  1. This is the KSPI-E support thread. For talk about new development and features request you have to be in the KSPI-E develpment thread KSP Interstellar Extended (KSPIE) is a plugin for Kerbal Space Program, designed to encourage bootstrapping toward ever more advanced levels of technology as well as utilizing In-Situ resources to expand the reach of Kerbal civilization. KSP Interstellar Extended aims to continue in Fractals original KSPI vision in providing a realistic road to the stars. Players will first gain access to contemporary technologies that have not been widely applied to real space programs such as nuclear reactors, electrical generators and thermal rockets. By continuing down the CTT tech tree and performing more research, these parts can be upgraded and later surpassed by novel new technologies such as fusion and even antimatter power. We attempt to portray both the tremendous power of these technologies as well as their drawbacks, including the tremendous difficulty of obtaining resources like antimatter and the difficulties associated with storing it safely. The goal being to reward players who develop advanced infrastructure on other planets with new, novel and powerful technologies capable of helping Kerbals explore planets in new and exciting ways. The principal goal of KSP Interstellar is to expand Kerbal Space Program with interesting technologies and to provide a logical and compelling technological progression beginning with technologies that could have been available in the 1970s/1980s, then technologies that could be available within the next few years, progressing to technologies that may not be available for many decades, all the way out to speculative technologies that are physically reasonably but may or may not ever be realizable in practice.

