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. http://knowyourmeme.com/memes/stop-trying-...ke-fetch-happen -------------------- Disclaimer: This post is based on public information only.

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. https://arxiv.org/pdf/physics/0701073.pdf 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 -
Plenary talk by Jeff Greason, Board Chairman, Tau Zero Foundation, Oct. 5, 2017, Huntsville, AL https://www.youtube.com/watch?v=0vVOtrAnIxM 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. |
