The Indian Space Research Organisation (ISRO) spent just over Rs 380 crore (about half the price of a Jumbo Jet) on Chandrayaan-1, with 1,000 scientists toiling over it for three years. A similar effort by NASA or any other space agency would have cost at least five times more. In real terms, Chandrayaan-1 cost only about 4% of Isro’s budget over three years.

Chandrayaan-2 is expected to cost ISRO just Rs 500 crore. Isro’s annual budget only recently increased to Rs 5,000 crore or $ 1 billion. This happened when the Mark 3 of GSLV was commissioned and there was a new thrust towards societal application of space projects. Five years ago, Isro’s annual budget was merely around just $200 million
On the brighter side, Antrix Corporation, Isro’s commercial wing, has earned Rs 900 crore from commercial satellite launches and sale of remote sensing data last financial year and the revenues are growing at 25%. “We have launched 16 satellites for other countries so far and another four are on the anvil. Commercial launches add to our earnings,” says Madhavan Nair. This should augur well for Isro, which has such ambitious projects as the Rs 12,000 crore manned space mission scheduled for 2015
