Good eye. To me it looks like a low rock in front of the taller rock. Instead of the ground under a protrusion, the bright sliver is the top of the low rock. And instead of the shadow of a protrusion, it's the front edge of the low rock, out of the sun.
But stereo should help settle it... |

QUOTE NASA's Opportunity Mars rover, which landed on the Red Planet in 2004, now holds the off-Earth roving distance record after accruing 25 miles (40 kilometers) of driving. The previous record was held by the Soviet Union's Lunokhod 2 rover.

The Release on the 40 km (25 mile) mark for Oppy has a new graphic (showing Oppy on top) with the distance of a marathon noted ...
AND ... A new name. From the large scale map (http://www.jpl.nasa.gov/spaceimages/details.php?id=pia18404) in appears that the valley of the smectites has been named: Marathon Valley |

Here's the wonderful graphic showing Oppy's distance record against the rest:

I am sooooooooo surprised by this anouncement.
Lunokhod 2 distance is still "uncertain" and we all know here that the record is around 42 km and NOT 40. We've been told that they'll made such anouncement once they'll be absolutely sure that Oppy's will have roved longer than Lunokhod 2. So far we're absolutely sure this is not the case. Go Oppy, go, 2 more to g Edited. The one record that Oppy already hold is there: http://www.unmannedspaceflight.com/index.p...st&p=211003 -------------------- |

I've been told that the Lunokod 2 odometry has been re-computed from LRO imagery to be 39.1 Km.

A nice basemap for Opportunity's travels is available. Also there are no firm plans post Marathon Valley.

According to JPL's press release:
QUOTE Irina Karachevtseva at Moscow State University of Geodesy and Cartography's Extraterrestrial Laboratory in Russia, Brad Jolliff of Washington University in St. Louis, Tim Parker of JPL, and others collaborated to verify the map-based methods for computing distances are comparable for Lunokhod-2 and Opportunity. Anyone know if this will be published? |

Reports of my deification have been much exaggerated, or at least are somewhat premature.
It looks as if the previous claim of 42 km has been dropped. I think everybody is agreeing with the new distance. I overlaid the tracks visible in LRO images on a soviet-era traverse map (that comparison might be on UMSF somewhere) and felt that the old distance of 37 km would need to be increased, but I was surprised when the 42 km distance was announced. 39 km looks more like it to me.
