Kosmos 212

  1968-029A

---

7K-OK No. 8 (Kosmos-212) was launched in Apr 1968 as the active chase craft in a docking pair. Just before the launch of its partner, problems with the roll control engines were discovered but the decision was made to proceed with the second launch anyway.

Kosmos-212 made rendezvous the next day with the passive 7K-OK No. 7 and docked with it automatically using the Igla system, repeating the success of Kosmos-186. 14 engine burns were required, compared to 28 on the previous flight. The two spacecraft remained docked for a few hours; Kosmos-212 remained in orbit for tests for five more days.
