India is Exploring the Moon
The MoonIndia launched its first unmanned spacecraft to explore the Moon on October 22, 2008.
The Indian Space Research Organisation (ISRO) calls the
Moon flight project Chandrayan Pratham, which has been translated as First Journey to the Moon or Moonshot One in ancient Sanskrit.The 1,157-lb. Chandrayan-1 was launched on a two-tyear mission on one of India's own Polar Satellite Launch Vehicle (PSLV) space rockets from the Sriharikota Space Center in southern India.
The spacecraft circled Earth in a geosynchronous transfer orbit (GTO) from where it flew on out into a polar orbit of the Moon some 60 miles above the lunar surface.
The Chandrayan mission will send back to Earth high-resolution 3-D images of the moon's surface including the shadowy polar regions. It is searching for evidence of water or ice. It also will try to identify the chemical breakdown of some lunar rocks.
Chandrayan-1 carries X-ray and gamma-ray spectrometers sending data to scientists on Earth for use in a high-resolution digital map of the lunar surface. Its remote-sensing instruments are sensitive to visible light, near-infrared light, and low-energy and high-energy X-rays.
Shar Space Launch Center on Sriharikota Island off India's east coast state of Andhra Pradesh is used by ISRO to launch spacecraft on PSLV and other rockets.Chandrayaan-1 has payloads from the United States and European countries Germany, Britain, Sweden and Bulgaria. India plans to share its Moon data with NASA and other space agencies.
The European Space Agency (ESA) provided three science instruments for Chandrayan-1. They are identical to those already in orbit around the Moon on ESA's Smart 1 spacecraft, which is surveying chemical elements on the lunar surface.
The Indian lunar satellite also houses a U.S. radar instrument designed to locate water ice.
Previously, India has launched weather and communication satellites to Earth orbit.
Why send a probe to the Moon? While the South Asian nation has the second largest population on Earth, it is not a rich country with millions of uneducated and even homeless residents.
Like all other nations sending machines and people to space, India considers funding of its space program to be a matter of prestige. In making the announcement in 2003, Prime Minister Atal Behari Vajpayee said a Moon flight would showcase India's scientific capabilities.
A former science minster in the Indian government, physicist M.G.K. Menon told news media then that Chandrayan-1 would "excite the younger generation." Menon also said the Moon flight would have the effect of "enormously increasing the confidence of the nation.
" ISRO said Chandrayan-1 is the first mission in "India's foray into a planetary exploration era in the coming decades." Chandrayan-1 will be the "forerunner of more ambitious planetary missions in the years to come, including landing robots on the Moon and visits by Indian spacecraft to other planets in the Solar System."
Other nations have probed the Moon. The former Soviet Union and the United States conducted the earliest lunar exploration in the late 1950s and the 1960s. Soviet spacecraft were the first to fly by, then land on, and finally orbit the moon. The U.S. Apollo flights were the first manned missions to reach the moon, culminating with six missions that set down on the surface.
Much more recently, India's Asian neighbors, China and Japan, sent spacecraft to orbit the Moon in 2007.
