The 2021 American Geophysical Union (AGU) Fall Meeting took place Dec 13–17 in New Orleans, LA and "Online Everywhere." Leveraging AGU's hybrid conference format, GST's NASA Science Support Office team coordinated the first-ever NASA Science exhibit with both in-person and virtual components. In another first, NASA's AGU virtual exhibit was available to the broader public. Exhibit centerpieces included a NASA Science Theater and a Learning Area incorporating presentations given live onsite and available on-demand online. GST Scientific Visualization Studio staff ran the Science Theater's hyperwall onsite, and other GST staff members presented in the exhibit and AGU's Scientific Program.
