Area of Science:

  • Astrobiology
  • Planetary Science
  • Origin of Life Studies

Background:

  • Mars is the most promising planet for understanding chemical evolution and the origin of life.
  • Exobiological objectives for Mars exploration are crucial for scientific advancement.

Purpose of the Study:

  • To outline strategies for Mars exploration focused on exobiology.
  • To determine the abundance of biogenic elements and organic compounds.
  • To search for evidence of past and present life on Mars.

Main Methods:

  • A five-phase approach involving orbital reconnaissance, lander missions, critical in-situ experiments, sample return, and human exploration.
  • Utilizing remote sensing and in-situ analyses to characterize Martian sites.
  • Conducting experiments to identify organics, detect fossils, and search for extant life.

Main Results:

  • The proposed strategies share a common phased sequence for achieving exobiological objectives.
  • Each phase builds upon the previous one, from global reconnaissance to human exploration.
  • Critical experiments are designed to directly address the question of life on Mars.

Conclusions:

  • A systematic, multi-phase exploration strategy is essential for advancing Mars exobiology.
  • Combining robotic and human exploration is necessary for comprehensive understanding.
  • Mars holds significant potential for answering fundamental questions about life in the universe.
