Mr Venkatesh Prabhu, You have put all these years of Research and Development of the space sciences in question by the way you commented about NASA! You must be aware of the facts before you make any comments on an ace organisation. Also, lets not compare ISRO and NASA. Both their missions and goals are not same. NASA is a bigshot organization in terms of its budget, reach, age and 'resources'. Kudos to all the scientists and people who made all these space explorations possible.
