[01:01:26] why hasnt real solar system been updated? [01:02:04] I dunno, why? [01:02:23] hello where is everyone? [01:02:50] why hasnt rss been updated? [01:04:02] I don't know, what hasn't rss been updated? [01:04:04] well where can i get a 4k milkey way askybox [01:07:19] are you under the effects of alcohol or drugs [01:17:02] Action: JCB ehs...? [01:17:28] Action: Arynnia appears [01:17:29] I see ... life... [01:17:31] heyos [01:21:45] you see more than i do [01:24:15] I seem to think more than I see things... [01:27:04] He's seen things you people wouldn't believe. [01:31:38] one person's mind.. another persons hell [01:31:53] or .... one person's personal hell, perhaps somethign that shouldn't be let out [01:35:54] Speaking of hell, I just beat DoomRL for the first time [01:36:57] lol... rogue-like... not real life [01:37:21] had to look that up.. not often hear about rogue type games these days [01:38:16] er well.. there is a text version as well as pixel top down [01:40:24] It's a fun game [01:43:16] Action: JCB tries to figur eout the XL2 rover wheels a little more [01:54:49] *seeing how fast I can type with a mouse* [01:55:09] Not too bad, actually. [01:55:55] In my opinion, only one good phone game exists. [01:56:12] And it's a roguelike. [01:56:30] Cardinal Quest II. [01:56:47] lol... wow.. can almost hit 120m/s with these giant wheels [01:57:39] The interesting thing about that one is that health is a non-renewable resource. [01:57:50] ok... can I disable collision in the debug menu somehow? [01:58:05] My wrist is getting hecka tired. [01:58:47] Your character does not regain hit points over time. [01:59:25] lol... 6 wheels.. waaay faster. [01:59:41] #KSPOfficial: mode change '+o Supernovy' by ChanServ!ChanServ@services.esper.net [01:59:54] ponder, wonder how this would be as a wheeled launcher.. pulls a good 5gs with traction turned all way up [02:00:25] Spells recharge over time... except for the healing spell, which only recharges as you kill enemies, of which there are finitely many. [02:01:33] lol.. bouncing as crud though.. hmm.. fins [02:03:51] lol... abusing skid steer on these wheels just.. crazy [02:04:19] #KSPOfficial: mode change '+o Supernovy' by ChanServ!ChanServ@services.esper.net [02:04:26] all right... anyone using the ART mod by Roverdude? [02:10:01] My asteroids keeps changing size between reloads :( [02:11:54] Warrigal_, DoomRL only allows healing through consumables, which are non-renewable [02:29:23] ok... I'm at the point where I'm editing my save files... anyone know how I can just move the asteroid further from the craft? [02:33:56] change its position [02:36:21] Arynnia: I was trying to change the grabbing unit's position... [02:36:28] didn't work [02:36:37] I'm now messing with the asteroid itself [02:40:54] worked [02:41:02] back to haversting [03:05:59] what rpg do i do [03:06:02] pokemon or otherwise [03:06:34] mabus: What system(s) do you have? [03:06:46] You could try Chrono Trigger [03:09:41] i beat chrono trigger a couple times [03:09:54] i can play most consoles [03:12:51] mabus: What are you looking for, specifically? [03:14:08] Because I would say: try the 'trails in the sky' series [03:14:35] Or maybe 'I Am Setsuna' [03:14:51] hm havent heard of those [03:15:09] just looking for stat and xp turn based combat [03:15:36] Trails is a recent translation... [03:15:53] And 'I Am Setsuna' is a Switch title [03:17:21] Hey folks. I've been playing with Galileo's Planet Pack - brilliant mod, so nice to have some fresh content - but Ciro looks a bit strange. [03:17:39] mabus: or just chekc Something like https://www.reddit.com/r/JRPG/comments/p3fes/rjrpg_official_recommended_games_list_for_all/ [03:18:03] Anyone seen something like https://imgur.com/a/7vTCQ - is that a scatterer effect that needs tweaking? [03:18:36] That's a bug with -something- that needs tweaking. [03:18:41] I never had that issue with GPP and scatterer\ [03:25:02] #KSPOfficial: mode change '+o Supernovy' by ChanServ!ChanServ@services.esper.net [03:30:37] Found it. I had disabled the Lens Flare Shader troubleshooting something else, and that breaks the .... lens flares. Go figure. :D [03:42:10] JCB: IRC says you pinged me earlier? [04:11:44] oh... [04:12:00] I just posed >ehs...?< [04:12:25] Did you need something? [04:13:19] someone posted if another person was under influence of drugs and alcohol... I was like.. 'the hell..' sorta thing. Sorry, didn't mean confusion [04:15:04] Heh. Okay, no problem. [04:15:22] but since you there.. heyas [04:16:10] Heyas, I suppose. :-P [04:17:26] just have'n some munch with room mates... messing in ksp with some sandbox stuff... [04:18:36] I just finished gorging myself on Christmas dessert. I should go crash some rockets instead; it'd be healthier. [04:22:07] oh.. what was desert? [04:22:32] Apple pie and ice cream, followed by more apple pie and ice cream. [04:22:35] I should probably get around to doing some recordings like I keep telling myself. Just constantly worried about interuptions [04:23:16] ah.. I'd have just gone for hte icecream.. got some myself, plain, though left the bucket at a friend's place [04:27:07] #KSPOfficial: mode change '+o Supernovy' by ChanServ!ChanServ@services.esper.net [06:10:12] why is mars a better spot than the moon for our first permanent extraplanetary base? or is it a toss up [06:10:43] if goal is exploition, space rocks is far better [06:11:00] there is supermetallic rocks that could supply earth for thousand years [06:11:21] also supercarbocous (spelling) with lots water, lighter elements, etc [06:11:47] Rolf: are you talking about Luna or Mars? [06:11:51] the goal is ostensibly a jump off point i guess, and viably being able to be self sustaining [06:11:59] umaxtu: i think hes saying asteroids and whatnot instead [06:12:05] neither. yeah mabus [06:12:08] moon is much much closer, tons easier to send shit to [06:12:29] but if we cant make fuel there its not that great of a jump off point right? [06:12:30] for base dunno, moon is certainly very close. we can easily build tether there [06:12:46] not as much on violites but earth is close [06:12:52] you can make aluminum fuel on the moon [06:12:56] though it's not the best [06:13:02] also H2 mining on the poles [06:13:07] mars has better gravity and lots iron and stuff [06:13:30] iron is useless if it's rust [06:13:38] I think part of it is that humans haven't visited mars yet. [06:13:41] you need proper ore deposits [06:13:41] but needs lot of work to rebuild air, as well as deeper well for jump off point. tether is also still possible with our tech [06:13:49] Kracc: rust - oxygen = iron [06:13:55] we need oxygen also so win win [06:14:10] the dust on mars has a looot more than just rust in it [06:14:21] toxic petrochlorates, silicon, etc etc [06:14:28] yep other issue [06:14:36] moon dust wow its machine killer [06:14:42] plus, the moon has a very similar composition to earth [06:17:16] I wouldn't mind a place on the moon... sort of like having a tree house outside the home back in childhood years [06:17:19] so why would elon musk want to pick mars over moon, something specific to his mission? [06:17:32] elon musk isn't a perfectly rational being [06:17:38] nether is us [06:17:39] as with anything to do with Elon musk... go big or go home.. or