JUICE Mission: To visit the Jovian system, focusing on studying three of Jupiter’s Galilean moons: Ganymede, Callisto, and Europa Next Slide

JUICE Mission Timeline: • Launch—June 2022 • Rocket—Ariane 5 ECA • Launch site—Guiana Space Centre in Kourou, French Guiana, France • Jupiter orbital insertion—January 2030 • Ganymede orbital insertion— 2033 Mission Scenario and Operations Next Slide

JUICE Mission Science Objectives: • Perform detailed investigations on Ganymede. • Evaluate Ganymede’s potential to support life. • Investigate Europa and Callisto to complete a comparative picture of the Galilean moons. • These three moons are thought to harbor internal liquid-water oceans and are central to understanding the habitability of icy worlds. Next Slide

JUICE Mission Science Objectives for Ganymede and to a lesser extent for Callisto: • • • Characterization of the ocean layers and detection of putative subsurface water reservoirs Topographical, geological and compositional mapping of the surface Study of the physical properties of the icy crusts Characterization of the internal mass distribution, dynamics and evolution of the interiors Investigation of Ganymede’s tenuous atmosphere Study of Ganymede’s intrinsic magnetic field and its interactions with the Jovian magnetosphere Next Slide

JUICE Mission Science Objectives for Europa: • The focus is on the chemistry essential to life, including organic molecules • On the formation of surface features and the composition of the non water-ice material • Subsurface sounding of the moon, including the first determination of the minimal thickness of the icy crust over the most recently active regions • More distant spatially resolved observations will be carried for several minor irregular satellite and volcanic moon Io Next Slide

JUICE Mission

JUICE Mission

JUICE Mission Scenario and Operations: The JUICE spacecraft will be launched in June 2022 by Ariane 5 and will use Venus and Earth gravity assists in its 7. 6 years cruise to Jupiter. After the orbit insertion in January 2030 the spacecraft will perform a 2. 5 year tour in the Jovian system focusing on continuous observations of Jupiter's atmosphere and magnetosphere. During the tour, gravity assists with Callisto and Ganymede will shape the trajectory. Two targeted Europa flybys are included focusing on composition of the non water-ice material, and the first subsurface sounding of an icy moon. Additional, Callisto gravity assists will be also used to raise the orbit inclination to almost 30° and to enable observations of the Jupiter polar regions. The frequent Callisto flybys will enable unique remote observations of the moon and in situ measurements in its vicinity. The mission will culminate in a dedicated eight months orbital tour around Ganymede during which the spacecraft will perform detailed investigation of the moon and its environment and will eventually impact on Ganymede.
