  1. This is not a bug, this is how Principia manœuvre execution works: see https://github.com/mockingbirdnest/Principia/wiki/Concepts#flight-planning-user-interface. With Principia, manœuvre execution is either closed-loop by hand (look at map view, cut the engine when the trajectory does what you want), or open-loop based on the countdowns given in the flight plan (this latter approach is hampered by spool-up times in RO though, so it is better to keep an eye on map view). Note that MechJeb has an implementation of the timing-based approach (an « Execute next Principia node » button)
  2. For the new moon (lunation number 265), the new release (Gröbner) is out. It addresses one part of #2400, namely the lag on scene change far from 1951 in the absence of vessels. This means that @scimas’s custom initial states are no longer needed for late-starting games. See the change log for more details. For the convenience of our Chinese users, the binaries can be downloaded either from Google Drive or from 腾讯微云. It depends what you mean by « Keplerian orbital elements » (and possibly on what you mean by « extract »), which in turns depends on what « something » is. I
  3. For the new moon (lunation number 264), the new release (Green) is out, fixing a few bugs (two crashes and a temporary but potentially very long freeze). See the change log for more details. For the convenience of our Chinese users, the binaries can be downloaded either from Google Drive or from 腾讯微云.
  4. This sounds like a symptom of the same issue as https://github.com/mockingbirdnest/Principia/issues/2957 and https://github.com/mockingbirdnest/Principia/issues/2953; it should be fixed in the next version, Green. The Principia window spawns an asynchronous orbit analyser (this is used to give you a short description of orbit you are currently in, e.g., « circular semisynchronous Kerbin orbit » or something around those lines). This is not new, and is not a performance problem in itself (it runs fairly rarely and does so in the background). When the vessel lands, it becomes « unmanageable
  5. That might be slightly less useless; please also film a launch that doesn’t crash, so that we can actually see a transition to lower lag in space (without an intervening scene change), and figure out if it is correlated with something on the Principia side.
  6. For the new moon (lunation number 263), the new release (Grassmann) is out. Support for KSP 1.11.2 has been added. The mechanism for overriding the version check so as to try new versions before we support them has been documented. Note that no support will be provided when this override is used. Some strings were untranslated in the Chinese version; this has been fixed. Thanks to @WC12366 for this contribution. A bug leading to steadily increasing memory usage up to crashing out of memory (#2919), reported by @Al2Me6 and @hxl11211, has been fixed. See the change l
  7. For the new moon (lunation number 262), the new release (Goldbach) is out. Performance has been significantly improved, especially on macOS. Thanks to @rnlahaye for this significant contribution. A bug found by @Robot_V1, which affected the handling of some aircraft, was fixed. The Chinese localization was improved. See the change log for more details. For the convenience of our Chinese users, the binaries can be downloaded either from Google Drive or from 腾讯微云.
  8. Calling Part.Add(Torque|Force(AtPosition)?) is the only way for a mod to apply a net force to a vessel in the presence of Principia. Calls to RigidBody.Add(Torque|Force(AtPosition)?) will have no net effect on the vessel (though they may deform it). Mods that use RigidBody.Add(Torque|Force(AtPosition)?) are Principia-incompatible.
  9. For the new moon (lunation number 261), the new release (Gödel) is out. Support for KSP 1.11.1 has been added. Principia is localized in simplified Chinese. Thanks to @CindyRIng for this significant contribution, and to @Zaikarion for helping with linguistic questions. Some crash-inducing bugs have been fixed. See the change log for more details. For the convenience of our Chinese users, the binaries can be downloaded either from Google Drive or from 腾讯微云.
  10. They are not, which is why the installation process requires installing the right system dependencies metioned (and, for Windows, linked to) in the FAQ.
  11. Please don’t bundle Principia. Instead direct users to the README.md page on GitHub. There are several reasons for that: Principia has its own (system-level and platform-specific) dependencies, which you cannot bundle without a platform-dependent installer: if Principia is provided in a bundle, it will simply not work out of the box; we want users to know where the concepts & FAQ pages can be found, as well as the specific bug reporting procedures, and the readme will tell them about that—Principia is complicated enough that if users get it as part of a bundle, there will
  12. For the new moon (lunation number 260), the new release (Germain) is out. Support for KSP 1.11.0 has been added. The orbital analysis of the final trajectory is now available in the flight plan, making it possible to plan accurate orbital insertions and corrections. See the change log for more details. For the convenience of our Chinese users, the binaries can be downloaded either from Google Drive or from 腾讯微云.
  13. A notice to all Principia users: DO NOT use the « fix » provided in the above post. @100055 you have completely misunderstood how the axial tilt configuration works, and therefore your so-called fix is incorrect. All orientations of the planetary axes are given by right ascensions and declinations in the International Celestial Reference System (ICRS), whose reference plane is the mean equator of the Earth at the standard epoch J2000; in particular, this means that the axis of the Earth has a declination of 90°. This is the convention used by the International Astronomical Union, and
  14. For the new moon (lunation number 259), which is a total eclipse, the new release (Гельфонд) is out. The orbit analyser now provides a short description of the current orbit, e.g., “highly eccentric semisynch. Earth orbit”. The trajectory colours can now be configured, thanks to a contribution from @Flibble (#2816). See the change log for more details. For the convenience of our Chinese users, the binaries can be downloaded either from Google Drive or from 腾讯微云.
