So, its time to land an unmanned probe on the surface of Venus. I've never done this before. Do you have experience or any advices for me? Do I need additional engines or is a single parachute enough for a safe touchdown ? I had the Idea to place everything inside a 2m ServiceBay with a Heatshield Down below and a parachute on the top, do you think that could work? By the way, here is my current TechTree:

Hi guys! hope everyone's doing great! I was wondering if someone ever managed to build a Skylon or similar SSTO spaceplane with the B9 motors and configs provided in RO. I only managed to get to 4.5km/s, almost half way to orbit - I can't seem to get the fuel fractions right and also don't think my ascent profile is quite right, I only manage to get to the engine's airbreathing temp limit at about 25km up in the atmosphere, which I think is a little low. I was just wondering if it's even possible EDIT: I know SSTO spaceplanes are pointless and impossible to build with current tech... but hey it's for fun that I'm trying!

At the moment, I am building a spacecraft which will do moon fly-by's and enter low moon orbits. The panel shows Food, Water and Oxygen support for ~53 days, but for Waste, WasteWater only 7, respectively 1 day. What happens if I stay in space longer than the supported 7 days ? Do I have to carry all the waste ?

Right after Christmas 2016, I made one Steam backup and one Windows 10 backup (that one by just copying the KSP folder and moving it into another folder on my desktop), then used the built-in Steam functionality to downgrade my game to 1.1.3 in order to install Real Solar System, Realism Overhaul, Realistic Progression Zero and all of the recommended mods using CKAN. What do I do now that KSP RSS RO RP-0 can be played on 1.1.3? How do I update the game? (I'm new here, so I'm being conservative on the formatting before I can develop a pattern.)

It was time to upgrade my PC, so I went for a Ryzen 5 1600 + Sapphire rx580 Nitro+ Limited Edidtion, and kept my Samsung 850 EVO I was and am playing 1.1.2, Modded with RSS+RO + essential mods + a few more. KSP on the new PC is just a folder copy from the old PC (same install). Game loading improved greatly, with about 9 minutes on the old PC vs 2:30 to 3 minutes on the new, but everything else feels almost the same... Same launchpad loading times, same frame drop on flying bigish rockets, etc. VAB is a bit more responsive, but everything else feels kind of same. I didn't try a stock install, only modded. My RX580 doesn't start the fans until it is pushed and start heating, and it never ever started the fans while playing KSP, and CPU was at 48C max temp. As if both CPU and GPU were not utilized at all... I also play ME Andromeda, which runs perfect with most settings on ultra high (as opposed to before, were it was straggling and glitching with the lowest settings) To the question. Is there something that I can do to have some improvement on performance on KSP? Some setting etc to utilize my new system better? Maybe newer KSP versions like 1.2 will run better? I keep 1.1.2 for MOD compatibility, as I will have to rebuild most of my rockets if I change KSP version, and I try to avoid it. I spent hours and hours on building and fine-tunning my rockets and editing cfgs, have loads of orbiting satellites, and i am terrified to the idea of starting over, due to some not updated mods that I currently use) ****IMPORTANT NOTICE: DO NOT COMPARE INTEL & AMD HERE PLEASE.

Hello everybody, I am here to announce the proud launch of TechTier. We are based around creating a realistic space program environment. We will include top of the line realistic launch times, conditions, physics, and of course rockets. For instance, say that today the temperature at Cape Canaveral is 78 degrees Fahrenheit, this is a nominal launch temperature if we had a launch set for today. We will be using extra realisticness by adding in launch timer and event callout. We will also be using others such as booster cams, (no floating cameras), occasional failures, and real development times for new rockets and technology. Any real world satellites or suggestions will be accepted if available with our current rocket capabilities. I am running a pretty packed version of Realism Overhaul to meet real world requirements. We primarily specialize in LEO station building, LEO or GSO orbits, as well as NASA related missions. I will mainly be launching from Cape Canaveral, but if required, I have KSC switcher for maximum performance. I will soon set up a post for real world or highly detailed satellite suggestions as well as, eventually, manned missions. While this is 100% for the fun of it basically, I will, to the best of my knowledge, explain the physics and reasoning behind my designs. I hope everybody enjoys this journey, and without further adue, enjoy! Link to my heroes who inspired me: http://www.spacex.com/

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.

