TruthSeeker, Maybe you should change your name to fantasyseeker. We are orders of magnitude away from He3 fusion and the only major source of fuel within reach is the moon. It isn't even the easiest steady fusion technology we hope to obtain (someday in the distant future). Geodesic, It was a funded program from 1957-65 and much ongoing research in the military has furthered aspects of it. The feasibility is beyond question and it utilises existing technology requiring only adaptive alterations. Phlog, Like I said, acceptable risk. None of that would matter greatly in Antarctica. Even catastrophic rocket failure wouldn't result in loss of life as the crew could be ferried up separately.
