  1. My Circumnavigation Mission Kerbin - Complete Minimus - Complete! Mun - COMPLETE!! Duna - just started :V [BACK ON new prototype reaches sustained speeds over 80m/s!] -------- This... is it. The Enerstar E3 landjet Propelled primarily by 2-3 jet engines with 8 electric drive wheels to assist in launch speed. It has two miners ore bins and an onboard fuel converter. Enough passenger space for two in addition to the driver. You can even get out of it. -------- Early on I decided to test the capabilities which was probably a mistake as it required a lot of saving and yelling. So we went up through the mountains northwest of KSC And they did survive apparently. Next stop! The north pole! The north pole! It was at this point I came to a realization. I can't always rely on ore deposits. Or that was the thought (turns out you can) I also realized the ship needed some extra capabilities, bracing, and safety features. But I can't ruin their glory by sending a 2nd team, and I don't wanna drive all that way a 2nd time. What to do? Obviously the most logical solution is to spend millions upon millions of dollars in failed projects to ship a NEW land-train to the next continent. I tried LOTS of methods, one including an ICBM to launch the train, but usually this resulted in the aeroshield being full of train-soup and spinning out of control. A small child picked up a model of the train and flew it around the office, after yelling a lot, we decided "no! this is actually the best idea, I'm going to take the idea and give the child no credit" Thus the Enerstar E4 Carrier was born This was totally necessary because the E4 model is much better braced and capable of making the rigorous journey intact thanks to its increased bracing, batteries, and safety* features. The 4th generation also has the ability to dock with supply drops in order to get it out of areas with little to no ores. So far we haven't really found any areas that you would get stranded in, but we did spend tons of money making sure we wouldn't get stuck in one. More to come later as Crew-E3 makes their way south toward Sandoland to meed up with Bill delivering the E4 Ore-pod drop Passing the river south toward Enerstar-E4 FINALLY Bill hands off the Enerstar-E4 to the world-trip crew So that's the progress thus far. The next plan is to visit the pyramids.
  2. Back at it again for those who saw the previous trip. I hadn't posted much on my other one but I've completed Duna, Mun, Minmus and Kerbin once But now. I've produced a new version of the Enerstar the model S Why? Because I felt I missed out on a lot of the planet my last time around. Whole continents i never explored, mountaintops un-flagged. That's why Enerstar S has 6 engines. In stress tests the engines were powerful enough to nearly lift the whole thing straight up when at full rev + boost I haven't gotten it to a "max speed" because I tend to run out of room by the time I reach 190m/s.. but the 'safe' cruising speed is more like 30-50m/s faster than my last one due to being wider and less prone to flip. Model S has 289 parts total 6 rear engines with afterburner mode for steep climbs 2 reverse engines (which are also.. reversible..) 1 cockpit, 2 crew modules, 2 large ore tanks, 2 ore processors sensors, heat, gravity, pressure, air sensors, ore scanners, and 1 top area scanner Dry weight no fuel 50 tons Full mass (ore and fuel), 100 tons https://imgur.com/a/QOzMfKv gallery location Front view Back And from the top before my first watercrossing into Sandoland Mountain climbing Top/side for a nice look at it And lastly a topdown comparison of my oldest model when I met up with where I left it More to come as I get going
  3. This is something I wanted to do for a long time now: Drive all around Kerbin in a stock buggy. To prepare this rally I've used the Kerbal Konstructs mod and placed 7 bridges needed to complete the route. For this challenge I will use a hybrid buggy, so refueling will become a thing. Like in my Pole2Pole challenge I will allow a new buggy to be flown in as a replacement when I break down. The buggy:
  4. So......after chatting with @Triop on this subject, I have decided to throw my hat into the preverbal ring and drive around Kerbin within 80 days. How hard could it be? Driving is easy.....boring but easy, right? WRONG!! Kerbin is one of the toughest places to drive a rover, truck, dune buggy, race car, etc. Whatever you drive, you're driving on a planet that has some of the most varied, roughest and unforgiving terrain in the KSP universe. Add it's rather strong gravity, and you have a challenge. Some other planets have rough terrain, but most of them have lower gravity (with exceptions of course). So you're rover/buggy/truck has to be well built, tough as nails, your driving must be razor sharp, and you have to pay attention the entire time you're driving. Your speed must be well regulated because wheel blowouts are the least of your problems (they can be fixed). Go too fast, don't pay attention to what's coming up ahead of you and BLAMO!! you're careening off a cliff, going end over end and most likely killing your intrepid but less than experienced pilot and engineer if you managed to drag one with you, probably kicking and screaming. So...... DAY ONE Early morning. The MEGA Truck is finally ready. Our most experienced pilot and navigator extreme GDJ Kerman (yeah for real) is ready to take the wheel with a few somewhat willing crew. Kerbal Foundries was generous enough to supply a high powered APU unit for the truck's power source which a claimed 17 units of electrical charging per second and a fuel consumption of no more than 0.03 units per second. With additional fuel (1250-odd