Google Earth does not feature a live satellite feed. There are a handful of start-up companies attempting to create such a feature, but they remain limited in their scope and frequency. A company called Sky-Sat1 is working on such a service and has two satellites in operation.
One possible alternative to a live satellite feed is viewing footage filmed by the International Space Station. The station completes a rotation of the Earth every 90 minutes. It is possible to watch a high-definition stream of an external camera as it passes over the planet. The angle is different from the traditional Google Earth view but still captures a broad geographic range.
