R E A L I S M O V E R H A U L [1.7.3-1.8.1] Realism Overhaul v12.8.1 [17 April 2020] License: CC-BY-SA Intention: Realism Overhaul is a mod that makes Kerbal Space Program behave more like real life. If you're interested in seeing what it's like to fly rockets in the real world, this is the mod for you! Realism Overhaul does this by combining and configuring other mods, and mod and stock parts to perform as their real-life equivalents. You can expect things to be a little harder, and rockets to be a bit bigger, but the scenes far more epic, and the accomplishment that much greater. Some of the most signfiicant changes include: Engines have real sizes and performance values, and use real fuels. Most of them have limited ignitions and suffer from ullage. Pods are as large as their real-life counterparts and weigh what they should. Propellant tanks have correct dry mass ratios. Solar panels don't produce massive amounts of energy, but they are lighter. Similarly reaction wheels aren't magically powerful anymore (though they still don't require momentum dumping). _________________________________________________________________________________________________________________________________________________ TOOL SPOTLIGHT Generic Engines - Web Version by PatPL This tool allows you to quickly configure engine configs in the web browser on the fly, choose from over 120 engine models and even assign TestFlight configurations to it.

Hi there, and welcome to the Real Enhancements development thread. This mod aims to continue and expand pozine and imkSushi's Real Solar System Expanded mod. I plan to incorperate and restore the majority of objects in the mod My aim is to create a modular experience, so people can download packages based on their interests and their ability. I know this seems ambitious (especially RealStars, that one is going to take a while) RESPOSITORY LINK (outdated): https://drive.google.com/drive/folders/1oCeqlZ4fBs6TNvnN0R57TMqhKbSBVzzO?usp=sharing Github: https://github.com/AR3S-Vega/RealExpansion/releases It is recommended to install RealPatch to fix inclinations, other wise the inclinations of newer objects will be broken Discord Server (because Kopernicus won't give me a channel): https://discord.gg/pWfYbfm Requires: Kopernicus ModuleManager ModularFlightIntegrator RealSolarSystem Skybox requires TextureReplacer Catalog: As i said i wanted the mod to be modular, and you will be able to download each package individually. So if you are less experienced with RSS/RO you can download the NEO package, and if you want a challenge you could download Stars or ExtremeTransNeptunian objects Things i want to add (yeah i stole this image from imkSushi's thread) Current Status: Abandoned Credits: Me ("Our Benefactors") for doing something @Xurkitree for help with Kopernicus and RealAftermath @Noah the Smol and @GurrenLagannCWP (if I have the right accounts :P, most of the discussions have been done on discord) for working on RealHypotheticals pozine for making RSS Expanded in the first place imkSushi for restoring RSS Expanded NathanKell for Real Solar System AndrewDraws for RealExoplanets Gregrox for letting me use his sunflare TSMP for Kopernicus Squad for KSP imkSushi's old thread: pozine's old thread: This mod is licensed by the Creative Commons Attribution 4.0 International - http://creativecommons.org/licenses/by/4.0/

Announcing the 0.1.0 alpha release of Simple Procedural Engines. Aerobees too small for you? F-1 slightly too big? Agena more thrust than you need? Then have we got solutions for you! S. P. Engine allows you to create procedural engines from several real-world-inspired families, by setting the thrust and ignition count within the supported range. After tooling a design, you can follow its upgrade path as you unlock further techs, saving many many funds as compared to a brand new design. S. P. Engine is built for use with the Realism Overhaul suite of mods, and in particular has a hard requirement for RealFuels. (That's why I'm releasing for 1.3.1 rather than something more recent; the various Realism mods are still back there.) Currently supported engine families (with mnemonics): A: (Aggregat) Ethanol/LOx booster. B: (Bees) Small aniline/furfuryl/nitric acid sustainer. D: (Delta) Pressure-fed hydrazine/nitric acid upper stage. F: (F-1) Huge kerosene/LOx booster. G: (aGena) Pump-fed hydrazine/nitric acid upper stage. J: (J-2) Large hydrolox upper stage (and later aerospike sustainer). K: Kerosene/LOx booster up to about 1MN thrust. (Like LR79, H-1 and Merlin1.) L: (Lr105) Kerosene/LOx sustainer. Matches nicely with K-class to make Atlas-style stage-and-a-half. M: (M-1) Massive hydrolox upper stage (later also sea-level). Q: Small, throttleable hydrolox upper stage engine. (Like throttling RL10s developed for Lunex.) R: (Rl10) Small hydrolox upper stage engine. S: Small staged-combustion kerosene/LOx upper stage. (Like S1.5400/11D33/RD-58 family.) Several more are planned. Read this far? Download S.P.Engine 0.1.0 and give it a try!

