... Because of the difficulties of working with and communicating with a satellite in low-earth orbit, and in order to make HST more efficient, virtually all actions taken by the spacecraft are planned weeks in advance. Only a small fraction of HST's time can be used for real-time actions that are at the discretion of the observer, and even then the only possible action is deciding which object in the field should be centered in the aperture before a subsequent observation is begun. ...
