  1. I very much appreciate the improvements with 2685/2709 & all the effort ongoing with 2400. Simply put: Thank you (*10n+1).
  2. Now available publically in the Bennu Trek with 3D globe projection (& a >88 million vertices nexus shape model (nexus toolkit) ;-) now, how to add exploring Kerbals to such exquisite detail...lol...Thank you OSIRIS-REx team for capturing this amazing imagery. also a fun animation of particle ejections from Bennu in their recent news release...
  3. I am tinkering with a personal port of a Trappist1e model (to work as a home system with Principia) & perhaps I've not rotated something or I've let something sneak through from the Kerbin template that I should not? Very grateful for suggestions...only seeing this 90 deg rotation of reddish scattering on an @Body[Kerbin] { } planet in the system...the ported scatterer data shows beautifully in this home system with all the other planets based on other templates. Here is the most key image: North Pole view with Sun towards upper left corner additional relevant images in this album: Thank you very much for insights & suggestions!
  4. You might find the following articulation interesting regarding what is needed for kopernicus asteroids & Principia at this post. For myself, I've been considering improving the gravity model & initial state data for Ida & Dactyl for this mods kopernicus interpretation of them & see what happens to them over time in the nbody gravity model. ( I've also been pondering myself how to do a model version of Bennu since the amazing detail of the 5cm mosaic is rather remarkable )
  5. I like the look of 1e KSC with KSP's "Celestial body visual improvements" ;-)
  6. if you add an "asteroid" or any celestial that requires Kopernicus (i.e not as a KSP "potatoroid" asteroid 'vessel' or other vessel model)... then, yes that creates a problem if you have not also created a patch that tells ModuleManager to add the required parameters ( for this same new Kopernicus generated celestial body(s) ) to the respective Principia gravity model & initial state for the specific solar system you are using. For example, if you use "Real Expansion => Real Asteroids 1.2" , while it is discussed in their thread, I do not yet see a patch released by that modder for Principia & there is on that thread a June request for Principia support This mod uses Eeloo based Kopernicus bodies (you can see this in the config file in the screenshot in the second spoiler below). Again: that way of creating "asteroids" etc. will crash Principia if you add those bodies along with RSS without adding configs for them to the Principia gravity model & initial state...something like the configs shown in the spoiler below. These examples use a GitHub user "WC12366" posted zip that contains Principia configs for a bunch of minor bodies. In that comment's zip, Principia gravity model & initial state data is only available for Juno, Pallas, Ida, & Dactyl...so disable Gaspra & the other two for now.... here is a caution note & the two .cfg made from that data as a test which indeed KSP & Principia does at least load (e.g. see screenshot at the bottom of this post): also, here you can see Eeloo is used as a template in the configs: To get more experience you can study the required parameters for RSS bodies in the contents of: GameData/Principia/real_solar_system/gravity_model.cfg principia_gravity_model:NEEDS[RealSolarSystem] {...} GameData/Principia/real_solar_system/initial_state_jd_2433282_500000000.cfg principia_initial_state:NEEDS[RealSolarSystem] { game_epoch = JD2433647.5 solar_system_epoch = JD2433282.500000000 ... } There is a useful description in the Principia github wiki:: The principia_gravity_model configuration The principia_initial_state configuration also useful are the notes at GitHub: eggrobin's explanation: "pozine and orbital elements" via jpl horizons system (also & some RSSnotes ) & for the initial_state vectors: here are screenshots of the settings for jpl horizons which generate the values that match the numbers seen in Principia/real_solar_system/initial_state_jd_2433282_500000000.cfg = principia_initial_state:NEEDS[RealSolarSystem] {..} & notes about data sources for gravity_model in the comments: sol_gravity_model.proto.txt Interesting to see a celestial so small as dactyl (700 m radius for this model) ...
  7. Principia does not work with exoplanetary systems...there is only a nice model TRAPPIST-1 patch made for SLIPPIST-1. RE: "RSS expansion" Principia only supports very specific celestial bodies "No other celestial bodies are supported, so if you do install pozine's pack, make sure you remove all other bodies: if RealSolarSystem is installed and unsupported celestials are found, the game will crash." (also note: those supported 'pozine's pack' celestials listed at that wiki link are now included in RSS by default.) From my message above...please see the procedure in the spoiler that verified proper KSP1.8.1 Principia RSS behavior via RealSolarSystem CKAN install just an hour ago or so...beyond that it would be better for you to request further help by creating a new thread in Gameplay Questions and TutorialsGameplay Questions and Tutorials (or send me a private message):
  8. Since this appears to be a RSS/kopernicus/configuration related issue rather than Principia related...if you still end up with trouble after deleting & resetting up the RSS/kopernicus folders (I'm hoping you use CKAN in combination with manually verifying folders are fully removed) ...& would like some pointers, you are welcome to send me a private message...since I am working on getting Trappist1 working for myself in KSP1.9.1 this weekend anyway...
