Sadly, I feel they should. Pure research is not enough justification for the billions that they need every year nowadays, and frankly, the US can no longer afford it.
If the science behind the development of space travel is to progress it has to become affordable, and that can only happen if the private sector becomes involved.
In my view...
Dear Buzz Gang and Crew,
NASA the "National Aeronautics and Space Administration", is in another budget battle with the U.S. Congress. Now NASA is considering working together with commercial organizations and companies to continue space craft launches. Should NASA be a "For Profit" Enterprise? I am really torn by this because there is value in "pure research".
