Nice drive! (2692)

Huzzah!

Besides the obvious fact that the front Haz's (after the Michael Jordan spin move to have us drive forward rather than backward) show Tisdale 2 right under our nose, the other indicator we were expecting of having made it was that the post-drive navcams wouldn't be able to see Tisdale 2. And whatddya know.

And a nice look at a light-colored rubble pile (or roughed up rock) I think you mention a few posts back.

If this is all that's left of a rock, try to imagine how long it took to turn it to this pile of light dust...

Is it too cold on Mars for diurnal heating/cooling cycles to have such an effect?

Here's a paper on that subject: Simulating weathering of basalt on Mars and Earth by thermal cycling
"...diurnal cycling of temperatures on Mars can cause deterioration of rocks with a pre‐existing stress history, as would be typical for surface rocks here...
....dramatic failures of basalt boulders could occur under current Martian conditions, apparently due only to thermal cycling."

Here's an animation of the sunset on sol 2666 that I hacked together tonight. I was going to try to make a little YouTube movie out of it, but I've run out of time to work on it for now, so I've just put it into QuickTime format. Since it's made from the uncalibrated JPEGs (L7 and R4 filters) the color should be regarded as a whimsical guestimation at best.

Hey guys, I'm just checking in. Just read this whole thread, probably gonna be lurking in this thread, possibly contributing a bit. Very nice images in this thread. Good to see some familiar people as well as new faces, been a long time since I've been here. Looking forward to Opportunity's adventures in Endeavour Crater.

Still, I gotta say I read John's post and I was all, "what, you can say all that from one low-res JPEGgy color photo?"

Belated lame self-justification- I was gone all weekend and not thinking about Mars at all.

I only said it *looked* like scoracious lava with xenoliths- I've seen similar things in lava fields in the Arizona desert. Looking more closely, though, Munro is clearly a beautiful breccia like the other rocks around here. Can't wait for the close-ups!

Wow, they topped off the 2692-2693 Navcam panorama with some subframe images on 2695. Unfortunately my panorama export feature isn't good enough to handle subframe images, but it looks nice in MMB, thank you.

Matt Lenda

Aug 24 2011, 03:28 PM

Indeed. You'll notice that the previous Navcams were clipped on top because of the terrain being higher on that side. We sequenced these Navs to fill out missing bits and get a little bit of sky.

I made this vertical view of the current site, using the 360deg. mosaic by jvandriel, and tried to include all rocks visible on the near and mid range, labelling the ones which have already been "christened" by the mission.

sols 2690-2696, August 18-24, 2011 Opportunity Studies Rocks on Crater Rim

Opportunity has begun the in-situ (contact) investigation of rocks around the rim of Endeavour crater.

On Sol 2690 (Aug. 18, 2011), the rover began the approach to a large ejecta block, named "Tinsdale 2" with a 4-meter (13-foot) drive. On Sol 2692 (Aug. 20, 2011), Opportunity completed the approach to Tinsdale 2 with a turn-around to face the rock and a short 2-meter (7-foot) forward approach to the target. On Sol 2694 (Aug. 22, 2011), Opportunity started the multi-sol, multi-target in-situ (contact) investigation with a Microscopic Imager (MI) mosaic of a set of surface targets collectively named "Timmins," followed by a placement of the Alpha Particle X-ray Spectrometer (APXS) for an overnight integration. On Sol 2695 (Aug. 23, 2011), the rover collected another MI mosaic on a different target spot, again followed by an overnight APXS integration. On Sol 2696 (Aug. 24, 2011), Opportunity did it again with another set of MI mosaics and an APXS integration.

A belated thanks for this, Tesheiner, and to all the mosaicers/anaglyphers out there - I'm just doing my catchup after some travel. This really does feel like a new mission - rock maps remind me of Phoenix!

Oh yeah - "icing on the cake" was a good one!

I don't really promote it, because it's not user-friendly or even finished. Only if you're really serious about downloading and viewing MER images outside of JPL. Anyway, back to the topic at hand.
