Topic in short :

Recently scientists at NASA spotted Chandrayaan 1 after being lost for 8 years.

Chandrayaan 1 was India’s FIRST mission to moon. Scientists at ISRO wanted to explore the early history of the solar system and that of the earth. This led to the idea of scientific mission to the moon and the then Prime Minister Sir. Atal Bihari Vajpayee announced the Chandrayaan project in his independence day speech on 15th August 2003.

India successfully launched Chandrayaan 1 on October 22, 2008 from Satish Dhawan Space Centre SHAR, Sriharikota.

The spacecraft was orbiting around the Moon at a height of 100 km from the lunar surface for chemical, mineralogical and photo-geologic mapping of the Moon.

One of the objectives was to prepare a three-dimensional atlas (with high spatial and altitude resolution) of both near and far side of the moon. It aimed at conducting chemical and mineralogical mapping of the entire lunar surface for distribution of mineral and chemical elements such as Magnesium, Aluminium, Silicon, Calcium, Iron and Titanium as well as high atomic number elements such as Radon, Uranium & Thorium with high spatial resolution.
