  1. KSP Career Vlog

    So I have a youtube channel where I've been creating KSP content and figure I'd share it to the Forums. The point of my career is to make money and colonize the Kerbol system. I am playing with a few mods, but they are honestly negligible. I use MechJeb, Alarm Clock, Outerplanets, and this Landing Leg mod I found. I've documented most of my career in videos, with the exception of busy work like refueling and taking up easy routine contracts. Down below I'll post videos of my missions, testing, and crafts. It should be noted that there is no reverts allowed, except for when the Kraken intervenes. The videos are organized from recent at the top to old at the bottom. The recent ones are where you'll find my best KSP missions probably, not that the old ones don't have some good memories, but they mostly exist as documentation. Duna Science Launch: This video shows the launch of our reusable ship infrastructure. I'm not sure how well I like it. The booster is definitely good, but the ship will probably be changed as time goes on to make cargo easier to deploy. Right now we are just loading up the ship in LKO. There it will be refueled. The ship has the science lab for Duna. Minmus Lab In this video clip we land a second Minmus ship down on the planet, this one having a lab. From here we set up the basis of the colonies, having a refueling station and a lab. As we are starting to max out on science at this point, later bases will be more focused on habitation and refueling. Mun Cargo Vessel Return Here we see a demonstration of the Cargo Variant of our Reusable system returning from deploying a lab in orbit of the Mun. This was during the prototyping of the reusable infrastructure. Minmus Mission In a test of the updated vehicle we did a Minmus landing and return, and learned to change where we put our drag surfaces. Minmus Sat Early episode in our space program where we first unlocked the vector engines and made a nice booster stage. ProtoKais Mission Part 1 of one of our more daring missions when we were young with technology. That was a cheaper version of second stage re usability tests. Satellite Launch Here we can start to see the progression of our career as we launched satellites in the early stages of it. Lion Launch Vehicle One of our earliest rocket designs, good for basic satellites Career do or die Moment It was at this point in our career where this mission was the difference between failure and success. If we failed here we wouldn't have enough money to do another mission. First Ship to Orbit The first time we went to orbit
  2. Hi! I've got something new for y'all! Liquid Rhenium Solar Thermal Rocket The maximum temperature concentrated sunlight can heat a material to is 5800K. How do we approach this limit? We will describe existing and potential designs for solar thermal rockets. Solar thermal rockets The Solar Moth The principle of a solar thermal rocket is simple. You collect sunlight and focus it to heat a propellant headed for a nozzle. A rocket engine's performance is determined by its thrust, exhaust velocity and efficiency. A solar thermal rocket's thrust can be increased by sending more propellant through the nozzle. Its exhaust velocity can be increased by raising the propellant temperature. Doing either required more power, so more sunlight needs to be collected. Efficiency will depend on the design. The main advantages of a solar thermal rocket are its potential for high power density, high efficiency and high exhaust velocity. Collecting and heating with sunlight does not need massive equipment - unlike solar electric spacecraft that need solar panels, extremely lightweight reflective metal films can be used. A heat exchanger above a nozzle is compact and masses much less than the electrical equipment and electromagnetic or electrostatic accelerators a solar electric craft uses. Radiators are not needed either, as the propellant carries away the heat it absorbs with it. Put together, a solar thermal rocket can achieve power densities of 1MW/kg while solar electric craft struggle to rise above 1kW/kg. Sunlight would follow the same path as the laser beam here. As the sunlight is being absorbed by a propellant and expanded through a nozzle, there are only two energy conversion steps: sunlight to heat, then heat to kinetic energy. The first step can be assumed to be 99% efficient. The second step depends on nozzle design, but is generally better than 80%. Exhaust velocity will be determined by the root mean square velocity of the gas the propellant turns into. The equation is: Exhaust velocity: (3 * R * Temperature * 1000 / Molar mass ) ^ 0.5 Temperature is in Kelvins. Molar mass is the average g/mol