Another point of clarification: This article is not a WP:FORK of Life on Mars. The reason is that Life on Mars covers life through the entire history of Mars. Modern Mars habitability by focusing on present day habitats can cover it in more depth. Articles can overlap if they have significant amounts of own content, as is the case here.
