With the dawn of the new millennium, a renaissance began in the field of lunar exploration. Many countries and international organisations started spacecraft programmes to explore the Moon. They include the European Space Agency (ESA), Japan, China, the United States and Russia. India's Chandrayaan-1 too is the result of this great revival of humanity's interest in exploring the Moon.
As part of this renewed interest about the Moon, ESA launched SMART-1 in 2003, Japan launched Kaguya in September 2007, China launched Chang'e-1
in October 2007 and India launched Chandrayaan-1 in October 2008.
In 2009, The US launched Lunar Reconnaissance Orbiter as well as Lunar Crater Observation and Sensing Satellite (LCROSS) . All these Spacecraft sought to find answers to many interesting questions about the moon that haunt the humanity even today.
