Re: India conquer Martian space!!!
I did not say manned mission to bring samples back. I said that we dont have that capability (mainly financial, but also technological) to build a round trip from a planet, whether its manned or unmanned. We can build a flyby round trip mission very cost effectively, but one that needs to land and collect sample and then fly back to earth is out of reach for now.
And about the sun, you can do flyby, or orbital, but it has to be outside the 4 million miles from sun. But no, you can not make a matter that could survive sun’s crushing forces. If heat could not kill it, Sun’s high gravitational force would flatten the object in seconds. Sun’s gravity is 28 times more than earth, so an object would crush under its own weight on sun
