  1. Hi. I see from a vessel enumeration run in an almost new career game that there are some asteroids up there already. Are more asteroids spawned as the game progresses? Do they keep spawning? Are they ever removed? My intention is to 'identify' one or more asteroids as 'interesting' for contracts. I guess the contract could spawn the asteroid, but it seems like a cooler solution to pick one of the the already spawned ones, if there is a good one.
  2. So I poked around in the Tracking Station, and saw not one but TWO Kerbin-intercepting asteroids. I was thinking of watching them come down, but since Kerbin was rotating I had no idea where it would come down. Anyway, I overdid the time warp and they both impacted and disappeared off the radar, without me seeing where they landed. All I know is that it's somewhere around 50 degrees north. Is there any way I can locate them? Would my orbiting survey scanner be of any use? Would I see a dot of ore concentration? It has a short band, surface scanner, everything.
  3. ReMeMber the KANTERBURY ! Ice Hauler from The Expanse; Stock Kerbalified. Oye Beratnas, Kanterbury be chowing A'rocks all cycle long. The SAS is pomang kaka so use your RCS for fine navigation, sass? Kewe to pensa? For the Earthers: This is a sort-of-replica-what-I-call-Kerbalified-version of the Pur'n'Kleen Ice Hauler Canterbury, from the series "The Expanse". While it's designed to look (nearly, but not quite unentirely) like the ship its based on, it is at The Expense of making the thing work reasonably efficiently in KSP. So, part count is a low, low 200 It's those damnable RCS ports. I've kept everything else to a minimum to keep that count down; there's plenty of room for improvements on this vessel if you've got a computer to handle it. This thing will probably accommodate at least four Class A 'roids, maybe even six but for now there's just two grabbers. With the launcher this comes in at pretty hefty 372 parts. Fortunately by orbit you'll have ditched 172 of them. Mechjeb can get this thing to a circular 250km orbit without too many issues, though you will need to help steer the nose to the correct heading a little if it starts to tilt away from it. Don't forget to 'Control from here' on the command core (as pictured) before launch!

  5. Star Shooter KerbalX craft File here! So I made this rocket because I thought it would be a fun challenge and I've not really seen anyone do such a thing before. The first challenge came when I realized the "payload" would need to be placed near the bottom of the whole setup for purposes of easy attachment (I didn't want loading the Asteroid to be a complicated task). The 2nd hurdle was that the forward tank and engine nacelle would need to eject FORWARDS during flight and would need to ACCELERATE faster than the ships current speed to get out of the way (trust me it took way more tests to figure that out than probably should have!). The solution to this is to release the Front Tank/Engines when fuel is about to run out. The tank naturally accelerates forward and downwards safely clearing the path for the Star Shooter. During Stage 2 (tri-rocket configuration) you can fly to a stable orbit, or ditch the outer rockets so they can burn up in the atmosphere and continue your circulation burn on the Stage 3 dual Thud motors. I like to fly this rocket at half throttle until stage 2. After which full throttle is just fine. So far I've only tested it with a Class B Asteroid (technically meteorite) that weighed a mere 6.5 tons. I would be confident in payloads up to about 15 tons and of Class B asteroid size or smaller. Try it out and check out the video if you aren't convinced! Let me know what you think of her!
