JUICE intro

JUICE - JUpiter ICy moons Explorer - is the first large-class mission in ESA's Cosmic Vision 2015-2025 programme. Planned for launch in 2022 and arrival at Jupiter in 2029, it will spend at least three years making detailed observations of the giant gaseous planet Jupiter and three of its largest moons, Ganymede, Callisto and Europa.

#8: Successful integration of JUICE's 10.6-metre-long arm
15 April 2021

The development of ESA's JUpiter ICy moons Explorer (JUICE) is continuing apace and has hit milestones in recent months: the spacecraft's 10.6-metre-long boom is now attached, many instruments have been integrated, and the mission's high-gain antenna has arrived and undergone rigorous vibration testing.

#7: All panels delivered for JUICE's solar wings
16 October 2020

All ten flight model solar panels for ESA's JUICE spacecraft have been delivered to Airbus Defence and Space Netherlands ready to be integrated into solar wings. The solar panels, with a total area of 85 m², are a key element of the mission, providing the necessary power to run the spacecraft and operate the science instruments.

#6: Start of assembly and integration for JUICE
26 June 2020

Despite certain operational difficulties caused by the COVID-19 pandemic, the assembly and integration of the flight model for ESA's JUpiter ICy moons Explorer (JUICE) spacecraft has continued with few delays during the first six months of the year.
