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.

Tentative agenda

The 17th SBAG meeting is now available for sign up on the NASA Conference Tracking System for those of you who must request approval for attendance on that system. It is NCTS #29569-17.

Early career travel support: We are planning to offer limited U.S. travel support for early career scientists to participate in the SBAG 17 meeting, to be held at the NASA Goddard Space Flight Center in Greenbelt, MD on June 12–14, 2017.  Interested undergraduate students, graduate students, postdocs, and other early career scientists (within 3 years of PhD/MS/BS) should submit a letter and a CV to SBAG Early Career Secretary Angela Stickle ( by COB (5 pm Eastern time) May 5, 2017. Included in the letter, which must not exceed 2 pages, should be a demonstration of financial need and an explanation of how the applicant’s work relates to the purposes of the SBAG. The letter and CV should be combined into a single PDF document for submission by e-mail attachment.  Recipients of travel support will be expected to give a short presentation of their SBAG-relevant work at the SBAG 17 meeting.

Early career lightning talks:  We will be providing opportunities for early-career scientists and engineers to give a short (3 minute) presentation about their research at the meeting. If you are interested in giving a lightning talk, please email SBAG Early-career secretary Angela Stickle (