To help you get started, you can make use of the following resources: KSPI-E for Dummies KSPI-E Guide by Nansuchao KSPI-E Technical Guide KSPI-E Wiki KSPI-E Youtube Videos: 9 part Russian Tutorial by @ThirdOfSeven 3 part EnglishTurorial by @Aaron Also: Main Features KSPI Extended includes new improvements and fixes from which the following are the key features: Improved realism of diversity Nuclear Engines Electric Engines Reactors Thermal and Electric Propellant Fuel Modes for Fission, Fusion Beamed power transmission Support KSPI-E add support for the following mods Basics KSPI-E Construction There are 6 basic components needed to create a working KSPI-E propulsion module are as follow Reactor - A reactor is needed to produce heat energy or charged particles which is used by other KSPI components to convert it into useful energy. Pebble Bed is recommended for high thrust/atmospheric launches and Molten Salt is recommended for long term usage for upper stage/satellites. Your choices will change as you unlock more components Generator - A generator is required to produce Electric Charge and MegaJoules, both resources are needed on almost any KSPI vessel. Megajoules are needed for KSPI engines which have ‘Electric Power Needed’ = Yes or Partial Radiators - Radiators are required to expel WasteHeat from the reactor, generator or engines. Without a radiator you will not be able to generate any power! Engine - Without an engine this wouldn’t be much of a propulsion module. Most engines operate most effectively when directly connected to the reactor. The reactor heat transfer performance values will indicate how much of the original energy is available if an engine is not directly connected to the reactor. The Atilla and Arcjet RCS thrusters do not require any direct connection to function at 100%. I recommend starting with either the Thermal Turbojet or Thermal Rocket nozzle. Propellant/Fuel - All Reactors and most Engines require propellant/fuel to operate. The Interstellar Fuel tanks are the standard containers that will be used to store the propellants. Hydrazine or LqdAmmonia are performance fuels and are be strongly recommended for Launch stages. Control - A probe core or crewed command module is also needed to operate the vessel. Common Issues All engines (except vacuum plasma thruster) must overcome the static pressure in the atmosphere and is better suited for vacuum usage and may not show any thrust in the atmosphere. Smaller thrusters will help overcome static pressure Research KSPI Is a High tech, hard science mod which gradualy unlocks sophisiticed technologies with advanced research . When researching KSPI techs, your are not forced into following a single path. Instead there are mutliple paths you can focus on. Nuclear Propulsion is a stock tech but it unlocks the first Nuclear Engine, the Solid NCore Nuclear Engine a.k.a. NERVA. It intitialy can only use LiquidFuel or on Hydrogen as a propellant, but as more Nuclear Propulsion Technology is reseached it is capable of using a divere variation of propellants Nuclear Power unlocks the first reacor which is specificly ment for fission power production in space, the Molten Salt Reactor which contains a build in thermal electric generator Advanced Nuclear Power unlocks the the modular Thermal Electric Generator, which when connected to a reactor can produce electric power Advanceded Nuclear Propulsion allows the NERVA to function in LATERN mode, meaning adding exygin in the nozzle to increase thrust, and unlocks the Thermal Launch Nozzle which can be put under modular reactor High Energy Nuclear Power unlocks the Particle Bed Reactor, which is capable of generating high amount of thermal heat at a low reactor mass. THe High Trust to Weight ratio makes it suitable of beinged used as a heavy single stage to otbit, which is it's main intended purpose. Efficient Nuclear Propulsion introduces the Closed Cycle Gas Core Reactor which can achieve significantly higher Isp than the NERVA Experimental Nuclear Propulsion unlocks the Open Cycle Gas Core Reacor, which offers even higher ISP than the close cycle gas gore reactor but at the expanse of versatility as it is only capable of orating while in space. Exotic Nuclear Propulsion unlockes the Fission Fragment reactor, which thanks to its ncredible high Isp allow allow to the travel to anywhere in the solar system and behind. The reactor can also be used for High efficiency electric power production Fusion Power unlucks the First Reactors intended for power production, the Magnetic Confinement Fusion Reactor which used super powererfull magnetcs to contain a plasma at high temperatures. Although thesereactors are bulky, they have ability to contain charged particles which can directly converted into energy at high efficiencies or redirected to a magnetic nozzle for Insterstellar HIgh Isp. For smaller vessels, The Magnetic Target Fusion Reactor is a highly efficient heat engine, converting fusion fuel and lithium into thermal power. Fusion Propusion unlock the first fusion engine which are inteded for propusion. Advanced Fusion unlocks the second tier of fusion fuels and introduces 2 advanced fusion enginess, the Tokamak Fusion engine and the VISTA Inertial Fusion Engine. The Tokamak Fusion engine has an integrated magnetic nozzle which can use any single atom propellant at high Isp and the Vista offers High Isp with High thrust levels Nuclear Engine/Reactors The Core of KSPI are its engine/reactor, they make the magic happen. There are now 5 Fission engines and 5 Fission Reactors, 5 types of fusion reactor, and 2 eotic reactor each with the own characteristic behavior, excelling in a particular way (and therefore most fit for certain applications) Part Model Unlocking Technology Power Output (2.5m) Reactor/Engine Main Properties Description Nuclear Propulsion Improved Nuclear Propulsion Efficient Nuclear Propulsion Solid Core Nuclear Reactor is one of the first nuclear engine available capable of using nuclear energy for propulsion, allowing Isp roughly twice the Isp of Chemical rockets. It's thrust to weight using Liquid Hydrogen is initially too low for any launch except in the upper stages. With Advanced Nuclear Propulsion technology is becomes possible to operate in Liquid Oxygen augmented mode effectively tripping the thrust at the cost of 36% lower Isp. With the advent of higher Nuclear propulsion technologies, other propellant then Hydrogen become available as a possible propellant, which is more or less adventurous depending on the circumstances. Solid Core Reactor can also be used for High power production, but due to it's inability to replenish its fuel, has only limited endurance. Traveling Wave Reactor a.k.a. Candle reactor is a small reactor specificly targeted for small probes. The reactor function in many ways like a candle, where is slowly converts it fisionable material into energy. Nuclear power Improved Nuclear Power Nuclear Fuel Systems 0.444 GW 0.666 GW 1.00 GW Min Diameter: 0.625m Dry Mass (2.5m): 8 t Fuel Mass (2.5): 6 t Cost: 18k Molten Salt reactor is the first high thermal power nuclear reactor available KSPI-E, they excel in reliable long lifetime thermal power generation using Uranium. At the expanse of 50% power output it can burnup 99% of all uranium fuel. Besides Uranium it is also capable of using Thorium which generated more power but it durability is significantly lower. On the upside thorium is cheaper than Uranium and can be mined much more abundantly. Because its nuclear fuel is mixed constantly, gases like Xenon gas are not trapped but are extracted and can be used for other purposes. This reactor is also very suitable for Tritium breeding where lithium is converted into valuable Tritium. Another advantage is that the heat from the reactor can be transported effectively to other modules thanks to Molten Salt transport medium. High Nuclear Power Systems Experimental Nuclear Power Exotic Power 1.333 GW 2.00 GW 3.00 GW Pebble Bed reactors become available a bit later than Molter Salt reactor but thanks to their significantly lower mass they are the first nuclear reactor with can provide a Trust to Weight ratio higher as 1, meaning it can be used as first stage or second stage rocket engine. Although Pebble bed reactors are ideal for providing high thrust, when used for power generation, they suffer from heat throttling, meaning the reactor will automatically produce less heat output when heat is building up. Although reactor uses a transferable fuel source, due to is inefficient fuel usage, (most of the mass is not uranium), it is not efficient for long term power production Particle Bed Reactor aka TIMBERWIND is the a specialized type of the Pebblebed specialized in high trust propulsion Efficient Nuclear Propulsion Experimental Nuclear Propulsion Exotic Nuclear Propulsion Closed Cycle Gas Core reactors excel in generating average amounts thrust combined with with significantly Higher Isp compared to it Nuclear counterparts. This makes them ideal for short range planetary missions to like Duna and Eve. The Closed Cycle Gas Core reactor is one of the few High Isp engine reactors which is capable of operating in an atmosphere. With the help of some boosters, it can be used to launch into orbit from Kerbin. Experimental Nuclear Propulsion Exotic Nuclear Propulsion Open Cycle Gas Core reactor excel a generating high amount of thermal power at double the core temperatures the Closed Cycle predecessor with less mass. This is achieved my removing the walls that separate the propellant and the nuclear fuel. Although this allows much higher core temperatures, the disadvantage is the reactor cannot operate while under the influence of acceleration, which happens when it is either on he surface or when accelerating at high speed. Exotic Nuclear Propulsion Min Diameter: 3.75m Dry mass: 16 ton Cost: 400k Fission Fragment Reactor (a.k.a. Dusty Plasma) improves over Particle Bed Reactor. When they first become available, they are less powerful as particle bed reactor, but it's the first reactor capable of generating charged particles. The generated charged particles are efficiently transported on your vessel using magnetic confinements and can be used for either Very High Isp propulsion in magnetic nozzle or directly converted into energy with Direct Conversion Power Generator. Fusion Power Advanced Fusion Exotic Fusion Unified Field Theory Min Diameter: 5m Dry mass: 16 ton Cost: 600k Magnetic Confinement Fusion Reactor (a.k.a Tokamak) is one of the first Fusion Power reactor and comes available with Fusion Power. This reactor is Big and Bulky and require a fixed amount of power to operate but it can be used wide variety of operations. The amount of power required depends on the type of fusion and the number of researched fusion technology. MCF is most suitable for fuel efficient, thermal efficient power production. One of the big advantage of Fusion is that it's fuel can be very cheap, relatively easy to store and has only low radioactive waste product. The Fusions product themselves can be directly converted into electric power, which allows it to be very energy efficient. Advanced Fusion Exotic Fusion Unified Field Theory Min Diameter: 3.75 Dry mass: 16 ton Cost: 800k The Stellerator Fusion Reactor is in essence a magnetic confininement Fusion Reactor with a significant higher efficiency at the cost of higher mass. This makes it most suitable power salilites in fixed orbit that need to maximise power output. Fusion Power Advanced Fusion Exotic Fusion Unified Field Theory Diameter: 2.5m Dry Mass: 8 ton Cost: 180k Magnetized Target Fusion Reactor can be smaller than the MCF reactor, but it is limited to providing thermal power. This makes it ideal for build SSTO vessels which require large amount of thermal heat to generate thrust when connected with any thermal nozzle. It can also be used for Electric Power production, but it requires a large amount of radiator to be effective. Fusion Rocketry Advanced Fusion Exotic Fusion Magneto Inertial Confinement Reactor is the first fusion engine specifically meant for Direct High efficient propulsion. It cannot be used for power and It's not as efficient as electric propulsion but it produces minimal amount of wasteheat, which will reduce the overall mass of the vessel. Note that the propellant is limited to Lithium , which is required both for achieving fusion as converting the fusion power in effective propulsion. Advanced Fusion Exotic Fusion Unified Field Theory Colliding Beam Fusion Reactor is the first reactor capable and specialized if the generation of Electric power from Aneutronic fusion reactions.The reactor has an integrated charged particle direct energy converter, which allows up to 85% of aneutronic fusion energy to be converted into Electric power. Since the direct energy converter efficiency don't depend on temperature, you can run the radiators a lot hotter, meaning you need a lot less radiators then other reactor which depend on thermal electric power conversion. This means it will be ideal when used with Electric propulsion engines and does not require any heavy thermal electric generators. The downside is the Engine cannot be used with either thermal or magnetic nozzles. Antimatter Initiated Microfusion (AIM) reactor can deliver more power in a smaller package but only runs on exotic antimatter, helium3 and enriched uranium. The engine can be connected to either thermal nozzles or magnetic nozzles. Antimatter reactors versatile , expensive, and incredible powerful, the only real problem is collecting significant amount of Antimatter. They produce up to 80% Charged Particles which can be used by magnetic nozzle to create a large amount thrust an high Isp Quantum Singularity Reactor is the ultimate Mass to Power converter technology. It uses a microscopically sized black hole to accelerate light atoms into charged particles and heat. The charged particles fuse resulting in heavier atoms, which can be used for other purposes. The black hole event horizon also creates small amount of antimatter which can be used by antimatter reactors. The amount of produced power is variable, but the amount of required power to sustain black hole is constant and it has a minimum power level at which the black hole can be kept alive.

