At least once you are saying something that makes senss.
The mars mission has no cost benfits in return, while the capability to launch sats far cheaper than western competitors is a huge advantage for India and results in a profitable business and that's nothing new either, we are doing this for quiet some time now. We had some setbacks, but the cost-benefits still makes ISRO very attractive in this field. So while the one is a project that only costs India money, the other is far more beneficiary and that's what the Indian space program should be focused on. Benefits for Indian people and Indian industrial capabilities, not on prestige projects.
