Inside the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida, members of the Mass Spectrometer observing lunar operations (MSolo) team prepare MSolo flight hardware for shipment in preparation for launch in 2022. MSolo is a commercial off-the-shelf mass spectrometer modified to work in space and it will help analyze the chemical makeup of landing sites on the Moon, as well as study water on the lunar surface. MSolo is part of four of the agency’s Commercial Lunar Payload Delivery Service missions where under the Artemis program, commercial deliveries beginning in 2022 will perform science experiments, test technologies and demonstrate capabilities to help NASA explore the Moon and prepare for human missions.
