At present no human has ever travelled to Mars and so, at present no human has ever landed on it.
The mineral sample that did not offer proof of life on Mars was likely from a non-biological source, such as a geological formation. The absence of evidence for life in the sample doesn't rule out the possibility of life on Mars existing elsewhere, as microbial life might be present in other locations on the planet. Further exploration and analysis are needed to conclusively determine the presence of life on Mars.
No animal has ever been on Mars.
No, no human being has ever stepped foot on mars.
Jarosite is the sulfate mineral found on the surface of Mars that indicates the past presence of liquid water.
The intention of most of the missions to Mars was to learn more about the mineral composition of the surface. Namely, if water exists or did exists, and whether lifeforms were ever present.

For ever!
There is no colony on Mars and no space shuttle will be traveling to Mars. There is a robotic probe on Mars. No human being has ever been there. At the present time (2013) it is impossible to say if any human being ever will go there. Certainly some people would liketo go there. But no trips are scheduled.