I proudly present to you my latest project. A manned grand tour of the Uranus system. The time has come... The year is 1992, the main goal of the Othrys program - landing humans on the moons of Saturn - has just been accomplished. A new, even more ambitious goal has just been set for NASA. Landing astronauts on each of the 5 moons of Uranus: Miranda, Ariel, Umbriel, Titania, and Oberon. Coelus Program just began... Modlist in the description.

Hey guys, I changed now to RSS/RO and I like the realistic mechanic BUT I have some problems. First of all the rocketbuilding center. When I want to seset something with "ctrl" and "z" parts remove change their place and also hover in air.... and often the nodepoints disappear. Second I have installed RSSVE but the clouds and citylights are not there. The texture is red see picture: And third when I load a save data while I am in flight veeeeerrry strange things happen im not able to control anymore and the camera view is not avaible anymore. See also Picture the ship is there but in stage settings left many parts are gone..... I use for this Mod KPS version 1.8.1 I hope someone can help me or can somebody give me a good working package to download via drop box or sth else mabye also in a higher KSP version ? Best regards Muddyblack

i have recently started playing RO/RSS and wondering if they are any other mods that are not officially supported by RO/RSS but work or have configs.

After a couple days of research and understanding the Real Solar System files, I've finally figured out how to change the date in RSS DateTimeFormatter. It's not too complicated and just takes a few minutes. The first thing you need to do is go into your Kerbal Space Program file (with your GameData and whatnot) and type into your file explorer's search bar, "persistent.sfs". Depending on how many saved games you already have, there will be the same number of these "persistent" files. Choose any because what this will do is going to affect all your saved games (if you don't want your other games to have a different date, take them out of the KSP saves folder). Once the .sfs file is opened, you need to scroll down until you see "UT" which itself is under "FLIGHTSTATE". Next to UT is a set of numbers. For those that don't understand what these numbers mean, they represent the number of seconds since the start of the game. This is what you need to change to have the save game set to a different date. Now you must figure out the number to replace the current one. Go to this website and, depending if your desired is before or after, put 1/1/1951 (the default date in Real Solar System) in Start Date or End Date. Then put the desired date in the opposite date section. For an example, I will use the beginning of 1942 as the replacement date. Click Calculate Duration and look for the large bolded text saying the number of days in between (3,287 days as per the example year). Now it's time for some quick maths. Multiply the number of days by 4 (as Kerbin days are 1/4 of an Earth day) then multiply that number by 6 and multiply again by 3,600 (found that out here). You now have your replacement number. Go back to your persistent.sfs file and delete the number already in UT and type in the new calculated number (of course not with commas). If your wanted date comes before 1/1/1951, then put a dash in front of it to make it a negative number. When done, save the file and close out of it. There you go. But before you go back in the game, there's one more thing you will need to do. What this is going to do will just make the planets and moons correctly aligned accurately according to the new date. Go into the Real Solar System file that you have in GameData and look for "RSSKopernicusSettings.cfg". Within it, scroll down (but not really because it's close to the top) until you see "Epoch". It will also have a set of numbers next to it. Epoch, in astronomical terms, is a fixed date that is relative to planetary/stellar measurements. The number you will see (-31542641.784) is the epoch for midnight, January 1, 1951. You need to replace this epoch with another that is accurate to your new in-game date. Use this website to find the epoch by typing in the date that you had replace the default earlier (just type in 12:00 A.M. for the time and keep it at GMT (Greenwich Mean Time) as that it the time zone RSS uses) and clicking Human Date to Timestamp. Your epoch replacement (-883612800 for the 1942 example) will be next to Epoch Timestamp. Copy the number (if it has a dash to make it a negative number, keep this) and go back to RSSKopernicusSettings.cfg. Select the epoch number and then paste (Ctrl and V at the same time) to replace it while also deleting it at the same time. Save the .cfg file and close out of it. You've now fully completed the new in-game RSS DateTimeFormatter date. Go to your KSP save game that has the changed date and you can see now that the date is, in fact, changed. Head into the Tracking Station and look to see the different planet alignments. Unless you have a clever eye, and you probably won't be able to tell anyway, but the planets really have moved since you changed the epoch.

