  1. The OP reserves the right to post whatever and whenever he wishes. Don't worry, I'm going soon Jeb, Bill, and Bob descend the ladder to begin work on the surface of the plains. After collecting contingency samples, they proceed to the cargo lander and deploy Nerva 2, their rover for this mission. They then unpack the cargo boxes and load the SEP and drilling components into the rover's cargo locker. The first piece to go up is the power station, which uses two RTGs to provide electricity to both Aurelian 2 and the drilling stand. During the day, Aurelian's solar panels will also be used to provide power for the drill. The power station is then plugged into the cargo lander, which is then connected to Aurelian 2, allowing the crewed lander to receive power at night. Another EVA will be made shortly before takeoff to disconnect the pipes. The drilling stand and its collection tank are next set up and attached to the power grid. It will be activated by remote control after the EVA. Unfortunately, after this things begin to go horribly wrong. Nerva 2 accidentally hits a small crater and flips over, with Jeb inside. He spends the next few minutes trying to right the vehicle but eventually has to evacuate and perform the rest of the EVA on foot. Unless Nerva can be flipped back upright the planned exploratory traverses will have to be cancelled, as the nearby objectives are all too far to be reached on foot. Anyway, while Jeb is working on the rover, Bill and Bob assemble the SEP. This one is a much more simplified model than the one deployed on the last mission. Instead of a bulky high-gain antenna dish, it will simply use Marius as a relay to return data to Kerbin, and it will be plugged into the power station to keep it running after dark. Having finished the day's construction and unable to perform the planned trip to a nearby crater, the crew begins heading back to Aurelian for a rest. However, at this point, the gravest disaster of the mission strikes without warning. Bill Kerman falls over and appears seized by the Kraken, which slams him into the ground, killing him instantly. The crew had planned to perform a few more chores outside, namely setting up the landing site's flag and photographing the area, but in the wake of Bill's accident the flight director swiftly aborted the EVA. Jeb now faces a difficult decision; whether to attempt to right the rover and continue the mission or to wait until the first available opportunity and perform an abort to orbit. Without the rover the main goals of the mission are unachievable, and without a third crew member the risks of exploring the area, especially on foot, are increased significantly. It certainly seems that the mission is cursed, and morale has plummeted, both on the surface, in orbit aboard Marius, and back on Kerbin. Bill's death is being kept a secret from the general public for the time being, while mission control and the crew work the situation and develop a course of action. Interestingly, my computer also crashed to a bluescreen of death immediately after boarding Aurelian 2, so I'm beginning to wonder if some higher power just wants me away from this spot...
  2. Aurelian 2 undocks from Marius to begin its second mission to the surface. This expedition is crewed by Jebediah, Bill, and Bob, the same crew who also rode the first Scipio spacecraft into orbit. PDI is initiated over the landing site, at an altitude of approximately 5,000m AGL. Once pitchover is complete, Jeb takes partial-manual control of the spacecraft, trusting the flight computer to control orientation while controlling the throttle himself, while making occasional corrections to the computer's heading. Only a few minutes after PDI, Aurelian 2's contact probes scrape the surface of the Mun for the second time in its life. SE3's mission necessitated a much closer landing to the cargo lander than its predecessor's, because the crew will need to connect both landers with fuel pipes and electrical lines to facilitate the drilling and refueling operations. After a short rest, the crew will begin EVA1, in which they will assemble the SEP, power station, and drilling stand.
