The primary objectives of Chandrayaan are:
1. To expand scientific knowledge about the moon
2. To upgrade India's technological capability
3. To provide challenging opportunities for planetary
    research to the younger generation of Indian scientists.
The main objective was to design, develop, launch and orbit a spacecraft around the Moon using an Indian-made launch vehicle.
                                                                                                    Chandrayaan aims to achieve these well defined objectives through high resolution remote sensing of the moon in the visible, near infrared, microwave and X-ray regions of the electromagnetic spectrum.

With this, preparation of a 3-dimensional atlas of the lunar surface and chemical mapping of entire lunar surface is envisaged.
The results expected from the orbiter with the instruments on-board are:
    • Chemical and mineralogical mapping of the entire lunar surface at high spatial resolution, mapping particularly the chemical elements Magnesium, Aluminium, Silicon, Calcium, Iron, Titanium, Radon, Uranium, & Thorium.
    • The impact of a sub-satellite (Moon Impact Probe — MIP) on the surface on the Moon as a fore-runner to future soft-landing mission.
      Some other scientific areas of study for the orbiter are:
    • High-resolution mineralogical and chemical imaging of the permanently shadowed north and south polar regions.
    • Search for surface or sub-surface water-ice on the Moon, especially at the lunar poles.
    • Identification of chemicals in lunar highland rocks.
    • To map the height variation of the lunar surface features.
    • To provide new insights in understanding the Moon's origin and evolution.

What is expected from Chandrayaan mission?
  After thousands of years of naked eye observations, 400 years of telescopic observations, a hundred odd years of astrophysical observations with spectroscopes and a half century of spacecraft...
