Mars trip costs
"The roughly 440-day trip is expected to cost about $20 billion, with Russia suggesting it would contribute 30 percent."
" ''It must be an international project,'' said Vitaly Semyonov, head of the Mars project at the M.V. Keldysha Space Research Center. ''No one country could cope alone with this task.'' "
But according to Forbes there are at least 5 individuals who could afford the whole project on their own... surely an international consortium can manage it??