just PR stunt [06:17:54] mars window is coming up soon [06:17:58] elon can be a bit nutty, and mars has always been his stated goal [06:17:58] so he just wanna do something [06:18:01] feasibility or not [06:18:28] if I recall he wanna send one of his car to orbit between earth and mars (or venus?) also [06:18:39] musk have big vision but dunno if possible [06:19:57] to be fair, I felt the same way when he first announced they would be vertically landing first stages [06:20:07] his car is already on falcon heavy.. [06:20:19] they just need to stand it up and it'll go zoom.. :\ [06:20:25] personaly, I think its a waste of a car [06:20:36] it's a waste of a rocket [06:20:40] umaxtu: yeah. it was insane. I knew it would be very hard., and he did it [06:21:33] Kracc: only if the launch is a success. If it fails, its just a clever mass simulator [06:22:32] Kracc: oi language [06:22:50] forgot this channel had a G-rating [06:23:32] 9.82 G [06:24:39] eh.. I heard people go nuts over spilled beer... [06:54:54] whats the ksp take on that pentagon ufo guy https://www.nytimes.com/2017/12/16/us/politics/pentagon-program-ufo-harry-reid.html [07:23:45] that's quite an expletive UFO [07:44:16] There's something so odd about that program [07:44:27] Mostly that the money goes to Bigelow in a way [07:44:31] And he's crazy [07:46:34] what program? [07:46:48] https://www.nytimes.com/2017/12/16/us/politics/pentagon-program-ufo-harry-reid.html [07:51:18] wake up, sheeple [07:51:24] the end of times is near [07:51:27] WAKE UP, SHEEPLE [07:51:38] only sheeple can defend us from aliens! [07:53:48] bees: https://imgs.xkcd.com/comics/wake_up_sheeple.png [07:54:39] https://imgs.xkcd.com/comics/sheeple.png also works well [07:59:39] Ever since the advent of cell phone cameras, alien sightings have gone down. [07:59:47] funny.

What are you doing with magnets [10:02:57] hanging things to the frame of my desk mostly [11:37:12] https://78.media.tumblr.com/8ea5743f2cd1f0ad0bc96eebc84ed080/tumblr_mhmn3zh76O1qgu2wio1_540.jpg [11:40:42] strange bird [11:40:59] he big boi [11:47:52] I still have the photo of the fox hanging out with his sheep buddies [12:00:26] https://78.media.tumblr.com/2e43aa887105a39e2d02f66975941594/tumblr_p074c4ppFb1qg9yhjo1_540.jpg [12:04:32] old [12:04:43] this happened weeks ago [12:04:47] good [12:47:53] I'm not sure how they figure that Mars has been observed to be round. [12:48:40] I'm still laughing at that guy planning to send a rocket up to less than 1km and is powering it off some absurd method. [12:48:50] When we have planes that get to 4km with no issues. [12:49:10] pretty usual to fly at 10 km [12:49:13] I'm talking Cessna 172 has a higher altitude than his rocket. [12:49:20] just buy an airplane ticket lol [12:49:24] yeah [12:49:29] $80 [12:49:55] So he's building a rocket in his back yard with a 40 degree launch angle because I guess he can't do math. [12:50:20] url? [12:50:25] He's going for altitude, but going sideways, and going lower than cheap single engine propeller planes. [12:50:45] No idea. I forget what it was. He's a flat earther and doesn't believe in math or science. [12:51:31] >Latest Rocket Test Crash With the firmament Dome Over the Flat earth [12:51:32] what [12:52:00] https://www.washingtonpost.com/news/speaking-of-science/wp/2017/11/21/this-man-is-about-to-launch-himself-in-his-homemade-rocket-to-prove-the-earth-is-flat/ I guess this is it. [12:52:07] Nobody else makes a rocket to go up less than 1km [12:52:09] sounds just like him [12:52:24] hehe [12:52:31] at least use a balloon [12:52:37] I know. [12:52:47] Even freaking hot air balloons can outperform this thing. [12:52:54] I don't get the point. [12:55:22] come on. a flat earther. everything is a lie. so has to use the methods they say are the least effective [12:56:51] think he just wants to go 1km because too worried, might break his beliefs? [12:57:03] Well, he might break his neck... [12:57:21] I hope not, he might become some kind of martyr [12:57:23] 200m should be more than enough to disprove a flat earth [12:58:17] mind you, a level with sights is needed [12:58:24] oh wait.. steam powered rocket huh? [12:58:27] (I've yet to test it out) [12:58:34] Yeah [12:58:39] got everything I need, though [12:58:44] I can sea the earth curvature witht he camera of my rc plane [12:58:49] Not sure why steam instead of compressed air or .... maybe literally using rocket fuel? [12:58:52] but it's a wide angle lens so it doesn't count I guess [12:58:53] hmm.. anyone else done steam powered rockets and gotten 1km up? [12:59:13] How terrible is Stem as a propellant? [12:59:17] I can see why steam, not air... water vapour carries more mass [12:59:19] I'd expect pretty freaking bad. [12:59:22] (the theory is that the horizon drops perceptibly with simple tools even at 200m) [12:59:31] Then use a compressed air water rocket. [12:59:39] steam rocket lol [12:59:45] Then climb a freaking mountain. [12:59:45] I see guys do water bottle rockets [12:59:51] you can prove earth curvature with a camera drone [12:59:52] You can already get 3km up easily. [12:59:53] JCB: actually, water vapor carries /less/ mass [12:59:55] at sunset [13:00:05] compressed air, pushes mass of water out a nozzle, its pretty effective [13:00:08] or accidentally as is did with a plane ticket again [13:00:14] only 18g/mole instead of 28(N2) or 32(O2) [13:00:24] At what pressure? [13:00:41] I don't know how he's planning to flash boil this, either. [13:00:51] uranium [13:00:53] probably already turned to steam [13:01:05] But it's going to cool down super quickly. [13:01:10] probably wind up with a steamed flatearther [13:01:21] if air carries more.. why not just air powered trains? [13:01:22] FAA is having none of it. [13:01:32] JCB: because you want less [13:01:46] lower mass allows for higher Isp [13:02:13] all depends... [13:02:23] water > steam creates a very very large volume of expansion and it is accomplished by applying heat, which is very easy to do. [13:02:39] for the same chamber temperature, lower molecular mass will give higher Isp [13:02:43] same thrust, though [13:03:22] My main issue with this is it's all done easier and better by other methods. [13:04:02] korsene vs cyrogenics... each has ups and downs. [13:04:13] And then we can probably convince him that the government has him stuck in the matrix when he went to sleep one night. [13:04:14] https://en.wikipedia.org/wiki/Rocket_engine#Propellant_efficiency [13:04:40] while one works better, it has down sides as well [13:05:07] The Mythbusters air powered boat was pretty funny. [13:05:17] It was like farting in a bathtub. [13:05:24] About as effective at moving it. [13:05:52] Though I didn't expect the loose air tank to be as destructive as it was. [13:07:02] eh well.. if they maybe used the compressed air to run a prop.. may have been more effective [13:07:24] That's what I was thinking about. [13:07:34] not so much what spits out the back, its how you use that power [13:08:06] high bypass jet engines, even turbo props sorta work the same way... [13:08:29] you have your engine, producing hte power, while it spits high power out the back, its actually the big fan on the front that does most of hte owrk. [13:08:49] ... does most of the work. ugh.. this holiday is messing with me a little.

