Mars, the fourth planet from the Sun, has long captivated the curiosity of scientists. Some of the most intelligent minds agree that humankind should work towards occupying Mars. And there is a good reason for that. When life on Earth was evolving, Mars was going through significant climate change. Studying the red planet, both its past and present, can help us understand the details of the evolution of Earth and other planets in the solar system. One of the technologies that can help humans establish a base on Mars, fuel-generating microbes, was suggested in a Georgia Tech study led by Pamela Peralta-Yahya, associate professor in the School of Chemistry and Biochemistry.
