DARPA hopes to terraform Mars with human-engineered organisms

Mars may look like an inhospitable and barren landscape, but a new program underway at the Pentagon’s advanced research division is looking to create engineered organisms that can eventually transform the Red Planet into something more Earth-like. If humans are ever to live on Mars without being confined inside of man-made structures, the planet’s climate and surface would need to be radically altered. It features potentially dangerous planet-wide dust storms, low gravity, and its thin atmosphere, plus increased distance from the sun, makes it an especially cold place for any humans to settle – the average temperature is -50 degrees Celsius (-122 degrees Fahrenheit), according to NASA...read more>>>...