[13:32:13] ugh... sad ksp can't handle the wheel physics on tail drager type planes too well [13:33:11] wheels are hard [13:33:20] but what is the problem? [13:36:07] Fluburtur: f-104 [13:36:24] Fluburtur: one of the weird f-104 derivatives [13:38:11] heh I did a f-104 in game as well... well two versions. just different noses [13:38:52] oh just... can't have main landing gear forwards of CoM else, plane wants to keep wind vaneing 180 [13:39:43] has to be nearly right under CoM. then there is near constant 'drifting', skidding around like you were on ice [13:40:08] but anyways... [13:44:01] https://i.imgur.com/nFQfCb3.jpg [17:43:53] Decided this game is no reverts. Hopefully I'll only waste money and not time.

[17:51:53] yeah [17:52:22] Sounds like a good addon for Chatterer [17:52:24] kind of like in Simcopter or Cities: skylines [17:53:14] 5=8B! https://youtu.be/dLWsqQs8Iys [17:53:14] YouTube - @O<0O B@0=A;OF8O 70?CA:0  "5=8B-2S" A  "=3>A0B" [17:53:15] it's one of the features I like in Fallout 3 and NV [17:54:26] Now I'm wondering what the KSP equivalent of jingle jangle jingle would be [17:57:04] what is this [17:57:31] angosat [17:57:44] https://www.youtube.com/watch?v=VceeDm5MSt4 [17:57:44] YouTube - Fallout New Vegas Soundtrack - (I've Got Spurs That) Jingle Jangle Jingle [17:59:55] Mathuin: https://www.nexusmods.com/fallout3/mods/14946/? , https://www.nexusmods.com/newvegas/mods/40453/? and https://www.nexusmods.com/fallout4/mods/637/?

[18:09:22] Johnny Guitar [18:14:20] sup [18:17:19] meh [18:18:28] I'm watching a slowly rotating PotatoRoid, trying to find a good spot to grab [18:23:11] dammit... [18:23:21] I might have to get rid of USI ART [18:25:28] I quicksave before grabbing the asteroid... and when I reload it's a different, smaller, asteroid [18:26:17] lol nice [18:26:44] I've been having a bitch of a time setting up asteroid missions lately, seemed like it wasn't nearly as painful last time I tried doing it [18:26:52] err language, sorry [18:27:09] been on discord too much [18:27:28] ART makes asteroids bigger... but it's buggy for me :/ [18:27:52] The mass and name stays, but the asteroids changes between size between reloads [18:28:13] yeah, I have had issues with other mods similar to that [18:28:33] like I really like the SEP mod, but at least on my system, whenever I change scenes away, the calibration on the experiments gets reset [18:28:55] It's more annying when you ship loads inside a bigger asteroid... [18:28:59] so I could have an experiment set to 175% calibration with a 17d duration, go to space center and come back [18:29:07] #KSPOfficial: mode change '+o APlayer' by ChanServ!ChanServ@services.esper.net [18:29:07] and then it'll be reset to 50% calibration and 75d duration [18:30:09] I don't mind if they stay bog or small, I can still excavate the inside and re-use it... [18:30:39] ...but make up your mind! Stay big or stay small! No magic resize [18:31:16] I'm thinking about getting the Mk4 spaceplane parts and manually adding some of the OPT wings tonight [18:31:26] I don't want to do full OPT because I think it's super OP [18:31:42] but I need a spaceplane that can carry 3.75m cargo [18:33:17] Hi there! Merry X-Mas and sorry for not having joined the party here! [18:33:23] I also jumped down the kOS rabbithole finally over the break [18:33:48] have already automated take off, ascent, and circularization for my spaceplanes [18:34:03] I got the Mario+rabbids game... so I'm going down THAT rabbids hole [18:34:03] I think it'll be a while before I can figure out how to autopilot landing though heh [18:34:26] I got my family a Switch for Christmas, we've been playing MK8 :) [18:35:04] WOAH! I got a 325000 tonnes asteroid... [18:35:15] no wonder I could not rotate [18:35:15] lol [18:35:36] my spaceplane ascents are so much more reliable now that I don't have to worry about the twitchy controls throwing me off heading [18:36:02] madmerlyn: Automate rockets. :P [18:36:07] I even wrote my script so it defaults to a 80km orbit, but when I call it I can specific my desired orbit as a parameter [18:36:41] well before I got started on the planes I spent an entire night working out orbit, payload dump, deorbit and land on the launchpad [18:36:48] madmerlyn: I boot with a default script at around 80km [18:36:50] quit after my first successful pad landing [18:37:02] What algorithm do you use for achieving orbit, though? [18:37:08] ^ [18:37:29] just a manual pitch adjustment [18:37:46] it became an obsession of mine to try to minimize dV [18:37:50] drops the pitch by 0.2 every 0.2 seconds until it hits 1 after 120m/s [18:38:02] I don't have a perfect rocket script yet heh [18:38:05] I soon learned that it's not trivial [18:38:15] problem I had when I finally landed on the pad though [18:38:38] was my rocket was big.. really big, for a 20t payload, and the cost per ton for the fuel when it was all said and done was over 3k [18:38:50] ve2dmn: Rocket science is not trivial, yes [18:38:51] :P [18:38:57] I can put a 55t payload in orbit on my planes for between 500 and 650 per ton [18:39:28] especially now that I've automated their ascents [18:39:43] automating the landing is going to be a big challenge though heh [18:39:49] I never managed to master the art of Spaceplane design [18:39:51] I've actually gotten really good at landing manually though [18:40:14] I either lose control of the plane, or lack enough TWR to make it into orbit [18:40:18] what do you mean by automated ascent? plane flies itself or you have a script flying it? [18:40:27] kOS [18:40:31] Black_Eagle: kOS [18:40:45] what's that? [18:41:21] I open kOS put `run gallahad.ks(100000).` and the plane will end up in a 100km orbit + or - 1km or so [18:41:22] https://ksp-kos.github.io/KOS/ [18:41:59] "kOS is an autopilot you script yourself. kOS is to programming, what Kerbal Space Program itself is to rocket science. You dont have to know what youre doing to get started, but you may find yourself learning a lot by accident as you play with it." [18:42:16] I like doing it with kOS a lot better than using something like MechJeb because I *wrote* it myself and didn't just download and punch numbers in [18:42:36] There is also kRPC if you prefer Python [18:42:47] so it's a script [18:42:48] I mean have to do that, I do prefer Python :P [18:42:52] might* [18:43:05] also I'm planning on building my own custom controller at some point as well [18:43:11] 17 minutes [18:43:15] is kRPC up to 1.3.1 yet though? [18:43:24] 17 minutes to what Althego? [18:43:30] until launch [18:43:39] just trying to remind mysel [18:43:40] I know it's not a SpaceX launch, I already watched the final launch of the year :P [18:44:56] yes Black_eagle it's a script that I wrote for my planes [18:45:09] Nice... the asteroid is so massive that I can only get 1m/s of dV with 8400 Liquid fuel [18:45:12] you have to put a kOS part on your plane, they have different memory sizes etc. [18:45:20] and then you tell it to run the script and away it goes [18:46:04] ve2dmn word on the street is the beta version of USI Constellation brought back planetary logistics [18:46:15] err orbital logistics I mean [18:46:37] as in surface to orbit, hopefully it only does it on planets that have reached the appropriate level of kolonization though [18:47:07] ve2dmn: Screenshots? [18:47:26] another neat thing I want to develop for my spaceplanes though is a kOS script with independent programmatic thrust control for VTOL [18:47:50] have it manually adjust thrust on individual VTOL engines to maintain pitch+altitude [18:48:08] APlayer: http://steamcommunity.com/broadcast/watch/76561197994451548/ [18:48:26] I had to stop using steam for my KSP, it was crashing it regularly [18:49:19] here are my planes etc. on KerbalX, most of them I've updated for 1.3.1, and the Gallahad I've expanded into an entire class of planes instead of just 1 https://kerbalx.com/madmerlyn/ [18:50:21] regular Gallahad can put 55t in 80km orbit, the L can do 18t to high orbit or about 26t to 80km [18:50:38] LC has same capabilities as the L roughly but with a crew configuration [18:50:43] I don't think I'm gonna be able to diverte that asteroid before it hits Kerbin [18:51:17] still working the bugs out of Lancelot Mk2 before I upload to KerbalX [18:51:31] I added a second optional parameter to my orbit kOS script for the Lancelot mk2 [18:51:57] the landing gear is too far back to properly lift the nose on the runway during takeoff, but I don't want to move the gear forward for fear of tailstrikes when landing [18:52:11] ve2dmn: Ion engines... Ion engines are your friend. [18:52:21] so I added "nosekicker" engines to the front of the plane, separatrons, that my script fires off when it's ready to nose up [18:52:27] APlayer: not enough TWR [18:52:37] Of course enough TWR [18:52:44] Also, they aren't unlocked yet [18:52:45] lol ion engines on a 325kton asteroid [18:53:33] Use clusters when in doubt, if the maneuver takes less than 12 hours in real time you're good to go [18:53:42] 20m/s burn, estimated burn time NaN [18:54:06] madmerlyn: right now? 33m/s. Estimated time 2d 4h [18:54:10] IIRC the stock engine provides 3.6 kN of thrust? [18:54:16] 2kN [18:54:20] What's the ISP? [18:54:26] over 9000 [18:54:48] Uh, 9000 indeed? [18:55:05] specific impulse is irrelevant to burn time for deltaV though, it only affects how long you can light the engines before you run out of fuel [18:55:28] big with asteroids, you make your own fuel [18:55:30] 4200 s [18:55:40] if you're trying to push around 325000 tons with ions, your burn times, even with a VERY large cluster are going to be unrealistically long [18:55:49] madmerlyn: It is directly relevant, as the amount of fuel you need to carry depends on it [18:56:17] right but that's not a factor on burn time for a 20m/s burn though [18:56:24] we're just talking about raw TWR here [18:56:44] even a gamebreaking large cluster of ions isn't going to provide a useful TWR on 325 kilotons [18:58:08] tweakscale / modded ions? [18:59:20] unrealistic IMO [18:59:26] what happened to the countdown? [18:59:53] ¯\_(Ä)_/¯ [19:00:32] hmm it started [19:00:33] launch! [19:01:04] yellog-blue flames [19:01:29] did I miss a launch again? [19:01:38] i miss the liftoff too [19:01:42] because they removed the timer [19:01:46] you guys don't post rocket launches enough [19:01:49] who's the launch? [19:01:56] wut up flub! [19:02:03] yo mad [19:02:31] OK, math says you need ~260.5 tons of Xenon for the maneuver [19:02:36] after exploring the KSP discord for a while, I've decided the average age there was too low for me to enjoy it long term heh so I have returned to IRC [19:02:40] AT 4200 s ISP [19:02:43] madmerlyn: 5=8B 3¦ with an Angolan comm sat [19:02:56] is that russian? lol [19:03:08] madmerlyn: they are too young, or are we too old? [19:03:18] Well, more Ukrainian [19:03:30] I'm pretty sure the average user age on the KSP discord is early teens [19:03:50] not that there's anything wrong with teens, but in large numbers they seem to be less intellectual lol [19:03:55] First stage is powered by the famous RD-171 [19:04:26] UmbralRaptor: and the math is fuel by coffee [19:04:28] X-mas Eve I had to strain my eyes on probably 500 images posted by one guy who *REALLY* liked the durtylens filter on K3P [19:04:47] Alright, I stand corrected [19:04:53] ve2dmn: Yay, coffee. [19:05:20] You'd need 212,898,376.125468545033712658592 ion engines for the maneuver to take 12 hours, assuming engines are massless [19:05:26] lol [19:05:51] Hah! [19:05:55] or tweakscale 1 engine to 213 million times its original size [19:06:02] lol [19:06:07] That's no moon! [19:06:53] madmerlyn: IIRC thrust depends on the volume, i.e. quberoot(213,000,000) the original size [19:07:00] cuberoot* [19:07:09] let's hope this time there is no amateur mistake again. like probe not deploying and things like that :) [19:07:14] Action: APlayer howls at his own spelling sometimes [19:07:18] #heDidTheMath [19:07:45] Umbral, Althego: What are you guys talking about? [19:07:52] ok so it'd only have to be 3.8M times as large? [19:08:06] still would be in the "That's no moon" territory :P [19:08:08] APlayer: moving an asteroid [19:08:22] Also the 5=8B launch [19:08:50] "5=8B 3¦ with an Angolan comm sat"? [19:09:15] Yeah, that was what I was wondering about. Did I miss something? [19:09:21] Let's see if this frigate works. [19:09:25] btw, who was ultimatly held responsible for the iridium 33 collision? [19:09:39] wait there was an iridium collision? [19:09:45] APlayer: the launch, I guess. [19:09:47] yeas ago [19:09:54] years* [19:10:14] madmerlyn: https://en.wikipedia.org/wiki/2009_satellite_collision [19:10:46] I watched the Iridium 4 or whatever launch from SpaceX last week [19:10:48] stream offline [19:10:56] mothership. drives offline [19:11:31] the new "bonus payload" they stuck on those sats is going to be interesting, very big brother-ish, but should make it so Malaysian Airlines can't lose any more planes without us knowing exactly when they went off the grid [19:12:26] madmerlyn: you can see the cloud of debri on stuffin.space [19:12:30] That article has some amazing images: https://upload.wikimedia.org/wikipedia/commons/6/6d/Hypervelocity_Impact.png [19:16:29] on the subject of eliminating space junk, what if someone launched a suborbital vessel with a "scoop" that grabbed teh defunct sat/etc. or would that require some exotic/fictional materials like adamantium to survive teh high relative velocity [19:17:04] madmerlyn: