In what NASA’s Jet Propulsion Laboratory has dubbed “the year of the icy world,” the agency will see three separate spacecraft begin the unprecedented exploration of dwarf planets and a moon over a period of just eight months. While these missions are underway, NASA is also ramping up planning for Europa Clipper, a planned robotic exploration of the Jovian moon Europa, which early in February effectively moved from concept to mission status under the agency’s latest budget announcement.
