Was Mars Terraformed

Authors: Greg Orme

This consists of a chapter from my book “Why We Must Go to Mars” and two unpublished papers. It examines the hypothesis that Mars was visited billions of years ago by aliens. They terraformed Mars by a series of oblique impacts aimed at the poles, these formed volcanoes on them including Tharsis, Olympus Mons, and Elysium Mons. The volcanoes outgassed thickening the atmosphere, they also sublimated the frozen atmosphere at the poles. The polar ice was also melted, this is traced in how it formed the Martian oceans. The rise of these volcanoes, particularly Tharsis, caused an imbalance of the planet inducing polar wander. The South Pole settled for a time a few hundred kilometres west of Hellas, the three main Martian faces (Cydonia Face, King Face, and Nefertiti) were on a great circle probably defining this former equator. Many possibly artificial formations follow this old equator. When the volcanoes cooled the atmosphere and oceans froze again at the poles, this moved them to their current positions. It also caused the extinction of the hypothesized alien colony. These papers are dated but indicate how the hypotheses of polar wander explain many of the fluvial and glacial formations on Mars.