  6. This challenge is fairly self-explanatory - there are two modes - Armageddon mode and Deep impact mode. In Armageddon mode, you must create a space shuttle, and rendezvous with an asteroid, redirect it into Kerbin orbit, and (safely) return. Refueling in orbit is allowed. In Deep Impact mode, you must construct a spacecraft in orbit; one that utilises a space shuttle cockpit (Mk-1, MK-2, or MK-3 plane cockpits), and is capable of not only redirecting an asteroid into Kerbin orbit, but into LKO. This is so because, let's be honest, building a spaceship in orbit just to redirect an asteroid is complete overkill, so I added some extra difficulty. Mission goal: Rendezvous with an asteroid and redirect it into Kerbin orbit. +20 points. Armageddon mode general goals: Realism 1: Make your space shuttle NASA style, ie: the shuttle mounted on the side of an External Tank, with two SRBs on the side. +15 Movie Madness 1: Have two small SRBs on the sides of the shuttle itself to help boost it into either the orbit or to help with the rendezvous. +10 Movie Madness 2: Use a gravity assist of the Mun to help reach the asteroid. +15 Michael Bay 1: Blow up the space station you used for refuelling (if you used one). +15 Crew Safety 1: Include some form of launch abort system on you shuttle. +5 Movie Madness 3: Keep on using you SSMEs (Space Shuttle Main Engines) even after you've ditched the ET. +5 Crew Mobility 1: Include some form of rover in the cargo bay of your shuttle (even though you don't need it). +10 Big Dreams: Use RSS or some other large rescale: Multiply your total score by 5. Impress me: Points determined from how impressed I am. Deep Impact mode general goals: Realism 1: Build you spacecraft in orbit using NASA style space shuttles (see above) and Russian style rockets (I won't be that specific, but make sure it looks like the Proton, has 3 stages; the 1st stage has 6 engines, the next has 4, and the last stage has 1). +15 Movie madness 1: Use the nuclear engines as your main form of propulsion. +10 Aesthetics 1: Have two SRBs mounted on the side of your spacecraft, even if they have no purpose! +10 Crew Safety 1: Have some form of escape pod on your spacecraft. +5 Crew Accommodation 1: Have a crew capacity of 8. +5 Big Dreams: Use RSS or some other large rescale: Multiply your total score by 5.

  7. http://www.space.com/36404-asteroid-2014-jo25-earth-flyby-coming-april-19.html The asteroid 2014 JO25 will come about 1.8 million kilometers from Earth on April 19, and should get to an apparent magnitude of about 11 at it's brightest. Here is a map of it's path through the sky: I'll try to observe it's motion with a telescope. I've never seen an asteroid before!
  8. Hi guys. So i'm baffled as to where my resources are going? i'm mining on a classE as i plan to take it to Gilly, and in 1x speed the resource weight from the asteroid goes down. and the weight of the ore tanks fills up. Great. All fuel on my ship is already full. the only thing to fill up are the ore tanks. when i timewarp to 100 1000 10000 etc the speed at which the resources drop from the asteroid begin to increase, as you'd expect. but the speed at which the tanks fill up slows to a grind and ultimately stops??? on my convert-o-tron unit, no ore is being converted to anything. everything is stopped. i have no idea where the resources are bleeding off to? i'm over 300 hours on ksp with solid mining experience never seen this before. the mining equipment and tanks are all stock parts. only engines/decals and other parts unrelated to the mining process are modded. is this a bug? Please help! Thanks.
  9. I'm pretty sure I can change the texture on an asteroid, and I know how to dynamically change textures in KSP, but does anybody know the name of the transform for the asteroid model itself? Basically I need the name of the mesh so I can call SetTexture on the Renderer. Also, what is the name of the texture file for the rocky asteroid texture (and for that matter, magic boulder)? Anybody know? @JPLRepo, can you shed some light on this? Thanks for your help.
