NASA NAI Astrobiology Strategy 2015

Astrobiology research sponsored by NASA focuses on three basic questions: How does life begin and evolve? Does life exist elsewhere in the Universe? What is the future of life on Earth and beyond? Over the past 50 years, astrobiologists have uncovered a myriad of clues to answering these Big Questions. This 2015 Astrobiology Strategy identifies questions to guide and inspire astrobiology research on each of these topics—in the lab, in the field, and in experiments flown on planetary science missions—over the next decade. The strategy also identifies major ongoing challenges that astrobiologists tackle as they attempt to answer these universal questions.

Astrobiology Primer 2.0

Astrobiology is the science that seeks to understand the story of life in our universe. Astrobiology includes investigation of the conditions that are necessary for life to emerge and flourish, the origin of life, the ways that life has evolved and adapted to the wide range of environmental conditions here on Earth, the search for life beyond Earth, the habitability of extraterrestrial environments, and consideration of the future of life here on Earth and elsewhere. It therefore requires knowledge of physics, chemistry, biology, and many more specialized scientific areas including astronomy, geology, planetary science, microbiology, atmospheric science, and oceanography.
