Beat me to it, fredk! This is the start of a whole new adventure - and a new thread, methinks.

And according to http://nmnaturalhistory.org/space-science/rover-field-reports-mars, we are headed eastwards, ie straight downslope, after threading the gap.

This is the best map I could find, but ends just where we want to see where we are going. Can anyone link a better wide view map, or one with an elevation grid?

Thanks fredk, the official route map is great. However, I don't see any difference in the slope of the two valleys. So does anyone understand why we couldn't go down Marathon valley to the bottom and we can this new valley?

Posted by: marsophile Sep 8 2016, 02:32 AM

My take on this is that we could go down Marathon Valley, but then we could not come back up in order to go down this other valley, which is what we want to do for science reasons.

Would it be possible for someone to do a version of this map that shows the gulley that is the goal of this extended mission?

Posted by: Phil Stooke Sep 8 2016, 04:07 PM

My impression - without a direct link to the mission team - is that the rover will not go all the way to the bottom until it reaches the gulley area. Where we are now the valleys slope down until they reach areas with too much loose debris on them, making a climb back up very uncertain. So they can go up and down as targets present themselves, to a certain point but not beyond.

The location of the gully doesn't appear to be covered by http://mars.nasa.gov/mer/mission/tm-opportunity/images/MERB_Sol4430_1.jpg, but big THANKS to Sean who has made it easy and indeed delicious fun for us to explore certain areas in high resolution by sharing his Sketchfab projects.
Here's an excerpt from that showing (1) approx sol4488 and (2) that http://www.midnightplanets.com/web/MERB/image/04487/1N526526679EFFCSPCP1826R0M1.html and (3) the presumptive gulley, further detailed in Post #314 of the http://www.unmannedspaceflight.com/index.php?s=&showtopic=8058&view=findpost&p=232054 (IPBoard cross-thread linking doesn't seem to work)
I'd venture a guess Oppy will traverse at various elevations along the ridge distracted by ad-hoc targets as it makes its way south to http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=39875 gully.

Posted by: Phil Stooke Sep 11 2016, 01:52 PM

Wharton Ridge... do we know where the name comes from? I'm thinking it may commemorate Robert A. Wharton of the Desert Research Institute in Reno, Nevada, who died on 19 September 2012. He conducted research on Antarctic ice-covered lakes with similarities to possible environments on early Mars.

http://www.midnightplanets.com/web/MERB/image/04505/1N528123176EFFCT60P1673R0M1.html in lower right suggest consistent upslope winds here, wondering if that is generally true on both sides of the rim, as i was under the impression that the wind pattern over the crater is west>east on a high level which id assumed would also tend to effect that at ground level as well, but i guess not being a meteorologist i was surprised by this, so am just guessing its still on the mains a general west>east flow but the air is instead getting pulled up the rim under a vortex effect imparted by the intervening crater rim to that flow, or perhaps its just rising up due to ground heating and following the contours up the rim..?

on another note that http://www.midnightplanets.com/web/MERB/image/04506/1P528210174EFFCT60P2355L2M1.html just behind the boulder on sol4506 turns out to be part of the ridge, not a background feature (parellel view)


Posted by: Phil Stooke Sep 28 2016, 12:38 AM

Given the complexity of the topography here, it's not really possible to guess a local prevailing wind direction from a regional upper-level wind direction. In the floor of Endeavour below us, the large field of light-toned drifts suggest north-south winds, approximately.

Here is an update on the Oppy arena...



https://skfb.ly/TXqM

Posted by: fredk Oct 5 2016, 04:00 PM

A sketch of future plans from the latest http://www.planetary.org/explore/space-topics/space-missions/mer-updates/2016/09-mer-update-opportunity-exits-marathon-valley.html

QUOTE
Once her work at Gasconade is done, Opportunity will rove on, driving southwest through the rim and then angling to motor up a Cape Tribulation slope to targets at the top of the hill.

