Just imagine what could be done with a better base map and an automated process to extract the route points from the tracking web... blink.gif


Indeed blink.gif

There is another possible issue with the maps.
If you compare the images I use on my route map (R15-00822 and R22-00640) they simply don't fit each other 100%, and it's not an issue of scaling or rotation. The reason is that MGS doesn't take a due vertical shot but at an angle, and those two images were taken at different positions. It's the same as trying to fit two images of a stereo pair; they won't.


That's true, I hadn't thought of that, thanks.

As for Mars 24, it does show landing sites but only the NASA ones.


That's not true, it includes Beagle 2 and Mars 2/3/6, plus a whole load of surface features.

I think one reason may be the map scale --- there was a discussion on this issue a long time ago (it should be somewhere here on the forum). This one is assumed to be at 0.5m/pix but I'm not 100% convinced of that.


I don't think that is a problem, I can't see any obvious scaling or rotation to improve the match.

QUOTE (Tesheiner @ Apr 27 2006, 06:24 PM) *
Another obvious reason is the unaccuracy of my measurements. smile.gif


I'm not so sure this is a problem either, your positions look good to me (wrt the outcrops) smile.gif

It may be there is no real problem, I think I need to compare more maps. I'll get back to you...

Right on the money, James.


Well, not quite. It's close, but I don't understand the discrepency between the distances I get from the tracking data and that on your map.

I'll do some more tests...



I've overlayed the route derived from the tracking data over your map (matched at the sol 794 point (the origin of site 69)).

What's interesting about this map is it shows the different driving techniques. The 'solid line' of red points shows autonav regions (around 1m between each point) and the more widely spaced points (with yellow lines between) where they are more confident of the terrain (near the start of the sol) and are doing 6-10m (blind) drives before checking for slippage etc.

Celestia is hardly LITTLE though! laugh.gif But well worth it if you can get it running.

Seeing your comment "daylight, landing sites etc." made me immediately think of Mars24 which does that at least.

If my understanding of the data tracking site is correct, then the drive to 69KE on sol 800 was 30.8m on a bearing of 112 degrees.


Putting us here

I Think... I hope when the images come through Tesheiner can confirm this.

I like the look of this for the coming sol pancam.gif :

CODE
814 p2280.05 52  0   0   52  0   104  pancam_McMudro_pan_col_1_L234567Rall


The first column of a pan in all filters smile.gif (I would assume a 360 smile.gif )

Not only that, but with 52 images that means it's going to be 4 frames high! smile.gif smile.gif

Finally caught up with myself after my holiday. I've added a handful of small colour mosaics taken by Spirit going back to sol 774 (and redone one from 729) to my site.

The most recent one from sol 800...

Up to now we've been using the "Nasa Picks "juno" As Next New Frontiers Mission" thread. But I guess we're well past the 'picking' so a new thread is in order.

Bruce posted a link to a good pdf on the mission: http://trs-new.jpl.nasa.gov/dspace/bitstre...4/1/05-2760.pdf (at the time only visible in the US, but I had no problems here in Oz just now...) for a nice bit of background.

The resulting maps that I quickly put together today (with Microdem) I thought be worth sharing. I was unable to use a mars projection, so the results are not perfect, but all things considered, still reasonable.


These are very nice, good job.

Any chance you could make one showing the component of the slope in the north-south direction?

Cheers, James

Last month when I rang the Imax at Darling Harbour they told me it wouldn't be starting until later in the year - they never said next month! blink.gif So it's really starting tomorrow! Can't wait to see it. Anyone else going? Here's the session times at the Sydney Imax site and the 2nd link has a review. Hope to see lots of marsaholics there. smile.gif


Wow, thanks for the heads up! I'll cirtainly be going very soon, would be great to have a UMSF.au outing to see it sometime smile.gif

No problem, the more use my pictures get the better.

No - that's real - we saw the same 'ripple' pattern up close some time ago smile.gif

Could be, but it's not the same effect seen from quite far away.
See that zig-zagging -- I've edited the previous crop and added some drawing.


I'm pretty sure thats the real structure of the dunes/ripples. Attached is a .png of the raw .jpgs in that region with just contrast/brightness adjustment. Those markings are in all the filters and look like real dunes/ripples to me.

i'm gonna add this to the this thread as it is an access problem:

since the most recent invision update UMSF crashes safari on my mac, and i mean all the time. nothing else (and i get throught a lot of other stuff) crashes safari but UMSF.

i'm currently running osx 10.3.9 (yes yes i know i need to get 10.4) and safari version: 1.3.2 (312.5).

anyone else having this problem?


I've had no problems using 10.4.5, Safari Version 2.0.3 (417.8), but that doesn't really help you does it.

It has crashed Firefox (1.5) on my Linux box, but only once.
