Terraforming Might Not Work on Mars, New Research Says
Published on July 30, 2018 at 06:50PM
Mars might not have the right ingredients to terraform into our planetary home away from home -- even with the recent discovery of liquid water buried near its south pole. From a report: Research published Monday in Nature Astronomy puts a kibosh on the idea of terraforming Mars. At the heart of the study is carbon dioxide. Carbon dioxide, a greenhouse gas, is abundant on Mars -- its thin atmosphere is made of the stuff, and the white stuff we often see on the surface is dry ice, not snow. CO2 is even trapped in the rocks and soil. That abundance has long fueled visions of a fantasy future where all that trapped carbon dioxide is released, creating a thicker atmosphere that warms the planet. SpaceX founder Elon Musk has even proposed nuking Mars to make this happen. But in this new study, veteran Mars expert Bruce Jakosky of the University of Colorado Boulder and Christopher S. Edwards of Northern Arizona University, surveyed how much carbon dioxide is available for terraforming the Red Planet. They combined Martian CO2 observations from various missions -- NASA's MAVEN atmospheric probe, the European Space Agency's Mars Express orbiter, as well as NASA's Odyssey and the Mars Reconnaissance Orbiter. The results throw shade on the dreams of futurists.