QUOTE
The longer-term objective is to head south across the plains or along the apron on the western side Endeavour’s west rim and over to Cape Byron where there’s a gully believed to have been carved by water or a liquid debris flow.

QUOTE
"...we will exit the gully much farther into the crater than we are now at Spirit Mound,” said Arvidson. “There are a set of benches we'll drive across and one of them could be an outcrop of Matijevic Formation."

Posted by: atomoid Oct 5 2016, 08:22 PM

Still trying to get a handle on where exactly we are going... perhaps the area rectangled (with adjacent processed inset) in the google earth extract below may be the assumed gulley that fredk pointed out early on, if it's enough on the Byron side, and it does seem to be the only feature that fits the description to my untrained eye, if that all pans out the arrows may identify the bench of the presumed Matijevic Formation.


Posted by: Phil Stooke Oct 5 2016, 09:09 PM

Yes, I think that is the gully.

Phil

Posted by: Jaro_in_Montreal Oct 7 2016, 09:26 PM

Interesting.
How come Oppy gets to go near potential sources of moisture, but Curiosity must be rerouted to avoid them?

Posted by: fredk Oct 7 2016, 09:52 PM

The features near MSL bear some resemblence to recurring slope lineae (RSL), dark streaks that appear and reappear and that might be related to current water.

If the gully near Oppy was carved by water, it was probably in the very distant past - I haven't heard anyone suggest water was still present. The Oppy gully isn't an RSL.

Posted by: atomoid Oct 7 2016, 11:00 PM

It's almost as if the gulley near Oppy had to have been exhumed, it just looks too surficial to be that ancient, perhaps what we see is just a lingering remnant of its once lower reaches, though I have no idea if we know how deep these slopes have been eroded over the eons.

TBH my bet would be that it's more recent, and due to dust or debris flow with little or no water involved - perhaps a little lubrication to help things move if it dates from a high obliquity period, but my gut feeling is that the idea of liquid water being involved is more wh\t people are determined toi find than what is actually there.
Would be delighted to be wrong though!

Good luck on the Imaging attempt, and good luck to the Schiaparelli team! smile.gif

Posted by: Explorer1 Oct 14 2016, 07:03 AM

Since Oppy is on the inner west rim of the crater though, the best view would be if the trajectory overshot the centre of the landing ellipse and ended up far to the east; if the targeting is perfect than ironically the slope will block the view (see http://www.leonarddavid.com/europe-readies-mars-lander-for-october-touchdown/) . And obviously the MER team has its own mission which doesn't involve doubling back to the other side of the valley for the sake of one 1 pixel. Don't expect anything like the cover of the Martian Chronicles..

Posted by: PaulM Oct 18 2016, 11:27 AM

Am I right in thinking that the landing ellipse for Insight at Meridiani Planum is roughly the same as that for Schiaparelli? Oppy may therefore be able to take a photo of Insight landing in 2 Year's time.

Posted by: Phil Stooke Oct 18 2016, 11:51 AM

No, not at all. Insight is heading for an area north of Gale crater, half a world away from Meridiani Planum, and too far north for Curiosity to see it.

Phil

Posted by: fredk Oct 19 2016, 09:59 PM

Here's the difference of each 4528 pancam frame from their mean, then stretched and smoothed:


I see no sign of Schiaparelli, just a few cosmic ray hits. (This is daytime at Meridiani so the exposures must be very short and so I wouldn't expect the lander/chute to be streaked.)

Lots of rocks beyond Pompy's tower, in combination with the slope I suspect they will need to watch the tilt closely as Oppy drives across that.

More images just came down for this mosaic of the ground around Pompys Tower and our wheel tracks that we left during the last drive. I likely won't get to those today. Will most likely release a final version shortly after we leave this area just incase more are taken before hand.

