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[change | change source]

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 make a three-dimensional map of both the near and far sides of the Moon
    • for chemical and mineralogical mapping of the entire lunar surface at high spatial resolution, mapping particularly the chemical elements magnesium, aluminium, silicon, calcium, iron, titanium, radon, uranium, and thorium
  • 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
