What did Venera 4 discover?
It detected a very weak atmosphere of atomic hydrogen about 6,150 miles (9,900 kilometers) above the planet. Noteworthy was Venera 4’s detection of the planet’s bow shock, identified a day before by Mariner 5 (and later confirmed by Venera 5). The mission’s importance was underscored when NASA Administrator James E.

What did Venera 7 discover?
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).
Has any probe landed on Venus?
On December 15, 1970 an unmanned Soviet spacecraft, Venera 7, became the first spacecraft to land on another planet. It measured the temperature of the atmosphere on Venus.
