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. |

... I understand that the most interesting meteorites of all would be fragments of the Earth close to 4 billion years old. Metamophism has severely altered all rocks of this age on Earth but it has been suggested that fresh fragments of Earth rocks of this age could be found on the Moon or Mars. What a far-out thought! Those possibilities had not occurred to me, though they should have. Thanks for mentioning that, Paul. Do you have a reference to who first suggested it? -------------------- ...Tom

Given that any ejecta from an Earth impact would be going the wrong way in the gravitational well, what would be the probability that it could have the kick off velocity necessary to reach the orbit of Mars? And since Mars sweeps a greater orbit than Earth, wouldn't this further diminish the possibility of impact? Given the resouces available on site, how could we identify the provenance in any case?
