[2] The probe's intended purpose was to explore Venus, but an error caused the final-stage rocket to malfunction.
[5] The lander was designed to be able to survive atmospheric pressures of up to 180 bars (18,000 kPa) and temperatures of 580 °C (1,076 °F).
[6] This was significantly greater than what was expected to be encountered, but significant uncertainties as to the surface temperatures and pressure of Venus resulted in the designers opting for a large margin of error.
[6] After reaching orbit, the main upper stage engine ignited late and shut down early after running for only twenty-five seconds.
[5] Kosmos 359 carried a limited set of scientific instruments, including a solar wind detector, cosmic-ray detector, resistance thermometer, and aneroid barometer.