Generators in KSPI generate both electric charge and MegaJoules. Generators must be directly connected to a reactor to generate electricity and can only use power from one reactorGenerator at a time. Radiators are required by the Generator to expel WasteHeat and will not function without them. Thermal Generators - These generators convert thermal power from a reactor into electrical power and waste heat. Their efficiency determines what percentage of that thermal power is converted into electricity. The rest becomes waste heat. Typical thermal generators in space use closed cycleBrayton gas turbines. For traditional molten salt-based fission reactors, this type of generator gives a maximum theoretical efficiency of 31%. Upgrading the electric generators changes them from Brayton Cycle Turbines to a KTEC Solid State Generator heat engine with no moving parts - this ups the theoretical efficiency to 60%! Charged Particle Generators - This type of generator produces power directly from the use of charged particles which are created in great quantities by fusion reactors. Charged particle generators have much higher efficiencies than their thermal counterparts. These generators will produce varying amounts of power depending on the reactor and fuel modes used The Thermal Generator and Charged Particle generators can both be used at the same time on reactors that produce both charged particles and thermal power. This maximizes power potential and lower your utilization and therefore minimise WasteHeat production and reactor fuel consumption. Radiators Radiators are used in KSPI to expel excess WasteHeat from a vessel. WasteHeat is produced by reactors, generators, microwave receivers and will build up over time. Once WasteHeat builds up in a vessel to 95% capacity than reactors and microwave receivers will automatically power down. If WasteHeat is allowed to reach 100% then the parts may start being destroyed from too much heat. Non retractable solar panels are exempt from the WasteHeat mechanic. The Thermal Helper addon included with the KSPI installation can be used to estimate a reactor’s WasteHeat output. The values in the addon will dynamically update depending on the connected components. The Thermal helper is only accessible from the VAB/SPH.

Thermal Nozzle is the first engine available. They directly use the thermal heat generated by the reactor to heat-up propellant. The Advantage is that this is very efficient, as minimum amount of power is lost, and many propellants can be used. The disadvantage is that Isp, which is lower than other form of propulsion, it dependent and the core temperature of the reactor and used propellant. On the plus side many propellants can be used and thermal nozzles benefits for the energy released by decomposition when propellant are subjected to high temperature. This means propellant like Ammonia and Hydrazine give a significant bonus to thrust and Isp. Although it offers you you to use many resources as an propellant, it might be wise to avoid propellant that contain carbon, as they tend to to produce clog the heat eachanges with soot, which lowers your maximum thrust and causing overheating. For optimal efficiency, connect a thermal nozzle directly to an reactor, but if desired you can put other parts between the thermal nozzle and reactor at the cost of lower efficiency. Thermal Turbojet becomes available at the same time as thermal nozzle. Their advantage is that they allow high amount of propulsion, without any propellant, that is they use the air as an propellant. This means you can save a lot of mass on propellant. The downside is that it only function inside an atmosphere, on the plus side, this includes any atmosphere, even those without any oxygen. Do note that in order to travel fast though the atmosphere, you need precoolers to cool the compressed air to a temperature that prevent the turbojet from overheating. Arcjet are the first electric engines offered by Interstellar. Instead of thermal heat, they use electric power to heat a propellant to high temperature. The advantage is that you can use any non oxidizing propellants and enjoy the same decomposition propulsion bonus. One of the big disadvantage is that electric propulsion is less efficient as a lot of power is lost by converting the power into electric power and then convert into heat again. This is compensated by its ability control it's trust at the cost of Isp and the ability to use multiple reactors to power the same set of engines. Arjcets can be connected any where on you vessel, just make sure it is fed with desired propellant, and the reactor has access to radiator to lose its waste heat.

