The Biology of Biosignature Detection

July 17 - 21, 2023
California Institute of Technology - Pasadena, CA 91125

Workshop Overview:

The current framework for life detection for Mars exploration uses the ancient
biosignatures paradigm where robust organics and former lacustrine environments
provide assessments of habitability. This framework does not provide the science
community with direct evidence of extant life potentially inhabiting these regions.
With the recent Planetary Science and Astrobiology Decadal Survey emphasizing a focus
on extant life searches, it is critical to
revisit and update our scientific investigations and datasets to more definitively interpret
potential extant biology outside of our terrestrial biosphere.

From their fieldwork and laboratory experiences this team will develop and
showcase geobiological, geochemical, isotopic, spectroscopic, and spatial measurements
of cellular life. Using these measurements, the study will develop a new framework for biological validation for future missions with
science driving the instrument development.
