- jgrahamc 14y agoRocket launch time is largely determined by the eventual orbit: http://en.wikipedia.org/wiki/Launch_window http://en.wikipedia.org/wiki/Launch_window
- smithian 14y agoISS bound launches have to launch while the ISS is passing overhead so that the orbit of the spacecraft is at the same inclination as ISS. The reason for this is that inclination changes are expensive fuel-wise once you're in orbit.
