The Juno probe captured eerie sounds from the Jupiter Moon Ganymede.

The radars and new laser altimeters are multipurpose tools. Those systems can use to measure distances between the objects. They can measure the depth of the oceans. And they can turn to laser-and radar microphones that can capture sounds from other planets and moons of our solar system.
The moving ice above the oceans of the icy moons and the tidal waves inside those moons are causing eerie and interesting sounds. That kind of sound can hear by using remote microphones.
The thing is that the "water magma" below icy moons is causing the situation that the location of the possible Jupiter base must re-estimate. The icy cores of those moons can break. And tidal forces of the giant planet are causing the situation that the water flow below the ice core is very high.
The sensors of the Juno spacecraft are very versatile, and also things like impacting ions to the ice moon are causing sound effects. The magnetic field of Ganymede can be the source for some of those eerie sounds. The Ganymede is the only known moon in our solar system. That has stable magnetic fields.

The ocean itself offers good protection against the radiation of Jupiter. It also offers water for drink and plantages. Also, water is a good tool for propellant for conventional and electrostatic engines. In electrostatic engines, electromagnetic radiation replaces normal combustion. In "conventional" electrostatic engines. An electric arc vaporizes the propellant, which expands. And that expansion is forming a thrust.
The water itself can use as a propellant in microwave or laser engines. In microwave rockets, the microwaves vaporize some other materials like liquid hydrogen or water or even some metals like quicksilver. And that vapor is the thing that pushes the craft forward. Same way laser can turn water to vapor, and that expansion replaces the burning in the rocket combustion chamber.
But the eerie sounds and possible primitive lifeforms are causing a dangerous situation. The human mind would start acting quite differently if those astronauts are at the place, where returning takes many years. And the noise that the water flow and moving ice core are causing is very stressful.