value of the propellant at the temperature it is heated to. R is the molar gas constant, equal to 8.314 J/mol/K. For the very hot gasses we will be considering, we can assume complete dissociation of all molecules. H2 (2g/mol) will become atomic hydrogen (1g/mol), water (18g/mol) becomes a hydrogen-oxygen vapor (6g/mol) and so on. Low molar masses are preferred, with the best propellant being mono-atomic hydrogen unless other factors are considered. These advantages are all the critical elements that allow for travel throughout the inner solar system without requiring vast quantities of propellant. This means smaller spacecraft and lower travel times. Heat exchangers and exhaust velocity The limiting factor for solar thermal rockets is how hot they can heat the propellant. Directly heating the propellant is a difficult task. The lowest molar mass propellant, hydrogen, has terrible absorption. For all practical purposes, it is transparent to sunlight. Seeding the propellant with dust particles that absorb sunlight and heat the hydrogen indirectly through conduction has a major catch: the dust particles get dragged along by the hydrogen propellant flow and increase the average molar mass. A single millimeter-sized carbon dust particle in a cubic meter of hydrogen increases the molar mass from 1g/mol to Indirect heating involved using a heat exchanger as an intermediary between the sunlight collected and the propellant being heated. So far, designs have required the use of a solid mass of metal that is heated up by concentrated sunlight. The propellant is run over the metal, or through channels in the metal, to absorb the heat. Tungsten is often selected for this task, as it has a high resistance to heat, is strong even near its melting point and has a good thermal conductivity. Testing a Hafnium/Silicon Carbide coating. More modern designs make the most of the latest advances in materials technology to allow for higher operating temperatures. Carbon, notably, stays solid at temperatures as high as 4000K. Tantalum hafnium carbide and a new Hafnium-Nitrogen-Carbon compound melt at temperatures of 4200 and 4400K respectively. However, looking at our exhaust velocity equation, the limits of modern materials technology will only provide a 21% increase over common tungsten. This is the reason why so many propulsion technologies that rely on exchanging heat between a heat source, such as a nuclear fuel or a laser beam, and a propellant using a solid interface are said to be 'materials limited' to an exhaust velocity of 9.6km/s with tungsten, or 10km/s with carbon. THC or HNC would allow for an exhaust velocity of 10.5km/s. This is the deltaV equation, also known as the Tsiolkovsky rocket equation: DeltaV = ln (Wet mass / Dry mass) * Exhaust Velocity Wet mass is how much spaceship masses with a full load of propellant. Dry mass is the mass without any propellant. The wet to dry mass is also referred to as the 'mass ratio' of a rocket. We can rewrite the rocket equation to work out the required mass ratio to achieve a certain deltaV using a rocket engine's exhaust velocity: Mass ratio = e ^ (DeltaV required/Exhaust Velocity) 'e' is the exponent 2.7182... in simpler terms, the mass ratio increases exponentially as the deltaV required increases. Or, put another way, the mass ratio required decreases exponentially as the exhaust velocity rises. It is critical to have a higher exhaust velocity for rapid space travel without requiring massive rockets and towers of propellant. You might also have noticed that 'solid' is a keyword up to this point. Why must the heat exchanger remain solid? Liquid Rhenium There is a method to achieve the true maximal performance of a solar thermal rocket, which is heating up the propellant as far as it can go. This is incidentally the temperature of the surface of the sun (5800K). At this temperature, hydrogen propellant reaches an exhaust velocity of 12km/s. A rare, silver-black metal. Rhenium is a rare metal with a surprising number of qualities, one of which is a very high boiling point. Rhenium melts at 3459K but remains liquid up to 5903K. The trick to achieving higher exhaust velocities is to use a molten heat exchanger, specifically liquid rhenium at a temperature of 5800K. Rhenium is also very stable and does not react with hydrogen even at high temperatures, which is something carbon-based materials struggle to survive. It has already been considered as a heat exchanger, in solid form, by NASA. Here is a design that can use liquid rhenium as a heat exchanger: The diagram is for illustrative purposes only - a functional schematic would be more detailed. Here is an explanation for each component: Solar collector: A very