It is impossible to live there without special equipment, indeed. However, we believe that it is possible to establish a Marsian base in the nearest future. Humanity has built an International Space Station, which has been in operation for quite some time, that means that there is experience of creating habitats in Space. Combined with technologies that exist since the Apollo programm, it would be quite possible to establish an extraterrestrial colony. On the other hand, a very short visit might not be that possible, as there is only theoretical knowledge of launching a space ship from the Mars surface.
Suffice it to say, it is a topic for a very long discussion.

We are grateful for your opinion on the subject.

Thank you.
