About the Meeting

NASA's Exoplanet Exploration Program Analysis Group (ExoPAG) will hold its twenty eighth meeting on October 1st immediately preceding the 55th Division for Planetary Sciences (DPS) Meeting. The 55th DPS Meeting will take place October 1-6, 2023 at the San Antonio Marriott Rivercenter in San Antonio, TX. This will be a hybrid meeting. The primary objective of the ExoPAG 28 meeting is to foster stronger connections between the astrophysics and planetary communities within the field of exoplanet science. With this overarching goal, the agenda features presentations that focus on synergies between planetary and astrophysics science and missions. The agenda will also include a few programmatic talks. The program will conclude with our regular business meeting.

Community Feedback

The Planetary and Exoplanet communities are invited to send proposed suggestions or proposed findings to the ExoPAG Executive Committee for review prior to the meeting via the anonymous online forms.
(See description of past findings for reference)