large, very lightweight reflective film based on solar sails that can collect sunlight and focus it through a series of lens onto the heat exchanger fluid's inner surface. Rotating drum: The drum's inner surface contains a liquid heat exchanger. The outer surface is actively cooled. The drum is dotted with tiny channels that allow the propellant to enter the liquid from the bottom and bubble through to the top. It is made of Tantalum-Hafnium Carbide. Fluid surface: The fluid here is liquid rhenium. Its surface is heated to 5800K by concentrated sunlight. The lower layers nearer the drum holding the fluid is cooler. The centripetal forces hold the fluid in place Pressure chamber: The rotating gas mix gets separated here. Dense rhenium vapours fall back down, hot hydrogen escapes. Bubble-through heating: The rotation induces artificial gravity, allowing the hydrogen to heat up and rise through the denser rhenium. As it rises, it reaches hotter layers of the fluid heat exchanger. At the surface, it has reached 5800K. Small bubbles in direct contact with the rhenium allows for optimal thermal conductivity. More detail below. Active cooling loop: liquid hydrogen from the propellant tanks makes a first pass through the drum walls, lowering the temperature below the melting point of THC. It emerges as hot, high pressure gaseous hydrogen. High pressure loop: The heated hydrogen is forced through the channels in the drum. It emerges into the fluid heat exchanger as a series of tiny bubbles. Here is a close up of the drum wall, which contains both active cooling and high pressure channels: The configuration displayed above allows the hydrogen to enter the basin bottom at 4000K, then be heated further to 5800K before being ejected into the pressure chamber. If higher quantities of liquid hydrogen for active cooling are used, the drum and high pressure channel temperatures can be lowered to 3800, 3500, 3000K or lower. This pebble-bed nuclear thermal reactor has most of the components of our solar thermal rocket, except that instead using pebbles of nuclear, fuel, we use a liquid rhenium bed heated by sunlight. If the liquid hydrogen active cooling cannot handle the full heat load, radiators will be needed to cool down the drum below its melting point of 4215K. Thankfully, these radiators will receive coolant at 4000K. Their operating temperature will be incredibly high, allowing for tiny surface areas to reject tens of megawatts of waste heat. Electricity can also be generated by exploiting the temperature difference across the radiators' entrance and exit flows, and at very high efficiency. Operation The design is a Rotating Drum Fluid Heat Exchanger Solar Thermal Rocket (RD-FHE STR). It allows for hydrogen propellant to reach 5800K and achieve the maximum performance of a Solar Thermal Rocket. Liquid rhenium does not boil at 5800K, so it remain liquid and can be held inside the basin by simple centripetal forces. Vapor pressure of rhenium at 5800K (0.was determined to be low enough for our purposes. A surface of rhenium exposed to vacuum at that temperature would lose 0.076g/cm^2/s, or 762g/m^2/s. It is unknown how much centripetal force affects the loss rate of rhenium. The pressure chamber would operate at several dozens of atmospheres of pressure, which is known to increase the boiling point and reduce the evaporation rate of fluids. The same techniques used in Open-Cycle Gas Core nuclear reactors to prevent the loss of uranium gas can be applied to reducing the loss of rhenium vapours. At worst, the rhenium heat exchanger loses 0.76 kg of rhenium for square meter per second of operation. Looking at the designs below, the mass flow rate is measured in tons of hydrogen per second. This is a ratio of 1000:1, to be improved by various rhenium-retaining techniques. It should also be noted that rhenium is a very expensive material. A tungsten-rhenium mixhas very similar thermal properties and is much cheaper. Sunlight at 1AU provides 1367W/m^2. A broad-spectrum reflecting surface such as polished aluminium would capture and concentrate over 95% of this energy, so more than 1298W would be available per square meter. Solar sails materials such as 5um Mylar sheets are preferred, massing only 7g/m^2. More advanced materials technology, such as aluminium film resting on graphene foam, might mass as little as 0.1g/m^2. The 'Solar Moth' used inflatable support structure for its mirrors. Based on data for the Solar Moth concept, we have estimated that a solar thermal propulsion system can attain power densities of 1MW/kg. So, each square meter of collector area will require another 1.29 grams of equipment to convert sunlight into propulsive power. Performance Robot