The Great Red Spot is a gargantuan, high-pressure vortex called an anticyclonic storm that has been raging in Jupiter's southern hemisphere for at least 350 years. The storm's physical width has varied in roughly 150 years of observation, but it's believed to be more than 10,000 miles wide – more than enough to contain the entirety of Earth.

After a 1.8 billion-mile journey, the uncrewed spacecraft is expected to settle into orbit around Jupiter in 2030, in an endeavor to find out if the moon, Europa, is habitable.

It is a big mission for NASA’s huge spacecraft the Europa Clipper. Traveling nearly two billion miles to Jupiter’s moon, Europa. The ship is NASA’s largest ever to travel through space on this one-of-a-kind mission.
