What follows is a discussion of the methods used to identify the satellite as LES-5 and determination that the telemetry transmissions may have scientific value as if the spacecraft is sending meaningful telemetry, researchers may be able to obtain valuable information on how hardware launched into a high Earth orbit 53 years ago has faired.
