We'll see. It's roughly located SE of that position and the last move, during sol 2279, was more or less in that same direction.
BTW, I *think* this pancam sequence was automatically triggered by the new AEGIS software.

Regarding the change of direction I note that prior to the move we had just rejoined the proposed route line and the latest move tracks that line very closely. I wonder how closely we will be following it from here onward?

Don't put too much store in the 'proposed route', it only denotes the general direction. The actual route will have to zigzag between small obstacles like larger than average drifts and (later) Anatolia-style troughs, with occasional sidesteps to look at items of interest.

The images taken during sol 2279 are already available on the JPL site.
Curiously, the navcams (
http://marsrovers.jpl.nasa.gov/gallery/all...nity_n2279.html) are tilted *up* 19 deg. instead of the usual 17 deg. down. It reminds me of that drive which was planned for X meters in one direction but was actually commanded on the opposite way.

Those navcams are odd. I wondered about cloud imaging - on the same sol there was a cloud in the fhazcam:
http://marsrovers.jpl.nasa.gov/gallery/all...FAP1205R0M1.JPGBut cloud navcams are usually a series of downsampled frames.
Maybe they're looking at sky transparency - those navcams show nicely how much the sky darkens as you move up from the horizon. To eliminate the effects of vignetting, which is symmetric about the frame centre, compare the brightness of sky the same distance from the top and bottom of the frame.
Edit - of course these jpegs are auto stretched, so they don't reflect how much the sky really darkens with height.

I've been gazing at Ant's
desktop image from a couple of days ago on my second monitor. It looks so clear and those hills so tantalizing that if I were standing there in person I'd swear the hills were only two or three miles away (instead of the 20 mile distance that the far rim is sitting at.) You almost want to break into a run.

Didn't we have a discussion in "Distant Vistas" about being able to see hills clearly from long distances (20-90 miles), even here on Earth? I'm thinking mid-March of this year.

Love it (reminds me of the crystal markers up Husband Hill story)
BUT....
I don't think the rovers will get buried. There are lots of rover-sized-and-smaller things around not buried, and we've seen the rovers themselves get dirtier and cleaner over time. I think they'll get some dust around the wheels for sure - but they'll be stood there looking pretty much as Spirit does right now in many many hundreds of years.

I notice that they are also doing frequent soil Pancams and the ripple-sand looks interesting at the bottom of the sequence now that the sand is thinning out.

Some highlights from that update:
QUOTE
“Driving backwards is really difficult with AutoNav, because... when you point the NavCams backwards, you have that antenna in the field of view and that makes it difficult to get a really good terrain map. But we have a trick in the works that will allow us to do AutoNav driving backwards using the NavCams.”
QUOTE
Interestingly, Opportunity seems to have encountered a different kind of ripple this month, smaller, wider, gnarlier ripples. Bellutta explained: “Typically the slopes on these ripples [Opportunity has been crossing] are about 12-15 degrees, and now they are more on the 8-10 degrees. On the HiRISE images, these ripples appear large and brighter.
QUOTE
The place where Opportunity is to make "landfall" has just been named Cape York.

"Cape York" I can dig it. Not the Garden of Eden, like Cape Trib, but appropriately dramatic.
The northernmost point of the Australian continent.
I once scrambled down the wet rocks to sit on the last one and dangle my feet in the Torres Strait.

70 meters in a cloud of dust every day
For those of you who don't follow American football, this quote is most likely a pun on the famous saying "Three yards and a cloud of dust". It refers to a style of offense where the ball carrier basically plows into the defensive line to pick up two or three yards be sheer strength and force of will. Nothing flashy. It's a style that's loved by football purists, but often derided as "boring" by those who prefer the more exciting but higher risk aerial game.
I think it's an apt comparison for our slow-and-steady rover who continues to chip away at her goal by sheer perseverance and dogged determination.

I have a math question to ask.
From our current position. How many 70 meter drives would it take for us to arrive
at Santa Maria Crater and The edge of Endeavour???
Thanks
It's not as simple as that Bobby. The route to Endeavour will be a stop-start marathon, not a set-distance-a-day sprint. Variations in local topography, power levels, etc, make it just about impossible to extrapolate. The answer to "When will we get there?" is the one beloved by kid-plagued parents everywhere...
"We'll get there when we get there"...
BrianL
Jul 4 2010, 08:17 PM
Agreed, but if Oppy were to maintain a straight line, first to Santa Maria (4.8 km away) and then Cape York (11 km away), and throwing in some capricious rounding, we're looking at at about 70 such drives to Santa Maria, and 160 drives to Cape York. Which means of course that the actual number of drives to those two locations will not be those numbers, and will almost certainly be more, given that they seem to have settled around 70 m as a safe, unstressful distance for the wonky wheel. That could also change as the drive progresses.

So, we're not there yet?
Seriouslyer, BrianL's figures do put the distance into some perspective. The recent super res pan pic makes Endeavour seem kinda close!
Deceptively close, yes...
But even more seriouslyer, BrianL's figures are informative. But anyone wanting to play the "Guess How Many More Drives" game should just go to Google Earth and measure the distance between Oppy and Cape York in metres. Then divide that by 70, and there you go, ballpark figure.
