You may find the European Space Agency's specifications more elegantly organized and easier to understand than NASA SPEC. The ESA spec includes nearly all the details of the NASA and applicable U.S. military specs, but benefits from being able to take a fresh look at how to organize and present the data.
The primary drawbacks to the ESA specs are their devotion to (and inconsistent use of) the French system of units and some rough spots where the authors seem to emphasize style over utility. So as always when working with specifications and especially with the metric system, be careful.
See notes at the bottom of this page for information on how to acquire copies of these documents. They are generally published as bound pamphlets on standard metric paper at a price of 10 euros each.
