When do you think, a human will walk on Mars for the first time?
Hmmm, you mean when will we hear about it? I have a feeling it could have already happened unoffically. But I would think definitely within the next 50 years.
Might be even sooner than that–check this out.
Pretty cool, eh? 
we’ll place a small colony on mars called the UAC corporation that harvests the natural mars dust and turns it into usable materials like water and fuel…then some creepy guy will raise hell (quite litterally) and demons/zombies and creatures overun the base in seconds then a lucky marine survives and send a distress beacon to earth and they send ships but then your told what an idiot you are coz the demons will now use the ships to get to earth then something else happens that i dont know coz i havnt completed doom 3 yet…but im close
p.s woah i need a life…meh what ya gonna do really?..plays more doom 3
Well if I was american I would hope never, all those tax dollars to goto a desolate planet? Pfft!
We’ve as a species have messed Earth up enough, I don’t think I really want us “out there” screwing up more.
I think we could see it within the next 20 years.
Well I also think it will be soon like10-30 years but I think they must find someone who could spend all that time in space that it takes to travel to MArs.
Does anyone know how long time that would take?
Shift; I don’t know if I believe in that but it would be very cool if they are right 
well if i could get the enigine on my ship to work…
We actuallu did our Group 4 project, which is a compulsory task in the IB diploma programme, on a Mars settlement; our task was to figure out how to terraform Mars or otherwise make it inhabitable, in Physics, Chemistry and Biology. It was really interesting, though the task itself proved to be quite difficult. In the end, we concluded that fungi was a bad way of terraforming Mars. xD
That is very cool Shift! Sign me up, I want to go for the trip - I would love to visit Mars 
Why dont the Mars rovers go to the face on Mars, and see what it is? Are there any planes to do this?
It would be cool to go to Mars but we need to build a space station first that way we could plan things out using the space station and it would make things easier.
