Website migration in progress

This website is currently under construction as we migrate content from the previous SBAG website. Please check back soon for updates and new content, and please be patient if you come across any broken links or missing pages. If you have any questions or would like to contribute content, please contact Ben Cassese at benjamin (dot) cassese (at) cfa.harvard.edu.

The Small Bodies Assessment Group (SBAG) was established by NASA in March 2008 to identify scientific priorities and opportunities for the exploration of asteroids of all types, comets, interplanetary dust, interstellar objects, small satellites, centaurs, trans-Neptunian objects, Kuiper belt objects, dwarf planets, meteoroids, meteorites, and returned samples from any of these bodies. Starting in April 2026, SBAG is evolving into a independent, community-led, interdisciplinary body dedicated to advancing space exploration, fundamental research and analysis, technology, resource utilization, and planetary defense objectives related to small bodies across the Solar System. SBAG continues to serve as a community-based forum to provide scientific input for planning and prioritizing the exploration of small bodies throughout the Solar System.

The SBAG is open to all interested members of the small bodies community and is led by a steering committee. 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 would like to receive updates about SBAG activities, sign up for the new SBAG community Google group. The former SBAG listserv hosted by the LPI is being retired. If you'd like to join the SBAG Google group but don't see a "join" button, please email terik.daly@jhuapl.edu to be added.
