Small Bodies Assessment Group (SBAG)

The Small Bodies Assessment Group (SBAG) was established by NASA in March 2008 to identify scientific priorities and opportunities for the exploration of asteroids, comets, interplanetary dust, small satellites, and Trans-Neptunian Objects. The SBAG also provides scientific input on the utility of asteroids and comets in support of human space activities. The group has an open membership and a steering committee. Input from the scientific community is actively sought. The SBAG provides findings to NASA Headquarters, but does not make recommendations.

SBAG Charter

The SBAG is NASA's community-based forum designed to provide science input for planning and prioritizing the exploration of small bodies throughout the Solar System for the next several decades. It also provides input on how small bodies can be utilized in support of human space activities. The SBAG is open to all interested members of the small bodies community. The SBAG regularly evaluates the goals, objectives, investigations, and required measurements for the exploration of small bodies on the basis of the widest possible community outreach. If you are interested in becoming an SBAG member, please fill out the Indication of Interest Form.
