Kosmos 573

Cosmos 573 is the codename for an unmanned flight of the Soviet Soyuz spacecraft, which carried out 1973 tests in Earth orbit in the summer. It was common in the Soviet Union to give only successful missions an official name. Failed flights were mostly not announced and test flights only under the general cover name cosmos.

The flight

The launch took place on June 15, 1973 at 6 UTC clock from Soviet Baikonur Cosmodrome aboard a Soyuz rocket.
