If time/engineering requirements allow, now might be a good time for Curiosity to try some astrophotography - Earth and Jupiter are making a rather lovely pairing before dawn...

Zoomed in a bit...

And on October 10th Earth and Jupiter will be even closer, with Jupiter shining above Earth...

Not saying this should be done, would just like to see the pictures. smile.gif

NOte: HUGE thanks to Ant for the Stellarium landscape file. Godsend.

MAHLI took a shot of the left middle and back wheels after inspecting the undisturbed ripple.


There are some vertical lines in that image:

It's excess column charge from a hot pixel. Hot pixels are always forming from neutron hits from the RTG.

If somebody wants to do part of my job for me, you can find and track these as they develop in all four MSSS cameras.

Interesting, I thought these were "acquired" during cruise. Are there any rough estimates on the rate new ones are expected to occur due to the RTG?

Yes. The typical rate is [ever heard of ITAR?]

The images are all out there, one can amuse oneself by looking for new hot pixels.

However: In the North East direction, there is a somewhat circular depression that is possibly a crater or perhaps a deeply eroded basin in Glenelg. I can't really place it with the overhead view.

I think it is the low area in this pic: http://petergrindrod.net/wp-content/upload...g-site-topo.png
which is just above the second g in Glenelg.

One small scoop for a rover, but another giant leap for planetary geology...

It would be great if someone could match visible features with Peter's map (see Geomorphology post 46), particularly the little 'island' at 137 27 05E, 4 35 32S which should be quite prominent.


I looked at that image and could not see any island at that location. It seemed to be a location in a basin. The problem of not being able to measure distance accurately would probably make any identification difficult, but copying the image and then drawing an arrow to point out a feature would simplify the problem for whoever tries to solve your problem.

I was referring to the small rise in the middle of the basin at the lower right there. I think (though I'm not 100 percent sure) that it's visible as the middle-distance plateau almost at eye level, just to the right of Dumgoyne. The northern 'shore' of the basin that you delineate is also in view to the left of Dumgoyne.

Just to mention in passing, I was walking near the Scotish Dumgoyne a few weeks ago, and have climbed it several times. It is a Carboniferous era volcanic plug marking the west end of a series of basalt sills which makes up the Campsie Fells (hills).

The arrival of Curiosity at Martian Glenelg is being celebrated by an event at the original Scottish Glenelg on October 20.

Glenelg, Scotland astro event

Speakers will be:
  • Doug McCuiston, Director, NASA Mars Exploration Program.
  • Bonnie Dunbar, Shuttle astronaut, who will also unveil the “Glenelg – Twinned with Mars” sign set to become a permanent feature in the village.
  • Prof John C. Brown, Scotland’s Astronomer Royal.

Let me know if anyone plans to come.

Anyone know why the mastcam images taken with the colored filters, such as the latest from sol 60 (e.g. http://mars.jpl.nasa.gov/msl-raw-images/ms...0000I1_DXXX.jpg ) are small thumbnails only? I don't think any have been full frame to date.
