We'll soon know what kinds of crops we can grow on Mars! Bonus, the fruits will be already freeze-dried!

I don't know much about heavy-metal content of chondrites. Do you have references?
Although the Mar's convective mantle engine appears to be inactive nowadays, it may have been more active earlier. And certainly Mars has been hot and is differentiated. --Bill -------------------- |

Full inline quote removed - Admin.
An Undifferentiated Chondrite would have much more heavy metal content. All those Siderophile and chalcophile elements are concentrated in the core of the Earth. Also, look at the fundamental differences of Earth and Mars. However you look at the situation, the bulk density is different, the chemical activity is different. Mars is made of different stuff then Earth is, and then it evolved different again. Never make the mistake of assuming that Mars is "like Earth"... -------------------- - Nick
