To answer Ustrax's querries from the other thread, I think we can now see more of the
The leftmost (Endeavour north rim) and middle (far rim) features look similar. But it looks like we can see more stuff on the right, which is Endeavour south rim and Iazu. The view we had a few sols ago (2133) of Iazu was still partly obscured by dunes, so it makes sense that we can see more now. I can't see Bopolu in the navcams, though it could be there and buried in the jpeg noise... |

Below the minimum, I would say.
Check the route from e.g. VC up to here and that would give you a better km/month figure. |

Time and again we've played the X metres in Y sols means Z progress game.
It never works Ever. |

The old saying "You can have it done fast, or you can have it done right" seems applicable here.

Feels like the road to Endurance again, which is cool

Stretchy horizon comparison - animation. Now you've done it...let me have it! let me have it!!! -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

OMG !! This is amazing Astro0 !! We really have the feeling of a progression now.

Cool animation. I starred the whole day long at it, and now I think I glaciers at the Endeavour rim ... ok I starred to much.
But I hope we will get soon a third picture to this animation. -------------------- Need more input ...

1 - Are the current power levels on Opportunity any cause for concern re reaching Endeavour? (I just have this nightmare of us running out of juice 5 metres from the rim!) Two things. First of all, just say to everyone that AJS Rayl monthly report on the rovers is already online. Second, an extract from the named report: QUOTE "Opportunity is also a little bit energy-limited for its mission", said Matijevic. “Its power levels dropped from a high of 336 watt-hours earlier this month to "about 290 watt-hours" as the weekend began. The team expects this rover’s power production to remain "in the 250 regimes” for most of the next couple of months," he added. "It will drive as far as it can on any given day, basically drive down the batteries and recharge them the next day, so you should see a pattern of where we drive every other day at best.”

I've been meaning to post this for a while now, and the recent chat has spurred me on.
I've had a go at predicting what Opportunity can possibly see, both now and further along the predicted route. I took the HRSC topo for the area, overlaid a CTX image, plonked down a marker for (roughly) where I thought Oppy was at the time (about a week ago now), and then let ArcMap figure out what's visible for something 1.8 m off the ground at that point. I then tried again for a different point along the predicted path. So here's the base map for the area. The green dot is my poor attempt at a location. This is what might be visible at the moment (green is visible, red, er, isn't) And this is what might be visible in the future (from the red dot) This method is very sensitive to both the underlying DEM and the exact location you view from. I can get very different results by moving the marker just a tiny distance. So take it with a pinch of salt, and then add a bucket or so extra for good measure. It'd obviously be loads better if I could stick a HiRISE DEM underneath, as this method worked pretty well for the Pathfinder DEM. I'm actually hoping that the view heading down the gentle slope will be a lot better than this predicts. Pete |

Pete - chuck that Pathfinder demo of Viewshed in here as well ( I never got around to using it) - it demonstrates the power of the technique.
What Pete has shown ( for those who haven't figured it out ) is that certainly for the next several KM - we're not going to have a sudden OMFG HOAV moment - it will be a gradual progression as we've seen with Astro0's recent flicking GIF. |