I love Principia but find it too time consuming to constantly switch around to do 'orbit maintenance' when there is long term precise requirements. Real satellites have a delta-v budget, ion/rcs engine and a team of people dedicated to this. Anyone know of any mods that will maintain my n-body orbits for me (obviously only until my fuel is used up)?

I've been trying to install the rp-1 modpack for 1.8.1 and i followed the guide closely "https://github.com/KSP-RO/RP-0/wiki/RO-&-RP-1-Installation-for-1.8.1" but after starting a new save i noticed that all procedural tanks have pitch black textures, i tried to install manually and change versions of the textures unlimited mod that is listed as a possible cause for this problem but nothing changed, so i decided to come here and ask for help :) . if u guys need anything from me to help solve the problem i will be happy to assist.

3 months in the making, I present to you my masterpiece. Hope you enjoy and thanks for stopping by! (YT really doesn't like dark scenes btw)

Hi everyone, First of all i'm new to this forum (even though i'm following it for a long time now) and i want to thank you all for the wonderful job you're doing with it. I'm experiencing a bug with my install, All the science equipment stopped working, more precisely i can't right click them, only the film return camera displays the option of opening the doors but i can' run the experiment, after some testing i found out that only the magnetometer boom and the plasma detector are working proprerly. This bug occured during a Carrer save file, all of a sudden it stopped working (i noticed it after a moon landing) and only the vessel built and launched before that mission have working science equipment. The last mod i installed was FASA, i tried to disinstall it and start a new carrer but the bug is still there. Here is the list of mods i have installed: Soviet Probes v2.0 Soviet Rockets 1:v2.1 Stock Extension v.25.2 TACLS v0.12.3.2 TACLS RO config v11.3.2 Taerobee Stockalike x-1_more 1.2.3 Tantares 36.0 Tantares LV TextureReplacer v2.4.13 Toolbar 1.7.12 Universal Storage 1.1.0.15 US Probes Pack v0.53 Ven’s Stock Part Revamp v1.9.5 Soviet Engine Pack 0.1 Soviet Engine plugin v2.3 SmokeScreen Extended FX Plugin 2.6.17.0 Skylab v1.5 ShipManifest 5.1.2.2 ScanSat v16.6 Rocketdyne F-1 1.2 RemoteTech v1.7.1 Realistic Progression 0 v0.51 RO Craft files v11.3.2 RO v11.3.2 Real Heat v4.3 RealChute v1.4.1.1 RSS Texture 4096x2048 v.10.4 RSS v.11.4.0 Real Scale boosters 0.14.5 Real Plume 2:v10.5.1 Real Fuels rf-v11.3.1 RCS Build Aid v0.8.1 Procedural Parts v1.2.5 Procedural Fairings - For Everything v0.2.0 Procedural Fairings v.3.17 Persistent Rotation 1.8 Near Future spacecraft 0.5.1 Solar Core 0.6.2 Solar 0.6.2 Propulsion 0.7.4 IVA Props 0.5.1 Construction 0.6.4 Module Manager 2.6.25 Modular Flight Integrator 1.1.6.0 MechJeb2 2.5.8.0 KSP AVC 1.1.6.1 KSC Switcher 0.6 Copernicus Planetary System Modifier 2:release 1.1.3-1 Kerbal Renamer 0.6 Kerbal Joint Reinforcement v3.2 KAS 0.5.9.0 Hangar Extender 1:v3.4.8 Forgotten Real Engines 0.7.1.0 Firespitter Resources coffin v7.3.0 Firespitter core v7.3.0 Filter Extensions - Plugin 2.6.0.1 FAR 3:0.15.7.2 Dmagic Orbital Science 1.3.2 Deadly Reentry Continued v7.4.7.1 Custom Barn Kit 1.1.9.0 Contract Configurator 1.19.0 Connected Living Space 1.2.3.0 Community Tech Tree 1:2.4 Community Resource Pack 0.6.3.0 BahamutoD Animation Modules 1:v0.6.3.1 B9 Part Switch v1.4.3 B9 Aerospace Procedural Wings - Fork 1:0.40.7 Atomic Age 3.2 Antares.Cygnus 1:v1.1 Advanced Jet Engine v.2.7.2 FASA 5.44 All of this mods except FASA were installed using CKAN.

