I think you'll find that this site has more value for watching the progress of the Mars Rovers: http://marsrovers.nasa.gov/home/

Has opportunity died? It doesnt seem to have done anything for days, and now we've had no pics for 2 days.

There's no report of any problems. I believe Oppy's currently in restricted sols (i.e., the timing of the Martian day is such that they can only command it every other day), and the Deep Space Network is having some issues. The folks over at UMSF think that Opportunity will get to the rim of Victoria in another few days.

There is less of a hurry at this point. I DO want to see the first pan of the inside of Victoria, but Opportunity will be cruising around the outside of the crater, snapping images from different angles, and studying the ejecta blanket, for a long time. Perhaps until next summer. We'll get lots of looks.

Big hole in the ground ahead for Opportunity. Navcam, September 19.

Other Navcam shots of beginning final approach to Victoria Crater at Exploratorium.

It's great to see the rim finally. It won't be long till we see some long awaited panoramas.

Opportunity's First Glimpse into 'Victoria Crater'

Quote:
A drive of about 60 meters (about 200 feet) on the 943rd Martian day of Opportunity's exploration of Mars' Meridiani Planum region (Sept. 18, 2006) brought the NASA rover to within about 50 meters (about 160 feet) of the rim of 'Victoria Crater,' the mission's long-term destination for the past 21 Earth months. Opportunity reached a location from which the navigation camera on top of the rover's mast could begin to see into the interior of Victoria. This mosaic of five frames taken by the navigation camera reveals the upper portion of interior crater walls facing toward Opportunity from up to about 850 meters (half a mile) away. The amount of vertical relief visible at the top of the interior walls from this angle is about 15 meters (about 50 feet). Victoria Crater is about five times wider than "Endurance Crater," which Opportunity spent six months examining in 2004, and about 40 times wider than "Eagle Crater," where Opportunity first landed. The great lure of Victoria is the expectation that a thick stack of geological layers will be exposed in the crater walls, potentially several times the thickness that was previously studied at Endurance and therefore, potentially preserving several times the historical record.

Are those hills I can see on the horizon? The next goal for Opportunity (assuming it ever leaves Victoria)!

I doubt Opportunity will ever leave Victoria. There'll be enough work to do there to last a Martian year.

Animated Elevation Model of 'Victoria Crater'

Quote:
This animation created by the U.S. Geological Survey uses a digital elevation model generated from computer analysis of three images taken by the Mars Orbiter Camera aboard NASA's Mars Global Surveyor orbiter. The vertical dimension is not exaggerated relative to the horizonal dimensions. The crater is about 70 meters (230 feet) deep.

First Pancam shots of Victoria rim up at Exploratorium, September 20, like this one.

On the assumption that there is a rover-friendly path in...

I believe you are right. But then again, I once thought the same thing about Endurance. But this time the job is so much bigger and the rover so much older.

And there is factor beyond the mere life of the rover. With Endurance there where ample interesting stuff to lure the mission managers to send Opportunity on the road: the heat shield, a bunch of crater, a change of terrain that the Etched Terrain represented, and if luck held Victoria. Is there really anything interesting enough that is close enough that after a couple years at Victoria to lure mission planners to send Opportunity on the road again as opposed to just doing even more work in Victoria?

A lot will depend on whether they can get the rover down into Victoria. Any idea on how far away those hills will be?

Look here for a picture that tells the tale.

Keep in mind that Victoria is about half a mile across. This is about four miles through etched terrain (dunes), and then another three or four to the hills. All told this is a little longer than all of the travels so far.

Re Harlequin:
On the unmannedspaceflight boards, a few people are talking about a giant crater rim several more kilometers away from Victoria. However, this crater is both large and poorly-preserved, more like a concentric series of hills rather than a classic crater. We'll see, though.

Considering that Endurance is visible above and a little to the left of Victoria, it looks to me as if just the trip to mini-Endurance would double Opportunity's travels so far

Default Spirit Sol 18 Anomaly

Over at the Planetary Society Blog there is a nice article by guest blogger Mark Adler about the software problem Spirit had early in its mission. Adler was the Mission Manager for Spirit from launch through its first extended mission and he's written an account of what happened to Spirit and the steps they took to correct it. It's nice to see the insiders perspective. I especially liked the humor in the naming of the special shutdown command.

There's not a whole lot of new information, but I thought the resident MER enthusiasts would appreciate it.

The dropout rectangles in Opportunity's sol 947 pictures are far freakier than usual. I hope nothing's gone wrong with the transmitter.

Mars rovers get another one-year extension:

Quote:
NASA's Mars robotic missions are performing so well, they are being prepared for additional overtime work.

The team operating the twin Mars Exploration Rovers, Spirit and Opportunity, since January 2004, won approval for an additional year of exploration. NASA funded the extensions on recommendations from an outside panel of scientists. NASA also is adding two more years of operations for Mars Global Surveyor, which has been orbiting Mars since 1997, and the Mars Odyssey orbiter, at the red planet since 2001.

These mission extensions will begin Oct. 1, 2006. The spacecraft beginning extended missions have already completed a successful prime mission plus years of additional service. The extensions occur when NASA's newest Mars spacecraft, named the Mars Reconnaissance Orbiter, is about to begin its main science phase.

It would have been quite a joke if the mission had suddenly ended on October 1... you know... 12 meters from the edge of Victoria crater!
I would have loved to see the faces of the folks over at UMSF.
