Chandrayaan 1 is an Indian Space Research Organization (ISRO) mission to orbit the moon for two years, gathering scientific information and testing India's space capabilities. Based upon the Kalpansat weather satellite, it is a 1.5 meter bus weighing approx. 523 kg. Chandrayaan carries a 29kg Moon Impact Probe (MIP) and a 55kg scientific payload.

The spacecraft was successfully launched on PSLV on October 22nd 2008. A power supply failure caused premature termination of the mission in August of 2009. At that time Chandrayaan-1 was expected to crash into the moon in about 1000 days.

Instrumentation

The scientific payload consists of the following:

Indigenous

Terrain Mapping Camera (TMC) with a 5 meter resolution.
Hyper Spectral Imager (HySi) for mineralogical mapping in the 400-900 nanometer band. Spectral resolution of 15 nanometers. Spacial resolution of 80 meters.
Lunar Laser Ranging Instrument (LLRI) for mapping lunar topography.
High Energy X-ray/gamma ray spectrometer (HEX). 30 - 250 keV range. Designed to detect the decay products of Uranium and Thorium.
Moon Impact Probe (MIP). 29 kg released from a 100km orbit.

Foreign

Imaging X-Ray Spectrometer (C1XS). 1-10 keV range fluorescence. Ground resolution of 10km. Measures abundance of elemental Mg, Al, Si, Ca, Fe, and Ti on the lunar surface. Through ESA.
