40 days and counting. The long wait is almost over!
I wonder whether we will get enough data to test new simulation theories like this one. http://space.newscientist.com/article/mg19...solar-wind.html What do you expect from this first flyby? |

I'm sure ngunn is right about that - the bright crater is younger and its ejecta covers the crater chain.
This chain of craters is most probably a normal secondary crater chain rather than a disrupted object crater chain. And statistically, secondary chains are much more likely to occur. On the Moon we have thousands of secondary chains and maybe 2 or 3 possible disrupted object chains. Phil -------------------- ... because the Solar System ain't gonna map itself.

Looks like theres a collapsed area in the middle of the infilled crater in the center of the above image: -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
