Lorenzo Iorio, the gravitational dynamics researcher, has a melliflous name for the outermost solar planet - Telisto.

I had to read https://arxiv.org/abs/1512.05288 to understand what this meant, and frankly, I don't think the author has the standing to name this object.

Here's a proposal for a solar sail craft that would attain a velocity of 400 km/s, which is 1 AU every 4 days. That could reach a distance of 1,000 AU in about thirty years. That would provide the necessary specs for this and many other objectives.

The strategy is to put a spacecraft into an orbit that brings it close to the Sun, then open the solar sails at that time. I don't know if the specifics are in order, but the general principles seem sound. It might be the cheapest way to achieve a certain range of velocities.

Hey, there may be a new "best actual engineering demonstration" for sails.

The "plasma magnet sail"

It's a magnetic sail that traps the solar wind using current induced in solar plasma instead of current in a solid superconducting ring.

That's roughly analagous to the advance in electric generation which occured when designs switched from "magneto" with a rotating iron bar magnet
to the "dynamo" where the magnetic field is created by current flowing through field coils.

Propbably the most interesting sail proposal I've ever seen -


Combined that with the recent work on Magneto Aeroshell Braking for stopping.
https://www.nasa.gov/feature/magnetoshell-a...-space-orbiters You might not need a heavy rentry shield and meters-wide parachute, if you've got a tunable magnetic field...


Combine the two, and suddenly you've got some extremely interesting real entineering "electromagnetic propulsion" possibilites.