I apologize for my english, i hope that what i wrote it's clear. Thanks for your time and your help.

I attempted to use CKAN to install RO with other mods that i like such as RP-0 and Lack's Stock Extention, 89-95 Mods total. My issue is that whenever try and make a plane/use wings is that they dont function, I cant adjust pitch yaw and roll, i don't get a center of lift, all i get is a blue circle hovering below my plane. I really wanted to make a plane so i could complete the X-Plane mission, But there may be a few mods clashing with one-another, Please help!

I want to share/store documents and plans I (and others!) make for interplanetary missions. I intend to start with basic/boring information, like ballistic coefficients, heat shield information, etc.that will be useful to see for planning a mission. I intend to draw from data of actual carried out or planned missions, but feel free to post information about missions you've carried out with the full RSS/RO/RP-0 stack in KSP 1.1 or 1.2. For starters, I've got this document which lays the ground for a Venus balloon mission. A heatshield is required to slow the craft down at Venus, of course, but the idea is that a balloon/probe combination would be great for gathering information from Venus. I also have the notion that using a balloon would be the best way to attempt to bring a probe back to Venus' orbit from the surface of Venus. Once the balloon & payload are up past most of the atmosphere, a rocket could be used to rise the rest of the way to orbit. https://spaceflightsystems.grc.nasa.gov/SSPO/SP/VenusUpper/Presentations/gage_VenusEntryBalloonsUAVs.pdf

Hello

I am very new to RO and RSS and when I am crafting my new rocket, it has negative mass and center of mass was well below the rocket. Picture 1 Picture 2 When launching, the rocket crash and clips with other parts.

Hello, I have TestFlight installed and screen shot of my very first rocket with the Aerobee engine. My Issue is the the Aerobee never burns for 50sec. It fails at about 10secs or 3.6km altitude every single time. I have doubled checked the fuel mixture and doesn't seem like an issue(see screenshot). I had the EngineGUI open and the Thrust/Drag ratio keeps dropping and the engine fails with the message "No more ignitions left". Is this is bug or a feature? I tried flying the same rocket multiple times hoping the failure rate reduces but it consistently fails at same point. So confused!! KSP: 1.2.2 RO: v11.4.1(Pre-release v2) TestFlight-Core: v1.8.0.0 Thanks

I have recently returned to KSP and was looking forward to the integrated telemetry and wanted to try the RO / FASA / Historical Contracts mods. After a few days playing with the available pre-release versions on GITHUB I seem to have everything working except for RealHeat (which appears to be abandoned?). The early game USSR craft seem to be a bit under powered and the Saturn V only has a TWR of .31. I've tried merging the pending pulls on FASA/RO GIT's but the mass and thrust are right (maybe not counting all the engines?). Anyway, I was just wondering if there is anybody else that wants to collaborate on getting RO working again, or should I just wait it out? Happy Landings! -Dead

I was wondering if anyone has built a successful STS in RSS/RO/RP-O game, I've been trying for around a month to get one to fly, orbit, and land with no success. I'm using KSP 1.1.3 since that was the last stable RSS/RO/RP-O build and I have a sweet saved game on it in the late 70s with a maned Mars base, large space stations around Earth, the moon, and Mars, orbiters around all the planets except for Pluto.

A bad one, i know but it's my first orbit in Real Solar system - Realism Overhaul - Realistic progression zero in early career (day 3). only first row of science unlocked.

