1960-005
The prototype Vostok spaceship, Vostok-1P (Article 1KP), was launched in May 1960. The launching was announced as the first Korabl'-Sputnik (Spaceship-Satellite), and in the West it was nicknamed Sputnik 4. Vostok-1P was intended to test the basic attitude control systems and the retrorocket, but it did not have a heat shield and it was not intended to survive reentry.
After 4 days in orbit its retrorocket fired in the wrong direction, and both the descent module (Spuskaemiy Apparat) and the service module (Priborniy Otsek) were left in an elliptical orbit together with seven fragments. The PO reentered in 1962 and the SA in 1965.
