Time for a new thread.
After moving southwards for ages, the "detour" by the western path has started with a 60+ meters drive on sol 1942.
There are no images yet --they should be available on the next update-- so this image was calculated solely based on the rover's mobility info. I'll update the route map later. |

as far as cratering, I am sure the physicists and meteorite guys will weigh in , but we now have two pretty hefty meteorites (assuming that Block Island is one) that were found lying at the surface within 10 kilometers of each other and within the rover's vision... that is a significant observation.
as for the reasons.... angle of attack, speed, did it bounce or fragment? and the crater is covered over now...are any of the small craters in the near vicinity possibly related? Far away craters related? how long have they been sitting there? if you have 2 big meteorites every 10 sq miles, how many are lying on the surface of the planet? These few questions are from a multitude, that if answered well, will earn someone a PhD in Planetary Geology one fine day. -------------------- CLA CLL

QUOTE (PDP8E @ Jul 29 2009, 10:36 AM)  ....and the crater is covered over now... The crater no longer exists. If it did, the meteorite creating it would be buried beneath it. Remember that a significant amount of material has been worn away from the surface that Opportunity is roving over. The layer of "blueberries" lying on the surface were eroded out of a layer of rock that is long gone. The crater was in that rock, or some other long gone layer. |
