  1970-011A

The fifth orbital attempt by ISAS was at last successful. The L-4S-5 final stage entered orbit with a small instrument package attached to it; it was given the name Osumi after a local district. The 24 kg satellite transmitted for 16 hrs.

11F91 No. 4 was launched on 1967 Sep 27 but the Proton-K first stage failed. The descent module was recovered using the launch escape system, landing 65 km north of Baikonur. This vehicle would have been the first circumlunar attempt of the Zond program.

Kosmos 496

  1972-045A

A year after the Soyuz-11 tragedy, a modified spacecraft, 11F615A8 No. 33A (A for automatic), was launched on a mission to test out changes made in the wake of the accident. It was given the cover name Kosmos-496. The six day flight seems to have been successful.