The technologies used in KSPI are based closely on real life engines or scientific theories. Note the distinction between Thermal and Magnetic. Thermal engines have limited Isp but benefit from thermal decomposition, giving it extra thrust and improved Isp. Magnetic engines first need to Ionize the propellant. Some engines like the Vasimr and Atilla engine use a combination of the 2 techniques. Method- This describes the engine's power input used to generate thrust. Engines can use Thermal (GW) power from a reactor, magnetic types use charged particles, quantum vacuum uses the vacuum of space to produce thrust and Fusion uses an internal fusion reaction to produce thrust. ISP (LqdHydrogen)- This section shows the ISP (fuel efficiency) an engine produces when using LqdHydrogen as the propellant. Different types of propellants can provide different thrust values in an engine which is covered in more detail the Propellants section. Efficiency - The efficiency of an engine is how much of the thermal power (GW) is used to produce thrust and the remainder is expunged as Waste Heat. A low efficiency engine may require additional radiators to radiate the heat into the surrounding environment. The efficiency of electric engines is highly dependant on the efficiency of the propellant used. Variable ISP - In KSPI some engines can have a variable ISP when operating. The ISP of an engine decreases as it produces more thrust. Higher thrust values also decrease the energy conversion efficiency. Gimbal - This describes if the engine has gimbal capability. Gimbaled engines can use thrust vectoring to control the attitude of a vessel. Note that RCS engines do not gimbal but are linked with KSP RCS system. Functions in Atmosphere - This is another self-describing value which explains if the engine can produce thrust when in an Atmosphere. Some engines rely on the vacuum of space or other methods to produce thrust and cannot be used in an Atmospheric environment. Many of the thrusters in KSPI are affected by static pressure. Which means the engine has to overcome the pressure of the atmosphere before producing usable thrust. Static pressure can be overcome by using a higher thrust propellant or by using a smaller nozzle. Propellant- The propellant section explains which propellants are compatible with a given engine. Note that some engines can be upgraded to allow for additional propellants than is initially unlocked. Electric Power Need - This section explains if Electrical Power (measured in MegaJoules) is required for the engine to operate. Engines can require partial or full electric power, as well as mixed types that also use charged particles. Some engines like the RistoJet RCS, will switch to unpowered mode when insufficient power is available. These engines can therefore be used without KSPI reactors. Special- The special column covers any extra information about an engine that does not fit into a specific category on the chart. Thermal Thrust Bonus - This describes an engines ability to produce extra thrust depending on the propellant used. The temperature of the thermal engine also plays a factor on the thermal thrust bonus when factoring in thermal decomposition of a fuel. (More below in the Propellants section) WasteHeat effect- This explains how much Waste Heat is generated when firing a particular engine. Engines can both consume WasteHeat as well as produce WasteHeat depending on the engine technology used. Operating cost - This gives a general overview of the operating cost of running a engine. Electric engines are more expensive than thermal engines, since thermal engines have require less radiators. Vista Engines are very expensive to operate due to their high rate of consumption of Tritium.

Space in front of the vessel needs to be shrunken while space behind it the vessel is extracted. To shrink and expand space, you need to generate negative mass which can be achieved by exciting exotic matter. KSPI warp drive can generate exotic matter and use it to create a warp field. The amount of power required to create a stable warp fields depends on the speed and power of the warp coils. The speed of light itself requires the least amount energy. Traveling faster or slower requires more power. However speed is influenced by a large degree by the curvature of space, in other words, gravity. It means that the higher the gravity pull of any heavily body, the lower the maximum speed possible for a finite amount of power requirement. This effectively means that when a vessel is in a low Kerbin orbit, where the pull of gravity is significant, the maximum warp speed is very low. And since traveling slower than the speed of light requires more power, it means that it will be hard or impossible to generate enough power. To get around it, you need to bring your vessel further away from the gravity source or install more warp drive power. Warp Power is achieved by any of the 3 warpdrives in KSP, The Light Warp Engine, the Foldable Warp Engine and the Heavy Warp Engine. The amount of warp power is directly dependent on the mass of the warp drive. Warp drives also stack linear, which means it will not matter if you use 24 ton of light warp drives or a single large warp drive.
  2. ISRU Extended

    Hello everyone! Inspired by the XenonISRU mod, made by @Xyphos, I've decided to make a simple CFG file that adds the ability to make Xenon Gas, Solid Fuel and Ablator to all ISRU units in the game. The config file just steals the Monoprop making MODULE, and copies it a few times. In theory, it works with mods too (I've tested it with the Stockalike Mining Extension mod made by @SuicidalInsanity). Implementing other resources (Community Resource Pack) is a possibility for the future. License-wise, you are all free to do anything with it. Download here!
  3. I'm going to send a MAV on Mars almost empty (with just the right amount of Hydrolox fuel to land) and then refuel it trough RealISRU (sadly still not completed, but it works).I need help with methods to extract the fuel from the surface/atmosphere , chemical conversions and some math with it. Landing config: Mars takeoff config: I have 15 months to produce all that fuel.(around 85 tons)
  4. Is ISRU somewhat realistic?

