Oh, I watch the Discovery channel. It's very intersting, one of my favourite TV channels.

From: http://news.discovery.com/space/miss…ks-110718.html

"The insistence that we need a faster propulsion system just allows politicians to postpone a Mars mission," said Zubrin, author of the recently re-released book "The Case for Mars." Zubrin proposes a three-stage, 18-month round-trip Mars expedition that will send a crew habitat ahead of time, as well as devices to produce fuel for the return trip.

Also http://www.uvm.edu/~wgibson/20f12/Sample_paper.pdf which list a total time of an expedition (including surface period) from 3 years to 1.5 years depending on fuel spent.

The 400-450 days is from Wikipedia, and it's also what I've heard repeatedly on my 40 years of following space exploration.