Asteroid Prospector We will calculate the performance of two versions of the RD-FHE STR. The first version uses modern materials and technologies, such as a 7g/m^2 Mylar sheet to collect sunlight and a 167kW/kg engine power density. The second version is more advanced, using 0.1g/m^2 sunlight collectors and a 1MW/kg power density. Modern RD-FHE 5 ton collection area => 714285m^2 927MW of sunlight focused onto the drum. 5.56 ton propulsion system Exhaust velocity: 12km/s Thrust: 123.4kN (80% efficiency) Thrust-to-weight ratio: 1.19 Overall power density: 87kW/kg Advanced RD-FHE 5 ton collection area =>50000000m^2 64.9GW of sunlight received 64.9 ton propulsion system Exhaust velocity: 12km/s Thrust: 10.8MN Thrust-to-weight ratio: 15.75 Overall power density: 928kW/kg The principal argument against solar thermal rockets, that their TWR is too low and their acceleration would take too long to justify the increase in Isp, can be beaten by using very high temperatures and very low mass sunlight collectors. For example, a 50 ton propulsion system based on the modern RD-FHE STR design, would be able to push 100 ton payloads to Mars (6km/s mission deltaV) using only 97 tons of propellant. It would leave Earth orbit at a decent 0.24g of acceleration, averaging 0.32g. The departure burn would take only 20 minutes. Using the advanced version of the RD-FHE solar thermal rocket would allow for a positively impressive acceleration of 3.1g. With 12km/s exhaust velocity, multiple missions that chemical rockets struggled to do with low-energy Hohmann transfers can be avoided. A chemical rocket such as SpaceX's BFR might achieve an Isp of 375s, which corresponds to an exhaust velocity of 3.67km/s. It would need a mass ratio of 5.13 to barely produce enough deltaV for a Mars mission. Earth to Destination. If our solar thermal rocket is granted the same mass ratio, it would have a deltaV of 19.6km/s. This allows for a Mars mission to be completed in under two months (10km/s departure, 9km/s insertion). It is also enough deltaV to reach Jupiter with a single stage. Other benefits include a vast reduction in the propellant-producing infrastructure needed to supply orbital refuelling depots and the ability to land on Mercury. Alternative versions: Blown hydrogen: Instead of bubbling hydrogen from the bottom of the liquid rhenium basin, hydrogen is blown into the pressure chamber from the top. It is heated by simply passing over the fluid heat exchanger. The advantage is that the rotating drum does not have to be riddled by microchannels, allowing it to be stronger and rotate faster, which would reduce rhenium losses, and also accept a higher rate of active cooling by leaving more room for liquid hydrogen channels. Another advantage is that there is less chance of hydrogen bubbles merging and exploding in showers at the surface, dragging along rhenium as they escape. The disadvantages is vastly reduced heat conduction rate between the rhenium and the hydrogen. This would require a long and thin pressure chamber to increase the time the hydrogen stays in contact with the rhenium, potentially making the propulsion system heavier than it needs to be and forcing sunlight to enter the chamber at very acute angles. ISRU propellants: Instead of hydrogen, other gaseous propellants might be used. Nitrogen is a good choice, as it is inert and only reduces the exhaust velocity by a factor 3.7 compared to hydrogen. Powering a hydrogen extraction process on Mars requires huge areas of solar panels. Nitrogen is easily sourced from Earth's atmosphere by gas scoops. Other options, such as water or carbon dioxide, are also viable and available on other planets. The advantage is that non-hydrogen propellants are easy to contain and are much denser than hydrogen, so their propellant tanks can be lightweight and small. They are easily sourced and only need to be scooped up and filtered, unlike hydrogen that has to undergo electrolysis. The disadvantage is that there propellants cannot serve as expandable coolant for the rotating drum. A radiator using a closed gas loop is necessary - helium is a likely candidate. This adds mass. A lower exhaust velocity also removes the principal advantage the RD-FHE STR has over other propulsion systems.
  3. Kerbal space program has been around for a while and there is still no official online multiplayer? Why? This feature is screaming to be added. For example an online sandbox mode where you can play with friends. Not only would this allow current players to enjoy this great game even more, it would generate the company more money. More people would be asking their friends to buy the game so that they can play online with them. So what is up with this?

