The Blue2Orange initiative aims to generate ideas and designs relating to the development of supportive technologies for Mars colonization.
Necessary Undeveloped Martian Technologies:
Martian Artificial Magnetosphere-Generating Satellite
Without a magnetosphere, any attempts to terraform Mars’ atmosphere will be in vain, as solar rays will strip away the atmosphere.
Dust-Storm Resistant Shelter
See: Dust Storm Impacts on Human Mars Mission Equipment And Operations (PDF)
Energy Sources Unaffected by Months-Long Dust-Storms
One possible solution would be a radioisotope thermoelectric generator.