units) the frame of the truck was creaking with it's total weight of 20.4 tonnes. This was no ordinary 2019 Kerbal Star truck. This was a custom made Tri-Drive Tandem steer unit with a extended cab for two other occupants. Nearly 10 metres long, almost 2 metres wide, this was a beast of a truck with the power of the Kraken. After firing up the APU, a quick test was done and a plume of exhaust shot up in the air nearly as high as the VAB. Everybody smiled. Yeah baby! After KSC gave everybody in the truck their best wishes for success, the intrepid 4 nutcases were off and running. The truck spun around from the runway, sprinted north at a pace that was nearly dangerous on level ground. GDJ Kerman looked at the speedometer: 41 metres per second. After leaving the level grounds surrounding KSC the most experienced pilot in KSC history remembered some advise from his mentor and former teacher Gene Kerman: "Less is more. Don't push your luck and risk everything. This is not a race. Nobody has done this before, and the only other one crazy enough to do it @Triop is still out there. Take your time. Besides, the truck is brand new and bloody expensive." Time to slow things down. 30 to 35 m/s would be sufficient. The plan was to travel to Kerman Lake on the first day. Kerman Lake was roughly north east and had a small airport for smaller regional aircraft. Most of the terrain was not really rough until one got to within 20 km of Kerman Lake, then it was a lot more challenging. Bill Kerman was the chief engineer, Jebediah Kerman was backup pilot, and a newbie Scientist that was still wet behind her ears was in charge of ......the science stuff. For the most part, the day went off without a hitch. A few times the truck was airborne for a few seconds, but the robust suspension handled the abuse like a dream. Bill did some adjusting to the steering parameters as the drive progressed and made the high speed handling a little less....hazardous. The APU sipped at the LF, keeping all 1600 units of battery power charged at 99.5% and only went full blast when driving up hills. The brakes were equally impressive. Kerbal Star equipped the truck with 10 Krembo disc brakes and all together was able to stop the 20 tonne monster to a halt within 150 metres, give or take a bit. After a few hours and in dwindling daylight the crew arrived at Kerman Lake, tired but not too badly shaken (thank you air-ride seats!) and decided to plan out the next days trip in a nice hotel. SUMMARY FOR DAY ONE
  5. One of the reasons I created the Heisenberg mod and the recent Buffalo Wings update was so that I could go explore Kerbin. I haven't done that before, and it seemed like a good thing to do. The idea originated from watching EJ-SA's "Kerbin Exploration Initiative" streams and from the Elcano Aviation Challenge. I had the notion of making an epic story out of the mission, with lots of dialogue and plot twists, but after months of modding, I'm still not finished with my mods, and time constraints mean that I wouldn't be able to do my story justice. So rather than let my hard work go to waste, I opted for a more traditional mission report with news reports sprinkled in that's relatively light on story. I can update it when I have the time, but at least I get to play KSP again instead of just modding it.

  6. This thread is about my rover trip around Jool's moon Vall. This is meant to be an Elcano/Elkano attempt where I carry out a polar circumnavigation of Vall. Here I intend to provide enough screenshots to document that I actually do the complete circumnavigation and to show the beauty of Vall scenery. Also I allow my self to use f5/f9 as much as is neede. Why to circumnavigate a celestial body by land in KSP? I will have to admit that a land circumnavigation of a celestial body in KSP is very lengthy and tedious process. Nevertheless I have wanted to do so ever since I heard that the Elcano challenge exists. I have former experience from a lengthy rover science gathering mission on Mun. Despite hours of tedious driving around the gray landscape of Mun, I did find the mission quite fulfilling and rewarding. Partly just because it took a long time to get anywhere. I expect this mission to be similarly rewarding experience. Why Vall? Previously my goal was to perform a similar circumnavigation of Eve, since is Eve my favourite planet in the stock Kerbol system. My plan to perform this circumnavigation in reasonably short time and fun way, was to use the Rovemax XL3 wheels, and exploit the fact that they can accelerate the rover to extremely high velocity if you tap the keys "a" and "d" while pressing "w". Unfortunately the challenge maintainer of the Elkano challenge was adamant, that this is cheating and not allowed. After trying out a rover that obeys the rules on Eve I felt that it was frustratingly slow and couldn't climb the hills and mountains of Eve. So the circumnavigation would take a very long time and be more frustrating since I couldn't scale hills and mountains. Vall was the next best option. A lot smaller, but sill reasonably beautiful celestial body, whit low gravity to make rover faster and better at climbing mountains. Relevant mods Voyage to Vall This is the rocket at launchpad. It devotedly follows the design principle "There is no such a thing as too much deltaV!". It has several thousands extra m/s of DeltaV to make sure that Vall is actually reached without shadow of a doubt. This was my first ever manned flyby or orbit of Jool. :-) Successful landing! The land voyage may now begin. The blue flickering is from the Sci-fi visual enchancement mod. I'll soon make a new post once there is progression to show. Thank you for your time!