  8. Sci-Fi Comics Discussion Thread

    We've all seen and read them, so why not share them! I'm sure that you have some copies of sci-fi comics lying around somewhere, or have been inspired by them at some point, and you're not alone (I was five after reading a Star Wars comic, and put myself in a cardboard box, trying to be a Star Destroyer). Besides, it's fun to see what they imagined what we'd have in the 21st century (hovercars, rayguns), and what we actually have (rising tensions between countries, threats of nuclear war, etc). So if you've seen some old sci-fi comics around, then why not tell me about them!
  10. My Space Programme

    Hello and welcome to meh little space programme! Here I will be weekly uploading about my space program. Maybe I should tell you about my status as a space program. Ok, I'm not a real space program owner but hey, maybe one day I will be! Ok, back to the topic, I live on a farm with a airspace that VERY rarely planes pass across.this kinda means that for my rocket launches, I will not need to have airspace cleared or anything. so that means I won't really have a time restraint, meaning I won't have to finish a rocket on time. Also, because I live on a farm, many chemicals are available (because they are used for put killing), but this doesn't necessarily mean they are perfect for using rocket fuel. Also this thread is linked to my other thread: Ok, now lets cut to the chase, and I will start posting my status as a space program! PROLOGUE Back a few months ago I built these mini match rockets and they, because of limited time, flew 30 feet(only half of the expected 60 feet). I then, in the afternoon of that hot day, built these bottle rockets flying 40 metres! (80 feet?) they were made of soap, water and local air(dat stuff you breathe in). We did so many launches that I could not even count!!!(I'm guessing like 80 launches or something) then we started experimenting with petrol! *evil grin* to put it, the petrol we used was not explosive, between it came out it burnt everything it lands on because of the Bunsen burner used to light the petrol up. After this I went into a period of long research... August 13th So today I was looking in the ol' PVC and adapters parts and I found the perfect piece for a hybrid rocket motor! Then I burnt one end with a Bunsen burner until it was alight. then I quickly used an O2 tank as an oxidiser which then created a very hot exhaust... The flame actually turned blue at a point too! I think hybrid rocket motors are the way to go if you are beginning a space programme!!! Sorry I’m discontinuing this ...
  12. Space Odyssey

  13. Dust storm Chapter 2-VOYAGE Against the slowly stopping wind... Against the freezing night...Against the weakness, kerbals go.. Bob looked around the rover.. Jeb was resting, looking into the void-dark sky... Bob got closer to observe the rover. To his upset he saw nothing valuable. Bob pushed the rover really hard! And then the wheels began to work! The happiness of accomplishment overwhhelmed Bob and Jeb.. Rover went on, automaticly.. Rover stopped. And then, Jeb suddenly got off the rover, it seems like he got better, Bob didn't want ot question that. Probably because Bob was doing something else. Kerbals went sleeping.. But then, suddenly Jeb woke up at the Dunian midnight. Jeb's personality began to crack under the pressure of the situation, much to Bob's surpise.. Kerbonauts finally found their calm, and began sleeping, dreaming about their homes.. Eearly,early in the morning. Morning starts with a proper routine, even in the extremal situation.. Crossing the remaining 9km was not easy, especially for Bob.. Finally, after a long time reaching the base, kerbals, or kerbal, to be clear, saw the base in the distance.. They have reached the safety for now, but that is just for now.. --------------------------------------------------------------------------------------------------------------------------------------- Song: The second part is reached! Our little voyagers have reached the base! Awaiting trials of the future! Now, i sincerely ask @Vanamonde, not to merge this one with the previous one. I want to merge it after i will be done with the third part. I will send a message!
  14. DMP dogfights in space?

    I've never played the game with the DMP mod so please forgive me if I'm way off here... I've been looking at several you tube videos from people using dmp and i never find any cool dogfight scenes, which would in mho be one of the great things to experience while using this mod. also, i can tell that dmp can be rather laggy and shaky while planes are in the atmosphere. so that could explain why dogfights a no go with the current version of the mod. I've heard that in orbit, the movement of ships is less laggy and shaky with DMP. so wouldn't it be possible to perform enjoyable lagless dogfights in space? the dynamics and fighting mechanics would probably be pretty different from a dogfight in atmosphere but i guess it could be fun? right? has anybody tried this before?

