Detailed explanation-1: -Venera 7 was one of two identical spacecraft launched to Venus during the August 1970 opportunity. The other mission (Cosmos 359) failed to leave Earth orbit. The objectives of the missions were to return data from the Venus atmosphere, make a landing on the surface, and continue to return data after landing.
Detailed explanation-2: -So what did Venera 7 say from the surface of Venus? The probe was able to send data on the temperature of Venus (a mind-boggling 887 degrees Fahrenheit or 475 degrees Celsius), the atmospheric pressure (92 bar) and a wind speed of 2.5 meters per second (nearly 5.6 mph or 9 km/h).
Detailed explanation-3: -However, Venera 7 was successful and was the first designed for a soft’ landing on Venus. The journey took 120 days, and the probe arrived with all its equipment working.
