I have three forms-
Lanky bastard, beefy nerd, and nuclear excavator.

Me to myself ( I need to stop lurking ( seriously I have so many art projects nobody sees because I never post them ( also none of them are ever actually finished ) ) )
@ziphi Wishing you luck. The no fuel glitch sounds brutal. I've been playing the For Science! update a bit recently, sent missions to Duna, Eve, and Jool. Only major annoyance I've had is the ability to burn during timewarp doesn't seem to apply to ion engines, which would have been GREAT to know BEFORE I sent interplanetary probes that had hour-long braking burns in the mission plan...
@chickfilla Finding decent sources of uranium on the moon is probably difficult, because the moon formed as a molten lava ball that allowed heavier elements to sink to its core, and it also lacks mechanisms to concentrate whatever is left in the crust into ores like on earth. (Double checking https://en.wikipedia.org/wiki/Lunar_resources seems to confirm my suspicions) Asteroids on the other hand can be a good source because some of them were never part of a body large enough to undergo that kind of differentiation in the first place, so they're essentially an even mix of the starting materials available in the solar system. Even better, other asteroids are made of the cores of bodies that did form and start collecting heavy elements before being utterly obliterated, which means the whole asteroid is essentially made of heavy metals. The majority of this will be iron and nickel with a dash of cobalt, uranium will still be a tiny percentage despite being concentrated since it's just a rare element in our system, but the combination of the sheer volume of material, the high concentration of useful bulk metals, and the fact that a little uranium goes a long way means that it'll be a useful byproduct from normal mining operations. I'm not an astro-geologist, but I'd suspect planets and moons that had or have more interesting chemical / volcanic activity would be better places to hunt for ores, since odds are much higher they'd be able to churn and react things around, forming more concentrated ores like on earth.
You don't need iridium to make antiprotons, other natural mechanisms like cosmic rays produce them without it. If it turns out that iridium is crucial to mass manufacturing antiprotons, that's okay because while iridium is rare in earth's crust, it's much more common in asteroids to the point that a global sediment layer rich in iridium is how we figured out an asteroid wiped out the dinosaurs. The limiting factor is more than likely just going to be power for your accelerators and traps.
As for lofstrom vs skyhooks, they actually compliment each other quite well. Skyhooks can't reach all the way down through earth's atmosphere, so you need a spaceplane in order to grab the end of the tether and catch a ride. In order to protect it from space debris, a lofstrom loop only goes 80% of the way to space, so anything launched into space by one would be on an elliptical orbit with a perigee at whatever altitude the loop sits at, and would need another little push at apogee to put it in a proper circular orbit. A skyhook is perfectly happy dipping down to lofstrom altitudes and nabbing a payload, plus because the loop is doing most of the accelerating work, maintaining the hook's trajectory would be easier. Overall, loop + hooks is basically peak highway to space material.

Jen GentlemanWhat's a feature you use a lot on your PC that you think other people probably don't know about?

@chickfilla You don't need antihydrogen, you only need the antiprotons for this to work since it either relies on blowing heavy nuclei apart, releasing way more neutrons than ordinary fission per atom in the case of fission or just the energy output of the annihilation for fusion. Normal magnetic containment will work, since antiprotons are charged.
Nuclear pulsed propulsion isn't a new idea, it just hasn't been pursued because SOME people think mass producing low-yield nuclear bombs is a BAD idea. This addresses that problem by eliminating the need to use bombs at all, the antiprotons force something that ordinarily would never be able to go critical to go strongly prompt critical. You need way less antimatter than a normal antimatter drive for it to work, you're able to use much smaller pulses helping even out acceleration, and the engine performance is still really good. It's still definitely a drive you'd only ever use in vacuum, using one of these to launch from earth would be disastrous, but for things like rapid interplanetary transits or sending things interstellar it wouldn't be a bad choice.
I never liked the use of the term "catalyzed" for these reactions, I don't think it fits. While the antiprotons are helping the reaction, they are being consumed, which a catalyst typically isn't. "Initiated" or "driven" or "ignited" work better.
While this is all fine, really this engine is something that only becomes useful once you have enough infrastructure in space to want better ways of quickly sending things between planets. In the near term, the main bottleneck is sending things between earth and earth orbit, so I think billionaires should waste money on a lofstrom loop instead.

Introducing: Toste, a burly, sturdy 1.21 megawatt nuclear derg built to withstand any planet or moon in the system.
I made the comic a while ago- looking back, it might be fun to continue as a colony slice of life thing. I may do that at some point