  7. Some of you might remember that in my last AAR, I promised to do a circumnavigation of Minmus in 6.4x scaleup. Well, that AAR died, and the save is lost, but I've been playing some more KSP again lately, and I've finally reached a point in my current career game where I can attempt a Minmus circumnavigation. Consider this my very belated entry into the Elcano challenge. THE MODS Here's the entirety of my modlist, as pulled from CKAN: I'm also running Simga Dimensions (0.9.3), with the following configuration settings (applied through a mod manager config): @SigmaDimensions { // Base Settings @Resize = 6.4 @Rescale = 6.4 @Atmosphere = 1.285 @dayLengthMultiplier = 1 // Advanced Settings @landscape = 0.25 @geeASLmultiplier = 1 @resizeScatter = 1 @resizeBuildings = 0 @CustomSoISize = 0 @CustomRingSize = 0 @atmoASL = 1 @tempASL = 1 @atmoTopLayer = 1 @atmoVisualEffect = 1 @scanAltitude = 1 } Not all of these mods were used in the construction of the rover, but I'll do my best to point out mod parts when they show up. THE PLAN The rover I intend to use for my circumnavigation attempt is called the Cricket. It has 8 ruggedized wheels, space for two Kerbals, a bunch of science instruments, and is powered by a fission reactor from Near Future. Top speed on level ground is over 55 m/s. Due to its size and shape, I've packed the rover into a DIY Kit from Ground Construction, and will be assembling it in situ at my Minmus base. Once assembled, I'll take two of the base crew on a three hour cruise circumnavigation attempt of Minmus, gathering science along the way. The exact route has not yet been determined, although I intend to visit at least one of the anomalies I can see on my ScanSat maps, as well as the site of my first kerbal landing in this career save. I'll post a waypoint map of the route before driving begins. THE LAUNCH I launched the Cricket (or, rather, the kit which will be used to assemble it) atop a Sartre CRD. Capable of placing 10 tons into Minmus orbit, the Sartre (and its little brother, the Sartre Jr.) is the workhorse of my space program. The CRD variant is a recent design overhaul that standardized the common components of the Sartre and Sartre Jr., and added recovery systems to the boosters and core. (Every Sartre launch costs me about 220,000 funds, plus payload. Of that cost, almost 60% is just the four boosters, so recovering them is a high priority.) Images of the launch and transfer burn below. (Imgur album embeds are apparently broken again, so have this direct link.) (Single image embeds do appear to work, so have this image of the launch as compensation. Full album in the link above.) Up next: Arrival at Minmus, landing, and assembly.
  8. HRO shuttles, originally designed for some advanced levels of STS challenge, now join together for even more daring mission than before Launch sequence First is HRO-M03 with all the deployable vehicles. Including the Elcanoplan 2 strapped on its back Barely enough thrust for takeoff (and that's with payloads having the tanks practically dry). I even activated the main engine of the Elcanoplan, but that didn't seem to make much difference either. Those boosters barely miss the tail wings (just don't forget to set SAS to prograde) Also waited a bit after the tank ran dry before separating it - to wait for the ship to get a bit more balanced (orbiter's tanks are set to drain from the tail first) 55 km? Eh, this isn't Laythe yet! Also forgot to ignite OMS OMS + upper pair of main engines = the best balanced solution with this payload. One ship in orbit OK, now to the second launch... What the Kraken?!! OK, After a tweak to the clamps... let's pretend that didn't happen HRO-M takes off a bit easier, despite having full payload bay as well Looks like we launched a bit too early Well, raise the apoapsis a bit higher and let's meet in one orbit Let's align... and wait for some sunlight Despite the size, HRO is quite good at docking. If you don't rush. (Hey, it's called Heavy Recovery Orbiter - what else could you expect?) This position will provide the best balancing And in couple passes we get the transfer to... somewhere green But this is... Anyway, let's get into polar orbit. By the way, HRO-M also has the scanner antenna in the bay Going down This modification of HRO-M has got some landing upgrades from the latest version of HRO-M03 And a full mining rig in the bay Minmus means "mine me", doesn't it? And a few days later... And in the meantime HROM-03 changed to equatorial orbit - so here's the direct intercept with it There's enough to fully fill all LFO and ore tanks of the craft in orbit So let's make another run down - this time at the equator And after refuel... Who needs atmosphere for horizontal takeoff? And back together - with plenty of fuel Transfer And over 300 days later... (yeah, completely missed the window) What's the best way for Minmus-Jool transfer? Oberth effect! Say goodbye to Kerbin! And a couple years later... Let's just capture into Laythe-Pol transfer orbit What a view! And then, since there seems to be enough fuel to reach the destinations independently, let's separate the ships Oh, hey there! Has anybody checked for running into Vall? Now to pass by Tylo - barely missing its SOI (turned to get better solution than with slingshots) and we are getting to the destination Let's capture with rocket engines, and then release the mapsat - it will change plane at apoapsis Now, to lower the orbit... the shuttle way Strangely enough, the moment you get in, it feels about as much (if not more) drag as on the same altitude on Kerbin. Just don't forget to stabilize the orbit Low Laythe orbit achieved! Next phase - going down there
  9. As the title says, this mission is a circunnavigation of Mun for the Elcano Challenge: However, for my crew it doesn't mean going in a straight line from A to ... well, A again the long way. The plan is to collect science from all the biomes, mark anomalies and complete as many surface missions as possible (career mode). The rover is quite light under 10T, so i simply attached it as cargo to the nose of a ship used to carry fuel from the Minmus refineries to LKO and equipment from LKO to Minmus and Mun. This is a new design i'm using to replace my old transports, it's pretty much the same, but with big docking ports for cargo stability, better solar panels and upgraded comm gear. It also carries a little bot to move cargo to stations and to move the big heat shield under the ship to the rear docking port, to speed up the aerobreaks when returning to Kerbin. This is not the original launch, i forgot to record it so i recorded it again and left a second rover in a Mun equatorial orbit in case it was needed. Jebediah Kerman, director of operations and explosions of the KSP, and badass in general, personally selected Elixie and Jean as the crew, based on very strict criteria. (i.e. they were aboard a ship in LMO when the rover arrived and had the right professions ) DAY 1: This is Mun base Alpha, a simple base with a few oudated vehicles, and starting point of the journey. There used to be ore just below the base, but suddenly one day it was gone. (game update to 1.2.2) The scientists keep studying the sudden dissapear, but orbital surveys still show big ore deposits in the area, and to locate them is going to be the first mission. Flag time for Elixie: And there they go! Finding ore was actually very easy, and as soon as they approached the nearby canyon, less that 1 km away from the base, the scanning module began beeping. And the science-o-meter also began beeping for the new biome. This crater was a nice opportunity to collect science from the lowlands and midland craters... ...and to mark the first anomally, a monolith. What strange species planted this structure here and why? Do they have tasty snacks to share??? Next, the flat area north of Base Alpha was perfect to test the rover speed. 