This is where the Shuttle and ISS conduct their operations. One complete orbit in LEO takes about 90 minutes. Satellites that seem to be attached to some location on Earth are in Geosynchronous Earth Orbit (GEO). These satellites orbit about 23,000 miles above the equator and complete one revolution around the Earth precisely every 24 hours. Satellites headed for GEO first go to an elliptical orbit with an apogee about 23,000 miles.
