Why are probes landing on Jupiter or Saturn unlikely events?

Answer 1

Here are a few reasons

1. Because the large mass of these planets causes a strong gravitational pull that would destroy any probe that landed there.... most would be destroyed long before impact.

2. There is no known "land" as we tend to think of it. It's just a gas that gets thicker and thicker is the common viewpoint.

However, I personally think there's probably some phase transition point that could be construed as a "surface".

Think of the earth. If it was only ocean, could anything truly "land"? You would go through layers of atmosphere, then hit liquid water. Do you consider that the surface (assume you're an alien) or do you keep going until you hit a rocky bottom?

3. Jupiter has the equivalent gravity which would add approximately 6000 lbs to your weight.

It also has an atmospheric pressure of approximately 22atm

A probe would have to survive deep sea exploration, just to be able to with stand that sort of pressure.

Then you have to account for the space travel, a probe strong enough would have much higher mass and would be harder to propel from Earth's gravitational pull.

4. Not just unlikely. Impossible. These planets have no surfaces that can be reached. They have cores, but they are so deep that nothing could ever get to them. All you can do on these gas giants is drop a probe by parachute or perhaps attached to a balloon which it deploys and then stays aloft at a certain altitude for awhile.

It would also be considered that a parachute or balloon would have a slim chance of surviving the pressure as well.

Answer 2

Jupiter and Saturn are gaseous planets comprising of dust and gas
It is unlikely because both Jupiter and Saturn are made up different gasses and lack a "hard" surface.

Answer 3

the most probable answer is that Jupiter and Saturn are gaseous planets,comprising of dust and gas.
