Chandrayaan-1 (Sanskrit: चंद्रयान-१, lit: moon vehicle[3][4] [pic]pronunciation (help·info)) was India's first unmanned lunar probe. It was launched by the Indian Space Research Organisation in October 2008, and operated until August 2009. The mission included a lunar orbiter and an impactor. India launched the spacecraft with a modified version of the PSLV, PSLV C11[2][5] on 22 October 2008 from Satish Dhawan Space Centre, Sriharikota, Nellore District, Andhra Pradesh, about 80 km north of Chennai, at 06:22 IST (00:52 UTC).[6] Former prime minister Atal Bihari Vajpayee announced the project on course in his Independence Day speech on 15 August 2003.

The power plant consists of one 440 N engine and eight 22 N thrusters. Fuel and oxidizer are stored in two tanks of 390 litres each.[21][22]
Navigation and control The craft is 3-axis stabilized with two star sensors, gyros and four reaction wheels. The craft carries dual redundant bus management units for attitude control, sensor processing, antenna orientation, etc.[21][22]

Specific areas of study

• High-resolution mineralogical and chemical imaging of the permanently shadowed north- and south-polar regions • Searching for surface or sub-surface lunar water-ice, especially at the lunar poles • Identification of chemicals in lunar highland rocks • Chemical stratigraphy of the lunar crust by remote sensing of the central uplands of large lunar craters, and of the South Pole Aitken Region (SPAR), an expected site of interior material • Mapping the height variation of features of the lunar surface • Observation of X-ray spectrum greater than 10 keV and stereographic coverage of most of the Moon's surface with 5 m resolution • Providing new insights in understanding the Moon's origin and evolution


The scientific payload had a total mass of 90 kg and contained five Indian instruments and six foreign instruments.
