The COMmunity of ExperTs in ORBital mechanics deals with all subjects relating to space vehicle trajectories.

This community aims to lead and prompt discussions on all aspects of the life of these vehicles (from launch to re-entry), from the most theoretical aspects to the most practical aspects.

The JUICE Lunar-Earth Gravity Assist: from Inception to Completion

ORB - Orbital mechanics

In August 2024, the JUICE spacecraft performed a very special manoeuvre: the first-ever Lunar-Earth gravity assist (LEGA) manoeuvre. The concept was invented at ESOC in Summer 2013. In a first phase, the potential of the concept was analysed in detail by mission analysis, and its navigability was carefully studied to ultimately include it in the JUICE baseline. Once in flight, the key was accuracy and safety. These aspects were successfully handled by the ...
