International audience Analyzing chemical composition of the lunar surface imparts knowledge about origin and evolution the Moon. Among the scientific instruments selected for investigation onboard the Russian Luna-Resurs mission the gas-chromatograph mass spectrometer complex will investigate volatiles including water in the lunar soil and exosphere in situ. Since available lunar samples originate from a restricted area near the equator, Luna-Resurs landing near the lunar South Pole provides access to lunar soil of a very different area, and being near the pole lots of volatiles are expected to be frozen in to soil. We developed a compact time-of-flight mass spectrometer (the neutral gas mass spectrometer, NGMS) that is coupled with a gas chromatograph (GC) to investigate volatile fraction of lunar regolith.
