Our Roy Chapman Andrews Society
Distinguished Explorer 2023
Dr. Sarah Stewart Johnson
American biologist, geochemist, astronomer, and planetary scientist.
Principal investigator, Johnson Biosignatures Lab, Georgetown University
Keynote Lecture:
“Contending with the Truly Alien”
Dr. Johnson is the Provost’s Distinguished Associate Professor of Planetary Science at Georgetown University and a visiting scientist at NASA’s Goddard Space Flight Center.
She holds a B.A. in mathematics and environmental studies from Washington University in St. Louis, a second B.A. in philosophy, politics, and economics and M.Sc. in biology from Oxford University, where she studied as a Rhodes Scholar, and a Ph.D. in planetary science from the Massachusetts Institute of Technology.
Prior to joining the Georgetown faculty, she was a Junior Fellow in the Harvard Society of Fellows. Dr. Johnson’s research focuses on understanding the presence and preservation of biosignatures within planetary environments. She is also involved in planetary exploration, analyzing data from current spacecraft, and devising new techniques for future missions.
Some of her recent projects include searching for signs of habitability on Mars with the Curiosity Rover, studying the limits of life in Antarctica, assessing how biology affects patterns of mineralization in Mars analog environments, and helping to develop sequencing as a tool for spaceflight.

“Sarah Stewart Johnson interweaves her own coming-of-age story as a planetary scientist with a vivid history of the exploration of Mars in this celebration of human curiosity, passion, and perseverance.” — Alan Lightman, author of Einstein’s Dreams
NAMED ONE OF THE BEST BOOKS OF THE YEAR BY The New York Times Book Review – Times (UK) – Library Journal
“Lovely… Johnson’s prose swirls with lyrical wonder, as varied and multi-hued as the apricot deserts, butterscotch skies and blue sunsets of Mars.” — Anthony Doerr, The New York Times Book Review
Mars was once similar to Earth, but today there are no rivers, no lakes, no oceans. Coated in red dust, the terrain is bewilderingly empty. And 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, one that would inspire humankind as much as any discovery in the history of modern science.
In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.
