JUICE Mission's Unexpected Comet Encounter

The JUICE mission, headed to Jupiter, has a surprising chance to study a rare comet. This mission aims to explore Jupiter's icy moons, Ganymede, Callisto, and Europa, which may have hidden oceans and potential for life. Ganymede, the largest moon, is unique with its own magnetic field, and JUICE will be the first spacecraft to orbit it. JUICE is on a slow journey to Jupiter, expected to arrive in the early 2030s. Right now, it's in deep space, perfectly placed to observe comet 3I/ATLAS. This observation wasn't planned, but the opportunity was too good to pass up. The spacecraft will observe the comet twice, even though it won't get very close. The closest approach will be on November 4, when the comet is about 64 million kilometers away. Despite the distance, JUICE has the right tools to study the comet. It will use five instruments, including a camera and spectrometers, to gather data. However, due to its position, the data will take a while to send back to Earth. Scientists expect to receive all the data by February 2026. While waiting for JUICE's findings, there's good news for stargazers. The comet is moving away from the Sun, and Earth is moving towards it. This means we'll have better chances to see it from our own backyards in the coming months.
