FOREWORD After Reactor 4 of the Chernobyl NPP exploded, large amounts of rubble, graphite moderator and other radioactive material from the destroyed reactor were ejected onto the roofs of power plant facilities. Radiation on some parts of the roof was so severe that unprotected circuitry used in remote-controlled robots failed near-immediately. To continue cleanup works rubble needed to be removed from the rooftops. Since the radiation levels would give human workers lethal doses in a matter of minutes, robotic solutions were in high demand. One of such solutions was a repurposed lunar rover (named STR-1), a remnant of the Lunokhod program outfitted with dosimetry equipment and a bulldozer blade. It's circuitry was already hardened against cosmic radiation, and such it could be quickly modified and deployed into the containment zone. Even with this protection, it only managed to clean up a couple dozen square meters of the roof before succumbing to the extreme radiation. In this challenge, you will take on this exact task. You will develop a rover with limited operation time which will help remove graphite rubble from the power plant site along with a delivery method. THE CHALLENGE The cleanup operation will consist of four major phases. 1. Rover delivery Taking off the KSC airfield, you will need to deliver the rover to the disaster site. Time will be counted with the in-game clock from the mission start to the moment, where you come within 150m of the reactor (when the distance marker disappears). In this case, the quicker the better. Point assignment rules will be elaborated on in the next section. 2. Landing your rover on the roof Since the radiation levels near the core are extremely high, you will need to minimize your time in the proximity of the reactor. From the moment of your arrival within 150m of the reactor you will have two minutes in-game time to deploy the rover onto the roof and leave the 150m perimeter. 3. Retrieving the carrier craft This section will not be timed, albeit additional points will be awarded if you can return your carrier craft to the KSC unscathed. 4. Cleaning up the roof After your carrier vehicle has landed (or crashed horribly) you can begin your operation. This section is not timed - the only limit being your battery life (to simulate radiation exposure). Points will be awarded based on how many of the 10 graphite blocks (Oscar-B fuel tanks) situated on the roof you can remove before your battery dies. The blocks are supposed to be pushed off the edge of the roof into the destroyed reactor building where they will not pose a threat. The challenge ends after your rover battery dies. RULES As with all challenges, here are some rules: 1. Your carrier craft can be a VTOL aircraft, a helicopter or even a land-based vehicle. The choice is yours in that regard and creativity in the delivery method department is greatly encouraged! 2. Your rover's only power source can be a single Z-400 battery. All other power sources such as your control modules are prohibited and need to be emptied in the hangar. 3. You may not use any power producing parts such as solar panels, fuel cells and RTGs. 4. The rover has to be delivered onto the roof via the carrier craft, e.g. it may not be deployed outside of the 150m perimeter and flown or driven onto the roof. 5. Albeit the graphite blocks may explode after being dropped into the reactor, they may not be exploded directly on the roof as a mean of their removal. 6. Using kraken drives to propel your rover is prohibited, as the whole point of this challenge is dealing with the problems within time and resource constraints. 7. Please let me know if your submission is stock + DLC or uses some other mods for ease of organization 8. For obvious reasons, the rover must be unmanned. No Kerbals can come close to the reactor, they are already green enough as they are. The points for each section will be awarded according to these rules: Section 1 - Delivery Number of points is the value of the following function: ceil(max(300 - your_time [sec], 0) / 2) Section 2 - Landing the rover Number of points is the value of the following function ceil(max(120 - your_time [sec], 0) * 4) Section 3 - Returning the carrier craft Number of points awarded is 40 - if the carrier aircraft is landed undamaged at the KSC 0 - otherwise Section 4 - Clearing the roof Number of points is the value of the following function 100 * blocks_removed HOW TO SUBMIT YOUR ENTRY First, you should download the savefile containing the powerplant set up in the correct spot. It can be found here: https://filebin.net/h67zuoh36flmrfpz Afterwards, after creating your entry you should either film your run, or document it via screenshots. If you choose to go with the screenshot route, please provide the following: 1. Screenshot of your crafts on the KSC runway at the beginning of the mission 2. Screenshot of your arrival within the 150m perimeter with the HUD enabled 3. Screenshot of your carrier craft departure with HUD enabled (if you choose to retrieve it) with the rover on the roof visible in the shot, or just a picture of the rover on the roof if your delivery method is expendable 4. Screenshot of your carrier craft landed (if you choose to retrieve it) with HUD enabled 5. Screenshot of your rover on the roof with amount of electric charge remaining at the beginning of cleanup visible 6. Screenshot of the roof after your electric charge runs out with all remaining graphite blocks visible If you have any questions regarding this challenge, feel free to ask them via messages or here in the thread itself. Have fun and good luck on your journey. If you feel that any of the rules or point awarding mechanisms need tweaking please let me know! Be wary that the power plant building contains almost 1100 parts so you may experience quite a bit of lag. This is kind of offset by the fact that the model is static and the game does not seem to lag quite as much as with most mobile spawned high-partcount crafts. With a GTX1050 and 8GB of RAM I was able to keep the FPS at about 20-25 at all times and I could execute the mission without too many lag-related issues. I will prepare a proper badge for all participants and will post it here in a few hours. Cheers. c: STOCK LEADERBOARD 1.

