NASA launches three spacecraft into gas giant The two, Galileo and Cassini, were at the end of their mission when they met in Jupiter and Saturn. But Galileo’s spacecraft arrived with a passenger – an investigation designed to throw it into a huge atmosphere of gas.
About an hour after NASA reached 93 miles (150 km) of Jupiter’s atmosphere, it lost contact with Galileo’s investigation. Scientists are not sure how deep they were before Jupiter’s extreme pressure and temperature disappeared. But can we one day send a space shuttle to Jupiter or Saturn for a huge gas? Since these giant planets may not have a solid ground on which to fall, can a spacecraft fly through a gas giant?
According to Lee Fletcher, Associate Professor of Planetary Sciences at Leicester University in the United Kingdom, the short answer is “no.” A space shuttle could not survive the gulf.

The problem with trying to fly through a gas giant is that “density, pressure and Temperature As you enter the interior, everyone will rise to higher levels. Hydrogen Probably a Liquid iron, He continued to make this region “like a stranger in the sun.”
To feel the pressure near the center of Jupiter, the Mariana Trench On Earth, The deepest place in our oceans. At depths of 11 miles (11 km), pressures reach only 1,000 bar (100,000 kPa), which is about eight tons per square inch (703 kilograms per square meter). At sea level 1 you will experience pressure (100 kPa). Near the center of Jupiter, pressures push up to megabytes, or one million bars, Fletcher said. At those massive pressures, temperatures also rise to tens of thousands of kelvins, equivalent to tens of thousands of degrees Celsius.
At that point, any spacecraft will not just melt or melt – it will completely fall apart Atoms, Fletcher said.
As it moves toward the center of Jupiter, it may encounter a space shuttle.
First of all, the best gas giant detection should be like shooting, improving aerodynamics and allowing it to go as low as possible, Fletcher said. As the spacecraft begins to descend, it will encounter clever ammonia clouds due to a similar scattering phenomenon in the Earth’s atmosphere and can pass through the blue sky.
“Gun, red, brown”80 km) Deep, “high” area cumulonimbus clouds, Possibly accompanied by severe lightning storms, Fletcher said.
Then, between 4,350 and 8,700 miles (7,000 to 14,000 miles), the spacecraft will experience a warmer atmosphere and the atmosphere itself will light up, Fletcher said. This temperature rises by tens of thousands of degrees Celsius and increases the pressure to megabytes. And this is where the spacecraft begins to disintegrate.
In this still mysterious interior of Jupiter, hydrogen and Helium Be liquid. From Juno’s mission, which A.D. It was launched in 2011, Scientists have discovered that Jupiter does not have a strong core, but rather a distributed material. Nitrogen, Carbon And in fact Iron. “You are no more,” Fletcher said, “until you get to this” blurred, confused “core.
But Fletcher loves to be a poet about these things. Yes, Galileo, the probe, Cassini, and our rocket-propelled grenade launches into their respective gas masses, but those atoms “will forever be part of these giant planets. You have nothing to add. It’s really lost from the giant planet. “