  3. I don't think that it would be all that useful to use Marius as a refueling stop for interplanetary ships instead of simply launching directly from Kerbin. The fuel I save would be negligible, considering that I would first need to travel to the Mun and rendezvous with Marius which costs more fuel. Additionally, I would then have to perform my planetary ejection burn from the Mun's SOI rather than Kerbin's, which means I could not make as much use of the Oberth effect to propel me along, should I choose to do so. In addition, the fact that I'm orbiting a body which itself is orbiting Kerbin, which is also moving in its own orbit means it will be much more complicated to calculate and achieve an ideal ejection angle, as I would have to wait for the Mun to approach the proper point in its orbit before departing, potentially giving me a much shorter time window in which to launch a spacecraft. In short, my fear is that I would end up using more resources and go through more trouble than it's worth to simply top off an interplanetary ship's fuel tanks when I could simply take slightly more fuel at the start. It's an interesting possibility, but not really one that I plan on exploring as of yet. To be fair though, manned interplanetary missions are still quite far away in my roadmap, so maybe my viewpoint will change between now and then. Anyway, make sure to post some pictures when you get your own base up and running, I'll be looking forward to seeing it!
  4. Surface Expedition 3's cargo lander has finally launched, following repeated delays concerning the final payload. The changes made include the addition of a small refinery to allow resource sampling, as well as the replacement of the solar arrays originally intended for this mission with RTGs, to facilitate operations in the lunar night. The launch was pretty normal, nothing new or interesting to show. Unlike Surface Expedition 2, I have no pinpoint target in mind, but rather a large swath of land containing a bountiful resource pocket, just north of the Mun's equator on the middle of the near side. To help guide myself during descent, I used the Polybius scanning probe, still in orbit around the Mun, to lay down two KerbNet waypoints surrounding what appeared to be the flattest land in the region, to mark the ends of a target ellipse, for which I would aim with the cargo lander. The actual landing site turned out to be just south of the light blue marker. Cargo-2 passing above the landing site just after arriving in Lunar orbit. One orbit later Cargo-2 begins its powered descent, aiming for the plains marked out by Polybius's waypoints. As it turns out, the land is pretty good for landing, almost perfectly flat, but also bordered by craters which may offer interesting exploration opportunities. Cargo-2 is now safely on the surface, with its drilling and refining machinery ready to be unpacked by the landing crew, which should be arriving within the week. Until then Cargo-2 wait on the surface, doing with it can with its onboard cameras to inspect the site. Pending the successful conclusion of this surface expedition, I plan to begin development of hardware meant for manned missions to Minmus. Although a base there would be less practical than on the Mun, its distance from Kerbin allows ample opportunity to experiment with long-duration flight in deep space. A new version of Scipio specially intended for deep space missions such as this is under development, as well as a new launcher capable of lifting it to Minmus. Instead of an orbital module, this Scipio Block III will have a new Mission Module, which will be stored in the fairing underneath the spacecraft during launch and retrieved once in orbit. It will be larger than the current Orbital Module and will provide much more utility in deep spaceflight. However, the launch schedule is still clogged with Lunar missions, as well as new modules for Marius, and no flight to Minmus is planned in the short-term.
  5. I don't know, I don't particularly mind crashing ships on the far side of the Mun, it's not hard to do.
  6. Finally back into the swing of things after my move to Huntsville, and I'm still managing to find chances here and there to play KSP The fuel tanker has been emptied and discarded, it will be deorbited on the far side of the Mun, just like every other unmanned supply ship sent to Marius. Meanwhile, the next landing crew has launched from KSC, aboard Scipio 6. Unlike the previous mission, this crew has launched before their cargo lander, due to last-minute payload changes. Scipio 6 will dock to Marius and its crew will help man the station for the next few weeks while waiting for their cargo shipment to arrive and prep the landing site. This landing crew will be the first to extract resources from the lunar surface, and thanks to a newly added mission objective, they will use a small refinery sent aboard the cargo lander to produce fuel to help return to orbit. If the procedure goes well it will help lessen Marius's reliance on supply ships, and allow Aurelian to be refueled cheaper and faster.
  7. I decided to give your shuttle a test flight tonight, here's a photo that was taken during the underwing inspection with the Canadarm: I think I'd like to try to reverse-engineer parts of your shuttle to build one of my own. I've never finished a working STS, but this example has a lot of techniques that have really piqued my interest and given me ideas...
