Quick look at some features just ahead in a stretched view of the Navcam frame.

James tweeted: "Oppy sol 3310 - Took pancam images of Karratha & Corunna Downs. Then drove 95m SW along Cape York. "

Do we know yet which features these are?

We haven't seen many images come down yet, so it's hard to be sure. Here's my estimate based on what we do have, though. This is seen from site 170/0114 (sol 3308), below "Kirkwood".

I hope we'll see some more images soon, so I can find out if I was right! (And so we can have some more images.)

Edit: Oops, mispelled "Corunna" in the image. Lack of coffee, etc.

Thanks, Ant. Isn't it great to see drive-direction pancams again?

Based on the drives so far, it looks like the plan may be to hug the "coast" of CY, just inland, rather than driving straight for Solander Point.

Actually, I'm wondering if she will do a quick stop near Odissey to image those old tracks around it.

According to the last Planetary Society MER update:

"We calculated a rapid transit... " Arvidson informed. "....This route allows for a short stop at Nobby's Head so that the rover can take some stereo images of the northern side of hill for engineering characterization of slopes, just in case we need a possible bail-out location for winter, but other than that it's a path that will take Opportunity to Solander as quickly as possible..."

Just bck to Opportunity's driving record, there's a nice little poster on vehicle driving distances (Moon and Mars) over on i09.

Wow, thanks Centsworth - I wasn't aware of that site. Looks like a good source for geo maps, place names, etc.

That's from a full press release.

This looks like a good place to add a note of caution about Lunokhod driving distances. They will have to be recalculated based on the LROC images. When the actual Lunokhod 2 tracks are compared with the original Soviet-era map, it looks to me like they landed slightly north of the expected location, drove a bit further south than they thought, then east, and finally ended up further north than they thought. Some extra distance will probably come out of a recalibration of the drives (maybe they allowed for more wheel slip than actually occurred). A new mapping effort is under way at MIIGAiK - they already did Lunokhod 1 and are working on Lunokhod 2. Maybe by LPSC next year we will have a result. Just a caution - we might break the record and then have to break it again!

Don't just read that great site by Larry Crumpler - those images, especially the maps, can stand a considerable amount of enlargement. Lots of good stuff! Too bad there doesn't seem to be an archive of past reports like these.

Did you also notice that we (I on the Spirit & Oppy Statistics) used to get 35890 for Apollo 17 rover and this is also used on the New Mexico Museum's but Nasa says 35744...and tthey can't be wrong rolleyes.gif
Phil, do you think all Moon driving distances will have to be reevaluated?
Thanks

Apollo should be much better than Lunokhod because they had high resolution orbital images and lots of backup position data. I would not have expected much change for Apollo distances. I will look into the difference in those numbers.