Regarding the impact, see the image I sent [19:17:22] This is pretty much what happens during such a collision [19:17:54] It would probably create a bunch of small pieces of debris for every large one it caught this way [19:17:59] right but a suborbital launch could be done to reduce relative velocity [19:18:06] If it survived, that is [19:18:22] yeah suborbital trash gators probably not a great idea heh [19:18:25] Uh, orbital velocity is about 8.5 km/s [19:18:28] LEO [19:19:23] If you launched sub-orbital you would have impacts at about 8.5 km/s velocity, if you tried to match orbits it would be less [19:19:48] Hence all concepts try to rendezvous with the debris before capturing it [19:20:12] launch 100x100x100 cube of aerogel /s [19:20:48] lol suborbital ballistic dummies [19:22:31] Considering the collion in 2009 was 11.70 km/s, I don't think you can design something to survive such an impact without losing 'something' [19:23:05] hehe [19:23:26] okay 100x100x100 could be a little bit too big for rockets [19:23:32] so you make the aerogel contain a caustic agent that turns anything that hits it into gaseous matter instead :P [19:23:55] launch 40x40x40 cube of aerogel and let it soak debris? [19:24:08] and hope the acid clouds dissipate before you launch something useful in the vicinity [19:24:18] bees: you'll get tons of aerogel debris instead [19:24:40] plane-based lasers it is [19:24:44] ve2dmn: https://en.wikipedia.org/wiki/Stardust_(spacecraft)#Sample_collection [19:25:00] "set phasers to clean." [19:25:08] maybe it could work! [19:25:12] bees: that requires matching velocity [19:25:30] see http://stuffin.space/ [19:25:33] for some reason i think that aerogel debris would be harmless [19:25:43] too small [19:25:45] Weighs nothing indeed [19:25:55] But is still fast as a lot of bees [19:26:00] (No, not really) [19:27:21] Hmm. Flying craft via kOS without reverts is .. exciting. [19:27:38] you need to run "simulations" before you do it without reverts heh [19:27:47] Mathuin: I can relate [19:28:01] Hence I test my code extensively before using it :P [19:28:03] I am now picturing Gene Kerman filing half a dozen bug reports against the repository. "Forgot to point prograde before initiating circularization." "Forgot to make initial turn in gravity turn script." [19:28:19] Executive at Lockheed Martin: "What if we just took our 300 million dollar spacecraft and tried our new code on it without simulation first?" [19:28:27] On the bright side, I got a $9k vessel to 3.0 Mm. [19:28:40] 'git blame'.... "JEB!!!!!!" [19:29:17] "Issue #1337: Rocket points the wrong way" - Gene Kerman, 2017 [19:29:40] "What I expected: to go to space today." [19:30:07] Mathuin: what happened: Borken launchpad [19:30:43] Someone please make this meme space styled: https://i.imgur.com/fTYAr8a.jpg [19:31:20] really old [19:31:28] may be older than the internet [19:32:05] I still need an aerospace themed version of this [19:32:14] Might attempt it one day, but I need pics [19:32:27] APlayer I can do a KSP one tonight :P [19:32:41] We need one, yep :D [19:39:46] It also looks like I have quite a wait for this thing to land, so I can write the rest of the gravity turn script (what to do at intermediate altitude -- maintain apo time at 45 seconds, now to figure out *how*). [19:42:33] Mathuin: I'd suggest at intermediate altitude you should plot a ballistic trajectory toward the landing site and try to maintain the location of impact on the runway [19:42:43] Using lift, that is [19:43:11] This is for entering orbit [19:43:13] Not returning. [19:43:16] Ah [19:43:17] Returning is .. ambitious. :-) [19:43:39] #KSPOfficial: mode change '+o NBones' by ChanServ!ChanServ@services.esper.net [19:43:46] Maintaining apo at a certain distance sounds like a job for PID loops [19:43:49] #KSPOfficial: mode change '+o DuoDex' by ChanServ!ChanServ@services.esper.net [19:45:17] Mathuin: Why is it ambitious, though? [19:45:43] Most of Canada is under a Cold weather advisory... yet since the Quebec-Windsor corridor and BC is clear, that means that it's only about 20-30% of the population [19:45:44] Returning in a specific location at this point exceeds my abilities. [19:46:38] Warp till opposite of KSC on your orbit, lower PE to perhaps 30 or 40 km, warp till atmo, shed velocity, maintain impact location at KSC, land [19:46:47] And expressing all that in kOS is hard. [19:47:14] so I haven't played KSP in a long while, what mods should I use? [19:47:19] Landing itself is the hardest part as I see it, but it's doable, I guess [19:47:36] GunqqerFriithian: Depends on what direction you want to go in [19:47:48] fun play, not too grindy [19:48:03] I like a touch of realism, so I can recommend you some stuff there without an outright RO install [19:48:06] #KSPOfficial: mode change '+o UmbralRaptor' by ChanServ!ChanServ@services.esper.net [19:48:11] RO is for the hardcore guys [19:48:25] yeah im not that hardcore [19:49:57] So, I use a larger system (KScale64 is a good start) which makes LKO pics look like LKO and not HKO. To rebalance the game for that, I use part mods like SpaceY, it integrates well with stock [19:50:25] GunqqerFriithian: KER, "[x] science", Chatterre, Docking port alignement idicator, KAC, Portrait Stats, Station science, Trajectories, Scansat, KEI [19:50:45] KEI is easy mode for gathering Science around the KSC [19:50:46] Then, I really like the mechanics of Kerbalism, it adds a lot of exploration aspects to the game. Neat Future Technologies goes nicely as a parts pack with that [19:50:47] CKAN works on linux with mono, right? [19:50:53] yes [19:51:08] Near Future Technologies* [19:52:21] For manned exploration I use KBPS (amazing surface hab/base parts pack) and Kerbetrotter (manned rover parts pack). Both are from the same maker and IMHO the best mods in terms of stock/mod integration [19:53:05] For game QoL, I mainly use KER, Trajectories, Launch Window Planner, FMRS [19:53:35] SCANsat, KIS, KAS and SEP are nice gameplay additions [19:53:58] Thanks for all the sugetions, time to go through them and see exactly what they are :P [19:54:01] I guess that was the main stuff [19:54:19] Feel free to ask about the mods, I'll gladly provide the info I know [19:57:33] I don't like using KBPS parts on actual spacecraft though, I feel like they're a little too powerful for use outside of a planetary body [19:58:28] They look weird when in space [19:59:06] like the greenhouse, I like to think when it's on the surface of the moon, they can use the the surface underneath the module to accommodate growing food in soil etc. But when someone clips one into an interplanetary vessel I feel like they're just trying to save mass by using the KPBS part over a designed-for-space agroponics unit [19:59:45] that said I haven't used any KPBS structures in my current career, really need to [20:00:05] this career has been a big one for me though, I've visited every planet except Eeloo already and it's not even Y3 yet [20:00:25] Still aiming to make a The Martian-styled Duna mission in this Sandbox save, pretty much dedicating all my KSP time to it [20:00:59] OH, if I were at home I'd have some screenshots to share with you APlayer, I'm doing a Lockheed Martin style mission to Duna [20:01:22] my base-camp doesn't look much like the LM Base Camp though due to all the needed USI parts for life support heh [20:01:40] but my landing and ascent vehicle looks pretty close to the LM concept [20:01:49] I even did such a mission before, but did not document it. Then I attempted it a second time with improvements, but it did not quite work out as planned and I eventually abandoned it due to time issues [20:02:17] well for my big Base Camp vessel I'm actually going to build a dry-dock in Kerbin orbit [20:02:18] And what I am doing now looks like it will be a monstrosity [20:02:43] since I like launching everything on planes now drydock seemed like a good idea [20:02:51] I already spent months on it and only just created the landing script for a Falcon 9 like launcher, which is the very beginning of the mission planning [20:03:28] if I can make my vessels more accurate at the landing approach so they don't need to hover I think I could make my launch vehicles small enough that the cost per ton would be worth it [20:03:38] but it's a hard sell when I already have fantastic cost per ton with the planes [20:04:11] So yeah, I guess I am taking it a bit too seriously, but I want to make this /the/ perfect KSP mission to Duna [20:04:26] With a cinematic trailer as the end product [20:05:10] There needs to be a *LOT* more examples of this PID loop stuff. [20:05:29] course I could settle for the 2% launcher cost loss by just landing my first stage *near* the KSC instead of on the pad [20:05:52] Mathuin: A second [20:05:59] the script I have for landing now is accurate enough that I can land even inside the boundary of the launchpad's biome (like next to the flagpole) pretty reliably. [20:06:28] but the hovering is killing me, takes so much fuel to hover around [20:06:39] Mathuin: OK, so what is it that you are struggling with? [20:06:39] which is why I have a 5m stack to put 20t in orbit and return >.> [20:07:45] madmerlyn: Why hover, even? [20:07:48] madmerlyn, how long does it spend hovering? [20:08:33] well I was trying to land directly on the launchpad, and often I'd be skewed north or south of the pad instead of east or west so my hover would pull me back north or south [20:09:02] but the 1 success I had landing on the pad the fuel cost was over 3k per ton [20:09:03] Don't hover, just point in the direction of the launch pad while suicide burning [20:09:21] Also consider landing in the ocean [20:09:25] of payload that is, 3k per ton of payload [20:09:28] Also, pics? :D [20:09:40] I dunno if I put any on imgur, lemme look [20:10:23] nah I don't have any hover pics on imgur, just a bunch from a stupid challenge I did on the discord (challenges were really stupid there, not neat like the reddit ones) [20:11:15] 80 kerbs + 40 sats in orbit of Mun in 1 launch? ok so build a big "moar boosters" rocket to land a bunch of mk3 cabins and use junk cubesat relays, wasn't hard at all, just a big ugly rocket [20:11:18] APlayer: I have no idea how to select constants. [20:11:27] Ah, there we go [20:11:38] Mathuin: So, this is a whole art on its own [20:11:53] I mean this wasn't challenging, and it definitely wasn't fun heh: https://i.imgur.com/6ufsscz.png [20:12:21] I have maximum and minimum settings for throttle, I have a target value (ETA to apoapsis), and I want to increase throttle when the ETA is over my target time, and decrease it when it's lower. [20:12:24] There is a bunch of tuning methods, but really, the best way is to understand what the constants do, and using this understanding and your gut feeling tune them [20:13:01] I think I'm going to have to do PID loops to make my autopilot land on the runway [20:13:11] I also know how to set the throttle. I *don't* know any of this for heading. :-( [20:13:13] So, for the first part [20:13:24] Understanding what the constants do [20:13:26] trajectories makes it pretty easy to aim in kOS, but landing you gotta line up beforehand or it goes nutty [20:14:27] Mathuin: The KP constant is basically the workhorse of the whole PID loop. You need to tune it in such a way that it outputs about maximum output at the maximum error [20:14:39] time to re-read https://forum.kerbalspaceprogram.com/index.php?/topic/45015-the-art-of-modular-base-building/ [20:14:45] my typical approach I come in around 45 degrees, gradually sloping down to 35 degrees until I get down to 300m/s or so, then I point my nose down and come down to low altitude and make a shallow descent to the runway [20:14:45] Just eyeball the normal conditions and set it to a reasonable number in this sense [20:15:09] I do not know the normal conditions, nor do I know what is a reasonable number. [20:16:01] The pidloop tutorial in the kOS documentation shows a setpoint and a proportional gain. [20:16:06] Mathuin: The KI constant is the second "workhorse" of the loop. It kicks in when your error changes in such a way that you have a steady state error, that is the error and the KP parts fight each other in such a way that the error does not change [20:16:28] KP is the proportional gain, the setpoint is what your input should be [20:16:35] another thing I'm not sure if I need to address with kOS or if I can even do, is I often push some fuel around until I feel like I have good control of my attitude once I'm in the plasma on re-entry [20:16:35] The error is the difference [20:16:58] The setpoint is what the *input* should be, or the output? [20:16:59] APlayer: that's a good TL;DR [20:17:09] Mathuin: The input [20:17:21] course if I completely automate take off and landing I could eliminate excess fuel and just design the plane to be balanced when it's empty [20:17:34] The input is your process variable, and you want to get it close to the setpoint [20:17:43] The PID loop tries to do exactly that [20:17:57] my Gallahad series planes can land without firing the engines post-re-entry at all pretty reliably [20:18:03] Okay, to make sure I've got the right ends in the right place, is the input the time to apoapsis or is the input the throttle setting? [20:18:15] The time to apoapsis [20:18:23] And the setpoint is 45 seconds [20:18:29] Okay! [20:18:36] That helps a lot. [20:18:42] The output is the throttle, since that is what the loop controls [20:19:03] Now, you need to tune KP, KI and KD [20:19:12] ... no, we never talked about Kd [20:19:24] As I said, try launching by hand and see whats a reasonable maximum error [20:20:16] Then see what your maximum output is, in this case 1 (as the throttle goes from 0 to 1) [20:20:44] Now make sure KP * maxError = approx. 