  • Some people are being a bit pedantic about not technically needing the internet for email, and that’s true, but the pedantry is hiding the fact that actually email is really cool in how it exists in whatever form we want it to be in! It can be transmitted over internet, or over bare TCP/IP, or even peer-to-peer. Most applications don’t take advantage of how versatile email really is.

    Of course, Micro$oft makes it rely on an always-on internet connection because it’s better for their bottom line.


  • It is the year 2,002,026.

    Humanity has conquered capitalism and moved off of Earth. Disease and accidental death have been eradicated. We’ve invented marvelous and miraculous technologies and used them to catapult ourselves to distant worlds.

    It’s an open question whether or not our descendants can rightly call themselves “human” anymore, and indeed some on far-flung planets do not.

    On the planet Seffi, which we call Kepler-725c, one of those human descendants watches the end of a two-dimensional audiovisual narrative, a recent fad on the planet. They aren’t watching it on a computer, per se, but on a holographic mesh device operating across a distributed cluster of nanomachines. The human descendant telepathically interfaced with it to launch the application and the narrative, and now xe marvels at how immersive and compelling the narrative was, despite being contained as it was within a two-dimensional non-interactive form.

    A list of people who contributed to the construction of the narrative concludes its display, and the holomesh reverts to a waiting state, displaying a simple black panel within a white frame. And within that black panel, a small, orange-and-white triangle sits, perfectly centered. The human descendant doesn’t know what it originally represented, and muses briefly about it before deactivating the holomesh and walking out of xeir home to enjoy the sunset beneath the purple-blue trees.

    Partially, yeah. Crewed spacecraft by necessity weigh significantly more than uncrewed, because life support is very heavy. But they also want to take that very heavy spacecraft further away from Earth than any crewed spacecraft has ever been before, which means they need to take a lot of fuel; yes, it’s a gravity-assisted free-return trajectory, but it still needs fuel for course corrections and other orbital dynamics. Plus, it’s a two-stage spacecraft, while the Saturn V was three-stage, so it’s got to carry a lot more dead weight a lot further than before.

    All of that together means they needed the most powerful rocket ever. The lander mission will almost certainly be even more powerful than that, because while it won’t need to go as far, it’ll be carrying another spacecraft.

    EDIT: Actually, to correct my last statement, potentially not! Turns out the current plan for Artemis IV is to send the lander on ahead and have it waiting in lunar orbit for the astronauts to get there. So potentially all of the Artemis missions could be launched on this same configuration of rocket.
