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

On a world with a probable history of a magma ocean and with well differentiated crust, mantle and core, one problem I've thought of won't be a problem.
Heavy metals. Would the heavy metal content of a chondritic soil or more specifically a carbonaceous chondrite soil cause problems? In California, there's serpentinite and related terrains formed of up-thrust mangled bits of upper mantle. Lots of plants DO NOT like to grow there. They have decidedly special biomes growing on them. CChondrite soils would be worse! |
