Corona 75
1963-055A
The final KH-4 flight, M-26, was mission 9062. It was launched by a Thrust Augmented Thor Agena D from Vandenberg on 1963 Dec 21, and inserted a P-11 class subsatellite into orbit. The SRV was recovered in mid-air over the Pacific on Dec 26 after a 5 day flight, but once again corona static marred much of the film. The CIA technical representative had refused to approve M-26 for flight until incorrectly performed preflight environmental testing was repeated, but was overruled by the USAF (NRO Program A) manager, exacerbating the political mess between USAF and NRO. Nevertheless, much data was useable and it observed an ICBM site, a nuclear weapons bunker, rocket engine test facilities, and surface-to-air missile sites.
The NPIC PER (COR-2458) refers to the mission as Discoverer 74, the latest reference in an offical document to a Discoverer sequence number, and probably an error (it was removed in the longer alternate version of the same PER available in the National Archives).

Prospero
1971-093A
The final Black Arrow launch from Woomera Site 5B, R-3, left the pad on 1971 Oct 28 carrying the X-3 technology satellite. X-3 was built and operated by the UK Royal Aircraft Establishment at Farnborough in Hampshire. X-3 and the Waxwing final stage motor reached polar orbit successfully. The 66 kg, 1.1m dia 0.71m high satellite was named Prospero. Prospero was still working in 1989 when the ground station at Lasham was closed down.
R-3 ussed Gamma 8 No 7 and Gamma 2 No 6.
Waxwing was 315 kg of prop at 156 kN. Dry mass was 35 kg; a 14 kg separation adapter was also orbited attached to Waxwing. One of Prospero's 0.5m aerials is believed to have been broken off shortly after separation.