Someone would have or could make a configuration of Tantares for RSS / RO 1.6.1, I would like to be playing with the N1 but the mod that I usually used for some reason is pulling a lot of ram, anyway this is another problem, but then I remembered from Tantares and I thought it worked on RSS I tested it and found out that I need to change the mod settings to work, could someone do that?

Here's a video i made of my manned mission to mars and its two moons i did recently it took 3 days to do.

The pttachment point is on the sde is this normal I only just started with ro with rp-1 and have been having alot of fun with but this is stopping me from making anything. Thankyou in advance.

Early crewed Moon landing Nasa proposal Gemini Lander I've just managed to do this early "low-cost" Nasa proposal to a cheap and fast moon landing, since our space program is often running out of money ( big hug to RP-1 team) . Of course, this little thing never flown in reality, was one of the possible applications of the Gemini spacecraft (one design even was planned to a Mars landing!). First, have to launch the landing module, attached to a Centaur stage (2 RL-10 with restart capacity), in LEO. Launch vehicle is the great Titan III-E: first stage 2 solid boosters and LR-87 (burning aerozine/NTO in AJ-9 configuration), second stage is LR-91 (same, AJ-9 too), and last stage is hypergolic Centaur stage , just to finish orbit. Of course we have to launch in the plane of the moon, so waiting, to have right relative inclination. Initial ascent Booters separation, aiming orbit at 250 km: Then LR-91 firing, and finally centaur stage just a bit to finish the work: The Lander is hidden in the fairings, and on top of that, agena probe core/docking port for gemini spacecraft. Now let's launch the crew! The gemini spacecraft have been upgrated with a better service module, providing enough deltav to hopefully come back from moon orbit, and enough life support stuff. Same Launch Vehicle. Crew: Neil Amstrong, Alan Shepard. And launching from Cap Canaveral (same as before) Standing by the launch: Neil and Alan photographs from the launch tower for their respective wives when they will (we hope) come back: Now get in, and launch! Waiting to have the same inclination as our target and an acceptable phase angle to minimize rendez-vous deltav cost. Hmm, all this thrust, glorious. After getting rid of boosters and first stage, centaur is as before finshing orbit: After rendez-vous maneuver, let's dock this! Docked! Now go for the moon: After about 2 days of travel in this tiny spacecraft, and after circularization burn, Neil Amstrong is getting in the Landing Module, leaving Alan Shepard a few hours alone in moon orbit: Undocking, and centaur stage firing its last precious amounts of deltav doing the decceleration burn, after that the lander will be released juuuust to the do final descent, at about 2000 m above the terrain, meaning Neil Amstrong will land with a Centaur stage going to crash.. just under him. What a brutal Nasa idea! Almost, almost, now let's do it smooth (the lander is propelled with 1 or 2 kn engines burning Aerozine/NTO (unthrottable) and have very few life support on it). I made the lander with descent and ascent stage, but not necessary at all, as you can see. And done! Now let's get out quickly of this flying scrap, plant a flag, take one or two pebbles for our scientists, eat a snack on moonar surface, and get back! Good bye moon: Rendez-vous with Gemini, and EVA crew transfer: Now let's go back to our dear old Earth, have to aim the return Pe at 71 km to capture first, and then land, for good ( since the Gemini heatshield will burn up under that, and we don't wan't that). Second and final reentry: Chuutes, chuutes: And gloriously, marvelously, splashed in the Indian Ocean:

