From: Tom Wadlow <TAW@S1-A> One major factor is that NASA always tries to deploy a satellite in full daylight. That, plus a minimum fuel boost to the right slot in geosynch and a (usually futile, I suspect) try at getting the deployment to happen when the shuttle can talk to the ground (not very often, just yet) add up to a fairly small set of launch windows. --Tom
