Is it possible to focus on a reflection on the Voyager spacecraft; or how aren't communications ever affected by lack of line of sight?
So there was no way to flip around and counter-thrust due to the velocity by that point in Voyager's trajectory (without a gravitationally-assisted slowdown or waiting for planetary orbits to align the same or in a feasible way)

Aren't there hypotrochoid orbits to accelerate and decelerate using planetary gravity; gravity assist

- Vindication! KSP is what I probably would have used to answer questions like this; though KSP2 doesn't work in Proton-GE on Steam on Linux and they've since disbanded / adjourned the KSP2 team fwiu.

TY for the explanation.
Hopefully cost effective solar sails are feasible.
FWIU SQR Superfluid Quantum Relativity doesn't matter for satellites at Earth-Sun Lagrangian points either; but, at Lagrangian points, don't they have to use thrust to rotate to account for the gravitational 'wind' due to additional local masses in the (probably vortical) n-body attractor system?