1 [20:21:09] That is, KP should be such that the maximum error yields a maximum output [20:21:27] Next, have a look at KI [20:21:56] How do you quantify maximum error? [20:22:30] During a reasonable launch by hand, what is the lowest your time to apo is? [20:22:31] APlayer here's a pic for you, my accurate recreation of the N1 https://media.discordapp.net/attachments/377130428991012864/393928432586588160/unknown.png [20:22:43] I have no reasonable or typical values at this time, I just built this thing. [20:23:02] It reaches three million meters when misconfigured. :-) [20:23:06] [that was actually one of my failed attempts to land on the pad] [20:23:29] Launch it by hand a few times, your gut feeling is a really good algorithm to get initial data [20:24:22] Just think about it this way: "How low should the time to apoapsis be for me to go full throttle in order to make it larger?" [20:24:34] How does this account for headings? [20:24:39] Not at all [20:25:11] PID loops don't do this easily, you'd have to post-process the output in order to account for headings [20:25:34] So I'm locking the heading to prograde for the moment. [20:25:44] Yep [20:26:12] Anyway, as I said, launch a few times by hand and ask yourself that question I posted [20:26:31] I will give it a try. It's an expensive proposition without reverting. [20:26:33] Then you get a maximum error, or a reasonable guess for one [20:26:44] Feel free to revert [20:26:57] Tuning PID loops would be done in a simulation anyway [20:27:07] another fun thing with my Gallahad, a redditor actually helped me convert it from a 2STO to a SSTO [20:27:26] by simply removing some fuel, heh [20:27:27] So, assuming you get the KP constant to a good number, let's move on to KI [20:27:42] Actually, I'd rather go on with KD first, even [20:28:12] The docs move to the integral term, in order to stabilize the loop if I understand what I'm reading. [20:28:18] So, KD is what prevents KP and KI from overdoing it and overshooting the setpoint, that is it makes them stop in time [20:28:33] Nah, do KD first [20:29:55] I'm now trying the proportional value [20:30:00] KD achieves this by taking the change of the input per time (the derivative of the input), and adding that to the whole term [20:31:12] So, have another look at how your rocket behaves with only KP. The moment it overshoots the target 45 seconds, what's the rate of change? At about this rate of change, the KD term should be at its maximum, that is 1 again [20:31:26] How would you measure the rate of change? [20:31:54] Print the difference between the current time to apo and the last iteration's time to apo, divided by the time [20:32:07] By the time since the last iteration, that is [20:32:15] That's the D term in this loop. [20:32:20] Yeah [20:32:49] So, make sure KD * D reaches 1 at the maximum rate of change, which occurs at the moment of overshoot [20:33:33] This should get you a solid PD loop that gets you reasonably close to your setpoint with reasonably stability [20:34:16] First pass with the P loop shows me that my rocket is not very stable. [20:34:47] Finally, the last touch is KI, which makes sure you have no "deadlock" between a changing error and your KP term. It constantly increases as your error persists, and thus forces the output to counteract it [20:34:52] But the engines cut out at the intermediate altitude, which had an ETA >45s [20:35:44] You should have a look at how your integral term behaves and make KI * I equal to 1 at maximum I [20:35:45] I need to put some wheels on the next one of these. [20:36:07] ok this is kinda cool https://kerbalx.com/Sunfire/Deep-Space-Nine-2017DS9 [20:36:42] Then repeat the KD step, because KI messes this part up (it causes lagging oscillations, because the KI roughly enhances the KP term as well) [20:36:54] The rockets don't start until like 16 seconds, I wonder why [20:36:57] Then you should have a more or less okay loop [20:37:02] 45-16 = 30, which is a large amount. [20:37:31] ve2dmn, correct me if I seriously mess things up here, it's what I gathered from my few weeks of tinkering with PID loops recently [20:38:09] Anyway, I am off to take a shower, but be back in half an hour or so [20:38:28] (I guess you say "have a shower", right?) [20:38:36] APlayer: like I said. that's a good TL;DR [20:38:48] I say take, but YMMV [20:39:03] APlayer hit step 97, but I'm still dealing with step 3. [20:39:04] Alright then. See you soon! ;tell me if there is anything in my absence [20:39:57] My issue is that I KNOW that I could find the perfect solution, but since I didn't pay attention in class, I don't feel like just playign around with the numbers is good enough :/ [20:40:07] Like I know enough to know that I'm an idiot [20:41:06] anyone want to watch that 300k tonnes asteroid hit kerbin? [20:41:17] I'm reverting the craft to add an attempt at stability, in the idle hopes that it will not screw things up worse. [20:42:14] wow... it actaully burned up before it hit the ocean [20:42:42] skin temperature model is probably a bad thing for asteroids of this size [20:42:54] or it needs to be scaled with asteroid size [20:43:01] entering the atmosphere at 33km/s probably didn't help [20:43:09] to estimate when it would actually disintegrate [20:57:23] your asteroid burned up? [20:57:37] are you sure it wasn't the vessel attached to it that burned up? [20:57:44] AFAIK KSP asteroids are indestructible [20:58:53] I had undocked with it [20:59:01] it was now a vessel [20:59:13] I bbl. time for some MArio+mrbbits [21:00:36] i wonder if i can simulate the asteroid with LOTS of ore tanks [21:00:49] probably not [21:01:30] 300 kilotons of ore? lol [21:04:42] well, only 17647 parts [21:04:56] this could maybe run at ~30-60 seconds per frame [21:08:44] ve2dmn: Maybe it disappeared because nothing was attached to it. [21:08:58] But then you track asteroids ... [21:09:04] #KSPOfficial: mode change '+o APlayer' by ChanServ!ChanServ@services.esper.net [21:09:12] Back! [21:09:51] ayyy he's back [21:09:56] Fun thing: I joined to a second accurately 30 minutes after my "See you soon" message [21:10:21] (Not intended, just funnily accurate timing) [21:12:19] Mathuin: How's it going? [21:14:15] What's the borderless window command line flag? [21:15:09] If you do "\?" (Or was it "/?" ?), you should get all command line flags explained [21:15:44] I don't remember them all either, it's just useless when you can look them up anytime [21:16:11] \?

