SpaceX is launching a Falcon 9 on February 17 (should the current target date stick) and the rocket is carrying a primary payload of a Spanish satellite for client Paz. The secondary cargo on the launch is more interesting, however, since it’s two of SpaceX’s own satellites – demonstration satellites the company is putting into orbit to test its plan to offer satellite-based broadband internet communications services.

The rocket will include Microsat-2A and Microsat-2B (via TheNextWeb), small satellites with a planned useful lifetime of just 20 months. Both will contain Ku-band broadband transmitter radios, allowing them to test their ability to offer Earth-based connectivity from low-Earth orbit.
