Chandrayaan-1
Chandrayaan-1 was India's first spacecraft launched to explore the Moon. It lifted off on 22 October 2008.[1] It was under the control of the Indian Space Research Organisation (ISRO). It was launched by a PSLV rocket. Chandrayaan 1 carried NASA's M1 Moon Mineralogy Mapper. The space mission was designed to last for two years.[2] In reality the mission lasted for 312 days. It mapped about 95% of the moon's surface.[3] On 29 August 2009 radio signals from Chandrayaan-I were lost.[4] The mission was considered ended at that point.[4] The lunar probe showed the presence of water on moon.

Goals
The mission had the following stated objectives, or goals:[5]
- to design, develop, launch and orbit a spacecraft around the Moon using an Indian-made rocket
- to conduct scientific experiments using instruments on the spacecraft:
- to increase scientific knowledge
- to test the impact of a sub-satellite (Moon Impact Probe – MIP) on the surface of the Moon to help prepare for future soft-landing missions
