Hey Congress, go tell NASA to find "private donors" for this project.
With the money the taxpayers have spent on space exploration so far, we could have a nationwide mass transit system, an incredibly advanced military ( more so than it is now ), and New Orleans wouldn`t be flooded right now.
If private business invested in space exploration all these years, I would believe there would be people on the moon right now,.... on vacation.
