L4[00:31:22] <XXCoder> ;mission

L5[00:31:22] <LunchBot> XXCoder: You use the schwartz. Who cares?

L6[00:31:28] <XXCoder> LOL

L8[00:40:20] <bees> XXCoder: You do something that you've done before. The booster stage is eaten by the space kraken, and the barge it was supposed to land on is eaten by the normal kraken.

L9[00:42:36] <raptop> Given the booster's location at the time, it was really more of an atmospheric kraken

L10[00:42:51] <raptop> The upper stage and payload, however, were eaten by space krakens

L13[01:34:23] <SporkWitch> Izaya: wassat?

L14[01:56:52] <packbart> the normal kraken only eats upright boosters

L44[09:03:29] <Izaya> SporkWitch: 4chan/sci/ space flight general; that link got thrown aroun there a lot recently

L45[09:06:54] <Izaya> on an unrelated note I'd love a mod that's a cross between chatterer and the navigator from rally games

L46[09:53:51] <Izaya> What are my options for up-to-date mods to get telemetry to use in external scripts?

L49[11:20:18] <packbart> what does the rally navigator do?

L50[11:22:02] <packbart> hm. there is that one mod that LGG uses that exports telemetry data into a file (to be read by OBS). can't remember the name

L51[11:22:15] <packbart> depends on what you want to do with it

L52[11:26:03] <packbart> Izaya: https://forum.kerbalspaceprogram.com/index.php?/topic/201967-112x-export-flight-data-to-a-csv-file-mod/ is not the one I was looking for but it seems to be compatible with 1.12

L53[11:33:47] <Izaya> re: rally navigators, they call out upcoming stuff on the course and such, so for KSP I'd like something like "periapsis in one minute" or "100 metres to target" or something

L54[11:34:38] <Izaya> was thinking I could rig up an external script to run espeak to say things based on telemetry if I wanted to do that

L55[11:35:02] <packbart> ah, I see. that might be doable with kOS or Red Onion and speech synth maybe. I'm not sure anyone tried that before

L56[11:35:19] <packbart> yeah, sounds like a plan

L57[11:36:01] <packbart> the thing LGG uses should be able to export all the data for the script, too. I failed to find it in CKAN, though

L58[11:37:37] <Izaya> There's those sim pit connector addons too

L59[11:37:45] <Izaya> I could rig up a virtual serial port if nothing else

L60[11:37:50] <packbart> kRPC is probably dead. that would have been my first suspect

L61[11:38:06] <Izaya> I did find a version of kRPC compiled against 1.12

L62[11:38:36] <Izaya> but I'm kind of eh about kRPC because it's primarily protobuf-based for TCP and the protobuf library for Lua needs an old version of Lua

L63[11:38:58] <packbart> I used the python variant

L65[12:45:45] <Izaya> hmm, not a good start there

L66[12:45:54] <Izaya> installed kRPC, wrote my script, queried the current game scene

L67[12:45:57] <Izaya> frozen for 10 seconds

L70[13:19:58] <Izaya> okay well after that it seems to have found its brain

L71[13:20:08] <Izaya> got a super basic script to call out when Ap and Pe are coming up

L72[13:20:11] <Izaya> so I guess that's a good change

L81[17:05:13] <Izaya> Got a basic docking callout thinger

L87[20:24:04] <Xenofarion> Hello!

L88[20:24:11] <Althego> hi

L89[20:25:10] <Xenofarion> I have a question for someone more familiar with the game than I am :) Is there any way to display the total amount of fuel my spacecraft has on a glance? Or is there a mod for that? I'm trying to design my first SSTO and it's very cumbersome to empty/fill every single tank by hand

L90[20:26:24] <Xenofarion> reason: I'm trying to use Mark Thrimm's formula for fuel: e.g. mass of jet fuel = ~0.72 x mass of payload etc.

L91[20:26:30] <Althego> hehe the empty-fill thing a long recurring issue, i know no solution

L92[20:26:55] <Althego> but the amount of fuel usually not important, delta-v is what is important, and that is displayed

L93[20:27:25] <Xenofarion> I'd even be happy with a little QOL mod that lets me fill/empty every tank at once

L94[20:27:28] <Althego> however the center of mass movement as the fuel drains requires to check it with mpty tanks too, so you still have to do it manually

L95[20:28:28] <Xenofarion> Well, for SSTOs it's not that easy I fear. For space navigation or normal rockets it's no problem to just use dV, but the balance for air breathing engines is a bit more tricky

L96[20:29:39] <Althego> yes, sstos are hard. but i never used formulas for them. still, the fuel thing is an annoying issue with the game

L97[20:30:29] <Xenofarion> I'm shocked that there's no mod for that yet lol. I googled it and didn't find any. At least I found one for switching tanks from Lf to Lf+Ox and vice versa, so that's something

L98[20:31:47] <Althego> there may be one

L100[20:33:11] <raptop> If I understand things correctly, the problem is that the display exists in-flight but not in-VAB

L101[20:33:45] <Izaya> is it KER that adds the "Resources" readout in the bottom left?

