Dismissing suggestions that Chandrayaan-1 was an expensive mission, Isro today said the moon odyssey will enable India to upgrade technological expertise for exploration of outer space and ultimately help in setting up a base on the earth's natural satellite.
"Moon mission cost is less than Rs 400 crore, which is just ten per cent of annual budget of Isro spread over many years," Isro spokesperson S Satish said, countering critics who questioned the need for such a venture when other countries have already explored the moon.
Cost of India's first unmanned lunar mission, slated for October 22, is Rs 386 crore, which includes Rs 100 crore for the establishment of Indian Deep Space Network (IDSN) at Byalalu near here that will perform the task of receiving radio signals transmitted by future satellites, not just Chandrayaan-1.
"Those who argue that the moon mission is unnecessary do not know the full facts," say Isro officials.
For example, previous moon missions have been undertaken by individual countries and it's no secret that expertise of that nature are not shared. So, India had to do it by itself lest it would lose out in the race for the Moon. Besides, the moon mission would enable Isro to upgrade its technological expertise further as it takes steps towards its quest for exploration of outer space and inter-planetary missions.
"There is also the pride factor. With China forging ahead in the space field, India cannot lag behind and miss the bus. Moreover, some kind of colonisation of Moon cannot be ruled out in the coming decades. We have to have our presence," an Isro official told PTI.