Alright, so back in 2015, I got this game and had absolutely no idea what to do whatsoever. I got to the Mun, I landed on the Mun, but never returned. I did pretty well for someone who had a horrible understanding of physics. I went away from it for a few months and came back in fall of 2015 after learning a bit of physics and I was able to get to orbit, go to Minimus and land on Minimus and return. I soon after that went to the Mun though it was very overbuilt and after that went to Duna and back. (although this took several attempts.) I went off again after landing on Duna, Ike and Dres, to learn a bit of coding. I didn't get very far there but I plan to go back and start again and try to get further. But anyway, I came back to Kerbal after that and landed on Gilly, Eeloo, Jool's five moons, Eve and Moho and returned from all of them. I did this over a timespan of a few months since I started doing this a little over a year ago. I then downloaded OPM and landed and returned from both Tekto and Slate in two single manned launches. I then decided that landing on the rest of them would be tedious and take lots and lots of DV so I went back to stock and tried to build some colonies. I got a pretty nice Duna one, but then got so bored, that I took a tiny hiatus before coming back and downloading RSS. I got into orbit of Earth before downloading Galileo's Planet Pack and getting into orbit of Gael. I now was torn between playing in GPP, stock or RSS. I ended up going back to stock yet again, doing a challenge, the low mass Moho challenge to be exact, and then found out that I could have multiple installations of KSP. I ended up downloading RO on one of them, (the pre-release for 1.2) and then starting a little game there. This thread is the mission report from that save. Well sorry for boring you with my KSP story. This has been told many times but I just wanted to give you a bit of background to this playthrough. So here is the modlist since someone is going to ask. Here are my long-term goals for this playthrough. Manned return from the surface of the Moon, Manned return from the surface of Mars, (Possibly) Manned return from the atmosphere of Venus, A Colony on the Moon, A colony on Mars A LEO space station. Missions complete: LEO satellite: The first ever spacecraft launched into orbit around Earth. Tested the Rex booster. Outcome: Success. Engine bugged and the thrust came from right in front of the spacecraft instead of from the engine making it go out of control but in the end, I managed to get it into orbit. Rex was unable to get the approximately 1 ton spacecraft to LEO. Future modifications needed. Screenshots: Lunar probe 01: Was meant to be the first spacecraft to orbit the Moon. Tested the Rex heavy. Outcome: Failure. The Rex Heavy got it into LEO but barely had enough DV to start the Trans-Lunar Injection burn. The probe's engine unfortunately was pressure fed and the fuel wasn't pressurized. The engine never started. Screenshots: Lunar probe 02: The second probe sent to the Moon. Tested the Regina heavy. Outcome: Success. The new, bigger rocket, Regina got the probe into orbit with more than enough DV for the trans-lunar injection burn. After the burn was complete the spacecraft separated. Thanks to the pressurized fuel tank, the engine started up and although the probe had no signal, it was already pointed in the right direction and was able to start up the engine and get it captured into the Moon's orbit. The probe successfully entered a lunar orbit. Screenshots: Next mission: Manned Lunar Landing: This mission will mimic the Ares mission to the Moon instead of the Saturn V. The lander will be sent up with the transfer stage. Then the crew and orbiter will be sent up with the crew and dock to the lander. The Transfer burn will then complete the trans-lunar injection and then decouple. The orbiter will then use its engine to capture around the Moon. The lander will undock and land using its lower stage. The Kerbals will get out, plant a flag and then get back in. Yup pretty boring but it is always the accomplishment that matters. I plan to bring rovers on the next few missions. The lander's upper stage will then take off and rendezvous with the orbiter, transfer the Kerbals and supplies and then get ditched. The orbiter will then burn back to Kerbin and hopefully return safely to the ground. I do not know how Real Heat or Deadly Re-entry work. I just add a heat shield, a few drogues and regular parachutes since I do have passing out due to G-force enabled, and then just go. I believe I will try a manned mission just to LEO before doing this mission. Screenshots: But that's it for now. Fire
