Chandrayaan-1

Astronomy
  • An Indian Moon probe, with European and NASA involvement, launched 2008 October by the Indian Space Research Organization into a circular polar orbit around the Moon; the name Chandrayaan is Hindi for ‘Moon Craft’. Its instruments included the Terrain Mapping Camera (TMC) to generate a 3-D map of the Moon; the Hyper Spectral Imager (HySI) for mineral mapping; the Lunar Laser Ranging Instrument (LLRI) for topographical mapping; the Miniature Synthetic Aperture Radar (Mini-SAR) to search for water ice at the Moon’s poles; and a set of X-ray spectrometers for mapping specific elements on the surface. In 2008 November the Moon Impact Probe (MIP) was released and hit the lunar surface near the Moon’s south pole. Contact was lost with Chandrayaan-1 in 2009 August.

Space Exploration
  • India's first mission to the Moon. The 1 380 kg spacecraft was launched successfully by a PSLV-C11 rocket on 22 October 2008 from Sriharikota. The spacecraft orbited the Moon at a height of 100 km and mapped the chemical composition of the Moon’s surface. The spacecraft carried 11 scientific instruments built in India, the USA, the UK, Germany, Sweden, and Bulgaria, which were also used in the search for surface or sub-surface ice, particularly at the poles, and to prepare a 3D map of the Moon’s topography. After the successful completion of all the major mission objectives, the orbit was raised to 200 km during May 2009. Chandrayaan-1 made more than 3 400 orbits around the Moon before the mission concluded when communication with the spacecraft was lost on 29 August 2009.
