Essay / Venus Probe Surface Exploration
Exploration of the surface of Venus is very difficult due to harsh atmospheric conditions and high temperatures. The surface temperature of Venus is between 450°C and 500°C. Therefore, if we design a space probe using conventional technologies, it will be destroyed above 200°C and we will not be able to obtain reliable results for our Venus exploration mission.

So our task now is to study the harsh environment as well as the operation of electronic devices in such an environment in order to introduce better materials or techniques that can contribute to the stable and reliable operation of such devices in the future. In 2017, NASA's Glenn Research Center introduced technology that can open new avenues for exploring Venus in the future. The words of NASA Senior Engineer Phil Neudeck are reproduced below. -duration of missions to the surface of Venus, “Venus belongs to one of the four terrestrial planets of the solar system and the second planet from the sun. Compared to other planets, it travels back and forth in a longer time and also in the opposite direction than many other planets. After the moon, it is the brightest object in the sky. The atmosphere of Venus is very stimulating and invites exploration of the surface. The atmospheric composition of Venus is approximately 96.5% CO2, 3.5% nitrogen, and traces of SO2, HCL, and HF. Compared to Earth, Venus' atmosphere is thicker and its nitrogen content is almost four times that of Earth. Our main goal is therefore to design a probe that will survive on the surface of Venus. We would therefore explore the state of the troposphere which extends from the surface to a radius of 65 km from the planet. The surface air density is 67 kg/m3 and the surface temperature is 740 K (467 °C). The pressure at the surface is 90 Earth atmospheres. We can imply that 99% of the atmosphere is within a radius of 28 km from the planet. There are also other factors that need to be defined, Venusian clouds which are composed of SO2 gas and H2SO4 droplets, the thickest layer of this cloud exists in the troposphere (~48 km). The strategy adopted to solve this problem is that, firstly, an in-depth study is carried out to observe the environment of Venus and the history of missions launched to explore Venus. Second, the list of problems that cause failure in the operation of the probe is extracted. Let's take a look at a brief history of early-era space probe failures. Venera 3 was the first spacecraft to crash into Venus in 1966. Venera 2 failed due to overheating shortly before the end of the mission. And it was the sister ship of the next version that landed successfully. After that, in 1967, Venera 4 managed to return measurements taken from the direct planet. Later in 1969, the results were verified by Venera 5 and Venera 6. In 1970, Venera 7 only managed to stay on the surface of Venus for 23 minutes due to intolerance to high temperatures. The main problem for solution seekers is only temperature.
