Interkosmos 1

 1969-088A

---

The first DS-U3-IK satellite was launched on 1969 Oct 14 by the 11K63 Kosmos launch vehicle from GTsP4 (Kapustin Yar). It was given the code name Interkosmos-1. Interkosmos-1 carried solar monitors built in the USSR, the GDR and Czechoslovakia. UV and X-ray detectors observed the sun directly, while an optical photometer looked at the setting or rising sun through the Earth's atmosphere to detect absorption by atmospheric aerosols.

Size 2.64 long 2.88 dia. Mass 303 kg with 38 kg instruments.

Kosmos 206

Meteor No. 10 was launched in Mar 1968 and its mission was successful. The Blok-E stage burned a little longer than usual but this doesn’t seem to have seriously affected the mission.

Kosmos 548

 1973-008A

---

A Zenit-4M (11F691) mission was launched in Feb 1973 from Plesetsk. Kosmos-548 stayed in orbit for 13 days. Object D, jettisoned in low orbit on Feb 20, is probably the engine; objects E and F in higher apogees may be retro motor covers, although RAE labels F as the engine.