  8. I’m really interested in that Shuttle, can you go over any special techniques you used to build it?
  9. If I could state my own humble opinion... My suggestion would be to finish the shuttle tower first, then work on a launch tower for use with smaller rockets, namely something like the Titan II service tower and erector, or the gantries used in Atlas and Redstone launches.
  10. Indeed. Of all the rooms I could have gotten with a magnificent view of the parking lot, I got the one with a window full of leaves...
  11. Thanks to all you guys for your support, I'm posting this from my new residence in Huntsville, with the US Space and Rocket Center's Saturn V right outside my window (or it would be if there weren't a tree blocking the view).
  12. Disclaimer: I believe this to be the best place to post this thread, however, if a moderator believes that another forum would better suit the topic of this post, I ask that they move thks thread to where it is more appropriate, thank you. I first picked up Kerbal Space Program sometime in 2013, not long after the 0.20 update came out. I still remember the old white-walled VAB, from which my first rockets rolled out, most of them asparaguslike monstrosities which needed to be lashed together with dozens of struts in order to hold together. Since then, I have played the game quite frequently, and improved my skills to a point where replicating some of mankind’s greatest space flights, such as the Apollo program, feels entirely natural and routine. I have been active on these forums for the last few years, and many people have praised my creations here, from my World War II submarines to my lunar space station. While in many ways I have learned to harness and mold the game and the laws of physics which are represented within it to do my bidding, Kerbal Space Program itself has also molded and shaped me as well, and the impact it has left on my life is quite significant. When I bought this game I was in eight grade, still practically a child, with no real idea what I wanted to do with my life. Sometimes I thought I would study history, a longtime passion of mine. At other times I told myself I would join the army and become a helicopter pilot, like my father before me. Other times still, I thought I would try and become a writer, although my attention span soon proved to be much too short to produce any kind of significant written works. However, after a year or two of playing this game, experiencing the thrill of designing my own spacecraft, and then actually launching them to the stars, I knew for certain exactly what I wanted to do with my life. Spaceflight has been an interest of mine for a very long time, ever since I saw the news coverage of the twin Mars Exploration Rovers bouncing their way to the surface of Mars, or the occasional footage of a space shuttle blasting it’s way to orbit, but for most of my life it had simply been yet another interest of mine, something that I enjoyed, yet did not have enough knowledge about to fully appreciate. Really, it was just a candle, burning alongside many others, neither brighter nor dimmer than any other one. However, as I played the game more and more, I realized I wanted to learn even more about the world of spaceflight. I wanted to learn how NASA did things, so that maybe I could replicate their achievements in the game. After that, I wanted to learn about the science behind spaceflight itself, so that maybe I could start building more original designs, rather than imitations of real spacecraft. Kerbal Space Program poured gallons of rocket fuel on that candle that was my curiosity for spaceflight and helped it grow into a burning passion for the exploration of the vast world beyond our own thin atmosphere. Due to the game’s impact, I am preparing to devote my entire life to the study and exploration of space. Tomorrow, I leave home to study aerospace engineering at the University of Alabama in Huntsville. I am fully convinced that this is the right choice for me, and I believe that without the hands-on exposure to space that Kerbal Space Program has offered me, I doubt I would have ever reached this conclusion. I am looking forward to my studies with great anticipation, and am also exhilarated at the fact that I will be living and learning just a few short miles from where the mighty Saturn V moon rocket was designed, at the Marshall Space Flight Center in Huntsville, Alabama. Having said that, I would like to express my deepest gratitude to the Kerbal Space Program developers, as well as to Squad, it’s parent company, and especially to Mr Felipe Falanghe (@HarvesteR), the original creator of this remarkable game. It is because of you all that I am about to take this next step. The inspiration you have given me will stay with me forever, and I hope that I will continue to enjoy Kerbal Space Program for many more years. When it comes to the internet, I am typically a very private person. However, would like to share a photograph of myself at the Kennedy Space Center Visitor’s Complex. I recently took this trip as a final vacation before leaving for school, and while there I suddenly realized that the reason I was there in the first place was due to one game about a group of little green creatures with a collection of rocket parts and a launch pad. With sincere gratefulness, -Trevor P. , Aspiring Aerospace Engineer
  13. I wish you luck with this one; the FSS looks so much more complicated than the fairly straightforward Apollo/Saturn launch tower.