  10. Hello. I am currently playing with asteroid and I have an issue with attitude control of one of them. I have USI Asteroid Recycling Technologies installed. This mod modifies the mass and density of asteroids as so they are bigger and denser than stock (a C'ish' asteroid becomes big as an E'ish' one and so on). In order to steer the asteroid I have placed 2 ships on the opposite sides of it and they are equipped with a lot of RCS. When the ships are detached the RCS is behaving like it should but when they are attached to the asteroid not even a single drop of monopropellant is used and I have to rely only on reaction wheels for attitude control. How is that? Is there any option that can enable the RCS to work even when attached to an asteroid. As a side note I would like to stress that I do have Mechjeb installed too and I tried fiddling with its options but to no avail. Thanks
  11. The mission is aimed for exploring 2 asteroids and 1 dwarf planet with an unmanned craft This is the craft you need: it needs scientific instruments ,an individual engine and powerful antenna ,just try to make it as small as possible,okay? Your first stop will be an asteroid You must flyby 15 meters above the surface of it Next step is to flyby Dres .Your periapsis must 75 000 m above Dres. And the last place to visit is Gilly ,you need to establish an orbit around it with periapsis of 55 000 m The difficulty varies in type of propulsion you use! Ion propulsion is hardest, Liquid fuel propulsion is normal,and non individual (another stage with engine) is easy. And remember kids NO CHEATS!!!!mods that dont brake the challenge can be used ,it is not considered a cheating!You can still change route if you want so....But you still need to visit all 3 of them!GG have fun
  12. Reading an article on fast spinning asteroids, I thought about the possibility of anchoring a habitat and refining complex to such a body with a tether long enough to create useful artificial gravity. The next thought was to tether two asteroids together to make a dumbbell spinning around a common center of mass. Suddenly all the problems of weightless mining and materials handling are moot. Each asteroid can be treated as if it were the top of a mountain, and all directions are down. However, , there is the problem of manoeuvring megaton masses into close proximity. Then just the other day I watch Cody repair a broken Crooks tube and I had a couple of ah-ha moments in one. Lace a contact binary asteroid into a pair of nets/bags with the mouths toward each other. As the asteroid spins, apply a thin layer of ice to the widdershins side of each half of the pair whilst it is in shadow, for the sun to evaporate as it rotates into light. Unless I'm completely mistaken, this should slowly accelerate the asteroid's rotation, eventually causing the two halves to separate. Coating the spinward sides with a material that is efficient at both absorbing light and re-radiating it as heat, adds in the Yarkovsky Effect. Slowly lengthen the "laces" until gravity is sufficient for mining. My guess is 5-10% of Earth normal gravity would be sufficient to hold machinery "down" and keep liquids settled in covered and suitably baffled containers. Has anything like this been considered seriously? Would it work?
  13. Hi Folks, first time poster, long time lurker, so please be gentle. I've recently accepted a mission to tow a Class A asteroid into Kerbin orbit. Except: I can't find any class A asteroids. I've got class E (huge) right down to Class C (Medium) but no class A asteroids. There are about 7 asteroids visible from the tracking station. Question: am I missing something? Do I need to send out a scanner, or just wait until a class A asteroid meanders into tracking station range? For info, I'm playing career mode with kerbnet on and standard difficulty settings. Thanks in advance!
  14. I was not sure where to put this and this seemed to most relevant place. If i'm wrong i do apologize. In 40 days an asteroid is going to impact Kerbin. I want to catch it and put it in a stable orbit to use as a mining station for re-fueling. So I need a ship that can grab it, divert it from an impact then maneuver it into a stable orbit around Kerbin. I am probably going to have to assemble it in orbit, one section at a time with docking ports but aside from that i just don't know what to do. Any suggestions?
  15. I would like to know, but don't know where to look for the following: Weight of all asteroid classes Total ore in each class I plan on, or am hoping to be capable of taking asteroids to the surface of Kerbin, and then relaunching them into orbit once again, just for the fun of it.
