A misty morning on terraformed Mars. After centur- ies of atmosphere control, chemical additions to the soil, & the release of water ice deep below the surface, Mars has been made habitable. People can live & work on the once harsh & frozen insred planetins without oxygen equipment, space suits, & special living quarters. Solar panels & wind- generated electricity power the new world. A cargo glider passes overhead. The towering desert mesas of old have become the coastal cliffs of new continents & islands. The process of terraforming humans - is technically feasible but would be enormously expensive & take many centuries.