  14. EVA training for Surface Expedition 3 is underway. This mission will be the first to land at a resource deposit and will bring with it special equipment for sampling ore from the surface. No high-intensity mining will be attempted on this mission, but a small amount of ore will be extracted for testing. In order to safe space, this mission will not carry the bulky dish antenna used by SE-2, instead this mission will use Aurelian's main antenna to transmit to Kerbin, while the SEP will only transmit data when Marius passes overhead, eliminating the need for a dedicated long-distance antenna stand. This mission also has a new electrical system. The new stand features bigger solar panels which can track the sun, as well as two radiator panels, to help shed away the heat produced by the mining equipment. The mission will also carry a full suite of SEP instruments, which will be linked into the same central station as the solar stand and mining rig. Many cables are crosses over one another in this training operation, but on the Mun, the instruments will be more spread out. A hose was also connected to the Aurelian Training Mockup, to simulate a potential plan to supply Aurelian with power from the electrical station during its surface stay. Such a setup would help improve conditions during the lunar night when solar power is unusable. However, in order to achieve this, the power station will have to be modified yet again with RTGs in order to provide a constant, efficient power supply throughout all conditions. The training test was promptly terminated once it was realized that due to a miscommunication the crew had proceeded so far into the test that they had begun drilling holes in the side of the launch pad.
  15. Actually, I was wondering if the command seat's mass value in the SPH factors in the weight of a Kerbal sitting in it, I guess now I know...
  16. Business as usual continues with lunar orbital operations, the first Scipio-FT has arrived at the station. The fuel FT-1 delivered will soon be used to fuel up Aurelian 2 for its second journey to the lunar surface, once its next crew arrives. FT-1's launch was perfectly standard, using a typical Princeps 2, and the flight to the Mun was uneventful. There was an issue with the spacecraft's electrical system, causing it to lose power in the critical moments before docking, however the crew aboard the station was able to achieve a negligible relative velocity before the power loss, and so the spacecraft was able to stay in position long enough for the problem to be worked. Docking proceeded as normal, with the spacecraft now berthed to the aft node of the Marius Core Module. Meanwhile, back on Kerbin, to help add some more variety to this save, I've begun working on a sort of concept demonstrator to help me determine the feasibility of constructing a glider for use on Duna one day. It seats a single kerbal, and is extremely lightweight. An actual interplanetary aircraft will probably be powered by a liquid-fueled engine, or possibly monopropellant system, but this early test rig only uses two separatron rockets to give it a short boost into the air for about thirty seconds to one minute of flight time. The spherical fuel tank underneath the wing is intended only for ballast, although in the future it may be called upon to power the aircraft itself. The glider is certainly airworthy, although without any kind of power plant, it is extremely slow, and really lacks sufficient lift to serve as a dedicated glider. Future test models will possibly be towed into the air with another aircraft, or simply given engines of their own, in order to test long duration flight at various altitudes. Currently, the aircraft is slightly nose-heavy, but it flew a surprisingly long distance, considering how weak its takeoff boost actually was. I have no idea what's going on with the wheels sticking out of the top of their fairings, but I guess it's something with the game's suspension model... This design still has one problems to work out, namely issues regarding landing. Many other things will have to change before this aircraft will have evolved enough to be worthy of an interplanetary flight, but this is a start nonetheless.
