[meteorite-list] Why Mars Is a Planetary Runt

[Kelly Beatty]

Paul...

thanks for that posting and the links. Walsh et al's scenario is both
tantalizing and provocative - it's amazing to think how the solar system's
architecture might have been shaped top to bottom by big-bully Jupiter. (FWIW,
I wrote all this up for S&T last October: http://is.gd/CDdez4)

but it's not the only explanation being kicked around by planetary scientists
for a runty Red Planet: http://is.gd/qbtGAI


clear skies,
Kelly
