  1. Hello folks, so I'd like to show my worldbuilding project + a planetary system I'd like to eventually incorporate into it. It takes place in the 27th century and is reasonably hard SF, but not "diamond hard". It's a work in progress and the general technological level is advanced fusion/early antimatter drives, strong but not transsapient AI, extensive human genetic tweaking for different conditions is used etc. I'd like to hear some feedback, ask me questions etc. For the reasons of lenght I present it as Dropbox links, keep in mind you don't need to be a Dropbox user or have it installed at all to take a look on it (.rtf is the WordPad format btw). Some pictures of the Ra/Satis planetary system: EDIT - I'm not sure this is the right subforum for this but I don't know where else to put it. I'd like to ask admins to please move it to the approperiate section if this isn't the right one.

  3. The future of Kerbin is in your hands... "The Time Machine" Get it here before time runs out. Created in Kerbal Space Program 1.8.1 with 136 parts. Breaking Ground DLC : Surface Mounted Lights : TweakScale : Textures Unlimited : Textures Unlimited Recolor Depot
  4. A faithful yet somewhat psychopathic sentient robot, Maximilian was the servant and enforcer for Dr. Hans Reinhardt on board the doomed deep space science vessel "Cygnus." Maximilian is capable of deploying fully functional spinning blades and comes with three pairs of fully articulated arms on rotating shoulder joints. Eight tons and 268 parts requires Breaking Ground DLC, and TweakScale, with Textures Unlimited and Textures Unlimited Recolor Depot for custom coloring. Availabe on KerbalX
  5. The Matrix, Sentinel (an HvP sci-fi replica) At only ten tons and 1630 parts, this "Sentinel" drone is the perfect search-and-destroy machine. If you have certain subversive biological elements that fail to integrate into your virtual reality matrix these intelligent and highly efficient living machines will ruthlessly carry out infiltration and elimination missions in the "real world."* *the real world is assumed to be the planet Kerbin, its stellar system, and associated planetary bodies. Not liable for failure to operate in a higher order reality if Kerbin is found to itself be code in a computer generated virtual reality. In addition to the Making History DLC, and (excessive) use of Tweakscale, coloring and textures are provided by Textures Unlimited and Textures Unlimited Recolor Depot. Recommend deploying only in ½ Kerbin gravity. Moderate use of autostruts secure the tentacle ends to root of craft. It stands on its own, but is still very unstable - be patient. Craft is in a fixed state and cannot be moved without Vessel Mover or like mod.
  6. When you wish upon a star Makes no difference who you are Anything your heart desires Will come to you... -------------------------------------------- 58 tons and 1176 parts, almost half of them could be lights but I wouldn't hazard a guess on the number. Mods used are heavy use of Tweakscale, Aviation Lights, Surface Mounted Lights, and for camera effects Scatterer, and KS3P with the camera bloom effect turned up. Direct screen captures from in game, no photoshop used.
  7. This report/analysis seeks to answer the question: What would the future of the Kerbals look like? Specifically in the time frame of say, 100-300 years, a future firmly ingrained in realism and hard Sci-Fi.. I’ve had the idea of creating a story set in that approximate era, but being an extraordinarily extravagant idea, this series is dedicated to finding out the specifics. I also hope that this series will help future writers help flesh out their futuristic universes as well. Things to Note: -There’s a fair amount of mods used in this series—but i’ll try to keep it at minimum -Nothing too implausible will be used (no warp drives, but certainly nuclear fusion) -If you’ve got an idea for a chapter, let me know! -Want to contribute directly to the project? Come to the ToughSciFi discord, where this series has a channel for itself. -It helps to read the comments, since some bring up some good points -When writing these chapters, I do tend to assume that kerbals have a similar physiology to humans... But greener and smaller? -The goal of this series? Consider all the essentials for world building a futuristic Kerbol System -For engines I try to mix info from the game and real life, but the pros and cons, as well as the uses sections generally reflect the in-game depiction of the engine -Since I have both near Near Future Electric and KSP-I installed, a modifier lowers the output of KSP-I stuff* *I later chose to just work with the power output in KSP-Interstellar, so I amended most of the chapters to reflect this Table of Contents PROPULSION Chapter I—Atmospheric Propulsion Chapter II—Electric Propulsion Chapter III—Nuclear Propulsion Chapter IV—Fusion Propulsion Chapter V—Mixing Propulsion Systems Chapter VI—Beamed Power THE PROCESS OF COLONIZATION Chapter VII—Colonizing Moho Chapter VIII—Colonizing Eve a.

