Goal 1: Understand the nature and distribution of habitable environments in the Universe
Goal 2: Explore for past or present habitable environments, prebiotic chemistry and signs of life elsewhere in our Solar System
Goal 3: Understand how life originates from cosmic and planetary precursors
Goal 4: Understand how past life on Earth interacted with its changing planetary and Solar System environment
Goal 5: Understand the evolutionary mechanisms and environmental limits of life
Goal 6: Understand the principles that will shape the future of life, both on Earth and beyond
Goal 7: Determine how to recognize signatures of life on other worlds and on early Earth
