Decay Date: 1962-09-05 USAF Sat Cat: 34 COSPAR: 1960-Epsilon-1 Apogee: 514 km (319 mi) Perigee: 284 km (176 mi) Inclination: 65.0000 deg Period: 92.50 min The Soviet Union launched a Vostok 1KP prototype manned spacecraft (without heat shield; not recoverable) into near-earth orbit. On May 19, at 15:52 Moscow time, the spacecraft was commanded to retrofire. However the guidance system had oriented the spacecraft incorrectly and the TDU engine instead put the spacecraft into a higher orbit. Soviet scientists said that conditions in the cabin, which had separated from the remainder of the spacecraft, were normal. The program insignia shown above is post factum.