Chapter I: Atmospheric Propulsion "It’s a bird! It’s a plane! No, it’s a nuclear-powered hypersonic ramjet airliner!"-Linus Kerman A hypersonic, heavily-modified concept version of the Stearwing A300 that utilizes nuclear ramjets Perhaps we should start with something that is readily available to kerbals—flight. With jet fueled engines it is possible to reach speeds of over Mach 5. While that is excellent, major problems arise from its use—large portions of the plane are reserved for fuel, not passenger space, and a large amount of funds are used on fuel. Preferably there should be a way to reach those speeds without fuel... A conventional 16-passenger hypersonic aircraft, almost half of its takeoff mass was dedicated to fuel. The main focus of this chapter is thus about finding new ways of (supersonic) aviation. The way in question (with the mods available) is the powerful nuclear jet, generally produced in two varieties; turbojet and ramjet. On Kerbin they achieve speeds similar to that of the liquid fuel jet planes, with higher thrust. They perform exceptionally well on all atmospheric bodies, with tests on Duna achieving orbital velocity. Without the need to load fuel, planes could be lighter and take less time to be able to fly. A basic fighter design that can reach hypersonic speeds and reach space on Eve. Such designs could easily outmaneuver jet fuel enemies, but you probably don't want a nuclear jet flying over your own territory... Duna, where nuclear ramjets achieved an apoapsis of ~5000 km Disadvantages Sadly, this is where we must look at the disadvantages. There’s one obvious one—the radiation hazards. Shielding (though we must take in the "future tech" factor) would be very heavy, and of course nobody would want to sit next to a nuclear reactor (10% flight ticket discount for sitting next to it?).That said, they could still be used on special SSTO launches in certain areas. Second, they would be expensive (likely initially and maybe for maintenance), which would make their flights high-priced but also keeps them from being used for missiles (Well, except for the fact that the TORY ramjet part is based off a supersonic nuclear bomb delivery method called Project Pluto...). A 64-Passenger concept aircraft that would use nuclear jets, with a conventional rocket thruster to reach orbit, at which point it can safely return with a powered landing. Provided enough shielding is given, they could be practically everywhere in locations with poor infrastructures and no alternatives, a fate likely for the planet Eve. How Would I Use This In a Story? As a method of getting around on planets, and the best part is that you can actually make the plane in game, so you don't have to resort to pure prose or drawings. As for part of the story, I'm not exactly sure what they might be used in, but perhaps a radioactive crash involving such a plane could have be a plot point... End of Chapter One: Atmospheric Propulsion Next Time: Spacecraft Propulsion (Electric) Thanks for reading!

  9. Hello, everyone! You all probably don't know, but I am usually bad at writing stories. I can think of lots of ideas, only for them to end up bad on paper. However, this story is an original that I am proud with., since it is rather unique, and the first one that has more than 3000 words per chapter. ————————————————————————————————————————————————————————————————————————————————————— Read it here: Planned number of chapters: 20-30 Current amount: 1

  11. I may potentially create another version of this craft with a more functional cargo bay (or passenger cabin as it's referred to in the video) that can contain an SRV or probe. Suggestions are always welcome, thanks!
