[1] Properties of crater boguslawski in application to planned lunar infrared spectrometer (lis) measurements / A. Berezhnoy, A. Grumpe, N. Evdokimova et al. // The sixth Moscw System Symposium 6MS. — Moon. — Space Research Institute Moscow Russian Academy of Sciences, Moscow, 2015. — P. 6MS3–MN–19. Lunar Infrared Spectrometer (LIS) is an experiment onboard Luna-Glob (Luna 25) and Luna-Resource (Luna 27) Russian surface missions. It’s a pencil-beam spectrometer to be pointed by a robotic arm of the landing module. The spectrometers will provide measurements of selected surface areas in the spectral range of 1.15-3.3 μm. The spectral selection is carried out by acoustooptic tunable filter (AOTF), which scans the spectral range sequentially. Electrical command of the AOTF allows selecting the spectral sampling, and permits a random ac-cess if needed. One of the most impressive results of recent Moon studies is the discovery of water in the surface layer. The M3 spectrometer onboard Chandrayaan-1 discovered that significant part of Moon surface contains H2O/OH-bearing material. The M3 results are in line with earlier lunar observations, made in 1999 with the VIMS optical spectrometer from the Cassini spacecraft, and were confirmed by new SIM/Deep Impact mapping spectrometer observations. M3 was the first spectrometer, which carried out systematic mapping of the Moon in the IR and showed that hydrated mineral band at 3 μm is widely spread, especially at the polar regions. The IR measurements detect H2O and/or OH in the thin surface layer of the Moon regolith. The primary goal of the LIS experiment is to detect the regolith hydration at 3 μm, identifying its form from the shape of the spectrum, and to follow its changes during the day/shadow pattern. LIS will allow also to study the mineralogical composition from mineral spectral signatures within the spectral range, and will serve for se-lection of samples to be analyzed by other instruments. The crater Boguslawski was selected as a primary land-ing site for Luna-Glob mission. For this reason we performed detailed study of this crater.
