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

Do you have a reference to who first suggested it? The following is a study reported in 1989 which references previous studies. Science News Mar 25, 1989 "According to S.A. Phinney... kicking a rock hard enough to free it from Earth's gravity would require a meteorite capable of making a crater more than 60 miles across. In addition, Mars' orbit is much larger than Earth's, so the chance of an Earth rock hitting Mars is about 10 percent that of the same thing in reverse.... ...The group found fewer particles seemed likely to get to Mars than suggested by some previous analyses." |

Looks like an iron meteorite. But a very intimidating one with a strange hole in one side. I hope it doesn't bite!
