For more information, please visit the Health & Safety Information Center webpage.

Virtual Participation
AAS 239 will be a return to in-person meetings. The Board of Trustees has decided to require full COVID-19 vaccination for all AAS 239 on-site attendees, staff, and support contractors without exception. Those who are not vaccinated and/or who opt not to travel are encouraged to register for the limited virtual meeting platform, which will enable remote participation — at a reduced registration rate — in key aspects of the conference such as plenary talks, iPosters, town halls, and press conferences. For more information, please visit the Health & Safety Information Center webpage.
