INSANE: Details of Manned Mission to Mars!

Super self-sufficient astronauts who could repair all the spacecraft's equipment and even manufacture the parts, able to grow edible plants, large 400 tonne spacecraft, recycled water and air, and huge budget from US$20 to US$450 billion are all part of the details highlighted on BBC News' website (via Slashdot). The launch target is February 2031 and the astronauts are expected to stay on Mars' surface for as long as 16 months before returning home. A one way trip would take about 6 to 7 months!
