Future of the Search for Life: Workshop Report

Area of Science:

• Astrobiology and planetary science, focusing on the search for extraterrestrial life.
• Interdisciplinary collaboration between scientists, engineers, and technologists.

Background:

• The "Future of the Search for Life" workshop convened over 100 experts in March-April 2022.
• The workshop focused on the intersection of life-detection science and technology for future space missions.

Purpose of the Study:

• To identify necessary advances in measurement and sampling technologies for in situ life detection within the Solar System.
• To explore promising biosignature measurement strategies, including dynamic disequilibrium, catalysis, and informational polymers.

Main Methods:

• Expert opinion gathering through a virtual workshop format.
• Breakout group discussions to identify measurement needs, knowledge gaps, and sample handling constraints for diverse extraterrestrial environments (Enceladus, Europa, Mars, Titan).

Main Results:

• Identification of dynamic disequilibrium, catalysis, and informational polymers as key targets for life detection.
• Recognition that future sample processing approaches will be more complex, often requiring fluid handling and progressing from nondestructive to destructive techniques.
• Highlighting technology gaps in sample acquisition, processing, and preservation to maintain sample integrity and optimize data acquisition.

Conclusions:

• Significant advancements in technology and sample processing are crucial for future in situ life detection missions.
• Unprecedented payload integration and early collaboration between scientists and engineers are essential for mission success.