  12. Here's some images of my last hurrah with the Flying Tiger port of KSP, figured it was fitting to share those here, and the night before the new release... It's a lot of images, but I thought the ship was just a really cool way to end off some good... and bad memories... (not to brag, but the game only froze 3 times during creation)
  13. THE UNCATCHABLE SWIFT "Like the NTR did for Duna Exploration, the Uncatchable Swift does for Interplanetary Transportation" Powered by an Inertial Confinement Fusion rocket, the Uncatchable Swift can reach Duna in 10 days, and Jool in as little as 55. Packed with 175 km/s of delta-V, no longer are you restricted by Hohmann transfer windows—just point towards the target and burn! As a holiday gift to all kerbals, now available for download! This ship was created as part of the Imagining a Kerbal Future series, in the two chapters where I designed a futuristic spacecraft. The first part can be found here, the second here. Purpose While mass drivers have taken over the role of launching unkerballed cargo, a much more comfortable ride is needed for a Kerbal. Therefore, this vessel is intended to give kerbals the comfortable trip they deserve. Not only is this an incredibly quick ship, it can operate inside planetary systems without the use of tugs, a fate that befell many low-thrust fusion drives before this one. Though in-game you can't load a thousand kerbals on board, I derived numbers from the Kerbalism mod to create a space and mass required for that number of kerbals, so you probably could load a thousand kerbals onboard. Features The Uncatchable Swift is equipped with two large centrifugal arms that if spun up (if Infernal Robotics parts are added to the ship) should create artificial gravity for the occupants. I tried to make this a realistic design, so I added tapered radiators and fuel tanks to fit inside a "radiation shadow" created by a shield, and that is also why a huge truss segment was built, so the arms could fit inside the cone. The powerful engine is built so that the Isp can be sacrificed for thrust, and vice-versa. Warnings As the ship is based in a futuristic setting, it assumes that the whole ship was not lifted from Kerbin, and was instead built with parts built in space. Therefore, you will need to place the ship into orbit with the cheat menu or Hyperedit. I personally pick Kerbostationary, since I would assume many space stations would be located there, since space elevators could be built there. A bug I noticed with this ship also means that an amount of Deuterium, Tritium, and Hydrogen much higher than there is supposed to be sometimes gets loaded onto the ship. To fix that, either do so in the VAB or with Hyperedit menu where the level of resources can be edited. Once complete, this ship should be ready for operation.

  14. I recently saw a post by @goduranus showcasing their way of replicating the (admittedly overpowered) fictional fusion rocket engine from the sci-fi series The Expanse, the "Epstein Drive". This propulsion system, invented in the series' backstory by a Martian drive engineer named Solomon Epstein is a unique way to tackle the "torch ship" concept- a very high TWR fusion rocket engine with near-fantastical levels of delta-V and fuel efficiency allowing for long 1G or higher thrust burns, created as a stroke of dumb (and ultimately fatal) luck by a man tinkering with his personal spacecraft. Now, with the capability to make Epstein Drive-propelled craft in KSP, I figured I'd tackle a replica of Mr. Epstein's infamous ship, his personal space yacht. As the Sun rises over Duna, Solomon Kerman preps his ship for launch on the first test of his newly modified drive system... ...Little does he know that he's about to make history. The ship utilizes a unique propulsion system, which features a group of spider engines (altered in the .craft file's values to have negative thrust % and thus mimic the high fuel efficiency and dV aspect of the Epstein Drive) and a single Vector (which mimics the high TWR and blue engine exhaust plume of the drive). This means that while you can indeed load it up in a vanilla, pure-stock game with no troubles, it is indeed "modded" in the context of having a tweaked craft file. However, this is only to accomplish the feat of replicating the insanely powerful features of the drive system without being forced to download or develop a custom part or part pack in order to do this. ^the speck in the background is Duna falling away! Internally, there's space for up to 4 Kerbals, which can be transferred to other vessels via a docking port on the underside of the bow- docking is possible thanks to multiple RCS blocks across the ship's structure. For reference, here is an image of this very same ship in the TV show, from Season 2: Controls: The ship stages to activate the engine, and you can press 4 to extend the radial antenna array (the larger one on the front section is manually raised). Light on/off toggling will not shut off the blue glow in the drive cone area. DOWNLOAD HERE! Hopefully other fans of the show and books will enjoy this ship as much as I have while making and testing it. If I can find the time and motivation, perhaps I'll use the same setup to make a Rocinante replica fitted with BDArmory vulcan turrets as PDCs...
