How? [08:31:52] Oh no, not again :( [08:32:06] it didnt even explode [08:32:28] looks like the bulkhead inside gave up [08:32:29] if it was pressurized how did it shrink so much? [08:32:46] only the top tank was pressurized [08:32:50] ah yes if the internal structure failed [08:32:52] not the bottom tank as you can clearly see [08:32:57] then it would behave likea balloon tank [08:33:21] now we are waiting for scott to explain? [08:33:25] maybe tomorrow [08:33:45] You can see the buckling already from frame 1 [08:33:58] so the bulk head failed which created a huge low pressure zone which crumpled the upper tank [08:34:31] the buckling from the beginning is because of the weight [08:34:40] Why would they only pressure the top tank? [08:34:46] That doesn't make any sense [08:35:04] the top tank without the support of the pressure of the bottom tank should be to heavy to support [08:35:38] this thing only works if both tanks are equally pressured! [08:36:22] whatever the cause t hey are now stuck with sn4 [08:36:42] lot of work wasted [08:37:26] Not wasted :) [08:37:42] They got a great Youtube video out of it [08:37:57] (plus data for future iterations and blahblah) [08:38:30] true, but they would have gotten way more data if it flew [08:39:32] maybe it really was another test to see if the inner bulkhead could hold up to the pressure [08:39:40] and the whole structure [08:41:03] Musk said "Some valves leaked at cryo temp. Fixing & will retest soon" I guess that was before the incident? [08:41:18] and elon is probably asleep so no tweets :) [08:42:08] https://twitter.com/JimBridenstine/status/1245744389692981259 [08:42:09] <✔JimBridenstine> The worm is back!

And a hand gun case? Sounds like a hairdryer to me. A cool hair dryer ;) [11:14:51] Mat2ch, 200 W packed into a pinpoint is pretty extreme [11:15:28] 200 W is the heat, 100 W goes into the laser [11:15:34] I've been following that guy for years. He's pretty crazy :) [11:16:44] The one he made from a tattoo remover was very neat [11:16:58] yes way higher poer [11:17:06] but that ones is not a beam laser [11:20:05] True. But it was powerful enough to wreck his camera just from the dot [11:31:19] is it better to encounter a planet close to it or really far? [11:31:56] for Δv efficiency to circularize I mean [11:34:08] hatrix: For a given final orbit, lower is better because Oberth Effect [11:34:41] But circularizing to a low orbit will take more Δv than a high one [12:14:47] one more expand to the station https://i.imgur.com/jI1CA7c.png [12:14:58] it's nice to have a design that just works [12:15:44] https://www.youtube.com/watch?v=D8-RZmTOtXQ [12:15:44] YouTube - SpaceX SN3 Starship Destroyed - Liquid Oxygen Tank Crumpled [12:15:53] with some explanation [12:25:12] landed 10km for the base :( [12:25:43] 25m/s on Duna seems like a bad idea though [12:26:15] https://i.imgur.com/swvPniN.png [12:26:24] for vertical speed it is a lot. for landing gears horizontally it is fine [12:26:31] ground speed [12:26:33] ah rover [12:26:48] yes i have this rule to never go faster than 25 m/s with a rover [12:27:02] because if you do it flips in the next few seconds because of a tiny bump [12:27:33] 25 is already quite a lot [12:28:13] ahah, going at 115 kmph on Duna [12:28:16] this is stupid [12:28:40] i still couldnt come up with an airplane design that works on duna [12:28:52] I'm currently reading 2001 A Space Odyssey, and they've got a rover going at such speeds on the Moon [12:29:01] even has some thrusters to jump above small craters [12:29:25] in reality the real lunar rovers pulled off only a few m/s [12:29:36] and even that one was one guy only who dared to do it :) [12:29:44] yep, crazy scary [12:30:06] and the mars rovers are something like 5 cm/s [12:30:13] takeoff in 3, 2, 1… https://i.imgur.com/y8evIwL.png [12:30:23] or rather 1.5 rover because the other one is not launched yet [12:30:25] oups [12:30:27] boom [12:32:48] https://www.gog.com/promo/20200401_midweek_sale [12:33:13] I have the X³ but never playe [12:33:15] d [12:33:26] am I missing something? [12:34:34] i pasted the link because there are a lot of space games on this list [12:37:44] all this moon reminded me of welcome to lunar industries https://www.youtube.com/watch?v=_lAfMT5FIZE [12:37:44] YouTube - Clint Mansell - Moon OST #1 - Welcome to Lunar Industries [12:40:40] made 6km, 4 left! [12:40:48] Duna's surface is actually really nice or rovers [12:41:16] if any of those things has an isru unit i would rather just make a parabolic hop. lot faster [12:41:46] the ISRU is on another rover [12:41:57] which was the first to land 4 or 5 missions ago for this base [12:44:24] the 20° degree slopes aren't so nice actually [12:44:44] real world rovers did around 30 deg on duna :) [12:45:00] slightly above 30 in case of all 3 [12:45:08] or rather mars [12:45:08] definitely ok, but at 30ms… [12:45:18] more like 3 cm/sec :) [12:53:19] https://i.imgur.com/LnP69OC.png [12:53:21] :) [12:54:01] the isru unit is that facing wast to east? [12:54:38] it's on the rover on the far lest [12:54:44] i see that [12:54:58] this one https://i.imgur.com/OdJDMbP.png [12:55:09] but the question was if the solar panels can follow the sun [12:55:17] oh [12:55:22] they can do that if it is facing west to east [12:55:30] otherwise they lose efficiency [12:55:31] 138° [12:55:35] 135 [12:55:58] I'll land a large solar array with lots of batteries either way at one point [12:56:06] but just because it looks cool [12:56:11] the rover has enough electricity [13:17:06] #KSPOfficial: mode change '+v eriophora' by ChanServ!ChanServ@services.esper.net [14:43:34] #KSPOfficial: mode change '+o Judge_Dedd' by ChanServ!ChanServ@services.esper.net [15:19:34] great, you can put two motors and set of blades inside the duct, they seem to be both affected by the lift increase [15:19:44] otherwise my torque would have become unbalanced [16:00:28] #KSPOfficial: mode change '+o raptop' by ChanServ!ChanServ@services.esper.net [16:24:18] #KSPOfficial: mode change '+o purpletarget|ktns' by ChanServ!ChanServ@services.esper.net [17:59:12] #KSPOfficial: mode change '+v erio' by ChanServ!ChanServ@services.esper.net [18:18:15] I will never stop https://i.imgur.com/UrTwqcW.png [18:18:43] though it sounds quite easy, onlt +5 kerbals and 1 MPL [18:21:48] finally. made it into eve orbit with only 5k m/s delta v [18:22:12] these ducted fans are really powerful there [18:22:29] wow, impressive [18:22:32] what does it look like? [18:25:41] http://warpology.com/k/eve_ascent_plane.png [18:26:04] it is actually a rocket with some silly wings [18:26:05] oh [18:26:08] what's that thing on the left? [18:26:24] with the orange stripe? that is the duct [18:26:30] hmm [18:26:33] dlc? [18:26:34] inside there are two motors and two set of blades [18:26:39] yes [18:26:42] oh ok [18:27:13] it takes 3 kerbals and it is only 37.6 r [18:27:16] t [18:28:14] ok the two set of engines and blades are a bit cheaty, but in reality there are counter rotating blades, what i tried to simulate [18:28:51] how is it cheaty? [18:29:01] I don't have the DLC, I can't judge you :) [18:29:13] two parts shifted inside each other [18:29:38] but https://en.wikipedia.org/wiki/Contra-rotating_propellers [18:32:19] ok i dont know how to get it to eve [18:32:26] feels ok to me [18:32:31] ahah [18:35:04] any idea what with I could fill that space under the solar panels? https://i.imgur.com/KVzTj1U.png [18:35:24] why do you need that empty space there? [18:35:39] where would I put the solar panels? [18:36:00] on the lab, etc [18:36:00] Just stick them on the sides? [18:36:16] I would put them on the batteries [18:36:30] I wanted to have long "arms" with only solar panels [18:36:31] you can put one there [18:38:04] looks a bit uglier like that though https://i.imgur.com/P2JUii4.png [18:41:59] this thing's going to have a lot of power https://i.imgur.com/8OdAIWw.png [18:45:13] NFE would reduce your part count a lot [18:45:18] If you really need all that [18:45:20] NFE? [18:45:40] ah, near future elec [18:45:42] Near Future Electric [18:45:53] It has bigger/ longer batteries [18:45:55] I don't really like mods [18:57:17] I hope they like barbecues https://i.imgur.com/glWHGaz.png [18:59:50] hehe [19:32:16] I made a handle for my camera https://cdn.discordapp.com/attachments/429717171002933269/695698018590130246/IMG_20200403_201110.jpg [19:33:24] what camera is that? [19:33:31] isn't it too heavy? [19:33:48] oh it's a handle for the plates, you can mount anything now :) [20:12:30] why can you extend antennas when you don't have probe control but you can extend solar panels? [20:12:41] you ca't solar* [20:14:28] Well, with EC you have a chance to notice that you need to open them before it's too late [20:14:44] you're really selling me this mod :D [20:15:47] Hm? I meant electric charge, not NFE [20:15:56] ha [20:15:58] yes, right [20:16:06] I only saw capitals and was like "oh, mod." [20:16:08] Like, batteries take time to run down, unlike losing signals [20:17:07] extending antennas without control doesn't work, either, if the "connection required" difficulty option is on, iirc [20:17:08] it's still easy to forget them though [20:17:24] maybe I'm thinking about limited probe control then [20:20:21] NFE solar panels are beautiful and powerful. not sure how they fit into a career, only played with them in a sandbox [20:21:29] I didn't want to install mods actually because I wanted to unlock the whole tech tree before and get comfortable with everything [20:21:35] but now that's done, maybe I can look into it [20:21:41] ah, "Near Future Electrical" and "NF Solar" are different parts. https://forum.kerbalspaceprogram.com/index.php?/topic/155465-19x-near-future-technologies-19-updates-feb-20/ [20:22:12] https://imgur.com/a/PmTTebZ [20:22:48] wow cute
