Mars 2MV-1 Chronology
25 August 1962
Sputnik 19 Program: Venera. Launch Site: Baikonur . Launch Vehicle: Molniya 8K78. FAILURE: At T+60 min 50 sec one of the four solid motors of the escape stage's BOZ unit did not fire. The resulting asymmetric torque caused the stage to lose correct attitude and three seconds after ignition of the main engine S1.5400A1 it began to tumble. Mass: 890 kg. Perigee: 173 km. Apogee: 252 km. Inclination: 64.9 deg.
The motor burnt for only 45s of the planned 240s. The stage remained in Earth orbit.