  15. We've all seen and read them, so why not share them! I'm sure that you have some copies of sci-fi comics lying around somewhere, or have been inspired by them at some point, and you're not alone (I was five after reading a Star Wars comic, and put myself in a cardboard box, trying to be a Star Destroyer). Besides, it's fun to see what they imagined what we'd have in the 21st century (hovercars, rayguns), and what we actually have (rising tensions between countries, threats of nuclear war, etc). So if you've seen some old sci-fi comics around, then why not tell me about them!

  18. The Chase (that I cut to because all my original progress for this thread was wiped due to a forums derp): The mod would revolve around the addition of a new, universal atmosphere that extends beyond the planets into space. Let's call this new atmosphere "Ether" for the purposes of this post. Ether has two unique properties; only parts with a specific tag can interact with it aerodynamically, meaning that your mega space station's orbit remains untouched, and that it exists everywhere, including planet surfaces. Now with the proper parts, you can use Ether to literally soar through the stars and to planets that previously needed a working knowledge of orbital mechanics to reach! Said parts could include a BD Armory-esque tag that makes the whole craft susceptible to the influence of The Dark Sid- *cough* *cough* I mean, er, Ether, or specialized wing pieces specifically engineered to use Ether in order to generate lift and drag. Of course, other locomotive options would exist in order to truly emulate your favorite Star Trek episode. Warp Drives, Ether-powered VTOL engines/RCS, even main engines would be available for easier maneuvering around the stars. Quantum Anchors for sci fi stations/outposts could lock the vessel's position relative to the sphere of influence they happen to be in. Constructive criticism is welcome (including people stating that this mod is impossible due to various game engine constraints)
  19. So I was thinking How about a mod that adds a Fusion engine, hydrogen Tanks, Exotic Matter engine, Exotic Matter Tanks, And a Exotic Matter Generator. So the fusion engine needs to have a lot of thrust and have a lot of Isp in it. It will use like 1.2 Units of Hydrogen. And the hydrogen is going to be a to be well light and like Xenon Gas so a lot of it in a tiny sized tank. And Exotic Matter engine is going to have a like 5X as much as the Fusion Engine, And not a lot of Isp. Some what like 0.5 As much as the Fusion engine's Isp. Exotic Matter is going to be heavy So something like 15 kg per Unit of it. And super dense so it will have a Ton of it in a tiny sized tank for Example a tiny sized tank would have 8,000 units of Exotic Matter. So the full mass of the engine is 120,000 kg. And the Exotic Matter generator will use 50 Electric Charge/sec to make 1 Unit of Exotic Matter. And Exotic matter is maybe what a black hole is made up of. But this is super charged Exotic matter so it will be unstable. So if it gets Zapped by anything it will explode. And what I would like if there is a Fuel tank for each Size in the game so they are tiny, small, large, extra large, Mk2, And Mk3. Can any one make a mod like that. If you do can you send a link of it to me?
  20. There was a book series I read when I was younger called Pendragon. One of the books took place on an Earth-like world called Eelong which, instead of a normal sun, had a bright band (called a "sunbelt") that stretched from the northern horizon to the southern one, and still had a normal day/night cycle. Obviously it's not hard sci-fi, but I was wondering if something like that could actually exist in the real world somewhere. Perhaps the planet orbits a pulsar, and the sunbelt is the bright beam of radiation that constantly spews from its poles. Is there are scientific basis to this? Any place I could experiment with the concept?
