An interesting article to read. I think there is much more research needed into the weather conditions on Mars. However, I think that the question of life on Mars was settled in the ‘70s but not admitted. Earlier Mars Landings found the traces of gasses that could only have been made through biological processes. However, NASA would not openly admit life had been found. Now, we have sent enough life contaminated landers to make sure that life, from this planet, can be found.
