expect on HiWish images. The shortest conceivable time between request and image being delivered to the PDS is two months, which is pretty amazing when you think about it, but in reality the lag will probably be longer. Images get delivered to the PDS on a monthly basis.

I really wish to have a second/third/fourth look to Mars caves region (Arsia mons), but diagonally rather than horizontally, both to better estimate caves depth and to figure out if "normal" caves with vertical entrance exist.

Similarly, I'd like to see verification of the 3D structure of the putative natural arch.

I've gone for some Barchan Dunes previously seen in March 2008 - to monitor for dune migration and evolution, particularly as there are some hugely long tendirl like dune features that might hint at shifts in prevailing winds. http://hirise.lpl.arizona.edu/PSP_007676_1385

I'm temping to try and point out the lack of colour coverage over Eagle Crater (Backshell, parachute, lander) and the Spirit Lander / backshell - apart form monitoring what the parachute's are doing in the wind, and the evolution of the impact crater made by Opportunities back shell, I'm sort of struggling a bit. I need a scientist to justify it with photogrammatic reasons.

I propose photographing numerous channels east of Hellas.

Their lower parts sure look a lot like ancient rivers and even delta sedimentation (for example, http://www.google.com/mars/#lat=-41.450961...mp;map=infrared - note completely covered over largish crater a bit to the left from center). Ancient water history, yay!

Going "upriver" we eventually reach highlands and what looks to me like volcanic plains created by Tyrrhena Patera eruptions.

Unless I am mistaken again and this terrain is not volcanic. It has confusing "young" look with crisscrossing ridges:

http://www.google.com/mars/#lat=-28.149503...mp;map=infrared

On one hand, it looks like very wide lava flows. OTOH, lava flows covering territory much bigger than Olympus Mons base? Is this realistic?

Imaging the Spirt Lander/Backshell/Parachute/ is DONE smile.gif

"ID 43290
Title Spirit Lander Backshell Heatshield and Parachute in color
Suggester djellison
Suggestion Date 2010-01-31
Number of Observations 1
Primary Theme Future Exploration/Landing Sites
Secondary Theme Landscape Evolution
Retired By ESP_016677_1650
Date Success 2010-02-11"

If I'm reading that right - the time between my suggestion and the image being taken is just 12 days. I'm going to make the assumption it was planned for anyway.

Or maybe it's not actually been taken yet - it was just added to the list of future observations on that date.

Beyond awesome, can't wait to see it!

That will be a very interesting image. Maybe we'll see one of those pesky Gusevian Gorillas pulling bits off it... rolleyes.gif

What does "Retired By ESP_016677_1650" mean? I'm reading that as saying the requested observation already was done so it won't be repeated, but it's not really clear.

It means it's been scheduled as an observation, so the 'request' to take the image is now retired.

I don't know if that image ID is in the past, or the future, so I don't know if it's been taken or not. I can't find a place to tell me the current orbit number to figure it out.

Just a little explanation about suggestion retirement: We try to retire target suggestions as early as possible in the planning phase. Since we have multiple cycles being planned simultaneously we want to make sure that once a target has been picked up for planning in one cycle, it won't get picked up again by another. So suggestions often get retired several weeks before the observation is taken.

As for your target, Doug, we do have it on the ground, but I think we will probably unretire it. ESP_016677_1650 fell a little too far east of the Spirit landing site area, but covered enough of your suggestion footprint to cause it to be automatically retired.

Ooo - does that put that color section inbetween my proposed target, and the previous ones straight over the columbia hills and Spirit's current location? We could end up with most of the traverse being documented in color, which would be very nice (and sort of a sensible thing to do anyway I would have thought)

Opportunity did us a favour by driving south, down HiRISE CCD paths.

Thanks for the details - I'm sure the selecting planning and sequencing is more complex than I'm imagining it. Keep us posted!