Posted by: James Sorenson Nov 25 2016, 10:57 PM

I am really impressed with Oppy's Sol-4564 down-link. 80 images down, I haven't seen that many down in a single sol for quite awhile, Since Sol-4006...A sign that Oppy is testing in flash? Or just a great down-link while still in RAM mode? time will tell.

Posted by: Phil Stooke Nov 26 2016, 09:39 PM



This is Robert's panorama with a bit of extra processing - and I added a half frame at the end which he had omitted. I forgot to match the two ends properly so it doesn't join properly in the circular view. Still, it gives an idea of the surroundings and the tracks skirting Pompy's Tower. What would little Pompy have thought of this?

Looking at Phil's http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=40515, it seems we can see over the first ridge now, so im trying to get a handle on the path ahead so unless I'm mistaken it looks like we cannot yet see the http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=40232 in the http://www.midnightplanets.com/web/MERB/image/04582/1N534958045EFFCT1DP1984R0M1.html as i suspect its still out of view behind the second ridge to the right in the direction of the arrow in the below crosseye.

Interesting, as I had interpreted that as the deliberate creation of a trench to provide something to study over the holiday period. But maybe it was an accident as you say. And maybe a spot of serendipity.

http://www.marsdaily.com/reports/New_Year_yields_interesting_bright_soil_for_Opportunity_rover_999.html

QUOTE
Just before the holidays, the rover encountered some difficult, steep terrain. As the rover tried to advance up 20-degree slopes, the wheels began to dig up the soil and progress slowed to a near stop.

Sensing this, the rover stopped her drive and waited.

So, on Sol 4590 (Dec. 22, 2016), the team had Opportunity back down a short, 2-foot (70-cm) distance to put the rover on a more solid footing.

Before we could continue with rover activities through the holidays, Mars Odyssey went into "safe mode," an event that prevented relay data return from Opportunity. The rover was patient for several sols and in good health.

With Odyssey back, on Sol 4601 (January 2, 2017) Opportunity moved another 6.6 feet (2 meters) to get a good look of the terrain that was disturbed during the up-hill driving challenge.

The disturbed soil reveals brightly colored, unconsolidated material that is of great interest to the science team. So, the plan ahead is to use the rover's robotic arm instruments to investigate this bright soil.

We had some images of what is probably Phobos on the evening of sol 4612. Here I've tried to isolate the stars, by registering and averaging the two differences of two similarly exposed frames (with stretches and Gaussian smoothing):


The stars are the short streaks aligned roughly from 2 o'clock to 8 o'clock. (You can see some residual scarring from imperfect subtraction of Phobos.)

Edit: I realized I could get a cleaner subtraction of Phobos by smoothing before subtraction; result replaced.

Posted by: Phil Stooke Jan 15 2017, 11:17 PM

It's Deimos (from tweets by Mike Seibert, and the file descriptions on Midnight Planets).

Phil

Posted by: fredk Jan 16 2017, 05:37 AM

Thanks, Phil. I'm out of practice with the moons - it should've been obvious. Phobos has marked "retrograde" motion, while Deimos is nearly synchronous, and this bright object is in nearly the same position in each frame (hence the good subtraction).

I think you're right, Phil. At first I thought it was just the increase in tau (we've shot up from around 0.8 where we've been for a while to 1.1 on 4653) but that does look like a gust - huge at that distance.

QUOTE
In one of the Navcam panoramas we can actually see [the storm] in the distance,” said Callas. “This is the first time we've actually seen one of these dust storms from the ground.

I'm surprized by this comment - usually all we see is an increase in tau and I would have guessed that a storm edge would be gradual. I guess he must be referring to the large 4653 gust we talked about. I don't know how easy it is to define the edge of a local storm - maybe it would have various gusts forming and disipating. But it certainly was true that this was one huge gust.

Also from Nelson:
QUOTE
the dust factor... dropp[ed] from around 0.92 on Sol 4654 to 0.84 on Sol 4655 (February 26, 1017).
Needless to say 0.92 is pretty much pristine. Of course now as dust settles that will rise.

