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.

Announcement: SBAG Early-Career Travel Support and Lightning Talks

The next meeting of the Small Bodies Assessment Group will be held at the Lunar and Planetary Institute on January 29–31, 2019. We want to make you aware of some opportunities for students and early-career scientists and engineers. Please pass along to relevant colleagues/students.

Early career travel support: We are planning to offer limited U.S. travel support for early career scientists to participate in the SBAG 20 meeting, to be held at the Lunar and Planetary Institute on January 29–31, 2019. Interested undergraduate students, graduate students, postdocs, and other early career scientists (within 5 years of PhD/MS/BS) should submit a letter and a CV to SBAG Early Career Secretary Hannah Susorney ( by COB (5 pm Eastern time) November 21, 2018. 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 (~10–15 minutes) of their SBAG-relevant work at the SBAG 20 meeting.

Lightning Talks/Poster Session: We are providing time on the agenda for early-career scientists and engineers present at the meeting to introduce themselves and their research to the community. Lightning talks will be 3 minutes each, with the possibility of a small poster session to showcase your work. If you are interested in participating in lightning talks, please contact the early-career secretary Hannah Susorney ( before January 18, 2019 to secure a spot.
