SV-Hilda

Last year I found out about Hilda orbits, which orbit a large body at 3:2 resonance with a midsized body. Jupiter has a lot of these. I've scattered ideas what to do with the Sun-Venus Hilda-belt (0.552 AU, 150 days); I seem to have a critical mass, as it were, for at least a micro-fusion blogpost.

This belt can meet L3, L4, and L5 at slow speeds; the main planet at high speeds. UPDATE 12/24-26/22 J=-10.955. The Jacobi-Integral map suggests planet-capture orbit as the easiest route outward (3.0007826) followed by L3 (2.9999976, eeep). If the large body is the Sun it also gets more energy than the planet would; and, of course, energy for anything in-system becomes cheaper.

Ideally I'd move Mercury out to be this Hilda, but that's kinda gonzo. Although I think we'll end up gonzo enough. Human presence would be in a stone Rama because, well, it would have to be.

I'd considered using this orbit for occasional ferrywork between Mercury and Venus (Libration anyway). Another idea would be to dock rescue-vessel torch ships for anywhere else in the Solar System.

The Hilda does anything requiring even more energy than Venus gets, if we got time to spare between getting the product out the Solar well. Making antiprotons and tritium (which decays to Helium-3), especially; also endothermic chemistry like reducing silicon. The energy here should be enough to spark fusion reactions, which gives even more energy; enough to direct the neutrons somewhere decent, like toward making more tritium.

UPDATE 10/30: As to some actual maths on making tritium, meet CANDU: 100 grams per year for a 600 MW reactor. At Hilda, our reactor is the Sun. Just need surface area, to catch some rays.

Hilda can serve the B612 Foundation's Sentinel telescope at SVL3... might also be in some position to trap hydrogen and helium blazing out from the Solar wind. Tho' man does not live on hydrogen alone.
