The NASA Astrobiology Roadmap provides guidance for research and technology development across the NASA enterprises that encompass the space, Earth, and biological sciences. The ongoing development of astrobiology roadmaps embodies the contributions of diverse scientists and technologists from government, universities, and private institutions. The Roadmap addresses three basic questions: how does life begin and evolve, does life exist elsewhere in the universe, and what is the future of life on Earth and beyond? Seven Science Goals outline the following key domains of investigation: understanding the nature and distribution of habitable environments in the universe, exploring for habitable environments and life in our own Solar System, understanding the emergence of life, determining how early life on Earth interacted and evolved with its changing environment, understanding the evolutionary mechanisms and environmental limits of life, determining the principles that will shape life in the future, and recognizing signatures of life on other worlds and on early Earth. For each of these goals, Science Objectives outline more specific high priority efforts for the next three to five years. These eighteen objectives are being integrated with NASA strategic planning.
美国国家航空航天局（NASA）的天体生物学路线图为NASA各部门（涵盖空间科学、地球科学和生命科学）的研究与技术发展提供指导。天体生物学路线图的持续制定体现了来自政府、大学和私营机构的众多科学家和技术专家的贡献。该路线图解决了三个基本问题：生命如何起源和演化、宇宙其他地方是否存在生命，以及地球及其他星球上生命的未来如何？七个科学目标概述了以下关键研究领域：了解宇宙中宜居环境的性质和分布、探索我们太阳系中的宜居环境和生命、了解生命的起源、确定地球上早期生命如何与其不断变化的环境相互作用和演化、了解生命的进化机制和环境限制、确定塑造未来生命的原则，以及识别其他星球和早期地球上生命的特征。针对每个目标，科学目标概述了未来三到五年更具体的高优先级工作。这18个目标正与NASA的战略规划相结合。
