AI Insight
The European Space Agency's Jupiter Icy Moons Explorer (Juice) successfully completed a gravity assist maneuver by flying through the outer edge of Earth's atmosphere on September 28. This flyby used Earth's gravity to redirect the spacecraft's trajectory toward Jupiter while conserving fuel. The maneuver is part of Juice's planned route to reach Jupiter and study its icy moons.
Why it matters
Gravity assist maneuvers are critical for deep space missions as they enable spacecraft to reach distant destinations without carrying excessive amounts of fuel, making such missions economically and technically feasible. This successful flyby demonstrates the precision of orbital mechanics calculations required for complex interplanetary missions.
Understand the Science
The European Space Agency’s Jupiter Icy Moons Explorer (Juice) skimmed the very outer edge of Earth’s atmosphere on 28 September, using the gravity of our home planet to alter its route to Jupiter using very little fuel.
