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. Europa Clipper's three main science objectives are to determine the thickness of the moon's icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission's detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet. https://photojournal.jpl.nasa.gov/catalog/PIA26433