    I feel like cheating when i use ISRU and was wondering... Are Drills and Conver-o-trons minimally based on actual realistic designs or prototypes?
  5. Hi all! The short question: I'd love to hear recommendations on orbital altitudes for a refinery operation that will mine ore on Ike and refine it in Dunan orbit. The longer explanation: For the last week or so I've been playing in Sandbox, working out how to most effectively set up logistical infrastructures all around the stock solar system. I started by setting up a full-coverage Comm relay and ScanSat (the mod) network around every body on the stock game. I've done all this before, of course, but never as methodically and efficiently as I'd like. So far the four inner planets are covered, and various satellite carriers are nearing their destinations at Dres, Jool, and Eeloo. Now I've turned my attention to setting up fuel depots and ISRU operations, and have two flotillas of fuel stations, mining landers, in-system tankers, interplantery tankers, etc. headed to Duna and Dres. All un-Kerballed and drone-controlled, but with enough modularity to be turned into crewed vessels in the future. (Before it's mentioned, I know depots and ISRU aren't necessarily the easiest or most efficient ways to explore the system, but for the purpose of this save game, that's what I'm playing with.) I already have a clear plan for Dres; with an ore miner tailored for landing on the planet and another dedicated to the asteroids surrounding it. They'll bring raw ore to an orbital refinery/tankage station. The reason for this post: I'm not sure exactly what I want to do at Duna. The mining lander is large (by my standards) and can bring 10,000 units of ore from Ike to anywhere in the Dunan system. The depot will refuel Kerballed missions to Duna, and a few re-usable Duna Lander/Ascent vehicles that will remain in-system for surface explorations. It may also be used to send re-fueling tankers further afield, particularly to Jool, though a full Kerballed expedition to that system is still only a drawing-board notion. SO... any suggestions, tips, or other observations? Specifically, will I be better served to keep the main Fuel Depot/Refinery station in orbit around Ike, or should it orbit Duna? If the latter, will a high (near the SOI margin), medium (outside Ike's orbit), or low (inside Ike's orbit) altitude work best for my purposes? Keep in mind the station itself has no propulsion, but is configured so the Mining Lander itself can propel the entire depot (and is in fact doing that right now, toward a Duna intercept in a few hundred days). There are also several fuel carriers around Duna (most of them leftovers from the Comm/Scan satellite missions) that can move fuel from the depot to vessels that need it. I'm asking not just in terms of absolute efficiency (as in launch costs and fuel consumption) but also in terms of my convenience and "playability" (i.e. avoiding days-long warping to rendezvous various vessels from high orbits), and finding a satisfying balance between the two. I hope I've laid out enough to explain what I'm looking for in terms of feedback, without droning (no pun intended) on too long. Note: I'm playing with a smattering of mods, but mainly for aesthetics. All my craft are (virtually) analogous to stock vessels, so a full mod list doesn't seem necessary. Beyond that I rely heavily on KER and KAC to design and keep track of all the (40? 50?) missions ongoing right now. Your thoughts appreciated.
  6. Hello, Kerbonauts, i was thinking to run a new career save as a sort of oil company. Now I just need to figure out how to mine as efficiently as possible. So my questions are: Which place in the Kerbol system is the best for mining? Should I convert to LF/O/Monopropellant? Use orbital refinery/storage stations? Thanks in advance.
  7. [WIP] This is a mod that adds extra Ore holding tanks for KSP, notably smaller ones. The stock Ore tanks in KSP, in my opinion, are too big for smaller landing craft (with the radial holding tank as an exception). Therefore, I am making a mod pack for myself that will give more Ore tank sizes, and also thought about releasing it to the public. Furthermore, the game has two inline-mounted ore tanks, both 1.25m and 2.5m, respectively. However, I do believe that they are too long to fit on a lander of some sort and I would like to make a half-version of the 1.25m ore tank, with exactly half the storage capacity. This wouldn't change the fact that it is 1.25m, though, it would only change the height of the tank. This would in turn enable it to be mounted on crafts more compactly. If this mod is what people may consider using after development, then please reply to this forum as this is going to go ahead for my personal use but I would like to see if the general community would like to also use these parts. The textures will probably be similar, but they might not be identical for reasons to do with copyright of Squad's textures. I will look into this. Speculated parts list: 0.625m Tiny Ore Tank; capacity around half of the 1.25 version. 1.25m Small Ore Tank; only difference to stock one is the height; therefore the capacity is half that of the stock 1.25m one. (Possibly) 3.75m Extra Large Ore Tank; for huge landers and bases; capacity twice the size of the 2.5m stock tank. These ore capacity numbers may change in development if they seem too high or too low for the relative size of the tank. All of above is true in the hope that my creativity skills with 3D design software is good enough to create a decent mod pack. Please submit your opinions below. Thanks. UPDATE: The first fuel tank is done. This one is the 1.25m half-variant one. The picture below shows the normal stock 1.25m Ore tank and next to it is the modded one. http://imgur.com/3mDW2tQ Cost: 750 Mass: 0.25 Ore Capacity: 150
  8. I am looking at a contract asking me to mine 1050 units of fresh ore from Gilly. I planned to send my mini-ISRU SSTO to Gilly to refuel for a later mission to Moho, but it's ore capacity is 150. Could I theoretically complete this contract? Bonus question: If so, will it still count the ore mined if I run the ISRU at the same time to immediately refine the fuel?
  9. I have a convert-o-tron 250 that is overheating even though the drills are turned off and TCSs are not at 100% cooling. https://www.dropbox.com/s/wtgc2z1f2mf2hgf/Screen Shot 2016-12-24 at 7.18.03 PM.png?dl=0 The ISRU works fine when only two converters are working, but starts overheating when the third is turned on. I have 6 x MKS Ranger TCS and 5 x large TCS at various places in the base. The base also has a PDU with the nuclear reactor running. Am I misinterpreting what "cooling" on the TCS means? Also, how do I interpret the thermal debug data shown in the action menu to make better sense of what I can do to stop it from overheating? Thanks
  10. Star Traveller (SSTA)

    Hey guys! Well I finally managed to make a working SSTA. I'm quite proud of this one. I usually just carelessly build spacecraft fast and forget things like solar panels, batteries ect. but this time I actually took my time in the SPH hanger and it turned out flawlessly! Well almost. (Forgot reaction wheels. ) This SSTA has VTOL engines, a functioning RCS system and enough DV to begin with to get to Duna or do a Minimus round trip without refueling. It also has four seats so you can easily put a pilot for control and an engineer to speed up mining. The VTOL engines are nicely balanced so landing on Duna with these will be a piece of cake! I still haven't tested its re-entry capabilities but I went up to about 1400 m/s before burning out on Rapiers so I assume it will be fine. The COM/COL placement might be bad so I am going to place an octagonal strut to mark the COL. This helped when I designed an aircraft launched shuttle because the shuttle carrier had stall problems. Download is coming soon. Still got tweaking to do so I thought I'd just put this here. Also Action group list + how to fly tutorial coming with download so stay tuned! Fire
  11. What does ISRU stand for?

