The European Space Agency (ESA) plans to send a probe to Venus – the hottest planet in our Solar System. The mission called EnVision should start in the early 30s of this century, not long after the DAVINCI mission.
The device in question will have to face a number of challenges. At the top of their imaginary list, as expected, is Venus’ “hot and dense atmosphere,” made up mostly of carbon dioxide.
From the available information, it appears that ESA wants to rely on the proven method of “aerbraking”. This involves a significant deceleration of the probe, which will allow it to lower its trajectory just above the inner edge of the atmosphere.
During this phase, he tries to gather as much interesting information as possible about the planet below him. If all goes according to plan, the whole process will be repeated many times.
In order to take the best possible images, the probe will descend to a height of only 150 km above the surface of Venus, which means that it will have to be able to “surf” through its atmosphere unscathed.
Therefore, ESA engineers are already testing a number of different materials and coatings that could theoretically protect sensitive scientific instruments.
