MIK-2: preparation of Sputnik-4

During 1960 and 1961, in preparing for the manned phase of the Vostok program, the Soviet Union launched a series of satellites under the name "Korabl-Sputnik".
A 287t Vostok rocket orbited the Vostok prototype, which carried two solar panels mounted on a boom at front. The primary sensor for the 'Altitude Control System' used an infra-red scanner, which gave trouble, but controlers decided to rely on this anyway, rather than the back-up sun-sensor.
On 19 May, during orbit 64, the retro-rocket fired and the craft climbed up to a 190-428ml orbit because it was orientated wrongly. The cabin, which had no heat-shield, then separated; it fell back in Oct. 1965. The intention had been for it to burn up on re-entry. It was decided to fit primary solar and manual back-up orientation systems to the Mk.III manned version. Subsequent KS flights used the Mk.I; Mk.II was the Zenit spy-satellite.
