The launch of Discoverer 34 occurred at 20:00 UTC on 5 November 1961. A Thor DM-21 Agena-B rocket was used, flying from Launch Complex 75-1-1 at the Vandenberg Air Force Base. Although the satellite achieved orbit, and was assigned the Harvard designation 1961 Alpha Epsilon 1, the launch was unsuccessful. An anomalous angle taken during ascent resulted in the spacecraft being placed into an unusable orbit. It was the second consecutive KH-3 launch failure; the previous mission, Discoverer 33, had failed to achieve orbit due to a separation failure.

abstract
  • The launch of Discoverer 34 occurred at 20:00 UTC on 5 November 1961. A Thor DM-21 Agena-B rocket was used, flying from Launch Complex 75-1-1 at the Vandenberg Air Force Base. Although the satellite achieved orbit, and was assigned the Harvard designation 1961 Alpha Epsilon 1, the launch was unsuccessful. An anomalous angle taken during ascent resulted in the spacecraft being placed into an unusable orbit. It was the second consecutive KH-3 launch failure; the previous mission, Discoverer 33, had failed to achieve orbit due to a separation failure. Discoverer 34 was launched into a low Earth orbit, with a perigee of kilometre (mi), an apogee of kilometre (mi), 82.5 degrees of inclination, and a period of 96.6 minutes. The satellite had a mass of kilogram (lb), and was equipped with a panoramic camera with a focal length of centimetre (in), which had a maximum resolution of metre (ft). Images were to have been recorded onto -millimeter () film, and returned in a Satellite Recovery Vehicle. The Satellite Recovery Vehicle to be used by Discoverer 34 was SRV-553. Due to the launch failure, and a problem with a gas valve on the spacecraft, recovery of the SRV was not attempted. Discoverer 34 decayed from orbit on 7 December 1962.
