    Great as the space shuttle was, it was not a great vehicle for science research, save for the effects of weightlessness in space. I loved Apollo and I have many of the missions complete on DVDs but the future of space exploration is robotics. It's cheaper (by orders of magnitude), it doesn't endanger lives, it can do real science and it pushes to robotic envelope. The current Rovers on Mars Spirit (now defunct) and Opportunity (still chugging along) cost 1 billion dollars, about the cost of one shuttle mission. A human mission to Mars could cost a trillion dollars.
