| Time | Topic | Location |
|---|---|---|
| 10:00am ‑ 11:30am | HEAD: Foundations for Discovery: A Coordinated Fleet Approach to NASA Astrophysics | Conference Center 212 |
| Summary | This session will discuss findings that demonstrate that most decadal science questions are optimally addressed through a coordinated fleet of∼ $1–2B missions (or flaglets) with a broad suite of capabilities, a significant guest investigator component, and operating concurrently with flagship missions to enable comprehensive, coordinated observations across the electromagnetic spectrum. |
