One of the most ambitious efforts by the developing nations to scale the moon was the Chandrayaan mission, launched by the Indian Space Research Organization. Its goal was to expand ISRO’s capabilities and to help resolve long standing questions about the moon's history. Chandrayaan-1 had deployed a powerful suite of instruments to map the lunar surface and search for the presence of radioactive isotopes. It also helped ISRO’s ground support, communications, and data reception and interpretation systems, and also increased India’s technical and scientific capabilities. However its star sensors failed in July, 2009.
