# Europa Clipper: NASA\u2019s mission to Jupiter\u2019s ocean moon

**Answer:** Europa Clipper, launched Oct. 14, 2024, is the first mission designed to conduct a detailed study of Jupiter's moon Europa. Its main science goal is to determine whether there are places below Europa's icy surface that could support life.

## The trip

The spacecraft is traveling 1.8 billion miles (2.9 billion kilometers) to reach Jupiter in April 2030. It will orbit Jupiter and conduct dozens of close flybys of Europa.

## The spacecraft

Europa Clipper is a robotic solar-powered spacecraft. With its solar arrays deployed it spans more than 100 feet (about 30 meters), about the length of a basketball court. Its main body consists of its avionics vault, radio frequency module, and propulsion module.

## Why Europa

- Scientists believe a saltwater ocean lies beneath Europa's icy shell, holding twice as much water as Earth's global ocean.
- Europa also may have the chemical elements that are key ingredients to life.
- Europa may be one of the most promising places in our solar system to find present-day environments suitable for some form of life beyond Earth.

## About Europa

Europa is the fourth largest of Jupiter's moons and the sixth-closest moon to the planet. It was first observed up close during the Jupiter flybys of Pioneer 10, Pioneer 11, Voyager 1 and Voyager 2. Most of what we know about the moon comes from the Galileo mission.
