Chandrayaan-2 cruises to reach the moon by August 20 and drop a lander called Vikram on the Earth's sole satellite on September 7, Google on Monday celebrated the 100th birthday of Dr Vikram Sarabhai - father of the Indian space programme "with a Doodle". "There are some who question the relevance of space activities in a developing nation. To us, there is no ambiguity of purpose. We do not have the fantasy of competing with the economically advanced nations in the exploration of the moon or the planets or manned space-flight," Vikram emphasized the importance of a space programme during his successful dialogues with the Indian government. "But we are convinced that if we are to play a meaningful role nationally, and in the community of nations, we must be second to none in the application of advanced technologies to the real problems of man and society," he noted.