  16. Hey. Novice kerbonaut here. I took on a contract that required me to capture a class E asteroid around Minmus. Many brave kerbonauts have tried and failed. (6 to be exact, 2 died whilst performing an aero braking maneuver, far too early along the tech tree) in trying to maneuver a 1900 ton monster of a rock which could be used as an orbital refinery. At this point I'm a year away from failing the contract, and the encounter occurs in 200days. I figured I'd mine the ore out of it and capture into Minmus. But the question remains. If I mine an asteroid to its empty mass, does that change its class? Any answers are welcome
  17. Asteroids personally should have a real impact on the planet its hitting (Kerbin) You know how 1.2 (or sooner, idk) introduced procedurally generated craters on the Mun? Why not make it to where when an asteroid hits Kerbin. It adds a procedurally generated crater! Aswell as particle effects to the asteroid entering the atmosphere and on impact, add a texture of the impact like this. And after a minute or so it looks like this So it looks like it cooled down. The real reason i'm asking for this is because I think this would give a better point to redirect asteroids. I will not expect this feature to be added anytime soon. But i'm just asking for asteroid realism. Simply because right now there really isn't any point in redirecting asteroids. This would give a real point to redirect asteroids. So us, the KSP community, can have some fun redirecting asteroids. - Sincerely, KerbalMan32
  18. I'm planning my first asteroid capture mission, and (without having played the tutorial mission) I got curious to learn how much fuel and thrust I would need to put on the capture vessel in order to bring the asteroid into a useful orbit around Kerbin. I spent a lot of time trying to learn something about it, and thought I would share. I would really love to hear your thoughts and feedback! The lovely little space rock I have in mind to make my own is one SDD-569, a class A asteroid. SDD-569 is approaching Kerbin for a leisurely flyby at a periapsis of ~2,079 km, well inside the orbit of the Mun. This puts SDD-569 into a sharply looping orbit around the planet, before it flies back out into parts unknown. I'd like to drag the asteroid into a circular orbit, and then bring it down to about 500 km for future research and exploitation. Can we calculate how fast is SDD-569 going with respect to Kerbin, based on what we already know? Since energy is always conserved, the total kinetic energy for a given object (from orbital speed) plus its potential energy (from gravity) never changes. The relationship of kinetic energy to velocity is a consequence of Newton's third law: In other words, for a constant mass, v2 is a measure of kinetic energy. The vis-viva equation describes the conservation of energy for a small body orbiting a much larger one: GM, also known sometimes as μ, as is Kerbin's gravitational parameter, which the KSP wiki reports is 3.5316 x 1012 m3/s2. This parameter is the product of the gravitational constant of the universe with Kerbin's mass, which is effectively constant. a is the semi-major axis of the orbit as measured from the center of the celestial body. Kerbin's radius is 600km, so we add that to the altitude of SDD-569 at periapsis to give a = 2,679km. r is the distance between the two objects at a given time. An object moving fast enough to escape Kerbin's gravity is in an orbit with a semi-major axis that is effectively infinite. At periapsis, this simplifies the vis-viva equation to describe the kinetic energy that an object must have in order to overcome Kerbin's gravity from a given distance r: In other words, escape speed from Kerbin orbit at the moment of periapsis (r = 2,679km) is ve = 1,623 m/s. But since SDD-569 is tracing a hyperbolic (i.e. open) trajectory through Kerbin's SoI, it must be traveling faster than this, or else it would be captured. How much faster? Consider the other extreme case of the vis-viva relation, where the asteroid has shot past Kerbin and the distance r between them trends towards an infinite apoapsis. Setting r =∞ in the vis-viva equation tells us how fast the object is still going at that point, which is called its hyperbolic excess velocity: (where μ = GM) So for the flyby of SDD-569, the hyperbolic excess velocity is v∞ = 1,148 m/s. This characteristic energy is over and above the energy needed to escape Kerbin's SoI from that distance, so the total energy possessed by SDD-569 relative to Kerbin at periapsis is: This gives a total velocity for SDD-569 relative to Kerbin at periapsis of 1,988 m/s! By how much do we need to reduce this so that it drops into a nice 2Mm circular orbit from periapsis? In a circular orbit, the distance between the two objects r and the orbital radius a are always the same. Thus the orbital velocity is: Not coincidentally, this is the same as its hyperbolic excess velocity, because r = a. So at r = 2,679km, an object in a circular orbit around Kerbin travels at 1,148 m/s. So, to get SDD-569 into a circular orbit from its flyby periapsis, we need to bleed off Δv = 840 m/s. To then bring SDD-569 down to a more convenient altitude of 500km, we would do a Hohmann transfer, which can be calculated with the standard formula, and works out to another 614m/s Δv to descend to a 500km circular orbit, for a total of 1,454 m/s. What’s more, the spacecraft sent to capture SDD-569 needs to match orbits with the asteroid in order rendezvous. That means that if the spacecraft starts from, say, 500km above Kerbin, it will need to expend that much to get to the asteroid in the first place. So, starting from a 500km orbit around Kerbin, the total Δv budget for this mission is 2,909 m/s. Next up: Asteroid capture planning, part 2: How much fuel do we need to bring? Mission to SDD-569: Where the rubber meets the regolith! Did I get this right? If you have feedback or ideas, I would love to hear them!
