... INTRODUCTION
Hydrogen is the simplest and most abundant of elements. ... On Earth, hydrogen can be found in gas state. But on Jupiter, where interior pressure is greater than of Earth, the hydrogen molecule is found in both liquid and metallic states.
Since the 1930’s, scientists have theorized of solid hydrogen to become a metal when it is compressed, but, while studies of the this material led to discovery of hydrogens solid and liquid phases, metallic hydrogen remained out of reach, until recently. ... A HYDROGEN PLANET: JUPITER
Jupiter is the most massive of the Jovian planets, containing 71 percent to all the planetary matter in our solar system. ... Scientists have speculated and concluded that Jupiter is mostly composed of hydrogen and helium, in different states. (Horizons: Exploring the Universe)
Jupiter’s Theoretical Model, based in its density, divides the planet in several sections: the atmosphere, mostly of hydrogen gases; hardly distinguishable, the outer layer of the planet, which is a mix between the gas and a liquid state of hydrogen; an upper inner layer of liquid hydrogen, due to the interior pressure compressing the gas; a middle inner layer, where the internal pressure is so great that converts the liquid hydrogen into metallic hydrogen; and at the center, a “rocky” core, which contains heavier element, such as iron, nickel, silicon, etc. ... TWO-STAGE GAS GUN
In the quest to obtain hydrogen metallic, the most crucial equipment used is a 20-
meter-long, two-stage light-gas gun. ... 5 kilograms of gunpowder and a pump tube filled with 60 grams of the gas being studied (hydrogen in this case); and a second-stage evacuated barrel for guiding the high-velocity impactor to its target. ... The preferred velocity is achieved by selecting the appropriate type and amount of gunpowder, driving gas (hydrogen for velocities at or above 4 kilometers per second), pressure required to open the rupture valve, diameter of the barrel, and the metal and mass of the impactor.
