SUMMARY
The James Webb Space Telescope (JWST) requires propellant to maintain its trajectory around the Lagrange point L2, as orbits in this region are inherently unstable. Once the propellant is depleted, the JWST will drift away from L2 and potentially enter a wide Earth orbit, influenced by the gravitational forces of the Sun and other celestial bodies. A simulation referenced in the discussion suggests that the JWST could end up in a resonant orbit with the Moon, similar to the orbits of Jupiter's Galilean satellites. This scenario highlights the importance of propellant for maintaining the telescope's operational stability.
