Nanda Devi Plutonium Mission
The Nanda Devi Plutonium Mission was a joint operation by the United States Central Intelligence Agency (CIA) and the Indian Intelligence Bureau (IB) to spy on the nuclear developments being conducted in the Xinjiang Province of China. The agencies cooperated in October 1965 to install a nuclear-powered remote sensing station on the peak of Nanda Devi in the Uttarakhand Garhwal Himalayas. The mission failed after the plutonium powered Radioisotope Thermoelectric Generator was lost in the mountains because of a strong snowstorm.