[21:17:12] Yeah [21:17:55] /? actually [21:19:22] https://www.youtube.com/watch?v=VqdyeYXi580 [21:19:22] YouTube - The UAE's Martian City on Earth [21:20:00] with the abbreviation i was thinking what game faction is that, probably mixed it up with uef in supcom [21:20:48] I read ULA instead of UAE [21:21:12] Also, Mars colony simulators are boring [21:21:21] that is the point [21:21:24] Literally everyone and their grandmother has a plan for them [21:24:39] Houston, we've successfully destroyed the flagpole from a suborbital trajectory there! [21:25:28] (Huh, what's wrong with the thing... It used to work :-( ) [21:33:58] Okay, just wasted an hour on the wrong fins. [21:34:06] Deltas are out, winglets are in. [21:34:17] my grandpa got a tablet [21:34:23] that means I got bad ping [21:34:44] Fluburtur: Get him another tablet [21:34:55] he doesn't need one [21:34:59] no one needs a tablet [21:35:02] Mathuin: Did the PID tuning work so far? [21:35:12] APlayer: I cannot tune the PID until I reach a stable intermediate altitude. [21:35:15] Fluburtur: Apparently some people do [21:35:17] speaking of tablets, I got a Switch for the family yesterday, it's pretty darn cool [21:35:24] I am right now using the pidtool tutorial. [21:36:37] Alright, good luck [21:36:43] Thanks! [21:36:59] It's hard to get started with PID loops at first, but they are awesome when they work :D [21:37:09] so im playing on linux, and when launching through steam the game crashes while loading, but launching from CKAN works fine. What's the best way to find the problem to this? [21:37:33] GunqqerFriithian: I have modified the Steam profile to launch the x86_64 version. Have you done that? [21:37:40] steam crashes KSP a lot in linux, it's the stupid overlay [21:38:07] so disable to overlay and launch the x86_64 version [21:38:09] I just created a desktop launcher for the KSP file directly and don't launch through steam at all [21:38:14] how do I do the second one? [21:39:00] Mathuin: how would I go about doing that? [21:39:31] The desktop launcher is just a file. Open it in gedit. [21:39:38] #KSPOfficial: mode change '+o Supernovy' by ChanServ!ChanServ@services.esper.net [21:39:59] Evening, Gentlemen. [21:44:54] hiyas novy [21:46:33] anyone used the USI Konstruction grabber lately? I kinda want to use one on my drydock, but every time I've used it it's been unable to grasp objects and instead just bounces them around when I try to grab with it [22:12:50] Maybe it's my crappy rocket, maybe it's my technique. I tip 5 degrees at 50 m/s, and let it drift slowly towards the horizon. For some reason, that seems to happen around 23k -- way too soon. [22:13:16] My orbiter turns into an ICBM. [22:19:31] you know what to do [22:19:40] It starts with MOAR [22:20:01] instead of fixing the staging in the VAB I do it on the launch pad every launch [22:20:04] I'll give you the phone number of a good friend who is interested in ICBMs [22:20:13] his name is Kim you might know him [22:21:58] Mathuin if you're doing a traditional gravity turn and hitting 0 pitch too early you're either starting your turn too early or have too low TWR [22:22:24] madmerlyn: my TWR is 1.75 and constant throughout, and I mentioned my turn start point. [22:22:27] because your nose is getting pulled down faster than your ap is raising [22:22:47] 5 degrees at 50m/s seems like a pretty hard nudge [22:23:03] Should I increase speed or decrease angle? [22:23:32] probably both, I'd do like 3 degrees at 80m/s or something [22:24:33] I'm also hoping to get bigger reaction wheels first because the rocket is unstable initially. [22:24:35] my kOS script, which I admit probably isn't 100% best efficiency, does a manual turn of 1 degree of pitch every second [22:24:51] it actually does it in 0.2 degree increments every fifth of a second though [22:24:55] How do you stay on target? [22:25:10] what do you mean? [22:25:15] The early parts don't have much stability. [22:25:35] oh early career I just overpowered when I didn't have the tech to be precise [22:25:59] but you can still be stable if you do stuff like fuel priority and autostrut to prevent noodling [22:26:24] The ship is sturdy, it just gyrates like an intoxicated pole dancer. [22:26:29] like if your first stage has 2 T-800 tanks, make sure the bottom tank has higher fuel priority than upper tank [22:26:49] so your CoM stays up in front of your thrust [22:27:51] I do that with smart parts, limit the top tank from draining until the bottom tank is almost empty. [22:32:04] ooooor make them equal so it drains like a real rocket [22:32:16] also nothing to do with thrust [22:32:26] wrt thrust they prefer the CoM being closer [22:32:49] Yeah, it's way too spinny to wait for 80 [22:34:18] but when you're thrusting in atmosphere the drag becomes a factor and having the weight in the back is no good right? [22:34:53] that's why darts have all their weight in the tip and not in the center or rear [22:35:04] neither is mass too far forward, since you do want to be able to steer [22:35:09] making them equal balances it [22:35:44] The rocket actually rotates a lot around its direction of thrust, not sure why, it's like SAS is overcorrecting. [22:36:17] it you're going to do a gravity turn without manual steering you shouldn't have SAS on at all [22:36:38] I have SAS on until 10 m/s after the initial turn, to make sure it actually does the turn. [22:37:54] Trying it without SAS on at all... [22:38:13] also early rockets I always put fins on the bottom [22:38:26] takes them from being really hard to get right to being super crazy stable [22:38:28] I have winglets [22:38:54] The SAS was causing trouble, I think. [22:39:10] yeah for it to be a true gravity turn gravity has to do all the steering :P [22:39:18] otherwise it's a manual turn [22:39:47] and KSP's SAS has a habit of trying to compensate every movement, it oscillates a lot [22:41:00] I recently learned you can temporarily disable SAS by holding down F [22:41:08] I use that to make SAS calm down sometimes [22:41:44] or when I'm landing a plane and using SAS to help hold pitch, I'll hold F while making steering adjustments so SAS doesn't push my nose around trying to "correct" it [22:44:30] #KSPOfficial: mode change '+o Supernovy' by ChanServ!ChanServ@services.esper.net [23:00:41] Okay. 3 at 80 m/s, no SAS, and I get much further. [23:02:31] Almost too little turn at that point. :-) Pitch doesn't hit 80 degrees until an altitude of 13.4 km (apo 19.8) [23:25:27] 5 @ 80 was pretty much perfect. Now I'm killing myself at the staging point. [23:34:33] And staging was killing me because I forgot to relock the steering. Finally able to tweak the proportional gain constant. [23:40:43] Or not. Every tweak seems to make it worse. Sigh. [23:41:03] On the bright side, I did make orbit which was my goal. [23:54:37] What are you trying to make? [23:57:24] Today's goal was to get a career game started using kOS to control unmanned craft. [23:59:31] #KSPOfficial: mode change '+o Supernovy' by ChanServ!ChanServ@services.esper.net
