Venera-7

[p]The first spacecraft to successfully land on the surface of Venus is 55 years old! ⭐[/p][p][/p][p]The Venera-7 station is a real breakthrough in space exploration. After working for 20 minutes on the surface of the most ferocious🔥 and deadly☣ planet in the Solar System, the device transmitted valuable data on the temperature of the atmosphere and surface, as well as pressure data.[/p][p]The body of the device was made of titanium📏, replacing the aluminum alloy of earlier versions of the Venus series devices. This allowed him to stay so long at a temperature of 450°C and a pressure of 100 atmospheres! Plus, an interesting ❄cooling scheme was applied - before entering the atmosphere, the lander was deeply cooled to -8°C using an external refrigeration unit. The device itself did not have its own "refrigerator" — its role was performed by the large heat capacity of the all pre-frozen titanium structure. Like a huge thermal accumulator, it slowly "absorbed" the Venus heat, which allowed the electronics to work for additional precious minutes after landing.[/p][p]By the way, someday I will add a small base to the game on the planet Venus, there is evidence that it is a little "cooler" at mountain heights, and atmospheric pressure here is not so much "pressing".[/p]
