    It’ll take a lot of Delta V to get the whole country up there but might be worthwhile

      The funny thing about deltav is that it’s the same amount required even if it’s something huge like that. The fuel needed to make the deltav changes but the actual change in velocity is the same no matter what you’re moving.

        It’s still crazy to me that it’s easier to fling something out of the solar system along the plane of solar rotation, than it is to get something above the poles of the sun. I understand why that is mathematically and physically. Still doesn’t seem like it should work that way.

          probably because the sun is so massive, and the heat, gravitational, solar flares would likely make that difficult.

            Apparently it’s more because of inertia and the rotational spin of The Sun affecting the entire solar system, than anything else. Which actually makes me wonder if Voager and Voyager II will have issues once they fully pass beyond the heliopause.

            Apparently our star, and therefore the rest of the solar system, moves around the galactic disc in the direction of galactic spin, but it wobbles “up and down”, as well as possibly “left and right” as it orbits the galactic center every 225 million years, or so.

            The reason that Voyager, Voyager II, and pretty much every single other probe we send outwards might have some issues once they pass the heliopause is that our solar system is a bit tilted compared to the galactic plane of rotation. They may encounter some background inertia that we didn’t account for.

            You may want to look at how we did the Ulysses probe, by using Jupiter as a gravitational slingshot at about 80° relative to the solar plane of rotation, or the Solar Orbiter probe that is set to use The Sun as its gravitation slingshot when it reaches perigee. Thereby using the least amount of fuel possible, and turbocharging the eventual later deployment of solar sails.

              I mean those are really cool, but I gotta get past mun dudes.

              Did I mention how much I suck at ksp? There are not enough struts for my skill level. I recall enjoying building probes and then losing contact with them last time I played.

                I find that when I’m sucking at KSP, going and playing Factorio or Dyson Sphere Program seems to help with my return to KSP.

                Oh, and I’m a singular dude, not plural.

                Also, it is counterintuitive, but it’s actually easier to get to Mars, rather than Mun. You need a lot less fuel because you can use atmospheric braking.

                  Oh sorry about the plural. A little higher than usual and projecting I guess, or a typo or something.

                  That is a good tip. I’m mostly just fucking around with the tech tree and trying to play the game as intended non-sandbox. But then I blow up something I worked too hard on, get frustrated, save, set all my probes to hit kerbal home base in a flurry of destruction and go play no man’s sky where I only blow up when I want to

          on a side note, it takes less fuel to transport stuff to the surface of mars, than to the surface of moon. the reason is because on mars you can aerobrake while on moon you have to spend fuel to decelerate.

          1967 - They say, the design was accidental, for sure, I think, maybe a Freudian lapsus

            I can believe the design is accidental (an L makes a wonderful and easy building shape and four of them make a square. NO NOT THOSE FOUR basically) but it is right on the edge of reasonable doubt. Like, I haven’t just visited San Diego, I spent a month there couch surfing at my friend the elephant trainer’s during a brief residency. Maybe it’s a northern/southern California rivalry bullshit thing, but San Diego feels… weird. Not good weird. It felt like it was more influenced by the desert and Phoenix than by the ocean and Mexico. The personality of the city just didn’t fit. And that building fits perfectly in that incongruity.
