Juice: an ESA-led global collaboration

Through developing and implementing the Jupiter Icy Moons Explorer (Juice) mission, ESA is leading a global collaboration that is already bringing socio-economic benefits to Europe and the rest of the world. These benefits are set to continue once the mission has launched.

The mission is a true cooperation between people with a variety of skills to offer. Some key numbers include:

• 18 institutions
• 23 countries
• 83 companies
• 116 industry contracts
• >2000 people
• ~1.6 billion euros (mission cost)

Juice will make detailed observations of Jupiter and its three large ocean-bearing moons – Ganymede, Callisto and Europa – with a suite of instruments. The mission will characterise these moons as both planetary objects and possible habitats, explore Jupiter’s complex environment in depth, and study the wider Jupiter system as an archetype for gas giants across the Universe.
