The Search for the Fingerprints of Life on Mars Begins
NASA’s Astrobiology Institute (NAI) announced that the SETI Institute has been selected as a new member of theNAI for a 5-year research program, “Changing Planetary Environments and the Fingerprints of Life.”
Led by planetary geologist and Senior Research Scientist, Nathalie Cabrol, the team’s work will address key questions. How can we identify the signature of life not just here on Earth, but on Mars as well? How does a planet’s changing environment impact the evidence for life?
“I am absolutely thrilled that the SETI Institute is joining the NAI. In the next five years, along with our partner institutions, we will focus on decoding the fingerprints of life–the biosignatures–in extreme environments here on Earth to help us look for life on Mars. Our goal is to understand the survival of biosignatures from an early, wetter Mars to the harsh environment of the red planet today. Understanding the role that the changing Martian environment has had on biosignatures will inform us on how to recognize these signatures, and how to explore them. We bring to this ambitious quest new exploration tools and, with NASA’s Mars 2020 on the horizon, the timing could not be more perfect,” stated Cabrol. “Personally and professionally, this is a tremendously exciting project because we aim to develop a roadmap to biosignature exploration for Mars for future missions.”
“I am delighted at the news that the SETI Institute led team has been chosen as one of the new members in the NASA Astrobiology Institute. The team worked hard at putting together an outstanding proposal and it is a positive reflection on the process that is in place to review the proposals that their effort is recognized and rewarded by their professional peers. We look forward to an exciting five years of outstanding research under the aegis of this award,” said David Black, President and CEO of the SETI Institute.
To model and test strategies for biosignature detection, Cabrol’s team will conduct fieldwork in extreme environments on Earth that are analogous to sites on Mars where water once flowed. Fieldwork will be done at Yellowstone National Park, sites in California and Chile, Axel Heiberg Island in the high Arctic, and Western Australia. Each site is an analog to Mars: volcanic and hydrothermal terrain, lake sediments, evaporates, and perennial cold springs. Sites will be explored from satellites, air, ground, and at the microscopic level in the field and laboratory. Understanding how to integrate this multi-scale information will help scientists learn how to select the best sites for discovering biosignatures on Mars.
Cabrol assembled a diverse team of experts in planetary science, robotics, laboratory experimentation, and exploration to conduct fieldwork, analyze samples, and develop a biosignature roadmap to guide the search for life on Mars. In addition to more than a dozen scientists at the SETI Institute, her team brings together scientists from universities, government agencies and industry partners in the United States, Canada, Europe, Australia and South America. In the US, partners include Arizona State University, University of Montana, University of Tennessee, Carnegie Mellon, Georgia Institute of Technology, Honeybee Robotics, Pacific Northwest National Laboratory, and NASA Ames Research Center. Non-US partners include McGill University (Canada), Centro de Astrobiologia (CAB, Madrid, Spain), Deutscher Wetterdienst (Germany), Friedrich-Alexander University (Germany), and Campoalto for logistics in Chile. Over the next 5 years, more than twenty scientists will work together to help answer the question of where, what and how to search for the right rocks on Mars to discover the fingerprints of life on the red planet.
