The dune tops look very soft to me, best to take care

QUOTE (abalone @ Jul 14 2006, 12:56 AM)  The dune tops look very soft to me, best to take care I noticed that the NASA updates have been very sluggish lately on Opportunity. Perhaps, it is as simple as someone being on vacation or maybe there is some uncertainty on how to best approach the big crater. Anyways, what are people's thoughts on Beagle crater, being more specific, do people think Opportunity will enter this crater? I would be very interested to read what the people on this board think. BTW, are there any other Red Sox fans here? |

Tesheiner's method is the fundamental method for locating planetary landers, and has been ever since Ewen Whitaker did it first for Surveyor 1 (and strictly speaking, by Jaffe et al. just before him, but they got a bad result). But it does depend on being able to match features between the pan and the overhead view. A lack of such matches is the reason Luna 9 couldn't be located in the same way.

Route map, updated to sol 878.
PS: This is my last update to the map 'till mid August; I'm starting my summer vacations. |

Thanks for all the map updates, Tesheiner! They've been an integral part of the long journey south for many of us. I hope by the time you resume, we'll be at Victoria! |

I go here several times everyday to look for new maps, you're doing a fantastic work!

Not that I'm in pessimistic mood but I think Tesheiner will be back before Oppy is on the rim of Victoria Crater... -------------------- The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.

this is going to be a hard time without our daily fix of your Route-Map updates
 In the mean time, I for myself can't even think about the progress of the MER mission other than in the daily rythm of your fine map updates ... actually it's the first internet address I click on every morning too look for a new Tesheiner Route Map update [/quote] I hope by the time you resume, we'll be at Victoria! [quote] don't worry: you won't miss the Victoria approach ... by mid August, we will probably still be in the middle of the Beagle-Crater-Campaign

Don't worry, there are plenty of people to carry on the route map work - I've covered for Tesh in the past but there are many others as well.
I'll be able to do it for a couple of weeks but then I'll also be off till mid August! (Really hoping not to miss Victoria arrival, note to rover drivers - not before August 16th, ok?) James -------------------- |

Thanks Tesheiner for your dedication. Have a good vacation away from the Mars front.
James, thanks for picking up the cudgel and leading the charge. I will try to keep your back safe by continuing to hack my own route map and yelping when I think there is a difference more than a few meters. I usually proceed by determining the direction of motion by comparing before / after panoramas. pancam / pancam comparisons are the best, but pancam / navcam can work too. I then determine the distance with a set of parallax computations of selected points in both before / after 3D pairs and then apply direction of motion cosine corrections. I usually can determine the direction to a few tenth's of a degree and the distance to a few meters -- unless of course Oppy is in featurless dunes -- where the major difficulty is finding suitable features to parallax measure. |

I guess you've all noted that Tesheiner went on vacation when we were in a place where we can see a lot of features so we'll not be lost! That's what I call dedication
