I think there are a number of reasons to start a new thread. Squyres has confirmed we have turned east. We've passed the solstice and sunlight is now improving. Also we should be past the worst of the dunes now.
And, we've finally gotten new pics down! And for the first time I can recall, the jpl site has beaten exploratorium! Here are the lookbacks after the 2252 and 2254 drives: http://marsrovers.jpl.nasa.gov/gallery/all...KCP1795R0M1.JPG http://marsrovers.jpl.nasa.gov/gallery/all...NDP1777R0M1.JPG For those who don't know, the jpl site is one sol out of synch. You should add one sol to those numbers (2252 and 2254) to get the actual sols. There was a new drive on sol 2256: http://marsrovers.jpl.nasa.gov/gallery/all...Q8P1212R0M1.JPG |

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"... -------------------- |

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. -------------------- |

Oh, broody herr Stu, now everyone knows the secrets of my mathematical wizardy.

Bobby, calm down. It's a marathon, not a sprint. They'll drive when they're ready. Banging on the back of the car seat won't make them go any faster.

You in the US?
I haven't gotten a single business email today. I think we're constitutionally required to celebrate our independence from Stu for this entire week. |

Thanks STU. That makes me feel better.
Hey STU. If the Mars Rovers were a video game. Which one would it be? Playstation, X Box or Wiiii? |

...and so is 2295 Thanks for the updates ! BTW.: While the approximate limit of 70 meter per driving sol is well known (as explained, for example, in the latest MER report) I'd be interesting to know what is currently the limiting factor that determines if a given sol can be used for driving ? Is this drive-every-other-sol pattern that we see now still the same that we saw due to the "restricted sols" in the past or are there also other constraints (possibly related to wheel-current, energy-reloading etc.) ? If we were out of restricted sols, would it then be still be (theoretically) possible to use every non-weekend sol for driving ? |

Here's the most recent view of the horizon with a bit of a stretch. Some spots on the distant landscape behind the crater... should try to find them...
