Very good synopsis and detailed precisely. Good references, please give more. Cheers --88.103.1.179 (talk) 23:47, 1 December 2008 (UTC)[reply]

Why wait until after take-off?[edit]

Q. Why wasn't the shuttle simply put onto the pad in the right direction, so that no roll would be required? -- A. Because the in-flight roll is relatively trivial compared to the rotation of the huge launch pad. Plus, the desired orientation is dependent on time of launch. If there is a launch delay, the in-flight roll can be easily adjusted, whereas the need to re-orient the launch pad would basically scrub the launch.

Is the pad built in such a way that the shuttle has to be oriented in the same way for each launch?--Avl (talk) 11:19, 23 March 2012 (UTC)[reply]

Answering my own question: Putting the Shuttle in any other orientation on the pad would require the crawler to rotate, which would either stress the ground track severly if done in place, or take a lot of time if the crawler was sent on a big loop to accomplish the turn. Also, the rolling in flight isn't a problem.Avl (talk) 18:00, 8 August 2012 (UTC)[reply]

Other rockets?[edit]

Doesn't just about everything use this? See Mercury-Atlas 3 and Polar Satellite Launch Vehicle, for example. Bubba73 ^{You talkin' to me?} 07:03, 6 February 2015 (UTC)[reply]

Isn't the section about the space shuttle just shit?[edit]

For example, how does orienting the space shuttle in the correct direction to meet its target orbit achieve these things listed in the article?:

Increasing the mass that can be carried into orbit
Increasing the orbital altitude
