Molecular Water on Moon Surface Confirmed by Chandrayaan-2 Orbiter

Researchers with Indian Institute of Remote Sensing and U.R. Rao Satellite Centre, divisions of ISRO, confirm presence of lunar water H2O) in Current Science paper; Previous measurements taken during Chandrayaan-1 with Moon Mineralogy Mapper definitively prove existence of Hydroxyl (HO) but unable to differentiate from water; Imaging Infrared Spectrometer, with spectral range 0.8–5.0 μm in circular 100-km orbit since Sep 2019, provides clear evidence of H2O, varying by region with concentration in upper latitudes
