QUOTE (marsophile @ Jul 27 2010, 11:30 AM)  I've been wondering whether they can be driven sideways. The center wheel on each side can only steer in one direction, so I don't think it can do it unless the four corner wheels drag them along. |

I have seen some prototype rovers at the JPL robotics lab that can do what you're describing (which is usually referred to as "crab-walking"). I have a photo of one called Pluto doing that in this old blog entry.

I've been away and missed the fish chat... but I feel I must retort.
Sell a man a fish, and you feed him for a day. Teach a man to fish, and you've lost a valuable business opportunity... |

In the latest batch of images on Exploratorium, I find series of images pointed in the same direction spaced about 30 seconds apart. Looking for DDs?

Do you mean the L6 pancam series? Those are super-resolution sequences, much like the previous ones. Normally they use a series of navcams to search for DDs because of the wider field of view. But I'm sure they'd be thrilled if a DD made an appearance in the L6's...

Sounds like L6 the superres, in which I saw no DDs. Tosol has some navcam DD frames, but most of them are lower priority (as usual).

Is there a super-res sequence planned of the area in which Cape York is going to appear? I'd have thought you guys would be keen to bag it

Maybe when it actually becomes visible?

QUOTE (Stu @ Jul 28 2010, 07:18 PM) Is there a super-res sequence planned of the area in which Cape York is going to appear? As far as I can tell, the direction to York should be in one of the new super-res views. It should appear in the left part of this frame: http://qt.exploratorium.edu/mars/opportuni...6M1.JPG?sol2298 It's conceivable that the official super-res will show a tiny bit of York just peeking above the horizon. |