I hope so to, but I find doing a full 360 color panorama is pretty slim to none given Oppy's flash situation and would take roughly a month to do in current RAM mode. That's a whole month of sitting still when she could be driving and a month closer to the gully. I do hope a smaller color pan is taken somewhere along the way, like at the point you suggested. smile.gif

Posted by: marswiggle Mar 10 2017, 03:43 AM

I'm happy with fredk's yellow line, but beyond that, it seems we must use a bit grander scale to get features matched. From this several years old anaglyph (the respective view in reduced size), it looks like the peculiar ledge on the opposite Cape (is it called Cape Byron?) is akin to the white-headed feature in pancams. It is obvious that we should expect to see that Cape before being able to peek into the rather deep valley in between. The fresh dark crater is aligned with our destination gully along the lowest topography of the valley (thus being hidden by the local rim). Also the gully itself would appear rather subdued in relief until we practically drive on top of it. -Just my two cents as they say.

 

Posted by: fredk Mar 10 2017, 04:50 AM

Yeah, the feature I'd circled green would appear far larger than that.

Here are my corrected identifications:




As we proceed we should see the redlined ridge extend towards the lower left, until the head of Perseverence Valley (white arrows) will appear as a dip.

Well, from the new http://mars.nasa.gov/multimedia/images/2017/active-lifting-during-martian-dust-storm I guess they were talking about the 4653 pancam sequence, not the navcam frame. The pancam sequence spans a couple of minutes, about 10 minutes before the massive gust was caught on navcam. Here's an animation:

You can pretty clearly see a huge (based on its distance) gust front moving in from the left (north), just below the horizon.

I guess it's possible this continued to approach and became the gust visible in navcam.

It's possible the batteries could last 15,000 sols before really degrading.

Who knew it could go full circle. Even when I started working at JPL 7 years ago, the idea of working in surface ops didn't even enter my mind. It was only last summer when people like Paolo suggested it that it became a possibility. Certified as an ECAM Uplink Lead on MSL just before Christmas, and Wednesday was my first training shift on MER for the same role ( plus MI duty! ) . It'll be a month or two before I'm certified on MER as well - but I can't wait to start contributing meaningfully to a mission that in every possible way - absolutely changed my life.

Here is Jan's most recent panorama in circular form, showing how we crossed the outcrop area.

Regarding that bright flat-topped hill... most places like that turn out to be just patches of bright dust. There was a small one immediately south of the exit point a couple of weeks back. They look intriguing but they are not really very significant. If it's a major mineral feature CRISM would probably have resolved it and we would know about it. It's not on the projected path so the science team don't regard it as significant.

Opportunity and Spirit's solar panel wing shape has always reminded me of the wings of a B-2 Stealth bomber. I wouldn't try base jumping to try it out though....I heard somewhere awhile back that because of it's stereo vision based autonomy, You can send a command to tell it to drive off a cliff and Oppy will detect the cliff and stop or ignore the command all together. It will try and find away around it and if it can't, will stop and wait for further instructions. If autonav was disabled though, could be possible I suppose? Paolo or Doug?

Of coarse I'm not suggesting anything...

Posted by: djellison Mar 28 2017, 02:32 AM

Yup - you can set tilt limits (that would get triggered early off a cliff) - every drive gets those. If AutoNav is on, it would see something like that as a hazard and stop - depending on what parameters you gave it.

I think this was simply a blind drive to the edge of the previous NavCam mesh though. That's what usually gets you the most bang per buck (meters per Whr)

I don't think you would be able to pick up Oppy from the wings, they are pretty flimsy. You can pick it up from the portion of the deck that is on top of the WEB. In fact the SSTB1, the testbed at JPL has loops there for a crane to pick it up in sase we need to lift it.

