Descriere completă

Scientists classify comets and asteroids that pass within 28 million miles of Earth''s orbit as near-Earth objects (NEOs). Asteroids that collide and break into smaller fragments are the source of most NEOs, and the resulting fragments bombard the Earth at the rate of over 100 tons a day. Although the vast majority of NEOs that enter Earth''s atmosphere disintegrate before reaching the surface, those larger than 100 meters (328 feet) may survive the descent and cause destruction in and around their impact sites. Furthermore, even smaller objects that disintegrate before reaching Earth''s surface can cause significant damage. This book examines NASA''s NEO Program and assesses the Agency''s progress toward meeting statutory and other Program goals. Specifically, it reviews NASA''s allocation and use of resources and plans for the future of the Program.
