Minerals

Minerals are natural resources needed as raw material for setup and extension of settlements on Mars. From recent unmanned missions some valuable minerals have been found, most of them by the Mössbauer spectrometer MIMOS II.

Goethite

Chemical formula: α-FeO(OH)

This mineral has been identified near the landing zones of the rovers Spirit and Opportunity, for example at "Columbia Hills". This mineral was probably created from iron under the influence of liquid water.

Hematite

Chemical formula: α-Fe₂O₃

This mineral has been found at the landing zone of Opportunity.

Olivine

Chemical formula: (Mg,Fe)₂SiO₄

This mineral has been found in Gusev Crater.

Better late then never. The problem to me is that this revsree will then be put in the hands of bankers who caused the crisis in the first place. How else will the revsree grow from interest if banks can't us it?Taxation? But people are already over taxed.After the great depression checks and balances were imposed on banks etc to ensure that the depression never happened again. The bankers lobbied over the years to be allowed to break the rules and for the checks and balances to be eroded until they were meaningless. It happened then it will happen Again.References :

Open Issues

• How exactly can iron, magnesium, etc. be extracted out of these minerals? What we need here are simple processes, allowing the exploitation with limited chemical and energy resources on Mars. The processing should be strictly lo-tech.