45 m/s seems about the top (safe) speed. Faster than that and the "small jumps" are not so small, and the "landing" not so smooth. Anyway, the travel to Farside Basin was quick. Keeping the north heading, a pair of surface experiments to complete a contract: Surprise! And this is the reason why the rover has two thrusters below, because of the ninja craters hiding behind hills! The ability to orbit / deorbit is just a side effect (but very welcome). Don't try this at home! Jeb will be proud of these two kerbonauts... Unfortunately, the next barrel roll didn't go so well, and this is the sorry state the rover had after. Energy generation was all but gone, with only the small solar panel on the top still remaining. The docking port on top was gone too, and the RCS tank connecting to the cockpit didn't look good either. Also, the direction was damaged and the rover had a tendency to turn to the right. However, the science was intact and the kerbonauts alive. With 1000 EC the rover was able to reach the other side of this big hole, the first sign we are near the north pole. But after that last effort the batteries were empty. By the way, this biome is the highlands, so more science to carry! So, time to deorbit that second rover. The burn to send it near the north pole required a lot of fuel, but that was not a problem for the transport: The rover handled the landing without problems too: A few km later, the kerbonauts were rescued, and passed all the science and the remaining RCS to the second rover. All the RCS was stored in the side tanks, and it really helped with the barrel rolls. The CoM is a lot lower and the rover is more stable. Since both rovers were docked, the first one was left with full batteries, and i think the direction damage fixed itself with the change of scene (the RCS tank is again in line with the others), so trying to bring it back to Base Alpha is a possibility. Next biome: Highland Craters. The long shadows near the poles can be a problem for an electric vehicle, but 3000 EC should be more than enough to keep going. The sun is still high in the sky when we reach the north pole... but it won't last long. And the terrain is becoming more irregular, increasing the energy requeriments and decreasing the speed. It's not a problem yet, but up north it's full of peaks and valleys, not the best place to drive at 40 m/s. Home over the horizon! The marker on the map is the first patch of polar lowlands according to the orbital survey, so that's where we are heading. The map data appears not to match the terrain, so we picked a deep hole and went down to collect some tasty science... but turned out this is not polar lowlands. After another try in the same area, the only choice appears to be to keep moving north and aim for the deepest rift. This one should do the trick: EC is becoming a concern. The mix of deep dark valleys and high peaks where the batteries can be recharged are making this part of the journey quite slow. Not to mention the constant danger of driving in the shadows and falling into one of the valleys. The next rover will include moar lights for this type of terrains. Then, in a routine climb for energy Jean checked the biome... yep... polar "low"lands. I guess the SCANsat data was fine, but it doesn't make much sense to have the lowlands on top of a mountain. In the words of the on board computer: Not computable. The crew was eager to leave this polar nightmare of mountains, valleys and darkness, and there was still some sunlight available in the mountains, so they managed to reach the border of the polar crater and finished the first part of the mission. Biomes visited so far: Midlands, Canyons, Lowlands, Midlands craters, Farside Basin, Highlands, Highlands craters, Poles and Polar Lowlands. Anomallies discovered: 1 monolith. Contracts completed: 1. Rovers lost: 1 (still semi-functional).
  10. EDIT: I've put this on hold until I can play the game without CTDs. TL;DR: Elcano attempt gone awry. Two budding engineers steal Jeb and Bills' Elcano Rover and go for a spin. Scroll down to get straight to the comic. Longer, yet still readable: I was making grand plans (and many design iterations) for a Kerbin Elcano Challenge attempt. Didn't like the fact that my very capable speedboat had to forego rover wheels for airplane landing gear to be amphibious AND fast. Frustration is best left on the back burner for a moment, and so I cleared my head by making a couple cool jeeps and land rovers and pickups. One of these turned out to be great fun in the hills and mountains west of KSC. Only problem was it had no means to do water crossings. I considered detachable pontoons and a polar route so I could knock out the water part relatively early, then get on with it. Then I said screw it. I'm gonna break the rules. I'm more interested in telling a story than getting the badge. I'll go ahead with the truck. So, within the story, the idea is that 2 yokels from a shared rural childhood make their way to marginally successfully careers doing menial engineer tasks around KSC. Gus is a little more diligent, and makes Lt. Engineer, rising to help with minor design implementations of the Elcano rover. Thomp does just enough to get by, so him and his pal Gus can share their adventures, and usually spends his day at various custodial duties - the most prestigious being cleaning out engine bells at the test stand. Anyways, their story picks up with them enjoying a few "snacks" after work. Hope you enjoy! CHAPTER 1 Already working on chapter 2! Thanks for taking a look. *HICCUP*
  11. Commander's log day 1: Well, I don't know how to write in a journal. I guess I'll introduce myself. I am Jedediah Kerman, the commander for the amphibious Kerbin circumnavigator the "Elcano IV." It is a hybrid vehicle that is capable of long distance travel across Kerbin. Our ship is a beauty. It has a crew of 6, a movie theater, a kitchen, ore drills and converter, cozy accommodations, and plenty of snacks. I am proud to call this ship my home for sometime. Elcano, here we come.
