![]() ![]() The second phase is producing levels of O² in the atmosphere that would allow humans and other large mammals to breath normally. This warming phase is relatively easy and quick, and could take ~100 years. ![]() The first phase is warming the planet from the present average surface temperature of -60° C to a value close to Earth's average temperature to +15° C, and recreating a thick CO² atmosphere. "Terraforming Mars can be divided into two phases. In their paper, the two researchers present a timeline for the terraforming of Mars that includes a Warming Phase and an Oxygenation Phase, as well as all the necessary steps that would precede and follow.Īs they state in their paper's Introduction: The former paper was produced by Aaron Berliner from the University of California, Berkeley, and Chris McKay from the Space Sciences Division at NASA Ames Research Center. The second, titled "Mars Terraforming – the Wrong Way", rejects the idea of terraforming altogether and presents an alternative. The first, titled "The Terraforming Timeline", presents an abstract plan for turning the Red Planet into something green and habitable. Such were the questions dealt with by two papers presented at NASA's "Planetary Science Vision 2050 Workshop" last week (Mon. ![]()
