06:02 <discord-> 王​小谦同学. — IRC is so active today

06:07 <discord-> 王​小谦同学. — @egg Just wondering if there is every planet's gravity model

06:07 <discord-> 王​小谦同学. — for RSS

08:17 <discord-> e​gg. — @王小谦同学 only the earth and moon for now; we should add Mars

08:19 <UmbralRaptop> So, does this mean that Saturn's rings are massless?

08:37 <discord-> e​gg. — @王小谦同学 many planets (in particular the giants) have a J2, but not an extended gravity model

08:37 <discord-> e​gg. — @王小谦同学 it's described in detail here: https://github.com/mockingbirdnest/Principia/blob/master/astronomy/sol_gravity_model.proto.txt

08:50 <discord-> e​gg. — @Sir Mortimer https://earthobservatory.nasa.gov/images/84333/the-science-of-sunglint

09:05 <discord-> D​amien. — sunglint for spotting oil slicks

09:05 <discord-> D​amien. — pretty clever

13:23 <discord-> 王​小谦同学. — @egg Thanks

13:24 <discord-> 王​小谦同学. — Also, are there anyone that is making Earth images out of SSO satellite images?

13:24 <discord-> e​gg. — what do you mean?

13:26 <discord-> e​gg. — @王小谦同学 do you mean whole-earth images? There's a Terra MODIS composite here https://svs.gsfc.nasa.gov/2915

13:33 <discord-> e​gg. — @王小谦同学 there's a Suomi NPP VIIRS composite here https://www.nasa.gov/multimedia/imagegallery/image_feature_2159.html

13:38 <discord-> e​gg. — @王小谦同学 Suomi NPP VIIRS again, whole-earth night composite: https://earthobservatory.nasa.gov/images/79765/night-lights-2012-map

17:16 <egg> TIL there's an ocean colour forum https://oceancolor.gsfc.nasa.gov/forum/oceancolor/topic_show.pl?tid=2794

17:30 <discord-> e​gg. — @Sir Mortimer OK we definitely don't want to set a blanket maximum on solar elevation; possibly gathering less science under (ideally properly-computed) glint conditions, in a biome-dependent way (oceans strongly affected, biomes that have rivers and lakes a bit albeit less so, etc.)

17:30 <discord-> e​gg. — @Sir Mortimer you could have fun ad hoc contracts requiring observing under glint conditions of course, for oil slicks and whatnot

18:01 <discord-> K​obymaru. — mechjeb can't really be coaxed into flying principia maneuvers, right?

18:23 <discord-> D​amien. — It can

18:23 <discord-> D​amien. — Set active engines, inertially fixed and add to navball then plan the maneuver

18:23 <discord-> D​amien. — Then close principia

19:57 <discord-> K​obymaru. — ok, I'll try that thanks

19:57 <discord-> K​obymaru. — is there something to override the alitutde time warp limits ? Could that be a bad idea or would Principia handle it?

19:58 <discord-> K​obymaru. — Because the stock collision detection sure got wonky at high tiwarp

20:02 <egg|cell|egg> What do you mean

20:03 <discord-> K​obymaru. — I'm just wondering if principia can handle higher timewarp at low altitudes than is allowed in RSS

20:03 <discord-> K​obymaru. — oh damn, that orbital decay in low moon orbit is not to be underestimated

20:04 <egg|cell|egg> Hahahaha

20:04 <discord-> K​obymaru. — pretty cool watching a scott manley video about it and then experiencing it on your own cracft

20:06 <discord-> K​obymaru. — trying to timewarp through a lunar cycle and maintain an orbit at 130 km, but that requires quite some station keeping 😅

20:06 <discord-> K​obymaru. — thanks again for the selenopotential @egg

20:07 <egg|cell|egg> Principia will detect going through a planet much better than stock, see https://twitter.com/eggleroy/status/94251953136857497

20:07 <egg|cell|egg> Um

20:07 <egg|cell|egg> https://twitter.com/eggleroy/status/942519531368574977

20:08 <egg|cell|egg> But it will not detect going through a mountain

20:09 <discord-> K​obymaru. — man I really need to check out this vessels orbit in a few months

20:19 <egg|cell|egg> You can put your vessel in a repeat ground track orbit, it will would a bit but go back to the same state

20:19 <egg|cell|egg> s/would/would wobble/

20:22 <egg|cell|egg> https://twitter.com/eggleroy/status/1083545992899846144

20:54 <discord-> K​obymaru. — yeah I think scott manley had it in his video

20:54 <discord-> K​obymaru. — did you watch it?

21:51 <discord-> K​obymaru. — Moon probes arrival

23:20 <discord-> S​ir Mortimer. — erm... houston we have a problem

23:20 <discord-> S​ir Mortimer. — I can't get my flight plan window back 😦

23:32 <egg> ah

23:32 <egg> yes

23:33 <egg> um

23:33 <egg> know issue

23:33 <egg> um

23:33 <egg> https://github.com/mockingbirdnest/Principia/issues/2158

23:34 <egg> don't switch scenes with a flight plan that has no manoeuvres (until the next new moon, when this will be fixed)

23:34 <egg> I think this gets persisted by vessel so it's rather annoying

23:35 <discord-> e​gg. — @Sir Mortimer ^

23:36 <discord-> S​ir Mortimer. — thanks 😃

23:38 <discord-> S​ir Mortimer. — I'll just leave my minmus probe in it's parking orbit until then.

23:46 <discord-> e​gg. — @Sir Mortimer @𒀯 𒄷 𒄈𒀭𒁇 updated the illumination section again; will move glint to its own section, since it is water-specific (or at least biome dependent, considering rivers and lakes) and probably has its own interesting mechanics (if we want to have oil spill contracts or fancy experiments that look at glint on purpose like 碳卫星) https://github.com/SirMortimer/Kerbalism/wiki/Sat

23:47 <discord-> S​ir Mortimer. — nice

23:47 <discord-> S​ir Mortimer. — this page is a nice read by now 😃