    Might not be the right forum for this but I keep seeing the abbreviation "ISRU" around the forum. I tried googling it but it just brought up a bunch of forum posts using the term as if it's understood what it means. So my question is. What does it mean?
  12. [1.1.2] No Overheating

    Hello fellow Kerbalnauts! Have you ever started a drill or ISRU, only to be frustrated when it either takes forever to max it's efficiency, overheats, or needs a massive amount of NearFuture radiators or solar panels to dissapate the heat, which aren't always reliable? Wish the stock drills and ISRUs worked the same way Karbonite did before 1.0? Then you need... No Overheating Download on Spacedock [works with 1.1.2, probably 1.0+ too] This mod is just a simple couple of Module Manager patches, which completely remove the core heat system on Drills and ISRUs. Just start them up and let them do their thing. It also removes the core heat system on RTGs, I wasn't sure if they actually had any effect but I removed them just to be sure. It also works with Kerbal Planetary Base Systems, Modular Rocket Systems, and Near Future Electrical, but does not require them. It does however, REQUIRE Module Manager. You can get it here. That's all, and happy mining! This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.
  13. KRS Persistence N-S II - A Dream Completed At long last, the dream which has inspired over 440 hours of in-game time has been completed! When my eyes saw the wonder that was the ISRU units and the mining drills a couple hours into the game, I knew immediately that what I wanted to build was a rocketship that could travel to and land anywhere it wants, refuel, and return, carrying a bold Kerbal crew and all science experiments as well. In practical terms, this meant a rocket which could take off from Kerbin, travel to Minmus without refuelling beforehand, land on Minmus, refuel and then travel elsewhere with good delta-V to spare. The KRS Persistence N-S II is the pinnacle of all my spacecraft, and it represents the culmination of countless engineering mindset breakthroughs as well as a well honed piloting ability. Its maximum delta-V, travelling on the nuclear engines alone, is 6533m/s if my calculations are correct. Its takeoff flight plan is moderately complex. At launch, turn on the chemical engines only with the chemical rockets action group, then start performing a gravity turn at roughly 50m/s. I typically nudge it a small amount at 50m/s, then set autopilot at prograde after 2500m altitude. At approximately 5000m altitude, turn on the nuclear engines with the nuclear engines action group, and continue performing the gravity turn. Keep both nuclear and chemical engines on until the chemical rockets run out of fuel. Stay with the standard gravity turn until there is one minute left until apoapsis, then set it back to stability assist and hold until circularization of orbit happens. At this moment, you should have enough remaining fuel to travel to Minmus and land if you aim at Minmus accurately. This might take some practice. Action groups: 1. Toggle Radiators. 2. Toggle Cargo Bay Doors and Drill Deployment. 3. Turn on Drill. 4. Toggle Chemical Rockets 5. Toggle Nuclear Rockets. Lights: Turn on/off the two lights. Gears: Extend/Retract the landing gear. Naming: KRS Stands for Kerbal Rocket Ship, N-S stands for Nuclear-Science. I've made an S-S, Solar-Science version as well, but the Nuclear one has reliable electricity across the entire solar system. Download: KRS Persistence N-S II Download Link (KerbalX) Notes: This post was finally posted after weeks upon weeks of procrastinating on doing so, because I wanted to make this grand post showcasing all the SSTAs I have built, as well as my space stations and shuttles... but I realized that the problem was that I was taking too large a bite in one go, so I opted for this first. So... thoughts?
  14. I would like to start a discussion about Nitrogen on the Moon, and by extension on the Kerbalized version, the Mun The problem is Nitrogen is very rare or hard to acquire on the Moon. It is a relevant problem because Nitrogen is essential if you want to manufacture any Hypergolic Rocket fuel, oxidizer or monopropellant . There ain’t no easy accessible nitrogen deposits on the moon. Nitrogen is part of the Solar Wind deposited in the top soil but only in few part per million. Our only realistic hope of finding significant amount of Nitrogen is in encapsulated in Pyroxene and Olivine deposits that have not been liquefied near the surface (and lost their gas content). But these can only be found deep in the mantle which means they are hard to access. A 5 meter drill is certainly not going to find any significant amount of Nitrogen rock Ore. Therefore my conclusion is the stock IRSU system which requires nitrogen to manufacture LiquidFuel, Oxidiser and Monopropelant is highly unfeasible.
  15. Power for ISRU on Pol

    I put down a robotic miner onto Pol. I hit one of the high areas show by the orbital survey scanner. I put down my drills, and they pull in a bit less than .002 (whatever units). A bit less than on Minmus but OK. But I'm so far out, I figured I would use fuel cells, since they seem to work OK as supplements to solar closer in. But Drills + ISRU conversion is a net loss. It takes more fuel to power them than they produce. Am I just screwed? What do people use for power in such a situation? Just accept that you will need a bunch of heavy nuclear units?
  16. First off I can not say enough to thank all the great folks making some amazing mods for this game. The RO RSS community and its leaders/founders are just doing an amazing job and are really inspiring other people to new levels of exploration and mission planning. I recently came across stratochief66's thread "RSS - Challenges of Mars Missions" It involves using ISRU as a way to develop more feasible mission plans for Mars. I am trying to develop an orbital fuel/production station and a ferry for travel between the station and surface and for suborbital hops. These type of station and craft would be employed well down the road from the initial interactions with Mars like stratocheif66 is working on. I will start with one main station design and two ferry designs; one for crew transport and one for cargo/materials. Utilizing ISRU for production of additional fuel on the surface of the planet allows for much smaller craft with very reasonable round trip deltaV. Producing fuel in orbit also has its advantages that i will explore. Right now, I am working with a 70 tn prototype. It has about 4600 deltaV of fuel and can produce another 4600 deltV of fuel after landing over a period of 70 days. This is the crew variant and can support 3 persons for 210 days if needed. Crew, supplies, capsule come in about 7.5tn. So the cargo variant will have about the same capacity of 11% weight cargo for a 70 tn craft. This is a completely reusable craft, and will use a pure propulsion profile for ascent and decent. I may incorporate aero interactive devices of some sort to shave some deltaV requirements, but for now I am trying to keep it simple. I also do not want to use anything that I do not feel certain is modeled as closely as possible to a real life object. The orbital fuel station prototype is fairly simple and, when full, can refuel/restock a ferry twice, and has tank space to take on resources for fuel production in orbit. It will develop more as the ferry design is refined and we get a better understanding of the frequency of the initial transit scheduled. Even as it stands now it could be mirrored on a central hub or expanded to any radial degree desired. All resources are in color/pattern coded tanks so that I can get used to the proportions of volume and weight of the various resource components as I develop designs and test things. I am working with the basic RO RSS install and I only use RO modified stock and procedural parts. ISRU and Heat Pumps are my two part pack additions for my current testing. I use all sorts of visual stuff and control/metrics mods. Ill paste screen below with full mod folder. I have two videos of some of my initial flight tests. Ones is a decent from the orbital fuel station to the surface and the other is the ascent from the same location on the surface to the orbital fuel station after refueling with ISRU. Both trips had 500+ deltaV to spare so we are close to the set up that I will use. I would like to have 10% fuel reserve in the final design if possible.