  9. for clarity, in case someone else encounters this thread in the future...all that needed is the Visual C++ redistributable library = x64: vc_redist.x64.exe rather than all of Visual Studio. https://github.com/mockingbirdnest/Principia/wiki/Installing,-reporting-bugs,-and-frequently-asked-questions#windows-users "Windows users If you get the message "Dependencies, namely the Microsoft Visual C++ 2015-2019 Redistributable, were not found", well, you need to install the Microsoft Visual C++ 2015-2019 Redistributable." _______________________________________________ (However, & mostly for amusement, I will also include one of my favorite posts about windows .dlls by @Lisias ;-)
  10. PML file is described in the instructions pasted below which come from the link pleroy gave you re: "Please follow the steps here and give us a PML file tracing what KSP is doing and what is happening on your machine.": fyi...Getting familiar with Process Monitor is worth the effort ;-) EDIT: also I was thinking...if you do not have the 2015-2019 x64 already installed...you could grab that & install it also & see if that helps clear up any .dll path issues: https://aka.ms/vs/16/release/vc_redist.x64.exe from: https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads (here is my list...I have a few picky old tools that seem to complain if I remove some of the older distributions...so ignore the clutter)
  11. to add to scimas' insights above...in this case I would actually check several of the Fatal logs first to see if they are all the same type of crash... also, if you are using a windows platform AstroGrepPortable (lots of bloatware installer versions on the www...but the one that just downloaded for the link I added here showed as clean in VirusTotal...still make sure to check it yourself) has been extremely useful for me with troubleshooting KSP mods...I use it to search the KSP.log, .cfg files, MM logs, kopernicus, & principia logs all the time...those usually help reveal what is not playing nice together... For example, these mods in your list have me wondering...I would temporarily drag those out of gamedata, reload, & then see if you can successfully create a new principia based save...though for me crashes on save creation generally have been kopernicus related so will be interesting to see what is leading to your crash... Telemachus Reborn "A 3D navball (huge thanks to Lokaltog/KeRD for an awesome implementation)" Persistent Thrust - 1.7.5 "a plugin that allows propulsion systems to operate during timewarp" Precise Maneuver - 2.4.4 if that does not work, then the info logs are helpful to see what Principia was trying to process/create leading up to the crash...if you upload your principia logs to a google drive folder or something I could take a quick peak for you...
  12. check the Principia logs for insights about the crash...those logs are in your %KSP181's root directory%\glog\Principia\ folder...I usually start with the error log...
  13. @moar ssto is there a thread tracking observations of such terrain issues in 1.8.1+? Is this issue observed in any mods other than REX? If you log & eventually share a list of specific lat - lon of crashes with invisible terrain when you notice them on any TRAPPIST1 system planet, that would help me more easily attempt to confirm your observations using the Making History DLC to place test ships near those locations in both REX TRAPPIST1 as exo system v. TRAPPIST1 as the home system ( @AndrewDraws TRAPPIST1 system's worlds are just too beautiful to not enjoy them with the Principia TRAPPIST1 system n-body model ;-).
  14. source: https://www.asteroidmission.org/?latest-news=asteroids-bennu-and-ryugu-may-have-formed-directly-from-collision-in-space " in a new paper published in Nature Communications, scientists from the OSIRIS-REx and Hayabusa2 teams argue that the YORP effect may not explain the shape [“spinning-top” asteroids] of either Bennu or Ryugu....Bennu, the target asteroid for the OSIRIS-REx mission, and Ryugu, the target of the Japan Aerospace Exploration Agency’s Hayabusa2 asteroid sample return mission, are composed of fragments of larger bodies that shattered upon colliding with other objects. The small fragments reaccumulated to form an aggregate body. Bennu and Ryugu may actually have formed in this way from the same original shattered parent body." Rather amazing asteroids & missions...while waiting for the public release of Bennu trek, the similar Ryugu trek has just recently been released: https://trek.nasa.gov/ryugu/ Ryugu Trek (note: the image data is not currently as majestic as for Bennu)
  15. To extend beyond the Kerbal view both into Earth's photographic sky as well as real relative star motions plus or minus a few million years in time ...There is excellent publicly funded software: GaiaSky (link) provides a useful EDU 3D visualization of the relative location of TRAPPIST1 (SIMBAD link) = Gaia DR2 2635476908753563008 in our local region of space over time. Motion Vector arrows show where things are headed relative to Earth's Sun, plus stellar motion becomes readily observable with high time acceleration rates. Aladin (link) provides simple access to beautiful color all sky survey images searchable with a great "Gaia DR2 cone search" feature. Aladin's "Gaia DR2 cone search" generates a layer that is easily shared with GaiaSky & TOPCAT (link) with a couple mouse clicks (right click the layer & select "Broadcast to all SAMP applications" ;-) via SAMP VOTable . GaiaSky will then import the table and automatically focus a star when it is highlighted by 'mousover' in Aladin. This is all working nicely now plus can be 'bookmarked' in GaiaSky release 2.2.6. GaiaSky & Aladin & TOPCAT SAMP with the "Gaia DR2 cone search" TRAPPIST1 & Pleiades NASA EYES on Exoplanets (web version link) also offers an edu relevant view directly in a www browser.