Hi @pap1723, hi forum I started a new RSS + RO + RP1 career on KSP 1.6.1 recently and followed the installation description for RO / RP1. They suggested, amongst other mods, RO Tanks. The RO Tank I should have max 560~ liters. When I downsize the diameter to 400mm, the maximum length of the tank i can setup is 600mm which is about 46 liters. Is it as intented to have that ratio? Thanks and kind regards PatSch

I've been trying all day long to install and play RP-1 but the planets never change to the RSS one's. even if I change the game version(1.2.2, 1.3.1, 1.6.1), install manually or via CKAN the same problem happens and i just don't what to do now

Hello, I am playing KSP 1.6.1 with RO and a bunch of other mods, however I am struggling to replicate the Luna missions. I am using the pre-made "RN Stock Luna 2" craft (from the Soviet Probes and Soviet Rockets mods by Raidernick), the craft has plenty of Dv, but I am still unable to reach/impact the moon. Correct me if I am wrong, but here is my understanding of how the real mission went: 1. Launched from Baikonur 2. Reached an altitude of about 200-300km (could not find an accurate number), before the main engine of the second stage ran out of fuel 3. Removed the fairing 4. Decoupled the upper stage, and lit it's vernier engines 5. At the right time it lit the upper stage's main engine as well (the RD-0105) 6. When the impact orbit was reached (or in the case of Luna 1, slightly after) the engines shut down. 7. Decoupled the probe 8. Impacted/flew close by the Moon Here is what I am doing in KSP RO using the RN Stock Luna 2 craft: 1. Set the Moon as target 2. Wait until the inclination of the orbit is as close as possible to the one of the Moon (around 17.5 degrees, according to Mechjeb's Rendezvous Planner) and the moon is in a proper position (not too far behind or in front of what would become my transfer orbit trajectory) 3. Launch 4. Reach about 200-300 km, decouple, light verniers, etc. 5. Use Mechjeb's Maneuver Planner to create a node automatically 5.1. Select "bi-impulsive (Hohmann) transfer to target" 5.2. Select "intercept only, no capture burn (impact/flyby)" 5.3. Select "create node at next apoapsis", because otherwise it creates a node after one orbit has passed, and the craft is not in orbit 5.4. Click "create node" 6. Align the upper stage with the node, wait untill the required burn time is split 50/50 before and after the node. 7. light the main engine, burn until fuel runs out. The craft itself (according to Mechjeb's Dv stats has 13176 m/s of Dv. However no matter what I do I still fall short by at least 1000 m/s of Dv on the upper stage. I tried warping back and forward before launching to change the position of the Moon in it's orbit, tried playing with the inclination and initial altitude, but no luck. What am I doing wrong, why am I unable to reach the Moon? I tried looking for a tutorial/info about this mission and it's mission profile, but I was unable to find anything detailed.

