Explorer 12

  1961-020

---

The S-003 payload, also known as EPE-A (Energetic Particles Explorer A), was launched on 1961 Aug 15 by Delta from Cape Canaveral into a highly elliptical orbit with an apogee of 77000 km. Interestingly, it was the first satellite to be launched into an orbit with a period close to the geosynchronous period of 24 hours. Explorer XII transmitted until 1961 Dec 6 and reentered on 1963 Sep 27.

Mass was 38 kg. Size was 0.48m high 0.66m dia with a 0.81m magnetometer boom.

The prelaunch plan was a first perigee at 14N 49W and apogee at 12S 99W.

OTS 2 was launched aboard a Delta 3914. The spacecraft carried out tests of television direct broadcasting, oil platform communications, and newspaper data transfer. ESOC controlled the apogee firing. OTS was built by BAe Dynamics (formerly HSD)

Hexagon 20

 1986-F03

---

The final KH-9 spacecraft, number 20 in the series, was launched on 1986 Apr 18. Only 8 seconds after launch, separation of insulation material in the Titan SRM 122 led to a burnthrough followed by a spectacular explosion 200 meters above Space Launch Complex 4-East. The SRM broke free of the stack, and some of the destruct system failed to work; a large chunk of the motor fell to the ground and exploded. The launch vehicle and spacecraft were completely destroyed, with serious damage to pads SLC4E and SLC4W. Following the loss of a KH-11 on the previous Titan launch and the loss of the space shuttle Challenger soon afterward, the NRO space program faced a crisis.