Show off some of your best helicopters, stock and modded. i am working on a Bell UH-1 iroquois, downoading breaking ground to make a custom rotor using servos and rotors. does anybody know any good mods for small arms weapons like a 7.62 machine gun?

We have a small problem The seas off of the Kerbal Space Center is getting quite cluttered with spent stages and solid rocket motors that have splashed down into the ocean. Lately some of the higher ups in the research and development offices have had a radical idea: "What if we recovered our first stages?" After so heated arguments with the engineers who said it just can't be done, they have turned to you! The Challenge: Recover the first stage of your rocket (this means SSTO's don't count). You can do this however however you see fit, whether you want to land the first stage on a barge in the ocean, have it glide its way back onto the runway, or do something completely crazy! I want to see your ideas on how to recover a first stage, the Kerbal way. Points for this challenge are awarded as such one point: your craft is able to land its first stage safely two points: your craft is able to land the first stage near the KSC' three points: your craft is able to land the first stage on the runway/ launchpad four points: your craft is able to make the first stage land on the island runway five points: your craft is able to land the first stage on a barge/mobile landing pad you have put somwhere BONUS POINTS you will be given an extra 3 points for each of the following you are able to land your second/third/fourth ect stage/stages as well as your first you land your first stage using only SRBs you land your first stage using propellers you refuel your first stage and have it meet back up with the second stage or whatever stage is in orbit you recovered not only the first stage but any liquid/solid boosters that assisted it Hope to see some cool designs Leader Board 1: sevenperforce 11 points (two for landing near the KSC, 3 for recovering second stage, and considering how he refueled and rebuilt the ship I am giving him 6 points there) 2 3 4 5 -AtomicSnails

I got around to building a really nice ship... But it was too big. So, I made a smaller one, and it looked better than the bigger one! Behold: The DA-SR2! https://drive.google.com/open?id=0BznEolcLuLIlSUZLMVgwVDJqRFU

Been playing the demo, and it is pretty limited, but I wanted to try and do a lunar landing with a rover. Only, there are no wheels in demo. So I had to get creative. First rover test: So far so good... Uh oh. Okay this was a bad idea. Back to the drawing board. Let's make it a bit less explosive. These reaction wheels don't have quite the jazz of jet engines, but they get the job done! I use roll control for forward and reverse. Turning is tricky; you have to use W and A, but since the rover is constantly spinning, pressing W turns different ways based on where you are in the roll. Thankfully, it's pretty slow, so you have time. Seems quite capable. You can even recharge it: Oh, wait, these panels aren't retractable. So once you start to move, they snap off. Guess I'll need to mount them in a better place next time. Figured I'd head for the water to see whether it would float. You can get a bit more speed if you're going downhill. Will it sink or swim? It swims! Not very fast, but it does. It can even recharge in the water without the solar panel snapping off! Though I need to fix the configuration anyway. Off we go! Now to mount this bad boy on a lunar lander. In Demo. This will be fun. EDIT: Fixed those solar panels. They work much better now. Should even give me a little extra boost if I go back in the water.
