Is it possible to fly through Jupiter?

With the first acquaintance with Jupiter - the fifth from the sun of the planet of the solar system - we immediately learn that it consists of gas. Usually we imagine gas, as a kind of air substance, through which you can easily pass / drive / flew. So why not do it and Jupiter?

Jupiter, like all other planets, has a ball shape. What makes him so? Of course, gravity, which on all sides with a terrible force squeezes matter, forcing it to gather it in one place and take the form of sphere. The closer to the center of the sphere, the stronger the level of pressure is increasing due to the "above" substance. In a huge compared to the land of Jupiter, the pressure level of thousands of times higher than on our planet. In turn, the higher the pressure rises, the more the temperature becomes: the calculations show that in the center of Jupiter, the temperature may be so high, which exceeds even the temperature on the surface of the Sun.

Imagine that the spacecraft still decided to try to fly through the gas giant and, finally, overcoming many difficulties on the way to Jupiter (for example, the belt of asteroids - Is it possible to safely fly through the asteroid belt?), it begins to enter Its atmosphere, which practically consists of molecular hydrogen and helium.

This is interesting: The atmosphere of Jupiter is the largest among all the planets of the solar system and is in a height of about 5, 000 km.

At first, the ship, passing the layers of hydrogen and helium, will meet the clouds of the explosion of ammonia, and then, with an increase in pressure and temperature, the clouds from the smallest drops of liquid water. Below atmosphere begins a layer of about 20, 000 km long, where under the influence of pressure and temperature hydrogen moves from the gaseous state into liquid. Even below, the temperature and pressure becomes extreme, creating a layer of about 45, 000 km long, where hydrogen moves into a metal state (the so-called layer of metallic hydrogen). The latter in this list goes the kernel. What exactly is the kernel of Jupiter is exactly unknown, but it can be assumed that its foundation is heavier than helium elements, and its mass is 10 times superior to the mass of the land core. In this case, its density and temperature is extremely high.

It becomes obvious that trying to fly through Jupiter on a spacecraft - a rather stupid undeunion. Although this planet is a gas giant, when exposed to temperature and pressure, gaseous compounds are moving into a liquid and metallic state, fly through which is not possible.

What is impossible to fly through Jupiter, repeatedly proved in practice a variety of objects, ranging from meteorites and comet, ending with cosmic probes. For example, in 1994 there was a grand collision of the comets of Schukeyaker-Levi with Jupiter.

Another example was the flight of the Galileo spacecraft with the help of which the studies of Jupiter and its satellites were conducted. After the end of the program, Galileo was decided to destroy, encountered it with Jupiter (the need for destruction was due to the prevention of the penetration of earthly microorganisms on the satellites of Jupiter, in the event of a possible collision with one of them). It was Galileo who passed on Earth worthless information about the composition of the atmosphere of the gas giant. Introducing the atmosphere of Jupiter to 868 km, the spacecraft stopped transmitting data.
