[14:09:11] then i choose the atacama desert, at least there is air and an onservatory there :) [14:15:49] *an*? [14:16:38] Cerro Tololo, La Silla, Las Campanas, Paranal,… [14:18:25] I wonder how much water you could extract from desert air per J. [14:18:44] not much in the atacama [14:19:11] So with much energy you'd get some. [14:19:33] Prolly more than on Mars. [14:19:51] not really. you need to keep the surface cool. whatever happens. but there is very little water vapor in the air there, so you cant extract what is not there to begin with [14:20:04] on the mars you could jusg dig up water from the soil [14:20:11] Very little is something. [14:20:25] Just use more solar panels to get more. [14:21:37] There's a paper about how much energy/power you need to extract water from Mars' atmosphere. [14:21:48] I forgot the number. [14:21:57] They used zeolithes. [14:25:23] Landing somewhat [14:25:25] rt [14:25:31] Action: UmbralRaptop 🔪 📱 [14:25:59] Landing somewhere with (sub)surface ice seems easier [14:35:14] #KSPOfficial: mode change '+o UmbralRaptop' by ChanServ!ChanServ@services.esper.net [14:36:24] The results of the simulations show varied performance with significant specific energy amounts for the water collected at VL-1 and VL2, and more reasonable performance at New Houston and the North Pole. At VL-1 production was lowest with an average of 3.8 kg/sol produced with the highest specific energy of 55 kW-hr/kg. Viking Lander 2 had similar results with an average of 4.3 kg/sol produced and a specific energy of 53 kW-hr/kg. [14:36:25] New Houston, with its increased concentration, had more favorable production with an average of 14 kg/sol and a reduced specific energy of 17 kW-hr/kg. Finally, at the North Pole, with a concentration during summer of nearly 10 times that of Viking Lander 1, average daily production was 25.8 kg/sol at the best overall specific energy of 10.5 kW-hr/kg. [14:36:41] http://www.marspapers.org/paper/MAR98062.pdf [14:38:04] hm [14:38:57] Absorption with zeolites and heating with microwaves. [14:42:43] Works everywhere, don't need to dig, robust. [14:43:06] you just need to scoop the ice at the poles [14:43:12] ok, most of it is co2, but still [14:43:24] No, most is H2O, IIRC. [14:43:35] yeah [14:44:22] Sublimating polar CO2 would double atmospheric pressure, IIRC. So 170*2 kg/m2. [14:44:53] Polar water could cover Mars 11 m=11,000 kg/m2. [14:44:59] and that is wht you shouldnt believe everything elon tweets. no point in nuking the poles on mars, there is not enough co2 remaining to warm up the plamnet [14:45:33] There might be enough F to make enough SF6. [14:49:02] The potential for mining fluorine-containing minerals to obtain the raw material necessary for the production of CFCs and PFCs is supported by mineralogical surveys of Mars that estimate the elemental presence of fluorine in the bulk composition of Mars at 32 ppm by mass (as compared to 19.4 ppm for the Earth).[17] https://en.wikipedia.org/wiki/Terraforming_of_Mars#Use_of_fluorine_compounds [14:49:42] hehe how do they know that, only 33 ppm and they have almost no direct measurements [14:51:09] hmm https://www.youtube.com/watch?v=31HAFceuvb0 [14:52:07] Yeah, there's an event related to it Monday morning here [George Mason University] [15:28:06] https://www.youtube.com/watch?v=i5P_6huIJm0 [15:30:39] Encounter with Ultima Thule: The Most Distant Object Humanity Has Ever Explored [15:38:11] #KSPOfficial: mode change '+o UmbralRaptop' by ChanServ!ChanServ@services.esper.net [16:54:23] UmbralRaptop: ooo look https://usercontent.irccloud-cdn.com/file/JEBKMrmx/20191108_115544.jpg [16:54:44] mirorr? [16:55:01] How resource intense is principia? [16:55:03] Althego: the words on the mirror [16:55:13] mathematica [16:55:43] Compared to stock. [16:56:37] 0.5 times stock