SpaceX's Secondary Payload, the Orbcomm satellite falls from orbit

As mentioned in a previous post, the Orbcomm satellite, which was a secondary payload on SpaceX's CRS-1 mission, failed to be placed into a good orbit because of the failure of the Falcon 9's number 1 engine.  While the failure did not impact the primary mission, as the Falcon 9 is able to achieve orbit with up to 2 engine failures, the failure prevented a secondary burn of the second stage required to deliver the Orbcomm satellite into the required orbit.

At the time Orbcomm was working with the satellite manufacturer to determine if the satellite's thrusters could be used to obtain a more stable orbit, but news today reports the satellite has lost orbit.  Despite the failure, usefull data has been obtained, which allowed Orbcomm to validate the satellite and clear the way for the launch of the entire constellation of satellites - for which SpaceX is the contracted launch provider.

Additionally, Orbcomm understood that the satellite was not the primary mission, and there was a possibility that the orbit rising second burn may not be able to be performed if it was in conflict with the primary mission.  NASA agreed to the secondary mission, but with strict parameters, which could not be met after the engine misshap.
