  1. Val got a bit fed up of Jeb going on about how he'd space-jumped from 70+km and thought she could do better. So she had a word with Bill about building a contraption out of one of his stock of unused flea boosters, re-arranged the universe to provide 120% heating and took it up to 80+km just to shut him up. The results are, I think, definitely more stylish that Jeb's, even if Val read the de-orbit co-ordinates from his post-it by mistake and also had to swim home. https://imgur.com/a/oSuTKX3 ( @Enceos - regarding Jeb's attempt, compare @Chemp 's screen shots with mine - the speed/altitude profile is pretty similar. One key element seems to be keeping the kerbal in retrograde-to-surface both in the EVA pack burn and the the entry into freefall - kerbals have a lot less drag going feet or head first, I've found.)
  2. firda, Sort of - the rotational cancellation in warp is definitely not RL physics. And you are absolutely right in saying there is no absolute FOR and no aether - not even in KSP. But sort of not - it is cancellation of a rotation that would not naturally be there. (And it's a handy cheat to get a spinning or wobbling ship back under control - but that's another thing.) The moon and ISS do rotate in the Earth's FOR. Try this: launch a ship into a stable orbit and turn off SAS. At this point it will be travelling prograde. WITHOUT using warp, wait half an orbit and it will now be travelling retrograde. That's correct by RL physics. If you now apply warp, the ship will continue to behave in the same way, not showing the same side of the ship to the surface. Hence the zeroing of rotation is not correct RL physics, but it is consistent with normal behaviour of orbiting ships in the absence of artificially induced rotation. If you now turn on SAS to point prograde (or retrograde or out or in) then SAS will expend energy rotating the ship to align it with the planet's surface - like the ISS does. Think of the Earth going round the Sun - it rotates 365.25-ish times faster than it orbits. If you could stand on the surface of the Sun with heatproof binoculars, you'd see the Earth spinning frantically as it crossed the sky above you (again relatively speaking timewise). It does not always show one side to the Sun, otherwise there'd be no night and day here. In KSP, planets and moons do maintain their rotation in the FOR of their parent body even in warp, unlike ships. If you need to model something like the behaviour of the ISS even in warp, there's a mod called "PersistentRotation". Here: https://forum.kerbalspaceprogram.com/index.php?/topic/102277-14-persistentrotation-185/ Happy gyrations!
  3. Hi firda. If you mean why does the "bottom" of my spaceship not always point towards the surface of the nearest body, then that's how things behave IRL (at least in Newtonian mechanics, as Freshmeat just said). True, the Moon shows the same face to the Earth (and the Mun is modelled to behave similarly), but that is because it is rotating, just (because of tidal forces) it does this at the precisely same angular velocity that it orbits. More accurately, because the orbit is elliptical, it in fact appears to oscillate - "librate" - slightly as the orbital angular velocity varies with distance. The Mun's orbit IIRC is perfectly circular, so there is zero libration. A spaceship in orbit, once stabilised wrt to some other object, will point in the same direction, as you put it, in some "global" reference frame. But as all things are relative (even in Newtonian Mechanics), there is no such frame - only that of the ship itself. The International Space Station is caused to artificially rotate once per orbit, so that the "downward" and "upward" instruments continue to point at the surface or out into space - but this rotation has to be fine-tuned by thrusters to keep it in synch with its orbital period. See explanation here: https://space.stackexchange.com/questions/12335/why-does-the-iss-rotate-exactly-once-per-orbit/12338?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa Where KSP departs from RL physics is that when you go into warp, any rotation of a ship is zeroed. Hence even if it was spinning it will lose that angular velocity and behave as you describe.
  4. Multiplayer would definitely be a fun thing, but - as has been said many, many times already - adding multiplayer to the game we know and love would be a (lousy) compromise at best. The whole game concept and core code are simply not made that way. Really, despite its oft-aired limitations, I think it has grown into one great open world sim with rockets. Rockets, guys and gals! ROCKETS!! BUT, if a totally new multiplayer-from-the-ground-up game were produced, with the ability to import our Kerbal Kreations and fly/drive/sail/hop them around the Kerbal system together... that could work. If someone (i.e. some company with the rights) were to develop a rich gameplay mechanic for it and crunch the numbers on profitability, accounting for the server infrastructure and storage and privacy concerns, and we - impatient kerballers that we are - could all wait for the dev cycle, and ... ... and above all, figure out who is allowed to be Jeb. (Too late, I called it ).