  12. I decided to try an Eve Elcano because I usually avoid Eve, besides putting a simple science probe on the surface. I am doing this in a career save I began about 2 weeks ago and I am running ScanSat and Kerbal Engineer as the only mods. Mission Profile: The interplanetary vessel "EVE" will launch from Kerbin and make a polar orbit around Eve. A Scan/Comms relay sat will be deployed into approx. 499x499km orbit (Sub optimal orbit for both scanners on-board however maximising monoprop for final orbit after scanning is complete). The "Eve" will move to approx. 150x150km orbit to deploy the "victim rover". The "Victim Rover" will de-orbit itself as close to the north pole as possible with Neldo Kerman and begin the Elcano. The Eve will attempt a polar transfer to Gilly in order to deploy a second Scan/Coms bird and then return to Kerbin for refuelling and docking a return module for Neldon (if I can be bothered). Launch and Delivery The Elcano Begins
  13. Hello guys! This is the mission report of my trip around Kerbin. I am going to drive as much of the trip as I can, but I will have to cross the sea in a few places, and also some rivers along the way. I am doing it because i haven't really seen anything of this magnificent planet further away from the KSC, than a 100 Km. K.R.A.C.I.I [krey-zee] K.R.A.C.I.I is the rover I am going to use. It is an acronym for Kerbal Racing-car with Amphibious CapabIlIties. It has a cruise speed of about 40 m/s on land, and a bit below 20 m/s in water. It brings enough solar panels to deliver power all day, but it can not drive in the night. The front spoilers pushes it down so it can drive fast over edges without destroying its tail. The Map I have planned a route on a polar path. (The yellow line). It will take me trough mountains, across rivers and by the beaches. If there should come a point i can not cross, I have emergency routes. (The orange lines). So if the mountains are to rough, I will have to drive another way around. The grey line is the route I will take by plane, and the yellow dot represent my desired landing spot. Progress so far This map will be updated and more flags will be added as Jeb move on. The newest pink flag, represent Jeb's position. Please tell me what you think about it, i would love to hear your opinions!
  14. The past weeks have seen a big spike of Elcano attempts. Many of them have a beautiful and witty narrative, something that's really not my strong suit. So why post yet another one? Simply because this particular circumnavigation is a long standing project of mine, and because I'd like to share my passion. Since Imgur and the KSP forums don't get along at the moment, I'll post my images in spoilers and add a link here and there to keep loading times reasonable. Nine months ago, I circumnavigated Kerbin by boat. It was my first attempt at the Elcano Callenge, and the views of Kerbin that this journey offered me got me hooked. But also from an engineering point of view, I learned a lot about hydrofoils, so I started to make plans about a circumnavigation of Laythe. Of course, it never ocurred to me that it would take this long. One of the most important lessons from my first attempt is, that having too many lifting is a surefire way to have your craft flipping when low on fuel. I suspected that my pontoons were part of the problem, so my subsequent designs tried to avoid them: While the left one was quite satisfactory in terms of speed and stability, it simply didn't have the range to make it all around Laythe. The right one had IRSU capability, but at a top speed of about 85 m/s it was a bit on the slow side. The final design can refuel itself, is very stable up to 110 m/s (although it can go considerably faster), all while being quite manoeuvrable on land as well as at sea. 110 m/s may look like a lot, but considering that conventional boats easily achive 30 m/s, at 4x physics warp they are faster than this design since time acceleration is a no-go for hydrofoils. Still, I prefer this approach because speeding along, barely touching the surface is something strangely pleasing in itself. Besides, why choose the easy route when there's a complicated way to do it? Here's the craft on a low-fuel test run on Kerbin: Now the big day has come - on top of a launcher, the Speedboat IV sits on the pad: The launch vehicle is capable of SSTO. This avoids the hassle of assembly in orbit, although it forces me to refuel before sending it off on its journey. Coming up next: From liftoff to splashdown Edit: Craft Link: https://kerbalx.com/Chemp/Speedboat-IV
  15. Welcome to my Elcano Challenge thread! My goal is to sail and drive around Kerbin, going over the poles and seeing some cool stuff along the way! This is where I'll document everything on a daily progress basis, and where you can all enjoy the trip along with me! The Ship The ship I am using is the best of the best (not really), a Ship Mk1 model complete with loading gantries, helipad, bridge and crew quarters! Cruises at around 60 m/s after some of the fuel gets used, and best of all? It can drive on land! Yay! Her name's RV Evergreen! Here's a picture of it when she was launched: The Route Surprise! I'm going totally off of my best hunch and what I can see from the ship on this one! No plotting of routes for me, I'll just go where it feels 'right'. That said, I'll mantain a map of where I've been so far, which is here: The Crew We have a specialized crew of 7 Kerbals onboard The RV Evergreen, which is really to say all the personnel we had at the KSC at the time. The crew is ready for any eventualities that we all know will strike sometime during the trip! Their names are (in order of importance to the mission): Captain Sparrow - Captain of the ship! Commander Awesome - The adventurer! Jozie Kerman - Helicopter pilot and scout! Pine Kerman - Jeep driver and lookout! Sandisk Kerman - Cook! Carly Kerman - Mechanic! Lia Kerman - Comms interpreter! The Ship's Condition: I expect the ship to get banged quite a bit during this trip, so this is where I'll list any issues it has and an image of it at this very moment! As of now, the RV Evergreen has reached the first milestone of the trip: Reaching the on-ramp to the south pole ice cap! So damage to the ship yet, but the ships wasn't as efficient as I feared, and is almost out of fuel now. The plan is to land a refueling plane nearby and refuel. Original early post:
  16. Hello all you forum users! I am currently planning my first Kerbin Elcano challenge, and I am super excited. Most of the trip will be on water, because the land is too rough, but that doesn't matter. I am in development of a mark2 hull based pontoon boat, with an outer deck, seating for 6 Kerbals, solar arrays on the rear, and ore harvesting equipment. Man, I wish I had photos, but Flickr isn't working yet. MODS I PLAN TO USE: KAS, KIS, Ven's stock revamp, (for textures) KER, MechJeb, and MK2 expansion. Anyway, when I get some shots up I'll showcase my craft. Thanks for visiting my little corner of the forums!
