1963-001B
The first E-6 was E-6 No. 2 (No. 1 was a ground test article). It was launched on 1963 Jan 4. It used the first 8K78L rocket, a version of the 8K78 whose upper two stages were guided by a control system on the E-6 payload. It reached orbit, but the Blok-L stage did not ignite. The BOZ ullage unit failed to operate because of a power system failure and the I-100 control unit on the E-6 failed to send the ignition command to the Blok-L. Three objects were tracked; object 01A (SATCAT 521) is thought to have been the Blok-I stage, and reentered in a day. Object 01B (SATCAT 522) is usually listed as the E-6 probe with object 01C as debris; however 01C seems to have decayed more slowly. An alternate possibility is that 01C was the E-6 and Blok-L (still attached) while 01B was the BOZ unit.
