DISCOVERE 34, also known as CORONA 9027, was a United States optical reconnaissance satellite which was launched on 5 November 1961.

[1] Although the satellite achieved orbit, and was assigned the Harvard designation 1961 Alpha Epsilon 1, the launch was unsuccessful.

[2] The satellite had a mass of 1,150 kg (2,540 lb),[5] and was equipped with a panoramic camera with a focal length of 61 cm (24 in), which had a maximum resolution of 7.6 m (25 ft).

[6] Images were to have been recorded onto 70 mm (2.8 in) film, and returned in a Satellite Recovery Vehicle (SRV).

Due to the launch failure, and a problem with a gas valve on the spacecraft, recovery of the SRV was not attempted.
