The inner solar system has obviously turned quite nutty. I'm heading back out.

We have some fresh pics from sol 1312 and here are the navcams for a full 360º mosaic.
It looks like this place is what's called "Site 2" on the latest update. QUOTE On sol 1306 (Sept. 5, 2007), Spirit tried again and executed the drive flawlessly! Now that the rover's two rear wheels are on top of the eastern edge of Home Plate, Spirit is in position to explore the top of the elevated plateau along its eastern and southern edges. The next planned stop is a few meters away in an area known as "Site 2," located midway along the eastern scarp of Home Plate east scarp and several meters to the west of the scarp. (If you compared the roughly circular shape of the top of Home Plate to a clock, Site 2 would be at 3:30.) Edited: Just for fun, this is an attempt to pinpoint Spirit's locations on a navcam mosaic from sol 1304.

Ooooh -- anyone else notice the arcuate and possibly pentagonal cracking in the upper surface of Home Plate in the latest images?
This used to be a cracked and tortured surface, it's been smoothed out over the megayears but it was as strong and tortured as any volcanic terrain we've ever seen on Earth. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

QUOTE (dvandorn @ Sep 12 2007, 10:56 PM)  Ooooh -- anyone else notice the arcuate and possibly pentagonal cracking in the upper surface of Home Plate in the latest images? Yes, hard to miss. To me they look like they probably are bulk shrinkage cracks - typical of dessicated, originally damp surge deposits, which almost everyone agrees these seem to be. Such shrinkage cracks also appear typical of the layered, cross-bedded sediments at Meridiani, which may or may not also be surge deposits (depending on whose interpretation you favor). HDP Don |

Good to see you around HDP - I was worried that you had decided we had nothing left to offer. Looking forward to your take on the new stuff from both Home Plate and Victoria as it arrives.

Dear guests, the "menu" for sol 1315 is "Bouillabaisse".
Delicious!  CODE 01315::p2590::18::4::0::0::4::2::10::pancam_bouillabaisse_L257R1

Sounds good. I wasn't so keen on tosols dish, I prefer mine unfractured!

I'd like to see Spirit limp her way over to the fractures in the Plate that parallel its north-northwest edge. These cracks look constructional, not dessicational, to me. And where better to examine the history of the creation of this feature than along a constructional fracture?
I know I'm getting all excited about volcanic/basaltic rock emplacement, and Squyres et. al. are on record as not being all that interested in "ho-hum, another busted up hunk of lava." But for me, this is the kind of thing geology is all about -- reconstructing the events that caused such an unusual-looking but generically common (as there are certainly a number of similar features scattered throughout these hills) feature as Home Plate. I still don't think the possibility that this could have been part of an active hydrothermal system has yet been put to rest, since I know it had a great deal of support within the MER science team when Spirit first reached the Plate... -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