  5. Here's my attempt. Going for the minimalist, big... er... small time.
  6. The cheat for this is to edit the save file. 1. First, exit from the game. 2. Next, find the save file (for example /saves/Sandbox/persistent.sfs). 3. Make a copy of it in case your triping is as bad as mein. 4. Edit it in notepad (or your favourite text file editor on your OS). 5. Look for the section headed ROSTER, then find your kerbal, like this: ROSTER { ... KERBAL { name = Fred Kerman ... state = Dead 6. Change the state from "Dead" to "Available". 7. Close/Save the file. Note: On older versions of KSP (back before 1.0.5, forget exactly when), the states were represented by numbers: 0 meant Available and 3 meant Dead. Hope this helps. And don't forget to backup that save file!
  7. Either that's an actual bunny-shaped dust bunny, or else the Kraken has transmogrified itself into our universe. (I'll leave it to the reader to work out the significance of the helical threaded fixer.)
  8. And here was me thinking heat was only a problem when it came to fitting enough radiators to a mining base
  9. You're right... I stand corrected.
  10. As you say, if you stick to the (terran) conventional runway numbering then they will all be the same. Some options might be: Come up with a non-standard IDs - in which case, call 'em what you will Red, Green, Blue, anything. Have a more reasoned alternative approach ( ) : I like @Alchemist 's idea. Move them all away from the poles by at least the length of the runway and use the actual azimuth (probably still confusing). Or if you really want a (near) earth-standard numbering, how about... Runways 00C, 00L, 00R and 00X? C being meridian 0 the others 270, 90, 180.
  11. What file extension does it have? But in any case mighty weird if there's no rational explanation for it appearing there. But if it's any consolation at all, there's nothing sinister on the (usual) search engine for the readable text, and the gobbledegook at the bottom is a Googlewhackblat (i.e. one unique hit) pointing to this thread... so there's not a lot of folk out there who have seen this, if it is a result of malware. Do hope its not something nasty.
  12. Here's your hot chocolate fudge cake with extra gravity. I'd like a souped-up flyer, please.
  13. I guess parachutes should be disallowed also?
  14. Sorry... looks like we ran out of one of the ingredients for the Monoprop. I'll have a stable apoapsis served in the Mohole, please.
  15. I saw my first Tesla(s) two years ago on a business trip to Norway. Over there they have big incentives for green technology and electric cars, so lots of plug-in Priuses and some Teslas, especially taxis. Just this weekend I saw a model S in the UK for the first time while visiting south Birmingham. Yet to see one anywhere closer to home.
  16. A work colleague once brought some back from a trip. Ammonia salt! Ugh. I should say, of course, ex-colleague.
  17. Hmmm... from the Kerbals' point of view... Once, many, many years ago, when Kerbals were a simple folk who rarely ventured above ground, a few of the braver souls among them went out of their homes in the black mountains to view the strange little lights that appeared in the sky each day when the big hot light disappeared behind the mountain tops. There was much discussion among kerbalkind as to what these lights might be. On this particular evening, they noticed that one of the small lights was moving rapidly in a way they had not seen before. The light became brighter and brighter, and then came a deep rumbling sound. Some kind of object was falling from the sky trailing red flames. The object approached at frightening speed until it suddenly sprouted some huge mushrooms, whereupon it slowed its descent and floated down to the ground on a large, flat, rectangular area near the big water a few thousand metres from the mountains. One of the kerbals was very excited. He thought that at last they could finally settle the question of what the lights were. So he and a couple of the others that he had persuaded come along set off to see what it was. Three hours of walking through the near darkness (kerbal's big eyes and underground habit meant that there was enough light to see, even by the small lights) brought them to the place. There, on the flat area of land, was a strange metallic object, glinting in the first rays of light from the big light that was about to rise over the sea. The intrepid explorers went to see what this object was. It was whitish, though blackened by the flames. It stood on four flimsy-looking legs, and underneath were some funnel-shaped appendages. Some distance away, the wilted remains of the mushrooms flapped languidly in the morning breeze. On the side of the object was a construction made of struts attached to each other in a series of rectangles. The lead kerbal cautiously ventured over to the object and pulled at the struts. Unexpectedly, they began to move - to expand - and extended themselves down to reach the ground. But before our heroes could flee, a door opened in the side of the object and something - someone? - began to emerge. Yes, it was a kerbal! But a very large kerbal, with long legs - that meant, very impactically, that its arms reached nowhere near the floor - and an oddly spherical head with one huge shiny eye! Fortunately, the large kerbal was emerging backwards and had not apparently seen the open-mouthed trio below. Rooted to the spot with fear and elation, the