What are you talking about? The point is that Mars is far more like Earth than any other world in the solar system with all the resources needed to support an idnependent civilization. It is not as useless as the Moon for colonization as EP implies.
Mars certainly has a far harsher environment than many envisioned before Mariner 4, but the empression that mission gave that Mars was like the Moon was soundly revealed to be false.
