    False alarm. Turns out that the planet probably doesn't exist.

    Semiconductors. To produce microchips, you first produce a large monocrystaline ingot of Silicon, then slice it into wafers, and then etch the conductor paths into those, and then cut them up again into individual processors. The size of those wafers is limited by gravity, they'll break if they get too large. But if you could grow them in zero-g, you could make much larger wafers, and produce much larger batches of processors.

    Ceres has been stripped of its ice, and is now a dry rock. The ECLSS on Ceres isn't 100% air- and water tight, and water is probably also used to produce fuel for chemical thrusters.

    That's a bullseye if I've ever seen one! Robin Hood, hang your head in shame!

    No, the Epstein Drive is basically a particle accelerator-boosted Fusion drive.

    It was just a graduation project, I'm not even sure he ever released it.

    That's footage from a VR game. https://www.artstation.com/artwork/5v2NO

    If "we", or whatever "we" are by then, are still around in 5 billion years, then yes. Otherwise, nah.

    I dunno about era, but I think Fury, Black Hawk Down, and Full Metal Jacket were fairly accurate in how they portrayed war, though maybe not quite so historically accurate.

    Not quite. The reactor parts become low-level radioactive. You don't get any high level waste from Fusion reactors. The Neutrons are also used to breed more Tritium fuel, via lithium blankets around the reactor chamber.

    As far as I know, High-Bypass turbofans, that's the ones used by passenger aircraft, stop working at the speed of sound, Jet Fighters use low-bypass turbofans, or turbojets, and have specially shaped intakes, and intake flaps to slow down the incoming air. Jet Fighters still can't keep their top speed up for long without overheating the engines, though. Ramjets and Scramjets need to be moving at high speed, and supersonic speed respectively, to work.

    Water is one of the most common compounds in the universe, after Carbon Monoxide and Methane.

    Part of the Bimodal NTRs' power would be used to power cryo-cooling systems.

    Biosphere 2 failed primarily because they didn't let the concrete cure properly, leading to a severe shortage of oxygen. Something an active ECLSS would/should be able to compensate for.

    You can use algae, which don't require much space at all. And we're producing enough food for 13-15 billion people, it's a problem of distribution, not production.
  16. SargeRho
    We can produce Methane and Hydrogen, and also Oxygen, in bioreactors. Some types of algae produce a black sludge that can be used as a crude oil replacement/supplement, and basically dumped right into a refinery alongside regular crude. In principle, anything you can make from Oil, you can make from algae.

    Nature-worshippers might whack us for screwing up the environment. Food is also an option.
  18. SargeRho
    Yes, around the docking areas of large rotating space colonies. But elsewhere, it wouldn't make much sense.
  19. SargeRho
    There's a first for everything.

    Actually, I read that our radio "bleed" is undetectable after 2-3 light years, due to becoming indistinguishable from background noise. I'm not sure how much that applies to targeted transmissions though.

    You can see a ship from millions of kilometers away in space, using passive IR.
  22. SargeRho
    ? You don't use sats for guidance in space, you use stars, radio beacons and pulsars.
  23. SargeRho
    By rattling the barge, and by extension, the transmitters, messing up the signal.
  24. SargeRho
    The fins are probably spring-loaded for reliability reasons, just like the legs.

    If you don't want to make antimatter yourself, a gas giant's magnetic field is exactly the place to go to get some antimatter.