  19. Could We Terraform Mars???

    Well, for so many years, science fiction writers and scientists have dreamed of terraforming a planet. I think it just might be possible, but not for a VERY long time. (At least 50 years) How would we do it? For a start, we would have to increase the pressure of Mars's atmosphere. After that, we would have to increase the temperature of Mars by quite a bit. Of course, we would have to get water. For that, we would melt the ice caps, which would give us water and Co2. Soon, we would have to slowly begin growing algae and other oxygen releasing plants in greenhouses, which in turn would put the Oxygen into the atmosphere. However, bad news for Terraforming: After tens of thousands of years, we might have a breathable atmosphere to live in. What are your thoughts? Do you agree?
  20. HI I have a problem with my space shuttle when I going pack to the space center. When I enter a point around 40km to 30 km. I lose ful control of the shuttle and it is spinning and hurling. I have been using this shuttle for a very long time and never had a problem whit reentry. What are wrong and how do I fix it??
  21. Interstellar War

    Sol and Alpha Centauri duke it out in the 31st century. No other colonized systems because magic radiation stops them. No FTL. Systems are completely colonized and exploited. War is to the death. How is the war fought? Who wins?

    Hey, EDIT: Tell me what do you use more for browsing? Mobile phones or desktops/laptops/tablets? I will optimize site accordingly. I've made a website called . This site will be uploaded with beautiful images from space engine. Tell me what do you think about the site and write in the comments(on the site). I'll regularly post an image daily . I DON'T OWN SPACE ENGINE AND DIDN'T CONTRIBUTE ANYTHING.
  23. Intro: Since I got a new computer, I started a new game. This one is a large-scale space race between the KAP/KSP (US) and the C7 Aerospace Division (USSR). There will be several races such as first in space, orbit, landing on the Mun, first to land on a planet, etc... I have the Kerbin-Side mod installed. Since it's only updated for 1.0, it only has 1 other launch site, Round Range, which has a launchpad, runway, and helipad. Other mods installed: MechJeb Chatterer Scatterer Planet Shine OPM (soon) The Near-Future Series KAS KIS Kerbal Engineer Tweak Scale Chapter 1: Post-War It was five years after the Kerbin War. Nations had grown stronger, torn apart, or obliterated all together. The two strongest nations, United Kerbin (UK) and the Kerbal's United Republic (KUP) were the leading nations in aerospace, fighting alongside each other in intense aerial battles until the end of the War. Relations slipped a bit at the end of the War and cooperations with the two nations ceased. They set their Air Force funds towards world exploration and developing more advanced aerospace technologies. The two agencies were called the Kerbal Aerospace Program (KAP) and the C7 Aerospace Division. They had the most advanced aerospace technologies in the world, proven by their unreal amounts of wins in aerial battles in the War, only losing an average of 20 planes for every year the War raged. After the War, a total of 15 countries signed a pact against war, outlawing any means of war including the use of fighter planes. 2 of those countries were UK and the KUP. After the ratification of the KAP, they went to work on achieving the goal of developing the world's first supersonic aircraft. Development had started before the program was even put in place, so testing and building didn't take long. On Day 14 of Year 1, test pilot Valentina climbed into the Supersonic (SS)-1, a modified SX-4 jet fighter plane. It was fitted with an new J-33 jet engine to propel it faster than any other manned aircraft before. The engine was activated and the plane started to roll forward on the runway. The plane pitched up off the runway, building up speed. A little after 30 seconds, the aircraft reached 342 m/s, the speed of sound. It accelerated past the speed of sound for a couple of seconds. Valentina then pointed it back towards the Kerbal Aerospace Center (KAC). It landed on the runway and rolled to a stop. Mission results: Success; Successful application of a new jet engine to send a modified SX-4 fighter plane past the speed of sound. Meanwhile at the C7 Aerospace Facility (C7 AF), a top-secret technology was being developed: a rocket-powered bomb, or missile called the Rattlesnake. This was being developed by order of the KUP's government for protection against another war. This was directly against the pact signed by the KUP and 14 other countries, however. To keep it unknown from the rest of the world, it was to be test-launched towards a remote area north of the C7 AF. The missile consisted of a nuclear warhead like that of what was used by the KUP to end the War on top of a tall rocket