OKB-1

Mars 1M No.2 (Korabl 5)

The Soviet probe Korabl 5 (1M No. 2) was destroyed on October 14, 1960, during its launch to Mars after a catastrophic third-stage (Block I) failure at T+290 seconds. A liquid oxygen leak froze the kerosene in the turbopump, preventing ignition and forcing a suborbital re-entry over Siberia.

Korabl 4 (Mars 1M No. 1)

Korabl 4, launched by the Soviet Union in October 1960, was the first probe designed to perform a flyby of Mars. The mission failed during its ascent phase due to vibration and resonance issues in the upper stages of the launch vehicle, preventing it from reaching Earth orbit.
