NEW DELHI - India switched off its moon rover, the first craft to reach the lunar south poll, after it completed its two-week assignment conducting experiments, the country's space agency said. "Else, it will forever stay there as India's lunar ambassador." By landing on the moon, India joined the United States, China and the former Soviet Union. Pragyan travelled over 100 m (330 feet), confirming the presence of sulphur, iron, oxygen and other elements on the moon, ISRO said. "The satellite is healthy" and in earth orbit, ISRO said on Sunday, as it prepares for its 1.5 million-km (930,000-mile) journey.
