ESA JUICE probe targets dark Jovian moon Kallichore in 2031

ESA's JUICE probe is set to study the dark Jovian moon Kallichore in 2031, with the goal of preparing for a potential flyby. The researchers found that Kallichore has an area-equivalent diameter of about 3.8 kilometers, making it one of the smallest moons in the solar system. Its geometric albedo is 0.037, indicating it is extremely dark. These measurements will help JUICE mission planners determine a more precise flyby trajectory. The study was conducted using data from NASA's Hubble Space Telescope and the Gran Telescopio de Canarias. The findings provide valuable information about Kallichore's orbit, which is crucial for planning the flyby.

The study highlights the importance of irregular moons in understanding the early solar system. These moons, like Kallichore, have remained largely unchanged since their formation, offering a more pristine sample of the solar system's history. Of the 456 known solar system moons, 396 are irregular, with about 87% of them being irregular. The research on Kallichore will help scientists better understand the formation and evolution of the solar system. The findings will also assist in planning the JUICE mission, which aims to study the icy Galilean moons and determine if they host conditions suitable for life. The study's results will contribute to the broader understanding of Jupiter's moons and their potential to hold clues about the early solar system.
