Jeff Foust has taken some pictures of the new annex to the National Air and Space Museum out by Dulles Airport. There are also interesting articles at today’s The Space Review by Sam Dinkin, about the prospects for O’Neillian space colonies (with a little historical perspective of the concept), and by Stephen Ashworth on the vital need for NASA to work cooperatively, rather than adversarially, with private enterprise. Finally, Jim Oberg has a first-hand account of how technical organizations become sloppy, with potentially deadly consequences.
