Principal investigator, Dr. Janine Captain, attaches a mass spectrometer sensor to electronics inside a vacuum chamber in the Space Station Processing Facility high bay at NASA’s Kennedy Space Center on Dec. 12, 2018. The Mass Spectrometer observing lunar operations (MSolo) instrument is a commercial off-the-shelf mass instrument modified to work in space, and can identify molecules at lunar landing sites. These MSolo instruments are part of NASA’s efforts to return to the Moon with the Commercial Lunar Payload Services Landers Program.
