“…the story of Mars is also a story about Earth: how we’ve sought another stirring of life in the universe, and what that search has come to mean. Mars has been our mirror, our foil, a telltale reflection of what has been deepest in our hearts. We have seen in Mars a utopia. A wilderness. A sanctuary. An oracle.

And tenderly, our human seeking has rushed to fill it,” writes Dr. Johnson in the book’s forward.

A former Rhodes Scholar and White House Fellow, she received her PhD from MIT and has worked on NASA’s Spirit, Opportunity, and Curiosity rovers. She is also a visiting scientist with the Planetary Environments Lab at NASA’s Goddard Space Flight Center.
Johnson’s lab focuses on detecting biosignatures, or traces of life, and is involved with analyzing data from current spacecraft and devising new techniques for future missions.