I will also in the future include flight profile information to better help you get similar results. I have an educational background in math and physics, but I am a total newb to this game, community and rocket science in general. However, it is all about solving small problems and I love to do that. I am open to suggestions and alternative methods for what I am doing My next goal is to land two craft in close proximity. I will be installing scansat and researching to choose a good place on the equator for my landing site. Let me know if you are aware of a good spot. Right now I would like to be able to land +or- 0.5 km from a given target. Past close proximity landing, I have two areas I would like to address as I develop my station and ferry. One is to move away depending on the RTGs I am using for power. My current ferry prototype is using two of the largest chemical engines and will most likely be scaled back to one or two of the smaller units. This will increase the time on the surface and I will need to look at what my limits will be regarding that. In moving away from the RTGs, I need to develop a solar plan. At current, I am thinking solar panel systems that will be deployed/assembled by hand/robot once landed on the surface. While I could build a permanent large solar installation on the surface and use that to power the ferry's refueling process, I prefer to contain the solar harvesting potential in the ferry itself. Most all initial craft, I think, will need to be lifeboats, and all but stand alone systems. Relying only on permanent solar installations would also limit sub orbital hop range. Later these solar installations will be present, but for the initial ferries and surface infrastructure I want as much self sufficiency as possible. Two is to take another look at boil off and scaling for time and active craft in game. We have good hardware/mods to keep fuels at the right temp, but I would like to look at performance of cryo systems in martian atmosphere and power requirements. I know this will take a decent amount of power, and there may be limitations in direct exposure environments. Heat-sinking and other methods of local thermal stabilization may be needed, and long term, desired for efficiency. The station producing fuel in orbit will require the CO2 ferry and I have to really look at the fuel cost of bringing CO2 up. The savings in not bringing LqdHydrogen to the surface are small, but I think large solar solutions for processing will be easier in orbit. SO right now I'm going to scale down fuel production on the ferry and see if I can get a deployed solar solution to power it on the surface. Then based on a flight schedule of two ferries, on their new fuel period, I will see how much CO2 I can run to the station. Then I will make a fuel production schedule for the station. Then I can make a LqdHydrogen delivery schedule from earth. Then I can look at the whole chain and see the rough potential of two craft and one station, with LqdHydrogen support from earth. Then I can do a similar chain set up where all fuel is produced on the surface in a permanent surface installation. Fuel will be lifted via ferry to the station and LqdHydrogen brought to the surface via the same ferry. The station will still receive Hydrogen support from earth. In the end, I imagine, it will be a combination of the above that will take place for matters of convenience and complexity reduction as well as efficiency. While some of this can be explored by my rudimentary math, I find working models to really spell it out much better.
  17. I have an ISRU design I've used a bunch of time. I put one down on Pol. I was having trouble getting enough ore to keep everything running and come out ahead, but other than that, it was working fine. I jump away (letting it run) and come back. I haven't gotten anything so I left click on the drill and it says "no ground contact". It was working before I left. I is clearly in the ground? Anyone know what's up? Here is a picture

  19. The Mun Polar Crater ISRU Challenge Stock Sandbox This is about sending a complete autonomous ISRU package to scan resources, mine ore, convert and deliver the fuel back to a station in an equatorial 250 km circular orbit around Mun. Using the GameSeed = 1823959382 in the persistence file* will set the resource map and Mun's polar crater will have the highest concentration at 80% resources. This area was challenging because the sunlight had long periods of both dark and light plus returning to an equatorial orbit. Send a complete package to an equatorial Mun orbit. Disembark Scanners once inside Mun SOI and send them to a polar orbit. Scan Mun for resources. Disembark the ISRU to land in the crater. Mine for resources and convert to LOX. Deliver to an orbiting fuel depot. Score is based on total vessel cost over the total fuel delivered to orbit. Gather as much as you can in the 90 day time limit.

Edit the save or persistence file and look for ResoureScenario and then Resource_Settings This works in the 1.1 prerelease not sure about earlier versions. I used to reload and rescan to achieve the right game seed. This example of initial orbit setup just before landing the ISRU. This is my A ISRU AIO vessel. Delivered Low and High Orbital Scanners; Lander / Heavy Fuel Truck; Rover Light Surveyor, Rover ISRU; Orbital Fuel Depot; Light Fuel Truck This vessel is intended for interplanetary ISRU and testing this on Mun in the Polar Crater seemed to be the best litmus test. The mining operation will begin tonight and I will post my results. Postponed the operation and redesigned the vessel for the challenge. Going with this cost reduced version. Managed to shave 70k off the original. Edit: The original ISRU version had no issues with heat and in prerealese 1.1 it is now a problem. Tried adding fold able type radiators but they sit idle. Sure glad to see that bug is squashed #8157 New Build: I decided to rebuild and now working on a Mega Miner. It scales in at 45 tonnes and has 14 heavy drills. Needs more cooling.
  20. This is a very simple mod that allows for ISRUs to convert fuel without the need for external fuel tanks. I understand that there are snippets of MM code floating around out there that performs this very task, and I'm sure some of those are much more streamlined than mine, but I am releasing this mod anyway, since there are players out there with little to no experience using Module Manager. Downloading and installing a mod can be trying enough for some users, but it's still easier than writing a patch. What does it do? As stated above, it makes it so that the Resource Converters are able to convert fuel from ore being mined even if there are no ore tanks present on the craft. It does this by adding a very small storage capacity to all parts with a resource converter module using ore as an input. Converters will only be able to store a maximum of one unit of ore, so once you leave the surface you'll no longer be able to keep converting fuel. This is to avoid exploits. Why would I need that? It's perfect for science hoppers for example. Those types of crafts are not buildt to provide a stockpile, and the mining is not the main focus of them. They only have converters and harvesters to be able to refuel, and as such the demand to include external ore tanks becomes a pain in the behind. Does it work with 1.1? Yes and no. The patch code is tested on 1.1 and it works just fine. However, I have not included certain components needed to make the mod run in 1.1 and this is a personal choice for the time being. Making the mod compatible with 1.1 is only one simple step away though, and the way I see it, if you can't figure out what that step is, you should most likely not be testing a beta build with mods. This is not me judging you, it's just my way of saving the developers a bit of headache. As soon as 1.1 is properly released I will update the mod accordingly. Did you make this all on your own? Are you a master coder? Not really and not at all. I know some basic python and that is about it. This is a very simple mod, and I still had to recieve some help to make the code more stable.

