Mars in named after the Roman god of war.  I wonder if Mars will ever be able to support life.
I think we will, humans are very intuitive. How long will it take to colonise do you think?
There has never been any life form found to date, but scientists are still curious about the possibilities.
It would provide a lot of perspective on our place in the universe and likely inspire many people.
There have only been two missions to search for life, and they have both come back inconclusive.  I feel that we may be better equipped to research as time moves forward.
Oh really? Well hopefully if/when we get people on Mars, more conclusive evidence will be discovered to settle the debate. 
Approximately two thirds of spacecraft that has been destined for Mars has failed in route, so likely a very expensive journey to complete.
