iN THEORY, WE HAVE MATHEMATICALLY PERFECT CRYSTALS, AND A SCREW-HATCH CAN GET A PRETTY DECENT PROGRESSIVE SEAL, caps lock can be a nuisance, temperature-control is a thing that we can do, so thermal deformation can be mitigated. In practise? Seals are really difficult to get right. We don't have rubbers of any kind and trying to compress crystals is just asking for disaster. If we didn't have mathematically perfect crystals and thermal control, then I would say that it is basically impossible, we could play with leather pads or something, but no. With them? Ehh, I would say that it is an added difficulty and complication, more reason why it is far too much for a single action, but probably theoretically possible. Since it is not actually loading and firing a cannon anymore, it is plausible that the crew cabin could be permanently sealed, so that is a plus...
Agreed on the oxygen. There is some theory that we have temperature regulation circuits that just directly fix the temperature, and that, combined with a spell that produces gasses, equals a spell that can fix the ambient gas composition to something breathable without converting the crew into gas(which would probably have utility as an effect...) or creating new gas, it just changes the existing gas. I figure that they actually operate spells and adjust them as needed, which would mean that we would be using a brand-new air creations spells and a completely unprecedented air destruction spell to counter it, that were each targeting specific aspect of the air rather than the "hotter or colder" of the temperature circuits, but that is an assumption on my end. I also figure that we don't have anywhere near the expertise with gasses to pull it off even if we did have an air-composition-fixing circuit. But again, this is all assumptions on my part. If it works as intended, then it just magically keeps the air at breathable levels directly. I feel that to be an extremely big if, but I may be in the minority there. So I put this one in the "impossible to pull off, even if we devoted a whole design to it, but theoretically works otherwise" category, based entirely upon my own assumptions, and I have been very wrong about what we can achieve before.
First telescope ever and it spots buildings from space, agree that it is overly ambitious even with mathematically-perfect crystals. Also we have no way to know where "down" is, so figuring out if you are looking at the spot directly beneath you, or the spot a dozen kilometres to the right of it, is not really possible. And they have constant storms from what I can tell, that include clouds, so, like, probably an order with a hefty bonus to remove it and a high chance of random bad weather getting in the way. but it could work if we roll really well...
continuing the previous into the following. They are not actually orbiting. Due to unlimited fuel they will just be loitering. Probably still needing to maintain a pretty high speed to maintain position relative to the ground, but much less than orbital velocities. And the crystals are indeed tough, so it seems viable? And apparently weightite is supposed to be a crystal now, a super dense one? When crystals are basically all about complex structures that kind of inhibit insane densities? I figure that it will be lucky if it breaches ten grams per mil, but whatever, a big enough lump ought to hurt, and will probably keep together due to not actually being at full orbital velocities.
Of course, the whole "not orbital velocities" thing does have its flaws. Due to inertia and surface area, a certain amount of speed will be required, but geosynchronous low-loiter should be much slower than orbit.
The enemy just build gauss guns and can control air along with levitation magic. I imagine that they can get to space easier than we can.
Of course, this all assumes that magic works at all in space. It could be that magic is generated at ground level and once you get out of the denser atmosphere you are stuck with the magic that you can carry with you. Which would actually benefit us, especially if we refined our dedicated batteries, but would still be a brute on space missions and could be something that E.S. would pull to keep us going too crazy with lunar colonisation.
But then, maybe moon magic is different to WandRWorld magic, so we could get a whole new set of spells for the satellite wars...
I would vote and add the other optiuons and reind folk that apparently we can vote for as many different things as we want, but my broser is dying and I can't be bothered restarting it and coming back for all this, so good luck! Imma Just vote for whatever LightForger wants...