  16. I appreciated @Delay's clarification "just for the record" post above since it made clear for me a long standing question to which I had not yet dug up the answer regarding the CoM of those models. Thus, my sharing a few thoughts & links here: @SynX...beyond the Principia concepts wiki...Principia does many very useful & important things...two of my longtime favorites being the offer of multiple reference frames & leveraging the power of a number of library tools to put celestials in an epoch with an appropriately aligned & rotated coordinate system which enables cartography & then also integrates their mutual interaction in a way that includes the use of gravity models resulting in decent precision astronomy...now Principia has made for us an orbit analysis tool & powerful physics model in timewarp...making KSP a front end for some very useful models of our 'local region of space' (especially when combined with the work of FAR & RO & OhioBob's atmospheres tools & TRAPPIST1 or RSS with some texture corrections) rather than 'only' a fun yet relatively 'haphazard toy universe' . I wish I had computing power & tools like this created & shared openly by thoughtful & dedicated people in such a fun package available to me when I was age 12 to 18. I encourage, especially young students interested in computer science, mathematics, physics, astronomy, and/or astrobiology, to engage & learn & explore with these models...and to build a relationship with (& possibly even delight in) a very real process of human discovery--so effective that over millennia it has produced the collective knowledge & infrastructure/machines/processes/tools we have today--where at some point someone notices 'X thing does not work' and creative people set off to figure out why & thus make a more useful model that empowers the new observer. Maybe, eventually, (I'll keep dreaming anyway) given all the work resulting in beautiful info about 'rotating rubble piles' like Bennu & Ryugu & Toutatis "since we know the geopotential of celestials, we could know their moment of inertia and compute their wobble" -anonymous ;-)
  17. One way to explore the 3D shape: The NAIF Toolkit utility dskexp.exe does make a 99846 vertices .obj from the public DSK .bds file that opens in SBMT which makes it easy to add co-registered layers: 99846 vertices Bennu Model in SBMT Also, given the beautiful & detailed images from the work of the OSIRIS-REx team, some younger people would like me to make a detailed model for them to load in KSP so that they may explore Bennu via their favorite Kerbal(s) doing EVA jetpack 'floats' around a Bennu... thus my catching up on the prior such work from the other thread (& using google search: Bennu site:forum.kerbalspaceprogram.com ) : Following up on this older (2016) 49000-facet version post & this (2016) Gilly based PQS Bennu model that loads...but has issues even at 10x larger radius in at least in KSP 1.8.1 and the older post "[0.90] KSP-Real-Asteroids Missions and Bodies pack" & my recent post in that old & 'expired 'challenge' thread (before I figured out the conversation had moved here :-)... In case anyone has come across a helpful link or two in this direction, I have not yet spotted in my kopernicus/PQS/Unity heightmap reading if there is a process to use very large .obj type shapes (e.g. 100k to 200 million vertices) to create height & normal maps for PQS say to make a 10x or 100x larger scale version of Bennu (since RSS Deimos seems to be about as small a celestial as I have seen work mostly ok so far...). Thanks :-)
  18. I have been thinking recently about a more detailed model in KSP given how much more is known about the shape now... (either as a 'closer to scale' shape model 'vessel' or even if enlarged in KSP to 'moon size' for better handling of a PQS version) the .obj on https://nasa3d.arc.nasa.gov/detail/bennu feels much too plain compared to the detail in the DSK... I see that KillAshleys Gilly based Bennu .cfg post & download link is still available....and appears to load it in KSP 1.8.1 I see that NAIF Toolkit utility dskexp.exe does make a 99846 vertices .obj from the DSK ( .bds file at https://naif.jpl.nasa.gov/pub/naif/pds/pds4/orex/orex_spice/spice_kernels/dsk/ ...that opens in SBMT
  19. trek.nasa.gov has a Bennu portal listed under "coming soon" which will eventually enable you to view the full resolution from any common browser on average+ computers... but until that is released then at least on Windows, "Paint.NET" will handle the full resolution (~800mb file) using about 5gb of RAM: Screenshots: 1) 5cm in paint.net & 2) the NASA treks portal
