NASA's JPL Caltech science team has spent years analyzing and researching data about Mars. The hope is that there is life beneath the Red Planet's surface and that this will further scientists' understanding of planetary evolution and, ultimately, of our galaxy.

In an interview with Interesting EngineeringJesse Tarnas, a planetary scientist at JPL Caltech and NASA post-doctoral fellow, discussed where we currently are in the search for life on Mars, the future of Martian habitation, and what that means for us here on Earth.

Tarnas explained that part of his motivation comes from, "The idea of us living in a future where humans are collectively inhabiting Earth in a much more honorable and sustainable way." He believes that many of the ways this could be possible, and how we could learn to do so, come from exploring space, and from learning to inhabit other planets, like Mars.
