But neither Io nor Europa have a magnetic field, as Ganymede is the largest satellite not only among the moons of Jupiter, but also among all the satellites in the Solar System. Returning to the atmosphere of Jupiter itself, it is worth believing that his research was carried out by Galileo, or rather by his atmospheric probe, which turned on at an altitude of 350,000 kilometers above the clouds of Jupiter and after 6 hours at a speed of 48 km/s he touched the atmosphere of the planet and spent 57 seconds only on the braking process.
Its sensors detect a sharply increasing temperature value, which reaches values of 16,000 degrees Celsius. The exhaust parachute helps by reducing the speed to 120 m / s and this happens only in the upper layers of the atmosphere, which was higher in magnitude only at the beginning, and in small subsequent layers is equal to the Earth’s atmosphere. The second main parachute also opens, reducing the speed to 27 m / s, which also reduces the temperature, after which the most important information about the structure of Jupiter’s atmosphere is transmitted within an hour, the overall temperature is also measured, a huge number of lightning is recorded, which are very common in such dense clouds of the planet. In addition, data on the energy received from the Sun is recorded, with a comparison of the energy, the emitter of which is the core of the planet.
At a depth of 180 km, at a temperature of 150 degrees Celsius and a pressure of 2,300,000 Gpa, which is comparable to an atmospheric pressure of 101,325 Pa in 22.7 atmospheres, the radio transmitter overheats and the device stops transmitting information. However, it continues its flight for several hours, the temperature and pressure begin to rise, leading to the fact that it eventually melts and evaporates in the vast atmosphere of the planet, turning into a part of it.
Galileo ended its existence, having received the same fate after 8 years of incessant service. But it is worth saying that this is only the beginning of the journey and the time will come when it will be possible to talk about creating more powerful devices equipped with new nuclear engines using thermonuclear or resonant nuclear reactions. The energy obtained from such energy sources will be sufficient to penetrate to a greater depth, supporting a thicker shell structure capable of withstanding higher atmospheric pressures, while continuing to penetrate into the deep layers of the atmosphere. In addition, paying attention to the chemical composition of Jupiter, which is dominated by hydrogen, nitrogen and some other gaseous compounds, there is a huge ocean of liquid hydrogen, which subsequently turns into a solid core.
