Should NASA Go to Mars?

On the 40th anniversary of the moon landing a quick question?

Do you think we should try to attempt a manned mission to Mars? And if so do you think it will happen in our lifetime, next 20-40 years?

It would be massively expensive but I think it would be exciting as well. The sci-fi fan in my would love it.

I remember reading an article years ago about all the technology that came from the space program in general and the moon missions in particular. it was really mind boggling. i think that mars missions would provide similar new tech

thoughts?
a few years back it was proposed we could do it for 55 billion, and in less than 10 years. It was a great plan involving sending supplies off first striaght to Mars, sending men to build a launch pad on the moon, and then shipping a transport system to the moon. Good stuff when you watch NASA's tv channel...
