BANGALORE, India (Reuters) - India terminated its first mission to the moon on Sunday, a spokesman for the national space agency said, a day after scientists lost all contact with an unmanned spacecraft orbiting the moon. Our efforts to establish contact have failed. The mission has been terminated, said S. Satish, spokesman of the Indian Space Research Organisation (ISRO). There was no point continuing with the mission. Communications with the Chandrayaan-1 craft broke down early on Saturday. The cause of the malfunction is being investigated. The $79m mission was launched amid national euphoria last October. A vehicle landed on the moon a month later and sent back images of the lunar surface. But a crucial sensor in the main craft, orbiting the moon, malfunctioned in July, raising fears that the two-year mission might have to be curtailed. One of the missions main tasks was to look for Helium 3, an isotope which is very rare on earth but could be an energy source in the future in nuclear fusion. Satish said preparations had already begun for Chandrayaan-2, also an unmanned mission to the moon, which India hopes to launch by 2012. This would be a step toward achieving the ISROs goal of sending a manned mission into space in four years time and eventually sending a spacecraft to Mars.
