Evaluating Biosignatures for Life Detection. [PDF]

Astrobiology, 2020
Conceptual frameworks are developed for evaluating the ability of different biosignatures to provide evidence for the presence of life in planned missions or observational studies. The focus is on intrinsic characteristics of biosignatures in space environments rather than on their detection, which depends on technology. Evaluation procedures are drawn

The Ladder of Life Detection. [PDF]

Astrobiology, 2018
We describe the history and features of the Ladder of Life Detection, a tool intended to guide the design of investigations to detect microbial life within the practical constraints of robotic space missions. To build the Ladder, we have drawn from lessons learned from previous attempts at detecting life and derived criteria for a measurement (or suite

Exploring Life Detection on Mars: Understanding Challenges in DNA Amplification in Martian Regolith Analogue After Fe Ion Irradiation. [PDF]

Life (Basel)
The search for life beyond Earth currently hinges on the detection of biosignatures that are indicative of current or past life, with terrestrial life being the sole known example.