  19. Recently I have been playing Kerbal Space Program and I was surprised by the random placement of asteroids. This annoyed me slightly as I liked to think of the ksp solar system being like ours. If a large concentration of asteroids were between Duna and Jool it could make navigating space craft to Jool more interesting. Also you could have asteroids of different sizes so you could catch small ones in cargo bays.
  20. I'm working on redirecting a class E asteroid into LKO and have observed that my tug (pusher, actually) is subject to shock heating even though it's on the "shielded" side of the asteroid. I had assumed that the asteroid body would act as a heat shield during aerobraking, but that doesn't seem to be true in this instance. Is this a result of using FAR or is it due to more fundamental KSP physics? Thanks in advance for any guidance you can offer!
  21. So back a few weeks ago I put a mining station on an E-Class Asteroid around Dres. Now I returned and wanted to refuel, but nothing happened. The drill animations are there (including the dust clouds), and they "work", but the ore tank isn't filling up and the ISRU says it is missing ore. The asteroid itself is also not losing any of its resources (90t left apparently). What is actually going on over here?! I thought this may be something that is caused by 1.1.3, but after trying it out in 1.1.2 it still showed the same behavior. Is this a bug or am I missing something? Edit: I have tried mining a new asteroid on a completely fresh savegame (same install, same mods). That worked without a hitch.
  22. Hi all, I've got a bit of an odd question regarding engine thrust. I'm designing an asteroid "puller" to bring in a Class E. I have my nuclear engines out on 4 radially-symmetrical nacelles, which were angled at about 45 degrees to try to clear the asteroid for unimpeded thrust. On my first attempt, the angle was not sufficient, and I had some of the engines (but not all) obstructed by the asteroid, leading to more asteroid-spinning and less asteroid-moving. So to address this, I tried to increase the angle of the engines (i.e., make them closer to perpendicular to the main axis of the ship). I tested out the new design on the launchpad, with gravity hacked and with just the core ship, not the orbital-launch rig. Results were not good- I was barely getting any thrust! In other words, it seems there's a thrust penalty for having your engines angled. I've looked on the forums for info on this and not seen much, but one person suggested the end-thrust is a function of the cosine of the engine angle. My question, I guess, is why. My (probably wrong) understanding was that, if you have two symmetrically balanced engines, as long as there was SOME angle in one direction, they would put full thrust forward regardless of the angle. Those engines' energy has got to go somewhere, and I presume it's not being lost to deformation or heating of the ship in between. If not, the only place the energy could go was forward. The analogy that comes to mind is: squeeze a wet bar of soap between your hands, it will shoot out straight up or in some direction. Not because you pushed it in that specific, but because it's got nowhere else to go when you apply a squeezing force. Can anyone explain what's causing the observed thrust loss? Is there just extra heat generation? Is the specific impulse of the engine affected somehow? Is it just something else? (By the way, if major engine angling is not the answer, I will probably fix my rig by either extending the "tail" so the ship is further in front of the asteroid, or putting the engines out on longer pylons). Thanks for any info you might have!
  23. Is there a mod that lets you collide asteroids to make planets? (I know the "Kopernicus" mod)
  24. I'm building a reusable craft that can capture asteroids in the Dres SOI. I've done this with small (class A & B) asteroids at Kerbin, but never elsewhere. What advice do you have for me about the construction of the craft?