  17. speedboat? hydroplane? ekranoplan? Elcanoplan! Kerbin sea circumnavigation - as much travel over water as possible (but a part of the route will have to cross the land) Start point: Just drove off the runway and into water Engine engaged, raising onto hydrofoils, reaching the cruise speed and let's go! Phase 1: Northeast island Distance: 141 km MET: 0:55-2:11 Land! Looks like a nice bay And crawling out of the water. Not that much fuel spent, but let's fill the tanks And after full refueling Let's swim across the ocean! What? Sunset? Has it really been that long? And we are still halfway to the next destination... Phase 2: Cape of Falling Stars (or were those actually spent stages?) Distance from last point: 244 km (242 km) Total distance traveled: 385 km (383 km) Distance from KSC: 359 km (354 km) (numbers in parenthesis are straight-line measurments before accounting for curvature) MET: 0d 3:39 Land? Not just land - the end of a continent! Crawling ashore right on the cape Between two oceans We have enough fuel - let's no waste the night. And further east! Phase 3: Good morning island! Isn't it a good sign to find an island on sunrise? And right near a cape from a big continent! Distance from last point: 297 km (294 km) Total distance traveled: 682 km (677 km) Distance from KSC: 647 km (616 km) MET: 0d 5:10 - 1d 0:54 Sun! Land! Marching ashore A well deserved shore leave Reached a new continent! Not a continent? Slightly offshore? Still a nice island! OK, now we are refueled And set course northeast! Phase 4: Owl island White Owl once considered building an airbase there to land reusable boosters. He was using modded space center location - on the continent west of this island. Distance from last point: 397 km (390 km) Total distance traveled: 1079 km (1067 km) Distance from KSC: 939 km (846 km) MET: 1d 3:00 And the Sun set halfway there again... Choosing a good beach And we are here! Longest single glide so far! Well, we still have half of total fuel capacity and half the night is still there... Let's move on (and hope we don't run out of fuel) Phase 5: Crack gulf cape Distance from last point: 370 km (364 km) Total distance traveled: 1449 km (1431 km) Distance from KSC: 1225 km (1023 km) MET: 1d 5:07 - 2d 0:51 Looks like we got there! Drop out of glide, switch to swim and get on the beach And into this gulf our path goes next 767 km covered since last refueling! And by the time we got here, morning reach our previous stop. But we saw the sunrise halfway here. Let's just fill... What? Sunset?! Already?! But we mined just half the fuel! Okay, let's move on. At least we aren't crossing an ocean this night. Phase 6: Landcrack gulf This place really looks like if somebody tried to tear the landmass apart. Distance from last point: 100 km Total distance traveled: 1549 km (1531 km) Distance from KSC: 1287 km (1054 km) MET: 2d 1:25 Cruising inland along the shore Is that ..? Yeah, the ocean has ended We have run out of water Kind of... Land is full of lakes
  18. ELCANO CHALLENGE - ACCEPTED Prologue _______________________________________ Many intrepid adventurers have set out to explore the solar system, only a few have attempted to drive or float their way around the entire home planet. Well, perhaps rashly, perhaps ignorantly, I'd like to try. I received much pleasure from reading others' attempts at this, successful and otherwise and hats off to you, I have great admiration for your achievement. I'm not a patient or faithful person. So I'm concerned, but on the other hand, hopefully this is an opportunity for growth, even if in only a small way. If I fail, at least I will have tried. If I succeed, hopefully I will have had a great adventure, gotten to know Kerbin better, be a better engineer, conquered my own laziness and lack of constancy. At this point I'm planning on majority sea travel, with a couple of small trips across the land bridges. We may need to modify our plans as we go. Pre 1.1 sea travel was a much more impressive accomplishment. So I'm taking the easy option in a sense, but hey at least now it's achievable for the likes of me! _______________________________________ CONTENTS 1.