  17. After much procrastination, excuse hunting, and genuine fear of confronting this 600+ part menace, the Marius airlock is now in place. This newest addition to the station will make spacewalks much easier, and allow spacewalking crewmembers much more capability in servicing the station's exterior. Just like most other lunar-bound payloads, the airlock module is launched aboard a typical Princeps 2 rocket, the medium-heavy workhorse of the booster fleet. The Scipio Upper Stage is used to propel the payload beyond LKO and insert it into Lunar orbit. Once in Lunar orbit, the Scipio Delivery Module acquires Marius on its rendezvous radar and begins procedures for closing with it. The Delivery Module is simply a modified Scipio Service Module, with the heatshield adapter removed, and the rendezvous radar relocated to the side paneling. Close approach and docking procedures are taken over by the station crew, using modern television guidance systems. Docking was a little hairy, especially when I realized that the delivery module's solar panels might collide with the Marius Main Solar Array, however, no such thing happened and the airlock was safely hard-docked. Once safely connected to the station and wired into the power, water, and electricity systems, the airlock was pressurized and the hatch was opened. Shortly after this the delivery module was jettisoned and commanded to separate from the station. It was then set to deorbit itself and impact the far side of the Mun, to avoid a future collision with the station. The Marius Airlock Module will finally allow EVAs to be conducted from a dedicated platform, rather than the Scipio Orbital Module, and will provide storage racks, EVA refueling canisters, and a safety tether to ensure safe, easy, and efficient spacewalks. It also has the same integrated radiator systems present on most other station modules, reducing the need for large and flimsy deployable radiators. With the docking successfully accomplished, the crew now begins an inaugural spacewalk, to test the airlock's new systems and to clean up the station's exterior to help streamline the performance of my computer. Four handholds are clustered around the airlock's end to allow easy access to the two storage racks mounted around the egress chamber, as well as a safety tether. The main goal of this EVA is to remove several items that have become either redundant or obstructive with the airlock's arrival. This includes the tether and storage rack on Aurelian 2's docking node. Both items are now unnecessary due to the nearby storage and tether provided by the airlock. These parts will be placed in a container until the next opportunity arises to dispose of them. Several short-range antennas are also removed from the Core Module and Node 1. These are also redundant, as the station can easily send relays to the two Cato satellites. Both antennas are also obstructive, providing very little clearance between the airlock and the station's main "spine". This kind of decluttering EVA will take place periodically, as the station grows larger and my framerate drops. Marius is already at 625 parts, and I haven't even come close to finishing it according to my plans. The next flight bound for Marius will likely be Scipio-FT 1, with its payload of fuel for Aurelian, and after that, the Expedition 3 crew, which will make the second landing, and take over station operations from Expedition 2 afterward.
  18. Despite being absent from this thread for something like twenty days, I actually have very little to report. The summer keeps winding away, and with it, the time I have left before I leave for college, so I've had to spend most of my days packing up for the move. Fortunately, I was able to get back to this a little bit more tonight. The bad news is that all I was able to finish was two prototype craft in the VAB. First, another variant of Scipio. With the beginning of regular surface excursions with Aurelian II comes a drastically increased demand for fuel in Lunar orbit. Say what you will about that beautiful spacecraft, it's an absolute gas-guzzler. Unfortunately, Scipio-ST's capability to carry fuel is much lower than I had originally thought, and as it turns out, it can barely ship enough fuel to lunar orbit to fill the lander's tanks, let alone provide Marius itself with fuel for orbital corrections. Once I begin mining on the surface, I should have an easier time of it, but until then I need a bigger tanker that can provide a large amount of fuel in a single flight. Scipio-FT (Fuel Tanker) is basically a stripped down version of the old ST ship. The pressurized cargo module has been removed, and with it the ability to carry KIS containers, but in exchange, the propellant storage tanks have been made much bigger. Furthermore, there is only a single (yet very large) fuel tank within the propellant module, which will make manual refueling much faster and simpler. The FT will likely end up replacing the ST, and any parts I need to be shipped to the Mun can be carried on board a crewed ship instead. Second, the first of several logistics vessels intended for constructing or servicing the surface base, once its location has been chosen. This cargo rig can land up to four KIS containers on the Lunar surface In addition to miscellaneous cargo, this rig will likely deliver smaller base components, such as the basic structures of the drilling rig and refinery. Another cargo rig will deliver additional fittings such as radiators, solar panels, KAS connectors, the drills themselves, etc. The surface crew will then install the boxed up components on the equipment structure, to form a complete and fully functional drilling rig. I'm still working out the details, but I think this way will pose the smallest challenge while being versatile enough to adapt to any changing circumstances. These cargo rigs are intended to be disposable, and once their payload is delivered to the surface, they will again lift off and crash themselves on the far side of the Mun to remove clutter. Anyway, I'm really not looking forward to refueling Aurelian for its second sortie because of the lag I experience whenever loading Marius, that's why I've been doing smaller things like the Sarnus probe and these other projects. Eventually, however, I'll have to get around to it...
