ESA JUICE probe targets dark Jovian moon Kallichore in 2031

The European Space Agency’s Jupiter Icy Moons Explorer (JUICE) mission is set to study Jupiter’s icy moons, with a particular focus on Kallichore, a small, irregular moon. Researchers used telescopes to measure Kallichore’s size and brightness, finding it to be a perfect sphere with an area-equivalent diameter of 3.8 kilometers and a geometric albedo of 0.037, indicating it is extremely dark. These measurements will help refine the trajectory for JUICE’s planned flyby in 2031. The study supports the idea that irregular moons like Kallichore can provide a pristine record of the solar system’s early history, as they have remained largely unchanged since their formation. The findings will aid in planning the flyby and help scientists understand the conditions on Jupiter’s moons.

• The study was conducted using NASA’s Hubble Space Telescope and the Gran Telescopio de Canarias.
• Kallichore’s irregular orbit was studied to improve JUICE’s flyby trajectory.
• The measurement of Kallichore’s albedo and size will help in planning the spacecraft’s path.
• The research highlights the importance of irregular moons in preserving solar system history.
• JUICE will study the icy Galilean moons to assess their potential for habitability.
• The mission is expected to provide insights into the formation and evolution of the solar system.
• The study is part of a broader effort to understand Jupiter’s moons and their potential for hosting life.

The findings underscore the value of irregular moons in preserving solar system history and the importance of precise measurements for future space missions. The data collected will help refine the trajectory for JUICE’s flyby and contribute to the broader understanding of Jupiter’s moons and their potential for habitability.
