  No but he set out on an expensive and high-risk endeavor. It was hoped to be profitable, but was a money sink until proven otherwise.

    Not remotely in the same scale, considering the time, development and resources that go into conducting even the first manned mars mission. Putting people on Mars to save humanity is - in my view - a bad reason. There are better reasons to travel to mars.

      He didn't have to design the Caravel, no. He had that at his dispose, but it's not like that all came from nothing. It took time to build and develop as well.