  19. But... doesn't the term "Base jumping" imply that the jump is performed from the ground or from a fixed structure?
  20. I've added the Outer Planets Mod to my game, and my Sarnus transfer window is open, so I'm sending a probe to the outer planets and possibly even interstellar space. The high DeltaV requirements of the mission require yet another new launch vehicle. This one is an improved version of the Auxiliary booster, with a more powerful first stage engine, larger SRBs, a much larger second stage, and a new third stage. I swear to god this isn't (exactly) a copy of the Atlas V, it just turned out looking like this... This new vehicle has been christened Auxiliary II, and will also be used for unmanned launches, mostly for heavier probes and interplanetary spacecraft. It can also be used with variable numbers of SRBs, depending on the payload, and will likely serve as a workhorse of the fleet. The third stage used on this mission is also new and served extremely well during the burn to escape velocity. It may be adapted for future manned flights, pending future testing. Once the spacecraft is placed on its course for Sarnus, its three equipment booms are deployed. Each one is connected to the spacecraft by a docking port and is rotated out of the way during launch. Once safe to do so, the arms are decoupled and remotely maneuvered to reconnect to the probe bus, and control is provided by a probe core and sets of thrusters on each arm. The arm at the top of this photo holds the probes two RTGs, which will be used for power in the distant reaches of the Solar System, where photovoltaic power is infeasible due to the distance from the sun. The bottom right arm features the magnetometer, which will be used to measure the magnetic fields of Sarnus and any other bodies encountered. The bottom left arm features various other scientific instruments such as thermometers, cameras, gravitometers, etc. This probe is named Sagittarius, the Latin word for 'Archer'. Sagittarii auxiliary units appeared in the Roman military sometime in the early empire. After encountering eastern peoples such as the Parthians, the Romans began using mounted archers, which were much more adept at harassing the enemy from a distance than foot archers were. By the time of the late empire both foot and mounted sagittarii were much more prolific in the army. The Eastern Roman Empire continued to use mounted archers well past the fall of the Western Roman Empire and into the Middle Ages, due to their proximity to eastern empires such as the Sassanids and later the Muslims, who used cavalry to great effect on the open desert plains of the Middle East. After fully deploying its equipment, Sagittarius turns to point its high-gain antenna towards Kerbin. This will be its main orientation for much of the mission. The probe has a long way to go before its encounter with Sarnus, but I'll check up on it every now and then for midcourse corrections and such. Currently, its voyage to Sarnus is expected to last 2 years and 300 days. Following its flyby with Sarnus I will attempt to get a gravity assist to Urlum (Uranus's analog in OPM), but failing that I will attempt to slingshot the spacecraft directly into interstellar space. Before people chastise me, I know it looks like Voyager. I wanted it to look like Voyager, and its mission is intended to closely mirror Voyager's, but nevertheless, I did my best to instill some spirit of originality in it.
  21. Would that mean four satellites all with their apoapsis above the north pole, or two with their apoapsis at the north pole and two at the south?
