Chandrayaan-1 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 by a modified version of the PSLV, PSLV C11 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). The mission was a major boost to India's space program,[7] as India researched and developed its own technology in order to explore the Moon.[8] The vehicle was successfully inserted into lunar orbit on 8 November 2008.
Specifications
Mass - 1,380 kg at launch, 675 kg at lunar orbit, and 523 kg after releasing the impactor.
Dimensions - Cuboid in shape of approximately 1.5 m
Communications - X band, 0.7 m diameter dual gimballed parabolic antenna for payload data transmission. The Telemetry, Tracking & Command (TTC) communication operates in S band frequency.
Power - The spacecraft is mainly powered by its solar array, which includes one solar panel covering a total area of 2.15 x 1.8 m generating 750 W of peak power, which is stored in a 36 A·h lithium-ion battery for use during eclipses.
Propulsion - The spacecraft uses a bipropellant integrated propulsion system to reach lunar orbit as well as orbit and...
