In this lesson from Yale's Rocket Science for Everyone, astronomer Marla Geha explains Geosynchronous Earth Orbit, the distant orbital band where satellites match Earth's rotation and appear fixed over a single point on the ground. The lecture connects this property to practical applications such as continuous television broadcasting and real time weather monitoring. Following the course's earlier lessons on Low Earth Orbit and Medium Earth Orbit, this lecture completes the survey of the three major orbital regions, setting up the following lesson's direct comparison of all three in terms of altitude, speed, and use.
