[03:02:16] ;mission [03:02:16] XXCoder: You try to go faster than c. You are sued by Apple. [03:02:37] apple: big supporter of big physics [03:04:12] Rounded corners on your light cone are patented [03:51:13] #KSPOfficial: mode change '+o Althego' by ChanServ!ChanServ@services.esper.net [04:04:48] hirys [04:46:05] morning [04:48:16] star [04:52:19] hehe irys sings otome no policy from sailor moon. throwback to a different time. [07:57:57] zombanwa [09:55:09] looks like SpaceX gave up on the heat shield tiles for SN20 and will just fly it... [09:55:18] that would be a typical SpaceX thing to do [09:55:44] it will not be reusable anyway [09:55:58] On the other hand the flight will not happen in August, maybe mid of September from their progress of the launch table and tower right now [09:56:11] but then this test will not include the heat shield, which is a crucial component [09:56:17] they need to finish the tank farm, test it, test SN20, test B4, etc. [09:56:41] SN21 is already in production, B5 parts can be seen, too [09:59:07] Heat shield testing is important, but I guess it can wait for another launch. [09:59:21] at least based on the red markins they know that the current version of the heat shield is not usable [10:03:22] Althego: the opinion I heard was that those tiles were attached too quickly by workers who didn't know how to properly handle them [10:03:44] that could explain why only the top part is affected [10:16:19] that means the workers didnt have sufficient training [10:16:25] process error [10:19:45] They should've taken the water cooling route. :D [10:22:34] the methane evaporation thing? [10:22:55] completely new and requires pumps and plumbing [10:22:58] Water has more heat capacity. [10:23:06] But it's more corrosive. [10:23:45] The methane is under pressure. [10:24:17] Althego: no, water, really just water. Pump it out of pores on the hull and you get a cooling effect [10:24:19] but will it flow to the tank exit during a belly flop? [10:24:31] some intercontinal rockets is it for their payload... [10:24:37] .oO( well, more like blowload ) [10:26:13] There are salts in fire extinguishers that absorp heat during decomposition. Mabye a solution of such a salt could be used. But it might not be feasible to make it on Mars. [10:36:20] On Mars you probably don't need that heat shield [10:36:55] idk, we still have to bleed off that delta-v. [10:37:11] And if we didn't need it, would we carry the salt solution to Mars and back? [10:41:14] the salt in the extinguishers is from covering the flameable material not for cooling iirc [10:41:50] water is basically enough. [10:41:50] May be both cooling and formation of non combustible gas. [10:42:06] But you don't want water sometimes. [10:42:14] And for Mars the stainless steel should have enough heat capacity to take the reentry [10:42:17] e.g. for high voltages. [10:42:48] dry extinguishers just cover everything in non-flamable powder :) [10:42:57] never breath that stuff in though... [10:43:06] I did, a bit. [10:43:17] Found an "empty", dented extinguisher. [10:43:26] Took it home as pressure vessle. [10:43:32] had 15 bar N2 and powder. [10:49:55] Some ammonium phosphate, IIRC. Doesn't sound very dangerous. [10:51:03] it's not the stuff, but the particle size [10:51:11] small enough to get deeeep into your lung [10:51:18] aaaight, time for some sick kerbal moves [10:51:26] Doesn't matter if it dissolves. [14:03:33] kikkerikii [14:43:46] 2.5 pm, or something? [14:59:40] Hi I have a question so I got the mod OfCourseIStillLoveyou for Hullcam cameras but if I use it its stuck in loading screen [15:14:01] Action: raptop blinks [15:20:24] . [16:08:52] ;mission [16:08:52] Alanonzander: You hatch an evil plot to steal some important hardware from Mission Control, for the evulz! Your craft bounces off the surface of a nearby rogue comet. [16:09:08] ouch [16:09:29] With a mere 15% reduction in evil, the comet mission would have been a success [16:10:00] only 15% ? wow.