  22. ISRU Rhino SSTO Explorer Mk1 Jool 5 Mission Hi All Here is the Mission Report of a new try for the ISRU Level of The Ultimate Jool 5 Challenge - continuation for KSP 1.0! , my first try since the 1.05 update ! I started a new career in hard mode, so the challenge is a little harder in ISRU version, because of the restricted Ore availability... To be efficient, i wanted to do a SSTO ship with 4 Kerbals ( The Orange Suits boys and girl ), the minimum of fuel, two big drills and a big converter to avoid long mining time. BTW, that's the first mission to Jool in this carreer, so i also needed the full science pack... FOR SCIENCE !, and to find good Ore spots. After a looong brainstorming and simulation testing (Thank's HyperEdit ), i ended with this ship: The ISRU Rhino SSTO Explorer Mk1 ! ( <--- Craft file here) 235t., 82parts, 225097funds, 1 Rhino, 2 Vectors (to help Kerbin ascent, and if a boost is needed), 16155LF and 19475Ox. The Vac. Dv of this ship fully fuelled is 4719m/s with the three engines On, and 4836m/s with the Rhino only. The only mod used in this mission: KER. One launch, no sats, no rovers, just 4 Kerbals and a ship Total cost of the mission: 225097 - 201775 = 23322 funds ! Now, it's time to go... First chapter of the mission: To Jool ! In this chapter, the Kerbin ascent, Minmus Journey, ISRU refueling, and first burn to Jool System Second chapter of the mission: Vall and Laythe ! In this chapter, the Jool System insertion, the Scanning of Ore and the Landing on Vall and Laythe Third chapter of the mission: Bop and Tylo ! In this chapter, from Laythe to Bop, and... Tylo Fourth and last chapter of the mission: Pol and Kerbin ! In this chapter: from Tylo to Pol, and back to Kerbin ! Fly safe with Valentina !
  23. This is an ISRU factory I'm planning on sending to Minmus. It has: 1x Drill-o-matic (the 1.25 ton version, not the Jr.) 1x Convert-o-Tron 125 (the smaller one, because it balances nicely weight-wise with the drill) 8x radial ore tanks (at 75 ore per tank, total capacity 600 ore) 2x Thermal Control System (medium) 4x Radiator Panel (large) about 4.5k electric charge capacity 8x gigantor solar panels. I'm using some mods, but most of them hopefully aren't relevant to this question -- exception might be TAC life support because the kerbals need electric charge to stay alive. The complete list is: Chatterer - 0.9.7.86 Contract Configurator - 1.9.6 Contract Pack: The K Files - 1.1.1 Contract Pack: RemoteTech - 2.0.1 Contract Pack: Tourism Plus - 1.4 Kerbal Attachment System - 0.5.5 Kerbal Engineer Redux - 1.0.19.4 Kerbal Inventory System - 1.2.5 KSP-AVC Plugin - 1.1.5 Final Frontier - 0.9.8.1882 RCS Build Aid - 0.7.7 RemoteTech - 1.6.9 SmartParts - 1.6.6 TAC Life Support - 0.11.2.1 Kerbal Alarm Clock - 3.5 TweakScale - 2.2.6 Waypoint Manager - 2.4.5 So here are the actual questions: If I'm planning on running the drill and the convert-o-tron pretty much continuously until the LFO tanks are full... Which processes ore faster, the drill producing the ore, or the convert-o-tron 125 turning it into fuel? In other words will my ore tanks fill up because the drill is faster, or empty out because the convert-o-tron is faster? If my ore tanks fill up, will the drill shut down? If so will it start back up when some space becomes available? If my ore tanks empty, will the convert-o-tron stop working, or simply wait for more ore to be put in the tanks? I know the answer to question 1 potentially depends on the abundance of ore at the dig site, but I'm looking for a general answer based on people's typical experiences. This is my first attempt at using the stock ISRU system, I don't want to waste funds and time sending a mission that has no chance of working, and for mental health reasons I don't want to start up a separate sandbox to test this out for free first. Thanks in advance for any replies. Hints regarding electric charge and heat dissipation would also be very welcome.
  24. I get my fuel from Minmus using a large ISRU lander. (photo below). I seems to take a lot longer than it did on some previous missions. In my latest fuel mission, I have 8 drills taking up 0.00525 units of ore/second. But after 30 days, I only get 1103 units of liquid fuel. (Using Lf only on the ISRU converter.) By my math, this is 1/5 of what I should have gotten?
  25. Hello, this is my first entry here. I wanted to share my Jool 5 mission with you. Thought about this for a few months now, but never had enough time to do it. But, the mission: It´s an IRSU level entry, and because thats not enough, i´ve put a station on my ship, that i´ll leave at Jool when i return. The ISRU unit is built into that station. Mods used are: KER, MJ (call me lazy, if you want ), Kerbal Alarm Clock, NavHud, AntennaRange, EVE, scatterer, Planetshine Part 1: Planning Part 2: Orbital construction Part 3: Journey to Jool and first mining run Part 4: Mining on Pol Part 5: Laythe Part 6: Tylo and Vall Part 7: Bop and back to Kerbin
