Elon Musk Unveiling Mars Spacecraft Later This Year
 

How long do you think it'll take for us to ruin Mars once we begin settling there? Musk said space travel to Mars is part of a larger vision of one day establishing a city on the Red Planet – partly to ensure the survival of the human race but also "because it would be an incredible adventure, the greatest adventure ever. It would be exciting and inspiring. There need to be things that excite and inspire people."
