The short answer is 'no.' A spacecraft could not survive a trip through a gas giant. 🪐😞
NASA has plunged three spacecraft into gas giants. Two of them, Galileo and Cassini, were at the ends of their missions when they met their doom in the atmospheres of Jupiter and Saturn, respectively. But the Galileo spacecraft arrived with a passenger — a probe designed to drop into a gas giant atmosphere.
According to Leigh Fletcher, an associate professor of planetary science at the University of Leicester in the United Kingdom, the short answer is"no." A spacecraft could not survive a trip through a gas giant. The problem with trying to fly through a gas giant is that"the density, pressure and temperature all increase to such enormous levels as you penetrate down into the interior," Fletcher told Live Science.
At that point, any spacecraft wouldn't be just squished or melted — it would entirely disintegrate into its constituent atoms, Fletcher said.First, the ideal gas giant probe would have to be shaped like a bullet, to improve aerodynamics and allow it to plummet as far down as possible, Fletcher said.
In this still-mysterious region of Jupiter’s interior, hydrogen and helium become a fluid. From the Juno mission, which launched in 2011, scientists have figured out that Jupiter doesn't have a solid core but rather a diffuse core of materials including nitrogen, carbon and even iron. By the time you get to this"fuzzy, mixed" core,"you're no more," Fletcher said.
