Mars 2MV-1 Chronology
  • 1962 August 25 - Sputnik 19 - Program: Venera, Vostok. Launch Site: Baikonur. Launch Complex: LC1. Launch Vehicle: Soyuz. 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 (1,960 lb). Perigee: 173 km (107 mi). Apogee: 252 km (156 mi). Inclination: 64.90 deg. Period: 88.70 min.
    Attempt to launch a probe towards Mars. The launch went well, but the fourth stage motor burnt for only 45s of the planned 240s. The stage remained in Earth orbit. However Kamanin notes that it was good that the launch of the basic vehicle was a success - it gave the visiting female cosmonauts confidence in the rocket they will have to ride.

  • 1962 September 1 - Sputnik 20 - Program: Venera. Launch Site: Baikonur. Launch Complex: LC1. Launch Vehicle: Soyuz. FAILURE: At T+ 61 min 30 sec the fuel valve did not open.; the ignition command was blocked from going to the main engine of Stage 4. Mass: 6,500 kg (14,300 lb). Perigee: 185 km (114 mi). Apogee: 246 km (152 mi). Inclination: 64.70 deg. Period: 88.80 min.
