The NASA administrator has said, according to USA today that the Space Shuttle and the ISS were "mistakes".
Well, that makes me feel good to know I spent 15 years working on "mistakes". I knew we should have been going to the moon and Mars a long time ago. Nice of them to figure it out after all this time. But to call the entire manned program for the last 30 plus years a mistake? Gee. "Sorry NASA employees and contractors, your entire careers have been wasted on a mistake. Have a nice day."
