Intelsat II F-1, also known as Blue Bird was a communications satellite operated by Intelsat. Launched in 1966 it was intended for operations in geostationary orbit over the Pacific Ocean to provide a communications link between Australia and the United States, however a malfunction prevented the satellite from reaching its planned orbit.
The first of four
Hughes Aircraft around the HS-303A satellite bus. It carried two transponders, which were powered by body-mounted solar cells generating 85 watts of power.[1]
Intelsat II F-1 was launched atop a
apogee motor, which was to be fired to raise the spacecraft into its operational geostationary orbit, however this failed four seconds after ignition. The spacecraft was left in its transfer orbit, unable to complete its primary mission, however it was used for some tests and limited communications.[4]
Intelsat II F-1 remains in orbit.[5] As of 2 May 2023 it was in an orbit with a perigee of 3,265 kilometers (2,029 mi), an apogee of 37,121 kilometers (23,066 mi), inclination of 17.70 degrees and an orbital period of 11.97 hours.[3]
