The goal of NASA's Exobiology Program is to understand the origin, evolution, and distribution of life, and life-related molecules, on Earth and throughout the universe. Emphasis is focused on determining how the rate and direction of these processes were affected by the chemical and physical environment of the evolving planet, as well as by planetary, solar, and astrophysical phenomena. This is accomplished by a multi-disciplinary program of research conducted by over 60 principal investigators in both NASA and university laboratories. Major program thrusts are in the following research areas: biogenic elements; chemical evolution; origin of life; organic geochemistry; evolution of higher life forms; solar system exploration; and the search for extraterrestrial intelligence (SETI).
美国国家航空航天局（NASA）的外星生物学计划的目标是了解地球上以及整个宇宙中生命及与生命相关分子的起源、演化和分布。重点在于确定这些过程的速率和方向是如何受到不断演化的行星的化学和物理环境，以及行星、太阳和天体物理现象的影响。这是通过NASA和大学实验室的60多位首席研究员开展的多学科研究计划来实现的。该计划的主要研究方向包括以下几个领域：生物成因元素；化学演化；生命起源；有机地球化学；高等生命形式的演化；太阳系探索；以及搜寻地外智慧生命（SETI）。