Who knows how to add engine emissive in RO. Structure "name = FXModuleAnimateThrottle" seems doesn't working with real plumes. ksp 1.3.1 mods: realism overhaul, real plume, real fuels,solver engine, real heat, real chute, rss

This was done with the WIP Raptor engines, but I downrated them 20% from what's in the current RO based on new chamber pressure estimates from SpaceX. Had a lot of fun (no really!) playing with KOS to set up a precision booster landing program. Thanks to CalebJ2 for sample code and for getting Trajectories support added to KOS. First Stage VTVL, Second Stage VTHL, 100 Tonnes to orbit. I have the unedited version if anyone wants it, but it's over an hour due to the long shallow re-entry.

RealSolarSystem Easter Eggs hunting! In my rp-1 career, as I was doing some unmanned Moonar landing mission, I saw, once orbiting the moon, that an anomaly was in my orbit trajectory, so I decided to precise land there, and I found this: A Neil Amstrong memorial!!! It excited me to found all others ones present in Real Solar System. So just started a new sandbox game to give it a try, and challenge my self. First I'll deal with Earth of course. Here's what the map says: I will start with the one which is North-East of Cape Canaveral Let's HUNT!

Real Solar Sytem / Realism Overhaul / Realistic Progression 1 Kurgutovich Space Program, the Soviet way! Career mission reports Summary Early launches One of the first missions, a jealous copy of the V2 rocket, the K2. After WW2, well juust after the capitulation, a race occured between URSS and USA to found the V2 factory and learn about it, also, found its creator, Werner von Braun, but Americans were first! It was maybe the very beginning of the space race before actually doing it in space So the engine here is a early RD-100 (copy of the V2 engine) burning Lox/Alcohol: The goal is simply to learn about rocket guidance and rocketry in general (engines), by the way we also added some temperature and pressure sensors to studie the upper atmosphere, and the space border. Launch site: Baikonour cosmodrome max Altitude: 160 km (suborbital) Then, with this good knwoledge, we upgraded the engine to RD-101 for increased performances. This rocket was also fully recovered, to studie the reaction of a spacecraft after exposure to space environement. By the way, this was the first ever recovered object after reaching space. Morning launch: After reaching the space limit, deploying Kevlar drogue chute to start safely slowing down the rocket, until the main chutes deploy few hundred meters before the surface: And landed! From what we see, the rocket seems to have been exposed to very high radiation level, that confirms our scientists predictions (to celebrate that, they will simply take a vodka bath in the R&D center) Then, still upgrading the initial RD-100 engine, the K2-c rocket now allow a heavyier payload. So a mission was launched, to bring back the first earth photographs from space! Farings jetisoned, taking photos.. Released the return camera, it landed safely in the Kazak' desert. And finally, last upgrade of the K2 rocket, that broked an altitude record of 550 km!! Now, the polit bureau wan't to impress the world with its puissance, so they idea is to send some Kerbals up there.. This will be the Bayan program!

Hi. I have Kerbal Space Program 1.5.1 with Making History Expansion. I also have Realism Overhaul and its dependecies: Real(Chute, Plume, Fuels, heat), ModuleManager, Advanced Jet Engine, SmokeScreen, Kerbal Joint Reinforcement, and Ferram Aerospace Research. Although, the game says Realism Overhaul, Real(Plume,Fuels,Heat, and Chute), Kerbal Joint Reinforcement and Ferram Aerospace Research are only compatible with 1.3.1. All these mods takes away some needed components, and replaces them with different ones. But, not any from Realism Overhaul that I know of.Sure, there's an "SLS Tank", but it's just a few 3.75m Kerbodyne engines placed on to of each other. It even says that in the description! Do I have to downgrade to 1.3.1? I don't want to lose the features of the Making History expansion.

Helle there, does anyone know if there is a way to calculate the amount of fuel which boils off in a specific amount of time? Thanks in advance.

Hello there, I was just building a new spaceship when I realised that every RCS thruster I put onto my ship adds at least 100kg of mass to the total mass. Even the smallest ones. In the description of the thrusters it says they weight between 3 and 14 kg. Its pretty annoying because as you might imagine it makes a huge difference especially with the upper stages when it suddenly weights 400kg more. Any help is appreciated. Thanks in advance.
