The Next Giant Leap For Mankind

NASA is serious, very serious, about launching the most difficult mission ever attempted by the human race - putting an astronaut on Mars. The voyage will cover hundreds of millions of miles and take two-and-a-half years roundtrip. It sounds like science fiction.

To make it scientific fact, the United States needs to first flex its deep space muscles again on familiar terrain - the moon.

It’s been nearly 40 years since Neil Armstrong took one giant leap for mankind and almost as long since the American public was truly captivated by the space program. You may not know it, but as 60 Minutes correspondent Bob Simon reports, the journey to send humans back to the moon and beyond has already begun.
