The point I'm making is that the London Olympic's is a wonderful event, BUT, the cost of the Mars lander is only 1/5th of that cost.
BUT the Mar's lander is considered a waste of money and NASA have been shut down and there are no other mission's planned.
The Olympic's have given us, humanity, what precisely ?
The Space Program pushes the bounds of human achievement and knowledge, it's also given us velco, WD40, etc etc etc.
What is the best use of resources ?
Is that clear enough ?
