The launch vehicle is called the Polar Satellite Launch Vehicle [PSLV]:
Total launches 13
Successes 11
The PSLV has four stages using solid and liquid propulsion systems alternately. The first stage is one of the largest solid-fuel rocket boosters in the world...

Chandrayaan-1: "The spacecraft bus is roughly a 1.5 meter cube with a dry weight of 523 kg. It is based on the Kalpansat meteorological satellite. It will also carry a 30 kg probe designed to be released from the spacecraft and penetrate the lunar surface."

And:
- "The Terrain Mapping Camera (TMC) has 5 meter resolution and a 40 km swath in the panchromatic band and will be used to produce a high-resolution map of the Moon.
The Hyper Spectral Imager (HySI) will perform mineralogical mapping in the 400-900 nm band

- The Lunar Laser Ranging Instrument (LLRI) will determine the surface topography.

- an X-ray flourescence spectrometer, will have three components: an Imaging X-ray Spectrometer (CIXS) covering 1 - 10 keV with a ground resolution of 10 km, a High Energy X-ray/gamma ray spectromenter (HEX) for 10 - 200 keV measurements with ground resolution of about 20 km, and a Solar X-ray Monitor (SXM) to detect solar flux in the 2 - 10 keV range.
...
Total cost of the mission is estimated at INR 3.8 billion ($83 million U.S.). "

" Specific areas of study

High resolution mineralogical and chemical imaging of permanently shadowed north and south polar regions

Search for surface or sub-surface water-ice on the moon, specially at lunar pole

Identification of chemical end members of lunar high land rocks

Chemical stratigraphy of lunar crust by remote sensing of central upland of large lunar craters, South Pole Aitken Region (SPAR) etc., where interior material may be expected
