What is the name of that show?

Okay there is this show that features on the Science Channel (I'm pretty sure, it could possible be National Geographic Channel). The host is Australian or British and he talks about if man was to go or live on various planets in our Solar System, what technology is needed to survive. Its not the show Wonders of the Universe...and if this helps, the show creates almost like a comic book when showing the colonization of these planets. I know this probably sounds stupid but I cant remember what this show is and Ive tried going on the Science Channel and National Geographic Channel website and look at their show listings and it doesn't show all of what they feature.
