🚀 As the MMX spacecraft departs Earth, another has just paid a return visit, despite launching in 2023. 🛰So why was JUICE, Europe’s mission to study Jupiter’s icy and potentially habitable moons, back at Earth?
Flying straight to Jupiter would take a huge rocket and vats of fuel. ➰ Instead, JUICE takes a looping route with several gravity-assist flybys: the gravity of Earth (and the Moon and Venus) provides nearly free speed and steering.
On 28 September, it passed within 8,640 km of Earth, high above the Indian Ocean, gaining 3.5 km/s and changing course by 20° while using barely any fuel. Along the way, JUICE snapped these pictures with its high-res JANUS camera, built with help from DLR.
Next stop: 🌍 Earth (again) in January 2029 – then Jupiter in July 2031.
