MARECS-B
1982-F06
The second MARECS was lost in the Ariane L5 launch failure. The third stage pump failed at an altitude of 182 km, 9 minutes after liftoff. Four minutes later the rocket and payload impacted the Atlantic 2700 km downrange from Kourou, off the coast of Africa.

Discoverer 2
1959-003
The second CORONA vehicle, Agena 1018, was intended as a recovery test, carrying a small biomedical payload. On rev 17 the CORONA was tilted down 60 deg for SRV ejection. The SRV ejected too early because of a programming error and landed somewhere near the Spitsbergen Islands in the Arctic. The SRV was probably the first artificial object to return intact to the Earth from orbit. It may even have been the first to be recovered - although the CIA never saw it again, they concluded at the time that the Soviets may have located it, inspiring the novel and movie `Ice Station Zebra'. However, the Soviet involvement seems to have been an imaginative stretch.

Jikiken
1978-087A
The EXOS-B spacecraft, Jikiken (Magnetosphere), was launched on 1978 Sep 16 by Mu 3H. It had four long antennae to study magnetospheric fields.
The 92 kg satellite was a domed polyhedral cylinder, 0.75m dia 0.60m high of a different design to the Tansei-3/EXOS-A satellites. EXOS-B had a new, 0.70m dia KM-B kick motor as a fourth stage. Unlike MS-T3, the motor was below the payload at launch and was fired immediately after the third stage, which was suborbital. 30 min later NASA picked up the signal. The antennae were extended, dropping spin rate from 150 to 3 rpm. Actual deployment was to 69.8m and 103.0m span (maximum would have been 206 m span).
KM-B mass is 284 kg f 49? em, 22.6 kN, 0.86m long 0.73m dia, Isp 283s, 30 s burn time. The delta-V calculations suggest a stage 3 orbit of -1000 x 231 km but the impact zone of 160W 10N suggests a trajectory more like -450 x 231 km.
