  • I’ve been having trouble with this too.

    So far my best assessment is that the problem stems from the Chromecast not playing well with my router. Resetting the Wi-Fi on my router tends to fix the problem, but it’s seriously annoying.

    Separately, I also have issues with the play/pause not working when casting and some other weird interface behaviors sometimes. But all in all, it’s worth complaining, but it still works better than everything else.

    Water from non-Earth sources might contain dissolved minerals at poisonous levels for agriculture, much less human consumption.

    Oh yeah, it’s practically guaranteed to contain nasty stuff! We’re gonna drink it anyway though.

    Most of that water on earth that we’d consider “not useful” would fall into the “100% useful” category if found in space. As long as the contaminants have a different boiling temperature from water, you can always boil the water into steam in order to separate it. Or you could also use electrolysis to separate out the hydrogen and oxygen and then recombine then in clean tanks.

    These are expensive methods of purification, energy intensive, but solar panels really well with no atmosphere and 24/7 sun exposure, so this is all feasible.


  • Why isn’t it targeted at the entire fanbase?

    Is that a serious question? Because the answer is obvious…

    Ok, let me start out by saying I have an 8 year old, and he fucking loves Minecraft. And hey, I played the game a bunch back when it was in beta and I was like 25. But I did not love the game the way that he loves the game… He’s obsessive about Minecraft, some days it’s all he talks about. How many adults do you know like that?

    And here’s the real question, when’s the last time you bought Minecraft merch for yourself? Because my kid has a Minecraft lunchbox, a Minecraft hoody, a Minecraft Lego set, some Minecraft figurines, and of course the Minecraft sheets and PJs.






  • Are you joking? Well the answer is no, no the SLS is about 40 years behind as far as technology goes. It’s basically a shuttle derived launch vehicle, the boosters are similar to the shuttle side boosters and it uses 4 slightly updated RS-25s (the space shuttle main engines) in the center stage.

    Except instead of getting with the times and attempting some reusability, it actually has less reusability than the shuttle had. They actually throw away all of those expensive high performance hydrolox engines on every launch.

    Entirely possible. But hey, in a space station you could have a separate agriculture ring, it may turn out that plants grow most efficiently at some particular amount of gravity, having its own ring would let you experiment, to maximize yield. Also you can use shades and mirrors to precisely control the amount of sun the plants get, even provide them constant sun if that speeds up growth.

    That’s true. Local water, even as trace ice crystals, would be easier to harvest than chipping apart a comet in deep zero g. But ultimately, your materials for both construction and life support are going to have to start coming from space, and asteroids and comets are the obvious choice.

    The best strategy would probably be to send a relatively small vehicle to the comet (small relative to the comet), something like the power and propulsion core for the new lunar gateway, essentially just a big ion thruster with a bunch of solar panels. This can push the comet into an orbit that swings it by the moon to capture it into an earth orbit. You may need to do some earth flybys to lower the comet’s orbit first, so the mission could take years. But to make up for that, comets are huge, and after it’s done you have a source of many different materials to work with right here in earth orbit, enough material to last decades or more.