The vehicle has an IMU (Inertial Measurement Unit) a 3-axis accelerometer and gyro that report the vehicle attitude 8 times a second. We ALWAYS set max tilt limits, sometimes we set pitch or roll limits, but a bit more often Northerly Tilt limits (tilt towards the North or South). Both MER and MSL have the same IMU, a Litton LN200. MER's are slightly better than MSLs but either vehicle need to periodically reset the IMU to cancel out gyro drift. MER calls it GFA/QFA (Get Fine Attitude, Quick Fine Attitude) MSL calls it Sun Find but the procedure is quite similar: using the Sun position at a given time and the accels output to measure the nadir vector the procedure resets the North/East/Down coordinate system.

We also set Suspension limits. The vehicle monitors the position of the rocker/bogie to see if the terrain does not match what we expect.

Posted by: James Sorenson Apr 5 2017, 10:09 PM

It is likely just a mound of bright oxide dust, maybe with some of the flat sulfate rock that we see all over as well. At this point, it doesn't look all that interesting. Some pancam super-res imaging of it occurred on Sol-4691 for a better look at it.

Very nice, James!

the RAT has been used here for the first time in a long time. I think I'm right in saying that the RAT brush was last used on sol 4412 and the RAT grinder on sol 4370. There's not much life left in the grinding head, so it's used very sparingly. This must have seemed like a very significant target.

Not really. When going straight uphill the worst that is going to happen is that you can't, you just roll back and try a different route. When going downhill it is possible you can't control the vehicle's path. If the path the vehicle is taking is leading to an obstacle, you are toast (# Wopmay?).

That is going to be the biggest challenge when driving down Perseverance Valley. Fortunately I don't have much hair to lose anymore.

Looks as if they're beelining it to Perseverance Valley. I'm guessing that the science value of looking at a channel up close for the first time outweighs whatever the new crater excavated. Probably a good idea to get in a good chunk of the observation campaign in before winter, just in case.

Its brightness is very noticeable.

Posted by: Phil Stooke May 5 2017, 02:28 PM

"I can't recall seeing a feature like this on that scale"

Look back 1000 sols to the images on this page:

http://www.midnightplanets.com/web/MERB/sol/03749.html


(Wdowiak Ridge, sol 3749)

The geologists who run the mission have not noted this as anything especially unusual. I personally think it's just the same as lots of other lumps and bumps seen along the crater rim. There are much more compelling reasons to go down into the crater again, where broad areas of outcrop downhill from the 'gully' will be explored later.

Posted by: Phil Stooke May 5 2017, 03:32 PM

This is Jan's half-panorama from sol 4720 in a circular projection. It makes the slopes look much steeper than they really are. I would anticipate a drive out onto that spur just to the north of us (top of the image) to get a better look across the slope and into the valley.

Think we really need to visit that slab. it could be exposed Carbon ice.Gypsum..or whatever...
Its brightness is very noticeable.

It was intriguing enough for the scientists to consider dispatching Opportunity for a quick visit. It would be their only chance since once the rover descends into Perseverance Valley, she won’t be coming back this way again. “Our estimate was that it would take a month to go to Winnemucca, look at it, kick around, and get back,” said Golombek.

Ultimately, the decision was – no go

And ice would be much brighter than this - remember that Mars soil is usually very dark. Check out some of those old Phoenix ice pics.

It's unlikely to be ice now, but there may have been ice there sometime in the past. Note the potential remnant of a melt area to the west of the feature.

My very first post.

I am wondering. Why there is no talk of going upstream, west, of Perseverance Valley, for a bit.


If I were there, I'd check out that wash - upper stream bed source first very carefully, before committing myself to going over a thousand foot edge.

From what I can tell by the most basic Google Mars, the upper stream bed starts at a very small crater no more than a couple 100m west of the edge.

Add that new crater towards SW, and those bright white ring craters further on. A football field away or two all of them.
.

