Masking
The latest update on the Centers for Disease Control and Prevention (CDC) COVID-19 Community Levels Map shows that the DC region is in LOW community transmission level. NASA guidance makes wearing a mask indoors optional. Even if masking isn't required, participants may always choose to wear a mask based on personal preference or assessment of personal risk. Please know that choice is fully supported.
