Loss of RR is a big hit I guess. I would hope we see some 4 wheel drive testing on the flat in the ISIL just to see how much progress, if any, Spirit might make if extraction is reattempted and successful.

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.

The rover has been seen to move because of wind. Atop Husband hill, there were Navcam sequences (DD movies) where the camera moved a pixel or two. Of course, the camera didn't move - the whole rover just moved slightly in the wind. It's got quite a lot of surface area for quite a light vehicle.

Time to update spirits route map?


Not really - total progress to date would be no more than the size of the dot on the route map

MH - in LocationMetadata_update.csv - what are the various columns left to right? I could try and animate rover progress from site to site in some way using the MMB MER model, rendered from a third person perspective.

Barely enough distance to run over my iPhone - but in terms of acheivment, that would gemlike summiting husband hill all over again.

I've picked four favorites from the new batch - plus a few others from Pete - which I'll be trying to get rendered this week. Probably not as polished and pretty as the Columbia Hills anim, but they should be a bit of fun smile.gif

MSL will, as I understand it, leverage much of the code from MER. MSL carries a different faster flight computer (RAD750) which is, I think, capable of running the exact same code as the 10x slower, RAD6000 which is onboard MER.

How interchangeable this exact technique would be - I don't know.

That FL wheel might have moved much further - but progress of the rover is measured at the IMU's. Compare to the FR wheel - the FR has not moved much at all. Take an 'average' of those two to consider actual progress.

Doug, I know what you mean and you're the specialist, but M-100 yielding 7.4 cm/pixel scale at 1km distance doesn't look too bad to me.


I agree - that's superb. But it was due to be slightly better than that (10cm @ 2km I believe) - and at the wide end, be wider that the other 'eye'. But that's not the shame. The shame is that we wont have proper stereo from it. No 8fps HD Stereo driving movies or DD movies etc etc. With one zoomed in and one zoomed out, they stop being a stereo pair and creating stereo becomes a bit of a headache on the ground.

In terms of outreach, and in terms of usefulness for driving (L7 drive direction pancams, anyone) it has suffered massively.

Mastcam paper
http://www.lpi.usra.edu/meetings/lpsc2010/pdf/1123.pdf

Nice to see a finished Mastcam. Tragic to see it delivered without Zoom despite Mastcam never having been over budget.

Think about it, now the public at large can suggest an imaging target for a major spacecraft.


Not to belabour MC's point - but we were able to do this with MGS / MOC.

And they did thousands of publicly suggested images.

It's only gone public today. It's access, I believe, to the same tool used internally for target suggestion, more or less.

Probably. Like I said - no big press conference means no big news.

Things I want to try ( in no particular order )

Topography of rocks using MER MI and Pancam imagery
Height maps of MER sites using vertical projection mosaics
Produce DEM's from HiRISE of the Mars Pathfinder landing site, and the full Opportunity site ( from Eagle all the way to Victoria ) as well as Phoenix and Viking sites

It's not a 'real' thing. We've been through this dozens of times, the same as when people go 'WOAH - look at that ROCK' when it's a downlink from 7 months ago.

The left and right images are taken at the same time.

So - if it's real, it's in both. If it's an imaging artifact (cosmic ray hit etc etc) it'll be in only one image.


Now you see it

Now you don't

http://qt.exploratorium.edu/mars/spirit/na...GXP1705L0M1.JPG

Ergo - it's an imaging artifact of some kind, and not a real 'thing' on Mars.

Perhaps some sort of coincidence between the hit, and CCD readout?

Why are you assuming it's in any of them. No press conference scheduled, this isn't going to be a big discovery.
