Aug 21, 2015 at 22:27 comment added user3652621 Ah, the concept for space launch ideally has a skyhook connecting at fixed intervals of time to the end of a space elevator in geostationary orbit, so the skyhook benefits from the terrestrial rotation indirectly.
Aug 21, 2015 at 22:26 comment added Samuel @SerbanTanasa Skyhooks are not connected to the Earth. A ship would still need to launch from Earth to get there.
Aug 21, 2015 at 22:25 comment added user3652621 You mean skyhooks?
