If you combine the populations of India and China, isn't it something like seven times the population of the United States? Yet, we're having more of an effect on their culture than they are having on us. What does that tell you, friend?
I'm no astrophysicist or aeronautical engineer, but it seems to me that at least 99.9% of any space vehicle's journey to any other planet in our star system is going to be uneventful and easy to manage; it's the end of the journey that's going to pose possible difficulties. The paper ball you toss at the trash can flies through the air uneventfully -- but whether or not you get it in the can, have it bounce off the rim, or miss the can entirely at the end of it's flight is something else entirely.
Not that I'm trash-talking Indian engineering or scientific ability. I work with enough Indian engineers to know better than that. Now if they could just learn to solder worth a damn. XD
