That's $20,000,000,000.
Last time that a major amount of money was spent mankind was going to the Moon.
Don't get me wrong: That was real great ! I'm a big fan of that undertaking. But I don't wonna do it just once.
The fact that it must have been a tremendous sum turned out in 1972 when the public learned that there would be no more flights to the moon. Wars on earth seemed to be more important so that no more public money was available for the peaceful progress of mankind.
Some people take the view that private industry nowadays can do it better anyway and cheaper, too. I'd support that opinion.
I think we should have learned from the big regress concerning manned space travel after the sudden death of the manned moon travel program.
Shall we leave it up to our children to see the other planets of our solar system ? Shall we just leave it up to a few astronauts/cosmonauts/taikonauts to go there ?
I must confess: I'm more selfish.
I wonna have it myself - and I wonna have it now.
