    I'll pull the plug and start a fresh simulation.

    In huge quantities, cost is just another engineering problem, which needs to be solved once.

    Its actually a good match, you can almost do it with awk. Out parameters and named parameters are two problems I can think of. It does result in a lot of awful java code though,

    Not really. Its a fringe thing now. At a previous place I worked Ada was being auto-translated to java.

    If if it crashes

    Case in point, semantic analysis is available in some text editors to point out your mistake. A programming language which doesn't require that the programmer state their intentions makes it hard for silly mistakes to be identified early.

    Every programming language I have used commercially has had a few things it does well and a whole bunch of limitations. Bad code gets written all the time to work around language limitations. Consider the lack of data type declarations in python, java script, coffeescript, etc. Terrible for code readability.

    Its all religious theory and habit with very little up front thought and design. RIP Pascal and Ada.

    But uncrewed solar electric barges are well validated technology. There is one orbiting Ceres right now. With a top up of reaction mass it could keep going for decades.

    Well okay but its better overall than liquid fuels and if you want to send a pipeline of supplies to mars, its a good way to do that, while inefficent fast cruise stages take the humans.

    Voyagers 1&2 are closing in on 40 years, and only their limited power supply will force them to shut down. Granted running an engine that long is likely to be significantly more complex than other instruments.

    Totally incomparable. My multimeter is as old as my long dead first car.

    The big problem with fission -> electric -> ion drive is that your fission reactor needs a cold sink which can absorb its entire power output. To do that you will need a lot of radiating surfaces and associated plumbing. It adds up to a lot of mass, perhaps more than the reactor and shielding.

    The problem with all of them is the nasty equation KE = 1/2 m * V^2. That means the higher the exhaust velocity (and thus specific impulse which is the fuel efficiency), energy required goes up with the square of exhaust velocity.

    But thats just your input electrical energy being turned into kinetic energy of the reaction mass, and ultimately the vehicle.The more energy you pile on at that point, the more velocity change you get.

    Use an induction catapult to fire a stream of metallic reaction mass at your chosen target. Then send a second induction catapult along that stream, carrying passengers, flying to the target. Most of the work is done in the originating system. Your pellets reaction mass are self guided with microcontrollers and little ion drives so they can stay aligned.

    I expect momentum to be transferred in the direction of the impactor, not perpendicular to that direction, chewing up structure along the way. This structure was too stiff.
