"We know that Mars once had liquid substances flowing over its surface, but why do we think it was water? Could it not have been something else?"

Letter from the Director
I am very pleased to release this latest NAI Annual Report, covering the period from July 1, 2007 to June 30, 2008. We have modified the NAI website to make this report (and those of the past several years) more accessible and user friendly. In addition to viewing the Annual Report by team, as before, you can now also view it by Astrobiology Roadmap Goal and Objective, as well as by Tags associated with each Project Report.

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
