The European Space Agency's Juice spacecraft performed a gravity-assist flyby of Earth on September 28, using the planet's gravity to reshape its trajectory toward Jupiter while conserving fuel. The maneuver altered Juice's direction by 20 degrees and boosted its speed by 3.5 km/s. The flyby also gave mission scientists a rare opportunity to test Juice's scientific instruments on familiar targets—Earth and the Moon—ahead of its arrival at the Jovian system.