  20. Indeed something "more scary in the minds of more people" might induce a more effective social response for containment & or even 'die out' more quickly. Additionally worthy of note are a given virus' specifics of transmission...excerpts below suggest that at least MERS appears to have spread via close direct contact = repeated animal to human transmission...not via sustained human to human transmission....as more sequences become available I am interested in what (if any) signs/rates of recombination events are detected using just the normal drift mutations as markers... in any case, Kerbal is one way I remind myself that Earth & Kerbin are cool places in space that have many moments of beauty & fun even if Earth has some not so nice human infecting viruses ;-)
  21. I keep them around as well since KerbalEDU still has not updated past 1.4.5 so links are in the spoiler below. Please Note: The Principia team does tons of amazing great work on this mod & needs to focus on newer KSP versions (which I very much endorse since KSP1.8+ handle large craft better :-). so please remember that those of us who continue to use fatou are 'on our own' = no support. You may also want to save copies for yourself of the current Fuchs since it is also "the last release to support KSP 1.5.1, 1.6.1, and 1.7.x"
  22. [snip] & relative to even the basics looked at in the undergrad program in HumBio core (Stanford) 'way back' in the 1990's, my take is that we are 'fortunate' that SARS-2 is 'relatively modest' so far relative to what can happen even just considering the initial SARS or MERS or influenza strains (e.g. H5 & H7 lines). Airborne or surface transmissible viruses thrive with global travel between dense populations...unless we figure out reasonable ways that we as a global community choose to adopt for daily life & travel that mitigate common ways problematic viruses spread. In consideration of Marc Lipsitch's 2014 points, my encouragement is to take moments of this time as an opportunity to be mindful about informing ourselves regarding types of research being done, what risks are involved, & which risks we each personally are willing to accept or not for both protection regarding 'natural viruses' as well as the rather serious 'strategic' implications if some group discovers an actual way to create a 'universal vaccine technology'...the image below links to the actual NYT article which should be freely accessible:
  23. Wow this is such a handy tool even with large sandbox craft. With the big crafts made possible due to the KSP improvements in 1.8 & 1.9+ this mod can really come in handy & makes it so much easier to add/change specific things like monopropellent, etc so the kids (& me too ;-) can play with different fuel challenge levels, for example, with ISS - Dragon rendezvous scenarios with craft like "SirNoobly"'s pretty ISS 2020 at KerbalX. Thank you @linuxgurugamer for your exceptional effort keeping great mods alive! Working in KSP 1.9.1
  24. @Cochies Your question sounds like it might better fit in a Scatterer thread...however, assuming you are making such changes only for your own personal use & assuming you made a renamed duplicate to make this Planet 9(X) in the image below, I also happen to find interesting your idea. Thus, my one suggestion for you is that perhaps you did not tell Scatterer that the Sun is now the new parent star & not "mainSunCelestialBody = ProximaCentauri" for your renamed "Proxima C clone"...assuming you already duplicated & rename (but forgot to reparent) all the the various Scatterer configs "celestialBodyName = ProximaCentauric" --> "celestialBodyName = Planet9" in the RealExoplanets/Visuals folder... very much looking forward to exploring any or all of these!
  25. @pleroy when you have a moment, a "what to look for" suggestion from you would be helpful to me to gather better info on a Principia fatal KSP crash condition I am encountering: In KSP 1.8.1, I am exploring some setups using various RSB & FASA prebuilt rocket models (i.e. Delta IV, Atlas, Saturn, V, etc) for sandbox study scenarios comparing RO Kerbin v. RO RSS & I've been encountering the following kind of Principia Fatal crash at some of the rocket stage separations. I expect there will be lots of iterations of launches etc with variations (including crazy staging engine, maneuver, etc 'mistakes' we will be making) on these type of rockets so if I know what to look for I expect to be able to get a much better sense for & information about what leads to the crash so i can create more stable study environments. Logs etc in this folder : https://drive.google.com/open?id=1dD4KAfOmW-qH0N98rQ7e4c5nFc8jADVx Thanks!
