Exciting Jupiter Mission Set to Capture Images of Interstellar Comet 3I/ATLAS: A Surprising Adventure for Scientists!

Comet 3I/ATLAS has been the talk of the astronomical community since its discovery just over four months ago. This comet is special; it’s only the third interstellar object confirmed to have passed through our Solar System. Despite countless celestial visitors, interstellar comets are rare. Scientists around the world are keenly studying this striking object.

One fascinating mission set to observe Comet 3I/ATLAS is the European Space Agency’s JUICE (Jupiter Icy Moons Explorer). JUICE isn’t just any spacecraft; its goal is to understand the icy moons of Jupiter—Ganymede, Callisto, and Europa. These moons may hold vast oceans beneath their surfaces. JUICE will even be the first spacecraft to enter orbit around Ganymede, the Solar System’s largest moon, which has its own magnetic field.

JUICE is slowly making its way through the inner Solar System, following a careful trajectory. It will make flybys of Earth and Venus to save fuel on its way to Jupiter, aiming to reach the gas giant in the early 2030s. Serendipitously, JUICE will also come near Comet 3I/ATLAS, which will be about 210 million kilometers from the Sun during this time.

“JUICE will observe 3I/ATLAS from November 2 to November 25,” explained Olivier Witasse, ESA Project Scientist. The spacecraft will employ five different instruments to gather data, although it will be engaging in remote sensing from half an astronomical unit away—meaning it won’t get very close. However, this presents an unexpected chance to observe an interstellar comet, a truly unique opportunity.

Witasse noted, “This campaign was unexpected for everybody.” The JUICE mission was in a cruise phase, and no science activities were planned at this stage. Yet, the chance to capture images of Comet 3I/ATLAS was too exciting to pass up.

Right now, Comet 3I/ATLAS is difficult to see due to the Sun’s glare. NASA and ESA have deployed robotic explorers on Mars to help capture initial images of the comet. However, it will take time for this data to be transmitted back to Earth. “The data rate is very low. We expect to receive it by February 2026,” Witasse added. Patience will be crucial for astronomers eager to learn more about this cosmic wanderer.

For those curious about how Comet 3I/ATLAS compares to past interstellar visitors: it echoes the historic moments of discoveries like ‘Oumuamua, the first known interstellar object observed in 2017. Both comets offer insights into the origins of our Solar System and beyond.

As 3I/ATLAS approaches its closest point to Earth on December 19, it will still be a distant 268 million kilometers away. But even from afar, it has sparked enthusiasm and curiosity among science lovers and casual observers alike.
