NASA Astrobiology

Astrobiologists address three fundamental questions: How does life begin and evolve? Is there life elsewhere in the universe? What is the future of life on Earth and beyond? As part of a concerted effort to address this challenge, the National Aeronautics and Space Administration (NASA) established the NASA Astrobiology Institute in 1998 as an innovative way to develop the field of astrobiology and provide a scientific framework for flight missions. NAI is a virtual, distributed organization of competitively-selected teams that integrate astrobiology research and training programs in concert with the national and international science communities.