L102[20:38:29] <raptop> I think so

L105[21:50:05] <Xenofarion> @Izaya aww yiss

L106[21:50:18] <Xenofarion> this was exactly what I was looking for. Love this community :)

L107[22:25:23] <XXCoder> https://interestingengineering.com/nuclear-salt-water-rocket-is-it-the-only-viable-way-to-get-to-other-planets

L108[22:25:25] <XXCoder> interesting

L109[22:26:21] <darsie> Therefore we've used nuclear salt water rockets so far to get to other planets.

L110[22:27:40] <Izaya> the NSWR is still an absolutely insane concept

L111[22:27:47] <darsie> agreed

L112[22:28:04] <XXCoder> yeah. dunnoi too

L113[22:28:09] <raptop> very much so

L114[22:29:15] <darsie> I'd like some numbers. How big a rocket would spew how much fissile material and fission products?

L115[22:29:45] <XXCoder> im not sure what output is

L116[22:29:48] <XXCoder> might be just water

L117[22:30:06] <XXCoder> unless it explodes

L118[22:30:48] <darsie> https://youtu.be/cvZjhWE-3zM?t=308 The Nuclear Salt Water Rocket - Possibly the Craziest Rocket Engine Ever Imagined.

L119[22:31:04] <darsie> You'd be surprised.

L120[22:32:42] <Izaya> my understanding is that it doesn't just explode, but it's a sustained nuclear explosion

L121[22:32:48] <Izaya> fission explosion, that is

L122[22:34:51] <darsie> 66 m/s flow of fissionable matter salt dissolved in water. In the reaction zone you need a critical mass. So say you have 50 kg critical mass and replace that 66 times/s ... you spew 3 tons of plutonium every second or so.

L123[22:35:13] <bees> that would make for some hefty thrust

L124[22:35:19] <bees> megatons level thrust

L125[22:35:56] <darsie> How long would you burn? 1 minute? That's 180 tons plutonium.

L126[22:36:12] <darsie> Now how big is that rocket?

L127[22:38:13] <darsie> 100x as big? That's 18.000 t of rocket.

L128[22:38:34] <darsie> You can't do it in LEO, as the exhaust would contaminate Earth.

L129[22:39:33] <darsie> So you have to get 18,000 t to GEO or so, or Earth-Moon-L1. Can't use Oberth.

L130[22:41:16] <darsie> So we use Starship to build that in GEO? Pretty sure we'll rather use Starship to go to Mars.

L131[22:45:45] <Izaya> I imagine any nuclear propulsion would end up primarily for orbit-orbit transfer, along the lines of this https://falsesteps.wordpress.com/2013/09/27/the-reusable-nuclear-shuttle-to-the-moon-again-and-again/

L132[22:45:46] <darsie> 700 GW continous

L133[22:45:55] <Izaya> NSWRs are just absolute insanity (in the fun sort of way)

L134[23:02:49] <Xenofarion> Have there been any balance changes to aerodynamics, RAPIERs or LV-N Nervs in the past 1-2 years? I'm trying to get Matt Lownes Duna SSTO to work, following his exact ascend path and can't even get it to LKO without running out of oxygen

L135[23:03:23] <Xenofarion> https://www.youtube.com/watch?v=ifZATdHiBCg I mean this one. *.craft file is linked there

L136[23:11:33] <raptop> I know that there were some atmospheric tweaks in the 1.0.x versions, but I think it's been stable since like 1.2?

L137[23:12:46] <darsie> Xenofarion: Did you mean LDO?

L138[23:26:46] <Xenofarion> darsie: nope, LKO. This thing has dV for days once it's out of the atmosphere

L139[23:27:31] <Xenofarion> I finally managed to do it. Classic case of "git gud". Apparantly I was a few degrees too steep while ascending. Did it now with 17 m/s of Ox to spare. Dafuq.

L140[23:28:01] <Xenofarion> And in the vid he says this thing is super easy to fly with tons of reserves. Almost 300h in and I still suck :D
