There is an Opportunity briefing December 4 at 10:30 am PT. 1:30 EST 18:30 GMT/UTC
Archives should be found at this link:

This is being streamed by AGU and I haven't been able to determine if it will be archived. Although I imagine it will.

Participants:
Steve Squyres, principal investigator for Opportunity, Cornell University, Ithaca, N.Y.
Diana Blaney, deputy project scientist for Opportunity, NASA's Jet Propulsion Laboratory, Pasadena, Calif.

NASA’s Mars Exploration Rover Opportunity, working on Mars since January 2004, has spent
recent months examining outcrops in an area on the rim of Endeavour Crater. There, the rover
has found unusual textures and orbital observations have suggested the possible presence of clay
minerals. This briefing will offer an update about what has been found so far during these rover
investigations at “Matijevic Hill” on the crater’s western rim and outline plans for continuing
work by Opportunity.

Anything that's streamed by NASAJPL on UStream will always be archived there.

Thanks for posting info on the Opportunity briefing, stewjack. That definitely made my day.

There is another briefing/lecture anounced on the AGU website.
Whipple Lecture: P33F. Clues to a Hot, Wet and Violent Ancient Mars: Spirit in the Columbia Hills and Opportunity at Endeavour Crater ? (Video On-Demand) ?

Not certain if non-members can access Video-on-Demand, or if the Whipple Lecture will even be streamed live! I am not a member of the AGU. I just searched the website out of curiosity.

5 Dec 2012 2:40 pm - 3:40 pm (pacific time I guess)

Did Steve in that conference ever mention how long the APX takes to do a run nowadays? From the amount of sampling they plan on taking, I think Oppy could spend a -lot- of time being still during the coming months.

The material used in the APXS is curium 244, which has a half-life of 18.1 years. So even after nine years the instrument should still be about 70% as effective as it was upon landing (ignoring other kinds of degradation). It's use of the Mössbauer which has been suffering in recent years- it uses cobalt 57 which has a half-life of only 271.8 days. AFAIK they will no longer be using it.

Would love to demand that video Anyone know how to see it ?

I'm not certain why they would call it "video on demand" when it seems to not be available at all. You would think that if you were required to be registered and log in they would tell you so. Maybe I missed something at the web site.

The good news is that past lectures have been archived here. I wonder how long it will take for the archive to be updated with the 2012 lectures.

Steve said the Mössbauer is dead, they ran out of Cobalt a long time a go.
He skirted the question about the APX time, but it's working pretty much as normal, as other people have pointed out the half life of it's source is 18.1 years.

AGU videos are at http://www.ustream.tv/nasajpl2

I believe the 'video on demand' are available 48 hours after???

the Dec 3rd and some Dec 4th vids are now available by clicking on the meeting link.

Note: The actual lecture starts approx 13:00 min into the video

That was fascinating. Squyres is a great speaker, and that lecture explained a lot of things that I could see in the imagery but couldn't quite make sense of. I feel a lot better knowing that they haven't figured it all out yet, either.

Time for a new thread (this one was becoming too big). Please keep posting here anything pre-sol 3153 but use the new one for the latest stuff.

BTW, the former thread "East side of Cape York" has been split in two. One with the former name covering from Whim Creek to Matijevic Hill and another one (this one) for the first survey covering from Kirkwood to Sandberry.

The above area near Kirkwood from a Sol 3066 pancam image has some interesting accumulations of spherules. In particular, it seems to show something like "berry bowls" of newberries. Is that surface too rough to be used for IDD work?
