Cosmos 373



Cosmos 373 was initially placed in an eccentric orbit where it abandoned its carrier rocket. The main payload maneuvered downward into a lower circular orbit. Afew days later, Cosmos 374 maneuvered from an initial orbit very similar to the initial orbit of Cosmos 373 to a higher eccentric orbit. British measurements show that Cosmos 374 passed close to Cosmos 373 at perigee. On moving away, Cosmos 374 was exploded into many pieces of debris. A week later, Cosmos 375 repeated most of the maneuvers of Cosmos 374.
