[07:24:34] that too [07:25:12] Incidentally, something you set outside in a clear moonlit sky will be colder than something set under a roof, but otherwise in the same outside environment [07:25:44] (blackbody radiation from the roof dwarfs reflected moonlight) [07:27:51] Likewise for something set outside in a clear moonless sky [07:28:22] yep! [07:28:39] they never checked this of course [07:28:44] others did [07:28:44] The baleful cold gaze of the hateful stars [07:31:13] As Medlife Crisis often points out, correlation is not causation [09:44:38] https://twitter.com/olimould/status/1295636051017465856 [09:44:38] Apparently, the new Microsoft flight sim has used AI to map the entire world. But it's not done it all that great,… https://t.co/2uM4I1DI6n [10:19:56] Althego, it's the game of the future [10:20:12] AI might be great at predicting the future [10:21:05] Since tourism is looking bleak right now, blocks of flats might be a more profitable use of the land ;) [11:37:53] (local) leet time [11:47:38] You mean, l337 71m3 [13:37:41] #KSPOfficial: mode change '+o Judge_Dedd' by ChanServ!ChanServ@services.esper.net [15:22:21] Last message repeated 1 time(s).

[17:43:00] (can be refuelled in low Minmus orbit) [17:43:48] Action: FLHerne still isn't very good at spaceplanes [17:48:13] Also, I really wish there was a half-length Mk1 liquid-fuel tank [17:48:38] quite a lot of delta v from a plane with all those cabins [17:49:02] obviously swap to rapiers and nuke [17:49:18] lose one crew cabin and replace it with fuel [17:49:44] the docking part is also quite heavy if i remember correctly, just stick a docking port on top [17:51:51] Too much wing area for my taste of space planes. The aerospike just adds weight, a good profile should work without [17:52:26] (but the wings look cool) [18:00:18] Althego: I don't have Rapiers or a nuke, it's career ;-) [18:00:30] day how many? [18:00:33] And the crew cabins are what it's for [18:00:44] FLHerne: drop tanks then [18:00:50] No idea [18:00:51] yes that is a sane solution [18:00:53] you are pretty maxed at your tech level [18:00:55] if you dont want to make it ssto [18:01:02] and 600m/s with it is already pretty good [18:01:04] which is a pointles endeavor except for bragging rights [18:01:09] I have a spaceplane with a Mk1 crew cabin that can get to Minmus and back without refueling [18:01:17] (barely) [18:01:25] So I figure it should be possible [18:01:29] and actually losing tanks costs you in a loss of few thousands [18:01:34] but everything else comes back [18:01:50] Althego: I want SSTO for the bragging rights :D [18:02:02] Drop tanks can be plan B if I can't make it work [18:02:22] the problem is, if you want a big payload, you need more engines, which means more fuel, that further increases the engines [18:02:31] and you end up with something like 3 times this big [18:04:00] FLHerne: mk3 or drop tanks [18:04:09] or nukes/rapiers [18:04:15] yes because it becomes big, the mk3 is a good solution [18:13:14] How draggy are different kinds of landing gear? [18:13:31] It's annoying to have tailstrikes unless I fly really carefully [18:13:33] generally not too much if they are retracted [18:13:43] But I can put up with that if it saves me anything [18:27:04] Since you should reduce your wing area as well, you should go fast and not pull very hard on the stick ;) [18:31:16] FLHerne: calculate your maximum possible delta-v on rocket power [18:31:30] assuming you start from 1400 m/s and suffer no aero/gravity losses [18:32:38] if it is lower than your required delta-v for minmus from that position, abandon idea for obvious reasons [18:32:54] and ofc with zero extra LF [19:05:53] electron is scheduled again, so is the self igniting one [19:07:31] so saturday morning may be quite interesting [19:08:04] or around friday midnight for americans [19:08:40] https://www.youtube.com/watch?v=x0NVb25p1oU [19:08:40] YouTube - KATICA ILLÉNYI - STAR TREK (theremin) [19:13:35] #KSPOfficial: mode change '+o Judge_Dedd' by ChanServ!ChanServ@services.esper.net [19:44:35] With a bit of tweaking it's up to 970m/s left over at LKO https://www.flherne.uk/files/Screenshot_20200827_204030-1.png [19:50:07] (on the first launch of this version) [19:50:19] So I think it should be feasible [19:50:35] Without being *too* huge [19:52:26] Maybe even with this version if I play trial-and-error with the launch profile enough [19:53:29] consider bruteforcing your way with 4x jets + 1x aerospike [19:53:48] that allows you to leave atmo at 20-30 degrees angle at full speed [19:54:02] and usually saves more fuel than 1 extra engine loses [19:54:20] But then it would be ugly :p [19:54:55] (also, where would I put the 1 aerospike?) [19:55:05] 3 on tail [19:55:37] 1.25m ending with aero and 2 on that [19:55:56] thrust would be somewhat imbalanced, but manageable [19:56:21] https://www.flherne.uk/files/Screenshot_20200827_184000.png < that version almost has the space [19:56:56] Hm, I need to put the docking port the other way up, otherwise the tail will hit my station... [19:57:14] it would not be higher than your present tail [19:58:03] The present tail is too high ;-) [19:58:11] (or rather, too close to the docking port) [20:02:16] Right, so with this version I've got easily enough Δv for a Minmus flyby, but not to make orbit [20:02:31] Perhaps with a Munar gravity assist... [20:10:46] Muahahaha http://www.flherne.uk/files/Screenshot_20200827_210938.png [20:14:39] #KSPOfficial: mode change '+o raptop' by ChanServ!ChanServ@services.esper.net [20:15:20] #KSPOfficial: mode change '+o purpletarget|ktns' by ChanServ!ChanServ@services.esper.net [20:25:59] Hm, so designing a trajectory where I actually *hit* the moon was...not such a great idea [20:26:03] (:facepalm:) [20:27:02] Ranger program?\ [20:27:08] s/\\// [21:24:16] FLHerne: but why the aerospikes? [21:24:25] oh, you don't have the Rapiers yet, right? [21:24:48] right [21:25:40] Action: FLHerne still trying to get the craft above to Minmus orbit :p [21:25:54] (having got distracted by IRL stuff for a while) [21:59:29] #KSPOfficial: mode change '+o raptop' by ChanServ!ChanServ@services.esper.net [23:02:37] bees: "pretty much maxed at your current tech level" indeed :D /home/flh/Pictures/Screenshot_20200828_000058.png [23:02:46] Er, http://www.flherne.uk/files/Screenshot_20200828_000058.png [23:05:15] (sadly, not *quite* able to rendezvous with the station, but I can send a lander over) [23:21:11] and how much heavier it was compared to initial version? [23:52:48] Marginally, 35 tons against 31 [23:53:31] I've designed a version with slightly smaller wings, RCS and a docking port that doesn't risk knocking the tail off [23:53:45] But testing that can wait for tomorrow, because I should sleep :p [23:55:10] heh.. much testing, yes, been there, done that [23:55:15] Of course, in the time I've spent fooling about with this thing, I could have researched Rapiers probably twice over [23:55:34] But constraints are fun :-) [23:57:55] lol.... [23:58:27] constraints... me: doens't bother to upgrade VAB/SPH or runway or launchpad for as long as can in career
