Musk's Mars rocket

In a much-anticipated talk at a space conference in Mexico on Tuesday, SpaceX founder Elon Musk revealed his grand ambition to build a city on Mars of as many as a million people and as soon as the 2060s. The plan centers on a huge new SpaceX rocket (shown here in a slide from Musk's presentation) even more powerful than the huge Saturn V rockets used for the Apollo missions of the 1960s and '70s.
