Topic > Exploration of the surface of the Venus probe

Exploration of the surface of Venus is very challenging due to harsh atmospheric conditions and high temperature. 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.

Many attempts have been made to explore Venus over the last two centuries but unfortunately they have never achieved much success. So, our task now is to study the harsh environment and also the operation of electronic devices in that environment to introduce better materials or techniques that can help the stable and reliable operation of that kind of devices in the future. In 2017, NASA's Glenn Research Center introduced technology that may open new avenues for the exploration of Venus in the future. The words of Phil Neudeck, NASA lead engineer are reported below. “With further development of the technology, such electronics could dramatically improve Venus lander designs and mission concepts, enabling the first long-duration missions to the surface of Venus,” Venus is from one of the four terrestrial planets in the system solar and the second planet from the sun. Compared to other planets, it completes a round trip in a longer time and also in the opposite direction to 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. Venus' atmospheric composition is approximately 96.5% CO2, 3.5% nitrogen, and traces of SO2, HCL, and HF. Compared to Earth, Venus' atmosphere is denser and the nitrogen content is almost four times higher than that of Earth. Our main goal is therefore to design a probe that survives on the surface of Venus. We would then explore the condition of the troposphere extending from the surface up to 65 km radius of the planet. The air density at the surface is 67 Kg/m3 and the surface temperature is 740 K (467°C). The pressure at the surface is 90 atm Earth. It can be deduced that 99% of the atmosphere is within 28 km of the planet. There are also other factors that should be defined, Venusian clouds composed of SO2 gas and H2SO4 droplets, the thickest layer of this cloud exists within the troposphere (~48 km). The strategy adopted to address this problem first involves a comprehensive study to observe the environment of Venus and the history of missions launched to explore Venus. Secondly, the list of problems that cause the failure in the operation of the probe is extracted. Let's take a look at the brief history of space probe failures at the beginning of the era. Venera 3 was the first spacecraft to land on Venus in 1966. Venera 2 failed due to overheating, shortly before completion of the mission. And it was the sister spacecraft of the later version, which landed successfully. Subsequently, in 1967, Venera 4 managed to return measurements taken directly from the planet. Later, in 1969, the results were verified by Venera 5 and Venera 6. In 1970, Venera 7 managed to stay on the surface of Venus for only 23 minutes due to high temperature intolerance. The main problem for those looking for the solution is only the high temperature and harsh environment. In the next one.
