Galileo looked at the planet Jupiter and observed its 4 largest moons (which are still known as the Galilean moons, to this day).
we can't use jupiters moons for anything because fistly we can not get out that far to reach Jupiters moon and if we could it would take thousands of years and Jupiters Moons would be to big to do anything with anyway. so the answer to What could Jupiter's moons be used for? is....Nothing.
it's moons

Socrates, Gallileo
He could only make out four of Jupiters' largest moons.
Galileo Galilei made significant contributions to astronomy, physics, and mathematics. He improved the telescope, discovered the moons of Jupiter, observed sunspots, and supported the heliocentric model of the solar system. Additionally, he formulated the laws of motion and conducted experiments on falling objects.
He found the Galiliean Moons and improved the telescope.
