  • So what it’s really like is only having to do half the work?

    If it’s automating the interesting problem solving side of things and leaving just debugging code that one isn’t familiar with, I really don’t see value to humanity in such use cases. That’s really just making debugging more time consuming and removing the majority of fulfilling work in development (in ways that are likely harder to maintain and may be subject to future legal action for license violations). Better to let it do things that it actually does well and keep engaged programmers.










  • Definitely oversimplification and I don’t mean to understate the efforts, technology, engineering, and materials that went into the ISS. It’s incredible. My main point being just how simple the current state-of-the-art is compared to what would be needed for a sustainable orbital shipyard.

    We know how to assemble stuff in space, it’s just expensive.

    Indeed (ISS being a good example of this fact). The scope here though is beyond just assembly. Also, at minimum, manufacturing of shielding components would likely be necessary in order for such an undertaking to be feasible.


  • Yeah. I think that they are simplifying a bit. For practical purposes, for the foreseeable future, it is a “can’t be”. There is a lot of work and research that would be necessary to get an orbital shipyard in place. As someone else mentioned, the current state-of-the-art space station is effectively little more than rocket body segments with extras (solar panels, etc).

    It’s much easier for me to say “this is what we would need to do” than to actually do it. We have the technology to build a space station. We don’t currently have proven technologies to refine, cast, forge, and extrude metal in microgravity and hard vacuum. We don’t currently have proven technologies to manufacturer space craft out of components in microgravity and hard vacuum. And those are just a handful of the necessary things that we know - there are a bunch of unknown unknowns.

    So, technically, yes, it isn’t a “can’t be” but, at this time, it may as well be.


  • If you’re asking about the shielding, probably the mass required for materials that are generally used for radiation shielding. If the craft is built terrestrially, the amount of energy necessary to launch would be insurmountable with current chemical rockets.

    Now, if the craft were manufactured in space (and forming of the shielding materials were practical in low-G), the problematic materials could be shuttled up over time, making it a non-issue. This would, of course, also mean that the craft could not be used for re-entry and would require landing craft. And there’s all the logistics challenges (supplying air, etc). Probably though the direction that will be necessary for long-distance space craft.
