littlesparkvt writes in with news about the possibility of a privately funded Mars mission. "Millionaire Dennis Tito became the first paying customer to make a trip to the International Space Station and now he wants to launch a privately funded mission to Mars in 2018. Dennis paid a reported 20 Million to ride aboard a Russian rocket to the International Space Station and has since stayed out of the spotlight, until now. There’s no word whether the trip will include humans, there will be more information on that fact next week. Considering there is little time to train a crew for the mission the flight in 2018 will most likely be an unmanned probe. There’s also a possibility that the first mission to Mars from this private investor will harbor supplies for future astronauts. Plants and food are a possibility as they would take much less space than a full human crew."
