NASA’s Europa Clipper has embarked on its long voyage to Jupiter, where it will investigate Europa, a moon with an enormous subsurface ocean that may have conditions to support life. The spacecraft launched on October 14, 2024 aboard a SpaceX Falcon Heavy rocket from Launch Pad 39A at NASA’s Kennedy Space Center in Florida. The spacecraft is the largest that NASA has ever built for a mission headed to another planet. Europa Clipper also is the first NASA mission dedicated to studying an ocean world beyond Earth. The spacecraft will travel 1.8 billion miles (2.9 billion kilometers) on a trajectory that will leverage the power of gravity assists, first to Mars in four months and then back to Earth for another gravity assist flyby in 2026. After it begins orbiting Jupiter in April 2030, the spacecraft will fly past Europa 49 times.
