Virtual Press Conferences at 2023 Meeting of Division for Planetary Sciences and Europlanet Science Congress

The 55th annual meeting of the American Astronomical Society (AAS) Division for Planetary Sciences (DPS), joint with the Europlanet Science Congress (EPSC), is being held in San Antonio, Texas, and virtually Sunday, 1 October, through Friday, 6 October 2023. The AAS/DPS offers complimentary press registration to bona fide working journalists and public information officers (PIOs); see details below. We will hold press conferences via Zoom on Monday, 2 October, and Wednesday, 4 October, to showcase some of the most exciting discoveries being presented at the meeting. 

In addition to the briefings, the meeting features a rich science program, including plenary sessions with live panel discussions, oral presentations, a virtual poster session, and Q&A/discussions with presenters and fellow attendees via Slack. 

Nearly 900 planetary scientists, journalists, and others are already registered for the conference. The meeting hashtag is #DPSEPSC2023; you may also wish to follow @DPSMeeting and @AAS_Press on Twitter.

Press Registration 

To request complimentary press registration, first check our eligibility criteria, then send an email message to DPS Press Officer Teddy Kareta (tkareta@lowell.edu) with your name and media affiliation (or “freelance” if applicable). Upon confirming your eligibility, he’ll email you a special promotional code that you can use to register for the meeting the same way regular attendees do, i.e., via the DPS-EPSC 2023 registration page. For step-by-step instructions on what to do next, see the DPS 55 press information page

Please register as soon as possible. Note that if you are attempting to register after the meeting is under way, we may not be able to process your registration in time for you to attend that day’s events.

Press Conference Schedule, Topics & Speakers 

Press conferences will be conducted via Zoom for press registrants and any other meeting registrants wishing to attend. They’ll also be live-streamed on the AAS Press Office YouTube channel for other interested people who have not registered for the meeting. You will not be able to ask questions via YouTube — to do that, you need to register for the meeting and join the briefings via Zoom. The briefings will be archived on the AAS Press Office YouTube channel afterward. 

Following is the press-conference program, which remains subject to change. Corresponding abstract numbers are shown in [square brackets]. Briefings are scheduled as follows (all times are CDT = UTC – 5 hours); each briefing will last approximately 1 hour, including time for Q&A: 

  • Monday, 2 October, 12:15 pm CDT 
  • Wednesday, 4 October, 12:15 pm CDT 

All findings are embargoed until the time of presentation at the meeting. “Time of presentation” means the start time of the session in which the paper will be given, or the start time of the corresponding press conference (if any), whichever comes first. See the complete AAS/DPS embargo policy for more information. 

Note: All new discoveries are subject to confirmation by independent teams of scientists. Inclusion here does not imply endorsement by the American Astronomical Society or the Division for Planetary Sciences. The AAS and DPS do not endorse individual scientific results.

The Division for Planetary Sciences (DPS), founded in 1968, is the largest special-interest Division of the American Astronomical Society. Members of the DPS study the bodies of our own solar system, from planets and moons to comets and asteroids, and all other solar-system objects and processes. With the discovery that planets exist around other stars, the DPS has expanded its scope to include the study of extrasolar planetary systems as well. 

The American Astronomical Society (AAS), established in 1899, is a major international organization of professional astronomers, astronomy educators, and amateur astronomers. Its membership of approximately 8,000 also includes physicists, geologists, engineers, and others whose interests lie within the broad spectrum of subjects now comprising the astronomical sciences. The mission of the AAS is to enhance and share humanity’s scientific understanding of the universe as a diverse and inclusive astronomical community, which it achieves through publishing, meetings, science advocacy, education and outreach, and training and professional development.

The Europlanet Society was formed in 2018 to promote the advancement of European planetary science and related fields for the benefit of the community and is open to individual and organizational members.
