On May 3, 2023, the United States Marine Band performed in the acoustic testing chamber at Goddard Space Flight Center in Greenbelt, Md., to see if it could reach the volume that the Plankton, Aerosol, Cloud and ocean Ecosystem (PACE) spacecraft would be exposed to when launched by rocket into orbit. As a part of the visit, musicians had the opportunity to test their sound in their instrument groups. Here, percussionists play as loud as they can while monitored by volume measuring devices.
