And this is a quick go at the last image of the Martian surface taken by Phoenix.

Great mission - it's been a fantastic ride over the last few months. Thanks to all involved. Goodbye Phoenix.



This unremarkable pair are sitting at the bottom of my MMB directory:

And the sol 1700 drive



James

Hey Doug it's been a while since I've seen any colour mosaics from you - nice to see.

Here is my attempt at both the 1702 and 1704 drive direction mosaics.

1702


1704


Both images link to the same blog post.

James

Yeah, if you look at my Hi-Res analysis image you can see a nice blue path around the edge.

Split posts on making colour images from monochromatic images taken under differing illumination to a new thread.

Ture, but this is an interesting idea, and that one of the lander is lovely whatever it really shows, great work Fran.

Split to a new thread.

Phoenix Lazarus mode worked and she was contacted successfully on Thursday evening, according to this article linked from the Phoenix twitter feed.

Hooray!



So are the pictures not saved on board at all?

Looks like another drive is happening tosol (1716).

I wonder if we'll see them turn the wheels to try and control the yaw caused by the dud wheel - the turn does look a little worrying from the drives so far.

Good point about the nearby point where we know Spirit can climb HP I had been lead down the same line of thinking as Doug before now.

James

Some data has hit the database - if the numbers can be believed then it was a <1cm drive. Quite a contrast to Oppy!

Still heading up the slope

I had a quick go at trying to match the ripples and the outcrops ahead to the HiRISE and it looks to me like Tesheiner's position is bang on.

(Not that I'm surprised )

And here is our 'Spirit pancam image of the week' in context of the rest of the Bonestell pan that has been downlinked so far. (hugely reduced in size at this time)



James

FYI - Here is Tesheiner's route map with my colour coding. Dangerous seas ahead...

Yes, the plan for a long time has been to head over to von Braun after winter. It was expected that Spirit would have to descend off HP from the winter haven, but we heard a while back that they were going to attempt to climb back on top where the terrain is easier to drive on and also a lot shorter to get across to VB. From the first bump it's looking good for the shortcut.

That is GREAT news that Spirit was able to bump UP the slope. Looking good for the short cut across Home Plate.

Looks like Richard Noble and Andy Green are back and planning to break 1000mph!

A rocket AND a jet engine!

Another sol, another 127m WSW...

"Later this week" would be tosol (146) if the tweet from Phoenix 12h ago is anything to go by...

It's been a long time since I last worked with the tracking data - but if I've got this right, it looks like tosols drive was about 130m WSW (maybe a little more as the site ID was reset at the end) - that is directly away from Victoria.

Goodbye Victoria - Onwards!

James

Now we're about to get going, and after posting a section in another thread, I thought it would be of interest to post the section of my latest terrain map overlaid onto the HiRISE image for the land that we are about to traverse. The colour overlay is now at 4m/pixel resolution, which is comparable to the larger ripple size.



James

Well spotted Phil.

I've made a polar image of the 1683 drive direction images and overlaid it onto my latest driveability image (considerably higher resolution than anything I've posted on UMSF so far) showing how the images point straight at the prominent SSW 'ray' (South is at the top, pancams are rotated using tracking data, position is approximately Tesheiner's route map position)

In the second image I've pointed out a few features that I have (very tentatively) matched up.



James

I've been getting a little behind worrying about the ripples further south. Just catching up with the last couple of colour mosaics.

Sputnik



And Cape Pillar



(Both images link to the same page)

James

Here is my version of the southern part overlaid onto the HiRISE at 1/4 (and smaller if it's too big )

Of course I could be entirely wrong, that just seemed like the most likely explanation to me, I'm not sure I've ever read anything about it. I'm sure there must be some real research into the phenomena out there, it's probably much more complicated! Any opticians out there?
