Special Sessions are open sessions intended for observatories, missions, facilities, and major projects to present and discuss scientific results and plans. Special Sessions can also be used for discussion of education, history, community, and state-of-the-profession topics. There is no mandated format, and Special Sessions may feature multiple speakers, a panel discussion, or other presentation formats. Contributed talks are listed in the main conference program. Special Sessions are run just like normal oral sessions and hence hybrid or virtual participation is currently not permitted for Special Sessions.