stage. After the trajectory would be set by the rocket stage, the warhead was to be jettisoned, coasting across the sky until it reached its target. As it decoupled, for tiny solid-fuel motors pushed the rocket stage away from the warhead so a premature detonation would not occur. On Day 18 of Year 1, the missile was ready to be launched on its first test flight. It was fitted with a dummy warhead so that no noticeable explosion would give way to the secret C7 project. The engine ignited and the four launch-clamps let go of the rocket. It ascended quickly into the air and pitched north. It made its way over the mountains completely surrounding the C7 AF and towards its target site. The engine stopped even before all the fuel was depleted as it had reached its target. The warhead was jettisoned and the four separation motors fired. The rocket stage was to impact the ocean just north of the warhead target site. The warhead tumbled around in the air until it hit the ground with a small explosion. The rocket then impacted into the ocean. Mission results: Success; Successful test of the Rattlesnake Intermediate-Range-Ballistic-Missile Shortly after the first successful test of the Rattlesnake IRBM, the KUP government ordered another test. A new missile was built and prepped for launch. On Day 27 of Year 1, another Rattlesnake was placed on C7's launchpad. The engine ignited, the launch-clamps were released, and the missile lifted-off into the air. It pitched south-west of the C7 AF and over the mountains towards its designated impact site. During flight, it gained too much speed and started to burn up. Unexpectedly, the whole assembly exploded mid-air. It happened that it exploded over a small town on the mountainside south of the C7 AF. Word was spread about how a large pencil-like object flew over the mountains from the C7 AF with smoke trailing behind it and exploding over the town. However, most of the world took it as a rumor as the C7 AF was government-run by the KUP, a nation which signed the international pact against war. Mission results: Failure; Failure at further testing of the Rattlesnake IRBM The KAP realized that if there was any way of reaching space, rocket power would have to be utilized. Rocket power had been used by engineers for moving heavy objects across work sites, and those had only been solid-fuel engines. It wasn't until recently that the C7 Aerospace Division announced they had made the first successful liquid-fuel rocket engine. They didn't say what it was being used for, only that a successful static-test had been conducted. Now that the KAP knew it was possible, it was time to start developing one to fly high into the atmosphere. On Day 33 of Year 1, the KAP placed the new Pulse liquid-fuel rocket on a launch stand. It was a small rocket that was stabilized by canted fins to send it into a spin. A pre-programmed computer was to turn the engine on and separate from the stand during launch. The time had come and the computer turned the engine on and the rocket separated from the launch stand. It started to spin slowly at first, but picked up rotational speed within seconds. The engine burned until it ran out of fuel. The apoapsis was determined to be around 27 kilometers high. The rocket coasted to the apoapsis and started to fall back to Kerbin, crashing into an unpopulated area west of the KAC. Mission results: Success; Successful test of rocket propulsion and spin-stabilization After the close-call of getting caught violating the international pact, C7 decided to develop a supersonic plane like the KAP as a side-project to cover up the Rattlesnake tests. It was loosely based off the KAP's SS-1 but mixed with the KUP's Y87 fighter jet. It included two air intakes opposed to the SS-1's single intake. On Day 42 of Year 1, the Soundwave was ready to fly. KUP test pilot Verette was to pilot the mission. The plane took off from the C7 AF's runway and flew east, breaking the speed of sound before it reached the edge of the mountain range. It then started to fly back towards the runway. As Verette was flying back, she failed to gain sufficient speed, ending up crashing onto the edge of the runway. The cockpit and Verette was recovered in good condition. Mission result: Partial success: Successful testing of a supersonic plane to cover up the Rattlesnake program In response to C7's partially-successful flight of the Soundwave 1, another flight of the SS-1 was authorized. This was to test maneuvering at supersonic speeds. On Day 47 of Year 1, Valentina again took off in the SS-1. She lifted off the runway and quickly broke the sound-barrier. She practiced several maneuvers, pulling upwards of 10 Gs. She maneuvered back towards the KAC still at the speed of sound, eventually landing successfully. Mission results: Success; Successful testing of supersonic maneuvers C7 had made several precautions for the next test-launch of