The circled crater looks young. Perhaps it will be the next stop.

Yeah, I think you are right.
Speaking of craters, I saw that today's imaging plan has a sequence to take a pancam shot of a crater named "Gjoa". I believe it is this tiny little crater right beside the rover's position on sol 2014.
After searching for its meaning I found this: http://en.wikipedia.org/wiki/Gjøa. "Gjøa was the first vessel to transit the Northwest Passage. With a crew of six, Roald Amundsen traversed the passage in a three year journey, finishing in 1906." Really nice name selection, isn't it? |

QUOTE (alan @ Sep 24 2009, 06:58 AM)  The circled crater looks young. Perhaps it will be the next stop. Block Island was visible in a HIRise photo. Large slabs of bedrock are often visible on HIRise photos. However, the only distinct rock that I remember seeing on the open plains was Block Island. What I wondered is whether all distinct visible rocks on the open plains in HIRise photos are meteorites? I wonder whether it would be worth searching for similar distinct rocks on HIRise photos over Oppy's entire projected route to Endeavour Crater? If we found such a rock then we could suggest a deviations of a few 100m to the left or the right to investigate that promising looking rock. |

 I see 3 dimples in this shot. I am guessing those are tiny craters. I would like to the them look at one with the Microscopic Imager. Source -------------------- |

Bang my head moment here, but in my view from Google Mars the HIRISE image ends before this point Alan. Did you do your own overlay? OR am I doing something wrong here? -------------------- If Occam had heard my theory, things would be very different now.

James, thanks for finding the post but the link above points to two pages before, at least on my browser. This one goes directly to it: http://www.unmannedspaceflight.com/index.p...st&p=142132
(BTW, I should better add the link to my previous post on this thread.) |

I wonder whether it would be worth searching for similar distinct rocks on HIRise photos over Oppy's entire projected route to Endeavour Crater? It might be worth equipping future rovers with an instrument for accurately dating meteorites from their isotope ratios. If meteorites are common on the Martian surface, that might serve to constrain the age of the terrain and the rate of erosion. Perhaps an enhanced version of the APXS could have that capability. |

Thanks James. I knew it had to be something like that.

Looks to be about 4m across.

It's partially visible on this image: http://qt.exploratorium.edu/mars/opportuni...U9P1861L0M1.JPG
Now, it's 70m behind the current position.

We're almost 500m west of Block Island already.

Indeed, at this pace, we could be at Endeavour in a year and a half (or so, I'm not claiming precise arithmetic here). Wishful thinking, perhaps, but I am loving the current commitment to drive, drive, drive. Keeping my fingers crossed that they have truly figured out the key to keeping the RF wheel happy without delaying rest stops.

It'll become even better for RF in a few more meters when we'll hit the hard ground
