NASA's Asteroid Initiative has two main parts: a mission to identify, robotically capture, and redirect a small asteroid into a stable lunar orbit; and a grand challenge to promote global collaboration in finding all asteroid threats to human populations and know what to do about them.

Why Do We Explore?
From the time of our birth, humans have felt a primordial urge to explore -- to blaze new trails, map new lands, and answer profound questions about ourselves and our universe.

Human Exploration and Operations at NASA
The Human Exploration and Operations (HEO) Mission Directorate provides the Agency with leadership and management of NASA space operations related to human exploration in and beyond low-Earth orbit. HEO also oversees low-level requirements development, policy, and programmatic oversight. The International Space Station, currently orbiting the Earth with a crew of six, represents the NASA exploration activities in low-Earth orbit.
Exploration activities beyond low Earth orbit include the management of Commercial Space Transportation, Exploration Systems Development, Human Space Flight Capabilities, Advanced Exploration Systems, and Space Life Sciences Research & Applications.
The directorate is similarly responsible for Agency leadership and management of NASA space operations related to Launch Services, Space Transportation, and Space Communications in support of both human and robotic exploration programs.
The HEO library contains links to directorate, program and project documents, as well as historical events and activities.
Reports: Read reports and documents on a variety of exploration-related topics.
