Book Description
Mars was once similar to Earth, but today there are no rivers, no lakes, no oceans. Yet multiple spacecraft are circling Mars, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium, and Mare Sirenum-- on the brink, perhaps, of a staggering find. Johnson tells the story of how she and other researchers have scoured Mars for signs of life. She interlaces her journey as a female scientist with tales of other seekers, to offer an unlikely natural history of a place where no human has ever set foot, while providing a vivid portrait of our quest to defy our isolation in the cosmos. -- adapted from jacket
