Letter from the Director
We live in exciting times. From an astrobiological perspective, the enduring triumph of the Mars Exploration Rovers, Spirit and Opportunity , the promise of Cassini-Huygens, and the accumulating catalog of extrasolar planets and planetary systems, are obvious highlights. We also live in interesting times. The transformation of NASA from an agency focused on the origin, future, and occurrence of life in the Universe (NASA 2003 Strategic Plan) to one with a novel Vision for Space Exploration is still underway.
The broad astrobiological goals, articulated in the Strategic Plan and the Astrobiology Roadmap, remain the...

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
