The JUICE mission of the European Space Agency is set to complete a new manoeuvre and break two records.
This is the first time the spacecraft will use two objects to carry out a gravity assist manoeuvre, and for the first time, it will also attempt Lunar-Earth flyby.
The spacecraft will first go around the Moon and losing some of its speed.
After 25 hours, it is expected to approach Earth.
Because of Earth, it will slow down further and go towards Venus.
