Story summary

Researchers at the Beijing Institute of Technology suggest using moons for gravity assists to improve orbital maneuvers.
This approach could lower fuel needs for missions, particularly in the Jovian system, but is not applicable to current missions like JUICE.
The study emphasizes "weak stability boundaries" (WSBs) for stable orbits around multi-moon planets like Jupiter.
Simulations indicate substantial fuel savings using Callisto for gravity assists, enhancing future interplanetary mission possibilities.
These findings aim to reshape strategies in astrodynamics and planetary exploration.