three investigators watched as the visitor reversed itself down the assembly of struts, backed up a few steps and produced another rod from a pouch in its rather bulky clothing. It then stuck the rod in the ground, from which unfurled a piece of fabric, on which was a design of some sort. The visitor continued to perform some unfathomable tasks, all the while with its back to the wondering kerbals. From time to time it made sounds - very muffled, but one of the three kerbals felt sure it was speech - very strange speech - almost like one of the widely spoken western kerbal dialects, but, but... well, backwards. Then suddenly, the visitor paused. It reached up, and - with a click and a slight hiss - pulled off its own head!! All three kerbals emitted a silent scream of horror. Still unaware of the welcoming committee, the visitor turned and began to place its head carefully down on the grassy surface. To their combined relief, the kerbals realised that the visitor had only doffed a sort of a hat that had been attached to its clothing. But then they saw its real face. Pink. Weird, indistinct pink. With two tiny eyes, a strangely small mouth and above it an ugly lump pierced with two holes. The kerbals screamed again. The visitor suddenly became aware of the intrepid threesome. "Keeeeeeeeeeeeeeeeeee"! It said, in a loud, high-pitched voice, staggering backwards against the sky-object. For what seemed an eternity, no-one breathed. The big hot light had now risen above the sea, and its heat was gaining strength. The alien exhaled deeply, folded its legs and lowered itself to the grass. The kerbals gulped the warm morning air and looked at one another. They began to talk excitedly. The interloper snapped its head up, its hair, gathered in a bunch at the back of its head, swung sharply. "Krot nak ooy!" it said. The kerbals goggled. "file tnejiletni"; this time to itself. "Lbidercni!!". The visitor slowly rose to its feet, and climbed back inside the object. Moments later it reappeared with a bag and a couple of devices that the kerbals could not identify. It began to speak excitedly while pointing one of the devices at the scenery, the kerbals, the sky, the mountains, the object it had arrived in. The kerbals were beginning to feel hungry. It was past breakfast time. Fortunately, one of them had stuffed his pockets with snacks before they set out. He handed some to the others and they nibbled at them. The visitor noticed the snacks and seemed interested. The eldest wondered what these big pink kerbals might eat and gingerly held one out. "ooy knath ho", said the visitor, carefully taking the snack. It held the snack up to its device, then to the protuberance above its mouth. It inhaled sharply. Only after speaking into its other device for some moments, and peering closely at the snack, did the strange visitor cautiously taste the snack. After a couple of tentative licks, it bit off a small corner, chewed and looked pensive. "sisylana erthref rof sith peek erteb" it said, and put the delicious morsel into a pouch. The visitor then went back inside the sky-object and emerged a few minutes later having removed the large bulky clothing it had first been encased in, wearing now lighter and more practical clothing. The kerbals could now see that the alien appeared to be uniformly pinkish and had one too many fingers on each of its hands. Conversation was impossible, but the kerbals felt that there was some kind of rapport in the facial expressions - if the small, ugly, lumpy visage of the visitor could be considered a face. The three kerbals agreed that their strange new friend seemed harmless enough. But what was it doing here, and where did it come from? And most of all - how had it travelled here? They watched the newcomer going about some tasks. Attending to various attachments on the sides of the sky-object. Talking into one of its devices. Pointing its other device at things. Digging up bits of grass, soil and rock and putting them into containers and making marks on the containers with a sort of stick. Down by the edge of the sea, the visitor was collecting more samples. The big light was high overhead now. The kerbals enjoyed the warmth and light. But the alien had begun to change colour. It was now looking distinctly red in places. It pulled out a small bottle and squeezed some goo out onto its odd, hyperdactylous hand. It then proceeded to smear the goo all over its exposed skin. The eldest kerbal had a sudden realisation. He explained to the others - this must be how the big pink kerbals feed themselves. They absorb this alien gloop through their skin! Seeing the kerbals watching, the alien looked up at they big light, back at the trio and offered them the bottle. One of them took it and examined it closely. It had many strange, alien markings on it. "ekyl sith", the visitor said, taking back the bottle. It again squeezed some onto its hand, and, after establishing steady eye contact and smiling broadly, began to gently spread the goo over the kerbal's face, neck and hands. It felt cool and soothing - restful, as if the early evening had come. The kerbal licked the back of his hand. Disgusting!! No wonder they didn't put it in their mouths! The alien went to put the bottle back in a pocket, but the kerbal held out his hands and tried to convey an imploring expression. The visitor frowned, thought for a moment, and handed him the bottle. "ti tnow ooy fi"; "retho-na vah eye". -----
