Questions about Venera 4
Short answers, pulled from the story.
How long did Venera 4 transmit data before signal termination?
The descent lasted exactly 93 minutes before signal transmission terminated. The capsule deployed its parachute at an altitude of about 50 kilometers above the surface and started sending data immediately.
What atmospheric composition did Venera 4 measure for Venus?
Measurements revealed 90 to 93 percent carbon dioxide with small amounts of nitrogen and oxygen. Oxygen levels ranged from 0.4 to 0.8 percent while nitrogen made up 7 percent.
Why did Venera 4 fail to reach the surface of Venus?
The probe disintegrated during entry into the Venusian atmosphere near the equator on the 18th of October 1967. A liquid-fuel thruster resided in the rear part of the carrier spacecraft to correct the flight course if needed but could not prevent the station from releasing the landing capsule and then disintegrating.
What temperature did Venera 4 record at 24 kilometers altitude?
Scientists recorded a temperature of 24 degrees Celsius at an altitude of 24 kilometers. Pressure readings showed less than 10 atmospheres at that height.