the Rattlesnake. What they didn't know that spies were stationed on the mountain range to look out for the rumored missiles. On Day 48 of Year 1, the third Rattlesnake IRBM was launched. It flew north-west over the mountain range, right in the spies line of sight. To stop it from exploding mid-air, the engine was throttled down after it broke Mach 3. However, the electric charge in the probe core ran out, causing the engine to shut off and the missile to be short of its target site. The warhead also could not be jettisoned. It crashed in a lake south-east of the target impact site. Mission results: Failure; Failure of testing the the maximum range of the Rattlesnake After C7 and the KUP government was caught with an act of war, the other 14 nations that signed the pact banned C7 from launching missiles. They would, however, allow them to utilize the missile technology for peaceful uses such as space exploration. As a result, C7 found that it would allow a perfect opportunity to challenge the KAP. The challenge was to send a rocket into space before the other program does. The KAP accepted. After the new challenge between the two nations and aerospace programs was finalized, the deal was sealed by a flight by the KAP with its new SS-2 and a second flight of C7's Soundwave 1. The SS-2 was an SS-1 equipped with two side-boosters that allowed it to approach Mach 2, but it came just short of breaking that barrier. The second flight of the Soundwave 1 saw its first successful landing. To be continued...
  24. (Poetry)

    Bright high sun… Rotten surface… And deep craters.. But it is time to leave now From this fried brown planet The Moho Deep oceans ,craters Those heavy rainy clouds And infinite flatlands around Still standing still un explored The magnificent purple planet That pulling eyes to be watched The Eve The great blue dot Fading In green of the trees The oceans full of water and ice Which are standing by to be crossed The Kerbin Distant wander point Full of dread and red Watching victims of pull to be faint Great wisdom of dead Tracing pale steps of remains… The Duna Yeah im bad at poetry...But hey its an a attempt and im Russian and im very bad at english!
  25. Find me on KerbalX Hello everyone, here comes a terrible creation which had been sleeping for some time in the VAB and was about to be totally forgotten, the X-26A Eos. The project was born some times ago of the desire to make a small craft inspirited from the U.S. Space Shuttle system but having no more than the Mk1 size for its parts. Named after a Greek Titan and goddess of the Dawn, Eos was in my mind the symbol of a "new" way to build tiny shuttle... and I should have called her Hecate as she gives me so much troubles but the name was already taken. Originally she was conceived to be a super cheap Space Shuttle and easy to access in a new career. For it the boosters were made of Thumper, but they were absolutely incapable to kick her to a good altitude before running out of fuel. 6, 8 even 9 Thumper offset into each other on both sides still were unable to made it... and the low launch cost which was one of the reason supporting the project just explode (it did reminds a true story). So absolutely disappointed I opted for the Kickback and a total remodeling of the craft, changed the vertical stabilizer, placed more fuel inside the Orbiter. This made it more light and performant but still a test flight was needed... The climb is surprisingly smooth, the whole system being just a bit sensitive during the SRB last seconds of operation. Once jettisoned the orbiter and its External Tank recover their good control. The main problem appeared once close to the circularization altitude. The O.M.S imitation is consisting of just two Spark small rocket engines, those are totally underpowered for the mass of the orbiter even to start the maneuver about 2 minutes before the T time. The unique solution being to keep the E.T and start the maneuver with S.S.M.E Thud. For an Apogee of 140 km those are absolutely able to complete it with even some fuel still available in the tank, so I used to shut them down and eject the tank when just a 100 m/s are still needed and complete the maneuver with the O.M.S. At this point around 900/950 m/s of dV are still available. (Four Sepratron will ensure a quick clearance off the fuel tank) Once in orbit at 140 km the target was the traditional space station orbiting at 200 km : The whole docking maneuver is simple with four RCS pods being placed around the CoM. Then I don't know why but the X-26A remained abandoned for almost a year before finally returning to on the surface. Once again I overshot the KSC. The unique solution was to land on the old island airfield. Finally, what was supposed to be a simple system to ensure the transport of four souls for a very low price became a real luxury, costing more than 50 000. But it remains fun to control.
