Moon occupies a special place for humans. As the closest celestial object to Earth and with the recent advances made in lunar exploration, Moon will continue to be an important object of study. The early Moon landings during the Apollo era were followed by a lull in lunar studies until the early 1990s with the launch of Clementine (USAF/NASA) followed by Lunar Prospector (NASA), SMART-1 (ESA), Kaguya (Japan),Chang’e missions (China), Chandrayaan-1 (India), Lunar Reconnaissance Orbiter (NASA), etc.