It just seems like there is not going to be an inspection of the headwaters, before going over the falls.



Been here every day, since 2009. Just now speaking up. This is the best website ever!

Opportunity has accumulated a decades worth of wavelength / albedo correlations encompassing sedimentary deposits, dust and Endeavour's Noachian deposits. I suspect that they have a pretty good idea as to the composition of the Winnemucca bright area. Given the environment we can be certain that it is not CO2 or water ice.

The TPS report also says this:

QUOTE
Nicknamed Winnemucca, the MER scientists considered sending the rover to check it out. But Perseverance Valley is the objective and winter is coming. Instead, the scientists are examining Winnemucca with ground imagery, remote sensing, and an orbital mineralogical detector.


So we can at least hope for some additional remote data on this interesting feature.

More Phobos transits on 4720 and 4721. These are easier to see in the public jpegs because there's a dimmer internal reflection of the sun that isn't clipped:

Hi David - the little valley is thought to be very old, certainly if it was formed by water. So the real headwaters, if there were any on the surface, would have been buried by the 'Burns Formation' sandstones (as we saw in Victoria crater and all through those plains), and if not then certainly buried under the modern sand dunes (tsk - I mean ripples) which we see all over the plains west of the current position. And there might not have been headwaters as such anyway, the water could have flowed out of an aquifer where the crater wall cut through it, or it could have been fed by melting snow. So, probably nothing to see. Anyway, it seems they are eager to get into the valley after doing some stereo mapping.

These images are from my first solo shift as ECam Uplink lead on Opportunity. Sequences p1961, p1962 and p1963 were lovingly hand crafted.....I even dropped the center 3 frames a few degrees from the usual drive direction 5x1 pointing to get a little more valley in there.

I can't even begin to put into words how it feels to go from founding this place 13 years ago, to working at JPL 7 years ago, to starting ECAM on MSL last year, and now on Opportunity this weeks.

It's one hell of a journey, in many many ways

The channel being ancient as it is would have accumulated a lot of dust and therefore I presume that the rover is going to have a difficult time to reach any minerals which would have been deposited by the water which formed the channel.

Posted by: RoverDriver May 16 2017, 08:40 PM

Hmm, I wonder if they are going to ask to drag our feet while down the ramp? Sort of a Spirit driving technique?

Posted by: atomoid May 16 2017, 10:16 PM

dragging the wheel sounds like a great idea, subsurface deposits hiding just under our feet..
Below is an attempted match-up (i may be way off) of features from http://www.unmannedspaceflight.com/index.php?showtopic=681&view=findpost&p=235792 and http://www.unmannedspaceflight.com/index.php?showtopic=8237&view=findpost&p=235798 those great works I recycled here rather than afflict the mess i stitched. The inset crosseye details a signifficant trough in the gully (green line)..
It would be interesting to have an idea as to how much original material has been eroded from the rim, as my recurring (and absolutely amateur) impression of the gully is it is more of a remnant of some fairly recent and short-lived Milankovitch cycle snowpack (catastrophic melt?) type of feature rather than a Hesperian era surface or hydrothermal emplaced creek.


Posted by: serpens May 16 2017, 11:54 PM

An eposter that provides an easy read summary of Endeavour including assessed erosion levels is here: https://www.hou.usra.edu/meetings/lpsc2015/eposter/2017.pdf

The spherule lag deposits on the plains imply that there has been only a few metres of erosion of the fragile sedimentary deposits since the Meridiani water table dropped around 3.5My, so preservation of remnants of an early gully seems quite reasonable following desiccation of the environment. Prior to that with a near surface water table at Victoria crater and the permeable sedimentary deposits there must have been a plentiful water supply at Endeavour.

Beautiful work Sean and much appreciated.

If the valley is as it seems a remnant water feature then the erosion resistant ridge below where it terminates (covered by regolith?) and the exposed polyhydrated sulphates rich area below that could hold a few surprises.