  21. In Dusker, you are a survivor on a derelict ship with no recollection of what happened. Pretty normal sci-fi game so far right? But what makes this game different is that you are not a space marine, or space miner, or whatever hands on job they tend to put you into. Instead, you are a salvage drone operator. Your interface is mostly based on what you have on the drones - camera, motion sensors, probes, all of which can be damaged and failed while you have to adapt - and most uniquely, you control all your drones using text commands only! If you ever enjoy those hacking game where you rapid fire commands on keyboard, you will find the feeling here, only even more exciting:
  22. I've got quite a bit in my collection, but I've read and re-read the good ones. I'm looking for some fresh pages! Here are some of my recos (some are not entirely sci-fi, but who's splitting hairs?): Jack McDevitt, the Academy series and Alex Benedict series, and some of his standalone books William C. Dietz, the Legion series and Sauron duology Harry Turtledove, the Worldwar/Colonization series, the Days of Infamy duology, and Guns of the South Larry Niven, et. al., the Man-Kzin Wars series Stephen R. Donaldson, The Gap series Jim Butcher, The Dresden Files series Stephen King, The Dark Tower series Whatchoo got?
  23. So since my other thread got a lot of discussion about how aquatic alien came to be, and how they are able to develop technology, which I am interested in, but since it is off topic for that thread (which concerned more on their spacecraft design than how they get those spacecraft), I decide to make this thread. The main topic of this thread then, is to imagine possible scenarios where aliens from an aquatic world evolved to be intelligent and develop the technology to create space craft. Conditions are simple: 1. Their world has no dry land mass 2. The alien will likely, at least in the beginning of their evolution, breath in liquid The composition of their world, their star system, the ecology, and so on, will be left to your imagination. What are the conditions required for intelligent aquatic life capable of space tech? Let's imagine.
  24. If you have read Asimov's "The Last Question" you probably remember that the Universal AC, in its quest to reverse entropy, grows to this size and larger. And in another lesser known sci-fi trilogy, "A Requiem for Homo Sapiens", one of the central themes is the human ascendance to Godhood through uploading one's mind to galaxy-sized computers made of clouds of nanomachine connecting to each other, ever expanding, with computing power so powerful that you can simulate realities indistinguishable from the real thing in any aspects imaginable. So setting aside post-singularity technology that our mind can't even begin to comprehend, say if we are given a galaxy sized computer (by an alien race, perhaps?) with the current processing power multiply to galaxy scale, what can we do with all of that?
  25. Subtitle: or, everything that will go wrong when you freeze time. ----- So recently we got a new gimmicky third person shooter game called Quantum Break, where the main character can manipulate time to do some fancy tricks. Most notably it has areas where time stops completely, or playing itself in a loop and our character can use the environmental objects trapped in time to advantage by releasing a frozen object to play in the loop or freezing an object mid loop, such as releasing a frozen car mid crash so it flies into enemies, or freezing something looping around in mid air to be used as foot hold to travel around. Now that's enough about the game, I only mention it because that game reminds me of something I have always wonder about the time stop situation, in that, how physics works in such an environment. Of course this has no bearing on the real world that we know of, but it is fun to think about scenarios. Ignoring why or how time suddenly stop, I wonder what happens when, say, a person is capable of moving around freely in such an environment. What happens to light, for example. If time stops, suddenly, all photons in the air will be suspended as well. How would a time traveller in such environment see? They would only be able to see as long as they move forward, but as soon as they move backward, no light will hit their eyes and suddenly the whole world is black for them. And then air as well, if no air molecules enter their lungs because they all freeze up, the time traveller would be choking right where they stand, and thus must be running to catch all the air they could. And then I wonder about forces such as momentum works. Does the time traveller impart force on objects suspended in time? Will there be inertia? What happen, if say, the time traveller takes an object, and push it for a distance, and then time resume? Would all the momentum builds up in the object be released all at once? Also compression. If all the atoms in the air is frozen in time, would the time traveller, by merely moving, compress them together to the point of fusion, because they are essentially moving faster than light? Every movement would trigger catastrophic explosion as soon as time resumes, wouldn't it? I am sure there are more things that might go wrong in this time stop scenario, but I don't have enough physics knowledge. Any of you have other ideas?
