FTV-1126, also known as Corona 9034A, was an American area survey optical reconnaissance satellite launched in 1962. It was a KH-5 Argon satellite, based on an Agena-B. [1] It was also unofficially known as Discoverer 41, a continuation of the designation sequence used for previous US reconnaissance satellites, which had officially been discontinued after Discoverer 38. It was the first KH-5 satellite to complete its mission successfully. [2]
The launch of FTV-1126 occurred at 19:36 UTC on 15 May 1962. A Thor DM-21 Agena-B rocket was used, flying from Launch Complex 75-3-5 at the Vandenberg Air Force Base. [3] Upon successfully reaching orbit, it was assigned the Harvard designation 1962 Sigma 1.
FTV-1126 was operated in a low Earth orbit, with a perigee of 284 kilometres (176 mi), an apogee of 632 kilometres (393 mi), 82.3 degrees of inclination, and a period of 93.75 minutes. [4] The satellite had a mass of 1,150 kilograms (2,540 lb), [2] and was equipped with a frame camera with a focal length of 76 millimetres (3.0 in), which had a maximum resolution of 140 metres (460 ft). [5] Images were recorded onto 127-millimeter (5.0 in) film, and returned in a Satellite Recovery Vehicle, before the satellite ceased operations. The Satellite Recovery Vehicle used by FTV-1126 was 582. Once its images had been returned, the inactive FTV-1126 decayed from orbit on 26 November 1963. [4]
Discoverer 30, also known as Corona 9022, was an American optical reconnaissance satellite which was launched in 1961. It was a KH-3 Corona''' satellite, based on an Agena-B rocket.
Discoverer 25, also known as Corona 9017, was an American optical reconnaissance satellite which was launched in 1961. It was the fifth of ten Corona KH-2 satellites, based on the Agena-B.
FTV-2203, also known as Samos 5, was an American reconnaissance satellite launched in 1961 as part of the Samos programme. It was a film return reconnaissance spacecraft, meaning that it returned images in a film capsule at the end of its mission. FTV-2203 was a Samos-E5 spacecraft, based on the Agena-B. It carried a camera with a focal length of 1.67 metres and a resolution of 1.5 metres.
Discoverer 23, also known as KH-5 9016A, was a USAF photographic reconnaissance satellite under the supervision of the National Reconnaissance Office (NRO) which was launched in 1961. It was a KH-5 ARGON satellite, based on an Agena-B. It was the second KH-5 mission to be launched, and the second to end in failure.
Discoverer 24, also known as Corona 9018A, was an American area survey optical reconnaissance satellite which was launched in 1961 but failed to achieve orbit. It was a KH-5 Argon satellite, based on an Agena-B. It was the third KH-5 to be launched.
Discoverer 27, also known as Corona 9020A, was an American area survey optical reconnaissance satellite launched in 1961, but which failed to achieve orbit. It was a KH-5 Argon satellite, based on an Agena-B. It was the fourth KH-5 to be launched, the second consecutive KH-5 launch failure, and the fourth consecutive KH-5 mission failure.
FTV-1132, also known as the Corona 9042A, was an American area survey optical reconnaissance satellite which was launched in 1962. It was a KH-5 Argon satellite, based on an Agena-B. The satellite operated successfully, but its film capsule was lost during recovery due to a parachute failure.
Discoverer 22, also known as Corona 9015, was an American optical reconnaissance satellite which was lost in a launch failure in 1961. It was the fourth of ten Corona KH-2 satellites, based on the Agena-B.
Discoverer 26, also known as Corona 9019, was an American optical reconnaissance satellite which was launched in 1961. It was the sixth of ten Corona KH-2 satellites, based on the Agena-B.
Discoverer 28, also known as Corona 9021, was an American optical reconnaissance satellite which was lost in a launch failure in 1961. It was the seventh of ten Corona KH-2 satellites, based on the Agena-B.
Discoverer 16, also known as Corona 9011, was an American optical reconnaissance satellite which was lost in a launch failure on 26 October 1960. It was the first of ten Corona KH-2 satellites, based on the Agena-B.
Discoverer 17, also known as Corona 9012, was an American optical reconnaissance satellite launched on 12 November 1960 at 20:38:00 GMT. It was the second of ten Corona KH-2 satellites, based on the Agena-B.
Discoverer 29, also known as Corona 9023, was an American optical reconnaissance satellite which was launched in 1961. It was the first KH-3 Corona''' satellite, which was based on an Agena-B rocket.
