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.
