• 14 Nov. 2008: First unmanned Indian Chandrayan in the orbit of Moon


• Moon Impact probe landed on the Moon from Chandrayan
  


• Indian tri-colour flag was placed on the Moon land


• India fourth country to register its presence on the Moon



• Chandrayan-II to be launched in 2012


• China, America and Japan are moving big space Projects so we have to compete and can not afford to remain backward in this direction: Dr Madhawan Nair


• No atmosphere in the Moon; its acceleration due to gravity is about 1/6 th of the Earth


• Chandrayan will take pictures of the Moon surface and prepare the 3-D globe map of the Moon with chemical composition of the surface


• Map will give the information about the possibility of water/ ice in the Moon as well as मिनरल्स


• A step towards possibility of bringing helium existing at the Moon in abundance to the earth in the future. Helium-3 is a an important source of clean energy. Indian scientists want to focus on this mission. They wish mining of the Moon's heleum to bring it on the Earth.
  


• Helium-3 is a scarce element on the Earth. This will be the clean source of energy without pollution. If it is brought from thr Moon; it will contribute to ease the problem of energy to a great extent.
  


• A major achievement to put Chandrayan in the Moon's orbit


• Cost is about 386 Cr





• Lunar ice is water ice that is hypothesied to exist on some part of the Moon. Discovered in 1998. Presently cost of taking 1 litre water in space is Rs 9.68 lakh. If existence of water on the Moon is proved, then it can be utilized for future space mission of the Moon. It will be thus great enthisuastic.




• 18 July, 2009 : Technical fault reported in the Star Sensor. Due to this, difficulty faced in tilting the Chandrayan towards Moon and focusing it on the Moon's surface. Star Sensor manages the direction of the satellite after evaluating the position of the stars. In the absence of it, scientists are managing this task with the help of gyroscope and Moon sensor. ISRO Chief Dr. Madhawan Nair is hopeful to rectify this fault within a week.
