A Voyage to Icy Europa: NASA's Big Mission

You know how we're always looking for life beyond Earth? Well, NASA just sent a spacecraft on a long trip to one of Jupiter's moons. Europa is not just any moon, it's icy and might have a huge ocean below its surface. That's why scientists think it could be a great place to find alien life. The spacecraft, called Europa Clipper, lifted off from Florida on October 10, 2024. It's going to take a while to get there, about 5 ½ years, and it'll travel over 1. 8 billion miles! This isn't a quick trip, but it's going to be worth it. Europa Clipper will study the moon's ice and structure to see if it could support life. It won't look for life directly, though. It'll check if the moon has the right stuff, like water and energy.
Scientists think Europa's ocean might be twice the size of all Earth's oceans combined! That's a lot of water. The spacecraft will make 49 close passes by Europa over four years. It'll face some harsh conditions, like strong radiation from Jupiter's magnetic field. But the team has a plan to protect the spacecraft. It'll orbit Jupiter in a special way to avoid too much radiation. Before reaching Jupiter, Europa Clipper will swing by Mars and Earth for a gravity boost. This isn't NASA's first look at Europa, but it's the first dedicated mission. Europa was discovered a long time ago, in 1610, by Galileo Galilei. Scientists have been studying it since, but this mission is a big deal.