speed? [16:57:49] ah boring that's the wrong mathematica [16:58:09] hehe is there a wrong mathematica? :) [17:02:03] Althego: this is a policy research company [17:04:37] darsie: depending on number of active vessels/debris/asteroids [17:05:19] cant they just precompute the motion of the planets for a few hundred years? [17:05:30] disable asteroids, kill all debris, try to explore one craft at a time, and you get stock-like speed [17:05:38] it is not the planets that are problematic, but crafts [17:06:21] Do asteroids have gravity? [17:06:23] ah yese those are always htere nad need to be computed [17:06:37] no, but their orbit still needs to be computed against all planets [17:07:01] Orbiting an asteroid would be nice. [17:09:54] stock asteroids are too small to have a gravity field [17:10:02] solar pressure would be higher, probably [17:10:27] not gravity field, but possibility of stable orbits, rather [17:13:15] Yeah, they're kinda small. 100 m for class E? [17:14:43] Still, they're held together by gravity, sorta [17:15:14] mini metro irl https://usercontent.irccloud-cdn.com/file/RGNPZPe9/20191108_121607.jpg [17:15:33] they have way too many overlapping lines, that efficiency is terrible [17:17:53] lel [17:18:08] Fluburtur: did you see my other post [17:18:12] the quebec one [18:49:15] #KSPOfficial: mode change '+v phroa' by ChanServ!ChanServ@services.esper.net [18:55:16] so.. guess nothing too exciting in recent times with anyone? Or did we all just loose our mojo/creativity? [18:56:45] played through technomancer and lost horizon 1-2 recently [18:56:51] trying overload now [18:57:22] ah [19:40:11] https://usercontent.irccloud-cdn.com/file/ES4j1K3g/20191108_143627.jpg [19:40:24] JVFoxy: look who I just paid respects to [19:44:42] #KSPOfficial: mode change '+o UmbralRaptop' by ChanServ!ChanServ@services.esper.net [20:49:27] Last message repeated 1 time(s). [20:49:27] yes [21:18:54] #KSPOfficial: mode change '+o raptop' by ChanServ!ChanServ@services.esper.net [21:26:22] Today in good news: the people doing the Great Observatories studies understand that the SLS is in no way guarenteed. While it's the baseline for HabEx, LUVIOR, etc. any actually selected mission will be built with an understanding of New Glenn, Falcon Heavy, Starship, etc. [21:28:25] hehe [21:28:40] sls is kind of pointless [21:28:44] and expensive [21:29:30] Well, yes. It's decidedly disapointing that shuttle-derived hardware saves no money or time, though. [21:29:53] the shuttle didnt save money either [21:31:35] I guess it was a lesson at reusability. [21:31:48] We had to start somewhere. [21:32:25] yes but dont need to take the same lesson with the same outcome for decades [21:40:24] STS ended up discrediting reusability, if anything [21:41:19] spacex is now reusing boosters. but how much do they save? there is still some refurbishing [21:41:59] I wonder if I should build a trailer for my tank so it can carry some of my stuff to my stand at the maker faire [21:42:19] hehe [21:43:37] Hard to say how much savings. But having a design that works even if fully expendable, and evolving towards reusability seems to have been a very good idea [21:44:56] at least it is not as labor intensive as the shuttle. so even if they save half of the money that is a huge achievement [21:47:07] Even the Titan IV was cheaper than STS [21:57:46] #KSPOfficial: mode change '+o UmbralRaptor' by ChanServ!ChanServ@services.esper.net [21:58:00] #KSPOfficial: mode change '+o UmbralRaptop' by ChanServ!ChanServ@services.esper.net [22:00:13] #KSPOfficial: mode change '+o UmbralRaptor' by ChanServ!ChanServ@services.esper.net [22:00:56] https://kep.cdn.indexvas.hu/1/0/3030/30301/303010/30301061_3349c55a339708895ef150761368ee99_wm.gif [23:38:11] #KSPOfficial: mode change '+o UmbralRaptop' by ChanServ!ChanServ@services.esper.net
