Instruments for the Mass Spectrometer observing lunar operations (MSolo) are in view inside the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on Sept. 25, 2020. 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. This work is preparing MSolo hardware for a robotic mission as part of the Commercial Lunar Payload Services (CLPS) launching to exploring Lacus Mortis, a large crater on the near side of the Moon in 2021. A future mission will send a mobile robot named the Volatiles Investigating Polar Exploration Rover (VIPER) to the Moon to prospect for water. VIPER will have several instruments that will allow it to detect and sample water including MSolo, the Neutron Spectrometer System, the Near Infrared Volatiles Spectrometer System and The Regolith and Ice Drill for Exploring New Terrain (TRIDENT).
