Why Is It So Hard To Get To Jupiter's Moon Callisto?

Описание: In the vast cosmos that stretches beyond our planet, Callisto, Jupiter's second-largest moon, presents a fascinating destination for human exploration.
From an internal ocean beneath its surface to a size that borders on the planetary scale. Callisto is an icy, distant world that could represent the next place we look for extraterrestrial life and perhaps a future colony of humanity.
If Callisto is such an essential place for the human race, why haven't we yet sent rovers to explore its surface as we have Mars? perhaps, it is tough to get to Callisto?
Stay with us to find out!
Callisto is Jupiter's second-largest moon after Ganymede and the third-largest moon in the solar system after Ganymede and Titan. Callisto has a diameter of about 4,800 kilometers, almost as large as Mercury. Still, despite its size, it only has a third of the mass of Mercury, so its gravity is small in comparison.
This is because Mercury has a massive iron core, while Callisto also has metal in its core, but in a smaller proportion.
A satellite with a lot of history
Callisto's ancient surface is one of the most cratered in the Solar System. The density of the craters is close to saturation: any new crater will tend to erase an older one; it's like a minefield full of impact craters.
Large-scale geology is relatively simple; Callisto has no large mountains, volcanoes, or other technological structures. Impact craters and multi-ring structures, along with fractures and scarps, are the only prominent features found on the surface.

An Ocean of Possibilities
The first space probes to visit Callisto were Pioneer 10 and Pioneer 11, which passed close to Jupiter in the early 1970s. Still, since very little was known about Callisto then, both spacecraft passed by and captured little information about this satellite as they did not consider it a priority.
Callisto's Habitability
Although it's not as famous a moon as Titan or Europa, Callisto has water, enough for scientists to set their sights on it.
Observations of Callisto's inner ocean do not provide us with much information about it, as several factors could influence its temperature and density.

Could Callisto be humanity's future home?
