Vesmírný samožer

Opravdu zajímavý pohled na raketoplány a mezinárodní vesmírnou stanici (ISS):

The final Shuttle design, incorporating all of the budgetary and Air Force design constraints, was impressive but not particularly useful. Very soon after the start of the program, it became clear that Shuttle launches would not be routine events, that it would cost a great deal of money to repair each orbiter after its trip to space, and that estimates of launch cost and frequency had been wildly optimistic. At the same time, the Air Force proved unable to get the Vandenberg base ready for use, negating much of the reason for the extensive Shuttle redesign. After the Challenger explosion, the Vandenberg base was quietly mothballed. Not once did the Shuttle fly a mission to polar orbit.
In the thirty years since the last Moon flight, we have succeeded in creating a perfectly self-contained manned space program, in which the Shuttle goes up to save the Space Station (undermanned, incomplete, breaking down, filled with garbage, and dropping at a hundred meters per day), and the Space Station offers the Shuttle a mission and a destination. The Columbia accident has added a beautiful finishing symmetry - the Shuttle is now required to fly to the ISS, which will serve as an inspection station for the fragile thermal tiles, and a lifeboat in case something goes seriously wrong.

This closed cycle is so perfect that the last NASA administrator even cancelled the only mission in which there was a compelling need for a manned space flight - the Hubble telescope repair and upgrade - on the grounds that it would be too dangerous to fly the Shuttle away from the ISS, thereby detaching the program from its last connection to reason and leaving it free to float off into its current absurdist theater of backflips, gap fillers, Canadarms and heroic expeditions to the bottom of the spacecraft.
