Europa Clipper: NASA’s Largest Planetary Spacecraft (Artist’s Concept)

With its solar arrays and antennas fully extended, the Europa Clipper spacecraft stretches out larger than a basketball court: approximately 100 feet (30.5 meters) long and 58 feet (17.6 meters) wide. Depicted in this artist's concept against an illustration of a basketball court, Europa Clipper is the largest spacecraft NASA has ever built for a planetary mission. Europa Clipper is bound for the Jupiter system, where it will study the gas giant's icy moon Europa.
