#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.

#1: Euclid completes thermal-vacuum balance tests
10 October 2019

This is the first entry in the Euclid Test Campaign Journal, a series of articles covering the main events during testing of the Structural and Thermal Model (STM) and Flight Model (FM) of the spacecraft.
