Alright, I should probably do more work on this old thing, but I actually quite like the concept. Travel times to and from Saturn using constant acceleration...of one Earth gravity! Quite achievable with nuclear pulse propulsion...

"Outer solar system at 1g parchment map", by yours truly.

🍾 Simulations show Saturn's moon Enceladus shoots less ice into space than previous estimates

2025 GE (discovery circular): https://www.minorplanetcenter.net/mpec/K25/K25G49.html -> why it was important: https://groups.io/g/mpml/message/40643 - "a large, inclined object with low eccentricity between Uranus and Neptune. And it's by far the brightest distant object discovered in the last decade. Nothing this bright has been linked since 2014 WP509!" #OuterSolarSystem

Interesting results: a "kiss-and-capture" origin for the Pluto-Charon system. https://www.nature.com/articles/s41561-024-01612-0

I'm no dynamicist, but it sounds like the same scenario that probably resulted in the observed structure of Arrokoth. (Except they stuck together.)

Now brainstorming: more details of the outer solar system grand tour and characterization of the cosmonaut who will undertake it.

New Horizons to become active again! 🙂

"It has now begun its second extended mission, and is soon set to wake up from a deep hibernation, opening a wealth of new science opportunities in the outer solar system."