Vessel Overviews The Waarn _______________________________________ DAY 1 Prototypes and Explosions _______________________________________ Design Thoughts: Two different schools of thought on Elcano. A car that can swim or a boat that can walk. The great blue yonder beckons... Several different experiments in the SPH resulted in a catamaran type hull. With more parts touching the water there is more drag I think, however I found with longer outriggers/pontoons the craft is more stable. The goal here for me was being able to run this craft stably at 4x speed with physics. So to that end I set off on a sea-worthiness trial and managed to cross the Eastern Sea by water, for the first time! Amphibious! Land! Check it out Jeb! _____ Bill: " Hey, Jeb, can I come out too?" Jeb: "Ummm. No. Maybe you can get out next time." Bill: "Flip." Jeb: "You're just the engineer after all. You were drinking cokes in the back seat the whole way here, while I was doing all the hard work!" Bill: "..." _____ Name: Always important. Embody the ethos of the mission; inspire the adventurers. Being stumped, I asked my wife, who took one look and said: "it looks like one of those spiders that walk on water" 1 minute of googling later,,, Behold!: The Dolomedes Triton! The namesake is an spider which is known to run on water - hence the reference to Poisidon's son - and even 'fish'. How apt - a sort of amphibious arachnid. Additionally it's coloring's are similar. Drag: So, this craft is efficient enough. Having experimented with different nose cones I found the NCS + small nose cone is pretty efficient. -Further, interestingly the 'straighter' or more level the craft moves through the water, the less drag. Having long pontoons seems to level out the craft and enable higher speeds. Additionally the vertical stabiliser helps with a little snaking in the water which knocks off speed too. -Fully loaded this craft can cruise at around 25 m/s. I realise this is no speed boat. But I think this speed is acceptable, and more realistic this way. -Having small wheels housing clipped into the pontoons seems to make no difference to drag. Funny, I thought it would. This is good news, as it means more ground clearance underneath for those nasty hill crossings. Engines: Also the Juno engines, whilst not as efficient as the Wheesley are better suited to this craft. When trying the Wheesley, the higher thrust meant the craft tipped more with the center of thrust higher than the center of mass. With the smaller engines this is not a problem. The center of mass needs to be low down so it doesn't tip, so the pontoons are the primary fuel tanks. On returning from the sea trials... Next thoughts: Wheels: Overland small landing gear + the Junos should get me there for the land bridges. But I'm not so sure about this. This is probably what I'm most worried about. Before I set off, I definitely need to test thrust going uphill. Might need the Wheesley after all...or moar Junos (*lol*). Surveying: To that end, aerial survey will be in order. I'll fly to the two proposed land sections which need to be crossed and check their inclines and plan out the ingress and egress points. Fuel: The on-board fuel load gets the craft pretty far. In one test I went 335km and used 1,079 LF, which was only a small fraction of the tanks capacity. Even so, as with most Elcano attempts, a refuel will be necessary. I'm thinking a cargo-plane drop of a refueling rover (read orange tank with wheels!). Or possible a VTOL plane could be fun. I've recently discovered these and they can be quite fun. Regarding the actual refuel connection...To Klaw or not to Klaw that is the question. (Last time I seriously used the Klaw 'round Minmus to recover a lost capsule the Kraken was awoken and ate my game. Ships in orbit started accelerating. Nasty. Nearly lost my whole carerr save game. Fortunately I'm a little OCD with backing up.) Logging: Don't really want to have to manually log lat./long. The old Persistent Trails mod is not up to date, so that's out. Up Next: ...Land Trials & Refueling tests!
  19. About the Mission: Primary Objective: Complete the Elcano Challenge circumnavigate Kerbin without leaving the planet's land surface or oceans - SUCCESS Secondary/Operational Objectives: complete the circumnavigation in as little time as possible (this means ISRU stops are out of the question) - PARTIAL SUCCESS (24 hours 44 minutes) based on craft performance, this conditionally means one fuel stop only - FAILURE keep land-based transportation to a minimum - SUCCESS The Craft (CRAFT FILE HERE) The Soviet 3b "Elcano" is a tri-hull catamaran-hydrofoil capable of speeds up to 100m/s, with a maximum fuel capacity 40440 LF and a maximum crew capacity of 10 (or 4 in comfort). It is powered by two J-90 "Goliath" turbofan main engines, and 3 auxiliary J-33 "Wheesley" turbofan engines, providing a variety of thrust patterns for optimal speed and/or efficiency. Directional control is achieved by paired aero- and hydro-rudder surfaces (AV-R8 Winglets) mounted aft on the outer pontoon-hulls. The 4 hydrofoils themselves are 2 pairs of FAT-455 control surfaces mounted anhedrally to the 4 wheel-pod hardpoints. At a maximum of 50% fuel capacity and speeds exceeding 50m/s, they provide adequate planing lift to hold the whole vessel clear of the water, and must be dynamically trimmed by the helm to maintain direction stability and prevent porpoising. The parent design process was originally intended to result in a non-stop circumnavigation, but due to operational constraints and time pressures the mission was forced to launch before such a design had been achieved - under near-optimal circumstances, the Soviet 3b can only be expected to cover half the planetary ocean surface without refuelling.

  20. So I've been thinking of doing the Elcano for a long time. I planned to do it when I was playing career mode with a Duna rover. I also wanted to do it on Dres which is one of my favourite planets in the game. So here is my Dres Elcano. Drelcano? Nope. The Rover Meet DEV or Dres Exploration Vehicle. It has room for two kerbals on top. Very durable. (Unless you crash into a building hence the broken rover wheel) The Mission Now let me explain how I intend to do the challenge. First I get it to Dres and land it. Then I drive to a lander that I landed a few months back for the Dres Awareness Challenge. This is where I pick up my crew. I was thinking of doing an equatorial circumnavigation so I could pass through the Dres Canyon however that is for another mission as I will most likely re-use the DEV for future missions. Therefore I'll then do a Polar circumnavigation and then come back to the lander again. If any un-fixable accidents happen, I'll have to send another rover. (Obviously ) Part One Getting the Rover to Dres. So I built a big launch vehicle instead of going for a small nuke powered one. I love it when you use flea boosters as seperatrons. From here, I had to first go around the Sun once more to get the Dres encounter, got a crazy high capture burn and had to do a scary suicide burn and ended up using the transfer stage as a shock absorber. Ok lets go pick up Billy-Bobsen and Linke Kerman. They're quite far away... I wish this counted as part of the circumnavigation. :/ And that's what became of the first flag on Dres... Anyway that's it for now. Next we'll reach them and start the circumnavigation!
