Therefore, one of the major goals for NASA’s human spaceflight program and the Asteroid Initiative is to identify these NEAs both from the standpoint of human exploration and planetary defense. These missions are particularly attractive as they will yield an unprecedented amount of knowledge about the formation of the solar system, provide a stepping-stone approach for future human exploration missions to Mars and beyond, identify materials for in situ resource utilization (ISRU), and test techniques for deflecting potentially hazardous objects that threaten Earth. In particular, NASA and the Japanese and European space agencies have begun expending serious effort to discover and identify appropriate NEA targets for a wide variety of spaceflight activities, including both robotic and human missions. presidential directive, the successful return of an asteroid sample by the Japanese spacecraft Hayabusa in 2010, and the high-visibility airburst impact event over Chelyabinsk, Russia, in 2013, scientific and exploration interest in near-Earth asteroids (NEAs) has never been greater.

(2015) Human exploration of near-Earth asteroids. Near-Earth asteroid targets suitable as destinations for human exploration tend to have orbits very similar to Earth’s, and also have a statistically greater chance of impacting our 855 Abell P. More recently, on June 18, 2013, President Obama gave NASA a Grand Challenge to “find all asteroid threats to human populations and know what to do about them.” This Grand Challenge, combined with the directive for a human NEA mission, forms the basis of NASA’s Asteroid Initiative ( /asteroidinitiative, accessed June 10, 2015) (Fig. This directive became part of the official National Space Policy of the United States of America as of June 28, 2010. In response to these findings, President Barack Obama directed NASA to include NEAs as destinations for future human exploration with the goal of sending astronauts to an NEA in the mid to late 2020s. In 2009, the Review of the United States Human Spaceflight Plans Committee, also known as the Augustine Commission, identified NEAs as high-profile destinations for human exploration missions beyond the Earth-Moon system as part of the “Flexible Path” approach ( pdf/384767main_SUMMARY%20REPORT%20-%20FINAL. In addition, human-led exploration missions to these destinations are now also being seriously considered. Robotic missions to near-Earth asteroids (NEAs) have already been completed by several space agencies, and subsequent robotic missions to these bodies are under development or consideration. INTRODUCTION Asteroids have generated significant worldwide interest in recent years as a result of flyby, rendezvous, and sample return missions. In lieu of an abstract, here is a brief excerpt of the content:ġ.