  21. Elcano is the hip thing to do nowdays, it seems. Here's mine. 11 July 2016 : Initial Design Before the original Elcano challenge was posted in 2015, there was the no-rules circumnavigation challenge. Unlike Elcano, where the spirit is the most important part, the no-rules circumnavigation challenge was all about results. I decided that instead of circumnavigation using depressed trajectories and rockets, I decided I was going to do a water circumnavigation. I got about halfway around Kerbin before deciding to do other things, then KSP changed parts and all hope of completing that circumnavigation was lost. This circumnavigation attempt can be read about at its original post. Even though I stopped, and I can no longer complete the original circumnavigation that I set out to do, I still want to complete a water circumnavigation. Through last night and this morning, I worked hard on designing a ship that could work as well as my original ship even with the new water physics. Here are snapshots of that journey: 12 July 2016: The first leg What a wild first leg I had! The journey can be divided into three parts: High-Speed Watercraft long pontoon, Inasta and Inasta II, and Inasta III. The first leg was High-Speed watercraft long pontoon, the test boat. High-Speed Watercraft long pontoon made a good first leg but was not fit for a full circumnavigation because kerbals cannot re-enter the craft if they leave, which makes flag-planting impossible. Also, the proper opening ceremony had not been made. I officially start the circumnavigation with Inasta. Alright, so, actually Inasta II was the real start of the journey because it's the only one I haven't lost progress on, but I already need to send a recovery craft. Finally made it to the end of leg one. 13 July 2016: Refueling before the second leg I present to you General Refueling Aircraft, purpose-built to refuel Inasta III (yes, I know). Stage separates the klaw, 1 toggles klaw arming, and RCS toggles reverse thrust (R for Reverse Thrust of course). The design shown is actually the second iteration, as I have no pictures of its first iteration. The only difference is the addition of struts on the wings. Lets refuel Inasta III: Hopefully I complete this voyage before I die.
  22. So about a year ago, maybe a bit less, I circumnavigated Gilly. Back then I was a relative amateur at KSP, and the entire thing was shoddy, but nevertheless successful. However, looking back, the reason I chose Gilly was because I was worried about doing damage to the wheels. Once I got there, I was more worried about making orbit by accident. While I don't trust myself to create a ship capable of reaching Pol, the 2nd smallest body in the game, I do feel confident to go to Minmus. I'll submit several 'Chapters' in the form of IMGUR albums to showcase this. So, without further ado, I present Chapter 1! Apologies for no info on the album, I'm not sure how to add captions to each bit, any advice is kindly appreciated.
  23. Ahh, yes. The classic drive around somewhere challenge. I have decided on Eeloo as my target. I have landed close to its Apoapsis, which means the sun is small and output is small. But, I brought 2 RTGs to generate power! This should be easy, and fast. A snowball sized like the Mun is an easy drive. Or is it really? DAY 1: Rough Driving We have landed on Eeloo. We have already driven 27km from the landing site. The rover is not it tiptop shape, but it still works. We are going to push on. Valentina will ace this drive! Day 2 is obviously tomorrow! Day 2: Not so small steps We have driven so far today! Both the landing site flag and the flag in the dirt are both gone. We have entered and driven out of an abyss. The rover has ended up on the dark side. Nothing has been lost. We will keep going. I might add another one today. MIGHT ;] I felt lazy so no titles or descriptions. You decide what happened today. Day 3 or 4 Part 1: Halfway Halfway! We have made the mark. Only another half and it's all over. It's not boring, it's just taking a while. Also, no titles or descriptions for these 45 pictures. Why part 1? Because there will probably be another part tonight. I have become obsessed with finishing this challenge. I can do this. Day 3 or 4 part 2: Game Over I did it. 210km driven. The snowball has been conquered. All I need to do is rescue her. I probably won't, to honor here. It's finally over. Here it is. 66 pictures with no titles or descriptions again.
  24. MUN ELCANO RUN This is an attempt of mine to go around the Mun by ground. Summary of past events (bolded numeral indicated which chapter is summarized): CHAPTER I: TO DRIVE AROUND THE MUN, ONE NEEDS TO BRING A CAR TO THE MUN The rover was designed to be simple, durable, reliable, and stable. It was tested around KSC and works pretty well, at least in Kerbin's high gravity. I expect it to be able to keep going day and night, and it has proven itself able to go up some pretty steep hills (namely, the side edge of the end of the runway). The only drawback to it is that it's simply awful to transport. I had to build a really awkward rocket to get it to the Mun, and it took a really long time to get it just right. It didn't quite have enough delta-V, it always decided to RUD when separated from the rover, and the rover's engines were pointed towards the crew module, which cancelled out the thrust because PHYSICS. Here is the rocket as I first designed it: And here is the rocket which actually made it: Landing: In the process of getting a rover to the Mun in working order, Jeb was stranded. This is not a problem, as I'll just drive the functional rover to his location and pick him up. The rover is currently landed on the Mun, I will post pics of it later when I start the driving.
