  1. I stopped watching new Star treks. The films and the series. I can't stand the cinematography with lens flares, constant camera panning, weird grim lightning and colors, and other annoying effects that are overblown and forced at the viewer. Maybe in the future I'll get more will do do it.
  2. Your bar is set way too high. We are getting a really great series on alternative timeline.
  3. That thread is just for trailers, and this one is for the show itself. First episode was already aired. First season starts in 1969, but now it's the 90s if I got it right. Flat panels were already commercialized in the 80s. It was in the second season I think. "Safety belt"... I can't comment without spoiling.
  4. If the ring was the only structure, it would require diametrically opposing thrusters so that the center of torque is in the center of the ring where the center of mass is. Otherwise, there's a netto force causing tumbling and orbital change. However, the ring is not the only structure. It sits on a supporting structure that has large solar panels. Center of ring's mass is not at the center of station's mass. The whole design is a mess that makes no sense...
  5. I couldn't find another thread on this show, so I'm continuing here. There is no need to open a new one. Season 3, episode 1 has been released. Here is a trailer for the new season. SPOILER
  6. I really love this mod. It has revolutionarized an important part of the game design and the impact on the computer resources seems to be smaller than with ugly stock plumes. I'll never understand why developers cling to obsolete stuff. This should become stock. Anyway, I'd appreciate if KSPX's LV-NB ("Sisyphus" Atomic Rocket Motor) got a Waterfall plume. If I remember well, it was the first non-stock nuclear engine, a 2.5 m workhorse. I used it extensively for my Kron missions. It got a a RealPlume configuration, but it would be nice if Waterfall had one, too.
  7. https://www.vice.com/en/article/epxjjj/years-of-early-alien-hunting-data-are-at-risk-of-being-lost-forever This is just sad. The title mentions data, yet the article talks about hardware. I suppose data is on those machines. I joined [email protected] I think like two years after it started, grinding its bytes with my 1 GHz CPU. Nice memories.
  8. At such large scales, "everything orbits everything" in a way, so yes, we could say this is totally the case here and there.
  9. Last couple of years I've been very inactive on this forum, partially because of the pandemic. It sure made a dent on our lives and it's still not over (it wasn't difficult to predict this outcome), but now it's much more manageable with the vaccines and all. People are still dying like flies around the world, let us not forget that. Perhaps there have been some notable changes in the member structure due to this pestilence? Anyone you know?
  10. Finally, someone did this for all those folks who can't afford to run a beefy full sized mod and still want to explore Solar system. Thanks for doing this. And now for the criticism. I will only talk about textures. There are lots of errors and I'm only saying this because the mod is made for RSS. Mercury - basically spot on Venus - the texture is not realistic. Venus has no visible streaks - those appear when data gathered in ultraviolet radiation range is ascribed to blue channel when making RGB color image. The planet looks like a bright, de facto featureless ball because it's covered with sulfuric acid aerosol. It is not yellow, it is not tan, brown, orange nor blue. There's been a decades old controversy where NASA seems to simply refuse to educate the general public about it. Virtually no encyclopedia or online source shows its visual reality and hardly any explains that the colorful images are not realistic. It's pretty insane when you start digging the reasons behind it. The issue is so pervasive that there are even folks out there who fervently guard Wikipedia's page on Venus. Try to put a realistic image of the planet as the title image and suddenly there's an army of weirdos reverting it. True color images of Venus in publications are extremely rare. There's one made by MESSENGER probe and the rest are basically amateur astronomer images who are one of the rare people acquainted with the actual sight. In the public eye, Venus is simultaneously an orange ball, a blue-white striped ball and a yellow-brown smeared ball. It's a weird doublethink (triplethink?) and a truly fascinating issue of the society. So, if you want realism, remove the streaks, remove color and leave very slight cloud texture that is apparent only when one is quite near to the atmosphere. As for the ground, it is illuminated by orange-yellow, ghastly modified sunlight. Color of the regolith under white light is unknown, as far as I know, but it's probably shades of dark gray. Earth and Moon - pretty much what it is. Mars and its satelites - Mars is very close to reality. Phobos and Deimos, on the other hand, have a false color texture. We don't have high resolution images in true color (MRO which made the most detailed images doesn't have proper filters), but low resolution ones show they are basically gray with very slight, if any, brown tint. Afterall, they're captured asteroids. Jupiter - texture is based on heavily processed "citizen scientist" stuff made from Juno probe data. Again, the false information spread virally and thus the incorrect idea that Jupiter has vividly blue-green poles became a meme. The general public now thinks Jupiter looks like a van Gogh painting. It does not. Contrasts in these images are very exaggerated and colors are very saturated. Jupiter looks a lot more mellow and its poles are grayish - there's less photochemical smog so some Rayleigh scattering can be seen, as well as some red light gobbling up by increased concentration of methane in those areas. Io has a false color textures even showing blue-white. Better images are here. http://www.gishbartimes.org/2010/08/exposing-ios-true-colors.html https://www.planetary.org/articles/2629 Ganymede has a very realistic texture. It's usually portrayed as brown with white spots (courtesy of bad cameras on Voyagers) yet its color is much less saturated and contrasts are not extreme. Europa has a false color texture made by Voyagers' camera filters which do not correspond to human vision. Here is a lot better approximation. As usual, features are not flashy, saturated or with high contrast. https://www.planetary.org/space-images/color-global-map-of-europa Callisto is quite close to reality. Saturn - pretty close to reality. More contrast than needed. Poles are not abruptly blue, but grayish, that's good. Tethys, Rhea, Mimas are fine. Dione has a grayscale texture but the overall result is fine. Iapetus is in false color. It is not really brown like chocolate (courtesy of Voyagers' crappy cameras). Its brown is very subdued. https://www.planetary.org/articles/3389 Enceladus is in abruptly false color. It does not have blue stripes. The blue color is false and a result of different processing. Enceladus is pristine white, like freshly fallen snow. Uranus - the lack of typical overally cyan or the horrible encyclopedic green is correct - Uranus is pale blue. Polar areas are not differet as they are in the texture. They show differences only when imaged in near infrared and when that's incorporated as red channel, Uranus stops looking like a homogeneous ball. So, keep the equatorial color and apply it all over the map. Textures of its satellites are mostly ok, although saturation is a bit too high. Remember, this was made by Voyager 2. Neptune - I was afraid it'll be the grossly saturated ultramarine blue which is Voyager 2's poorly processed image. Neptune is slightly more blue-saturated than Uranus. Triton is a bit too saturated and contrasted but it's better than the usualy poorly calibrated stuff used by the media and encyclopedias. Pluto - high resolution parts are best we have, but the low resolution side's saturation does not match. Charon - quite wrong. It's a gray body with hardly noticeable tint difference on the pole.
  11. That bluish light from hydrogen and oxygen reacting in chemical engines is made by the excited species releasing photons. I don't know the exact details which ones are present because it depends on several factors, but it is certainly the chemical reaction that is giving off light and other invisible radiation like UV and IR, in addition to black body emissions of dense gases. Ionized hydroxyl ions come to mind. On the other hand, hydrogen heated to little over 2000 °C, which is the running temperature of NERVA engine, is not plasma just like you said. There are also no chemical reactions going on in the exhaust so the only photon emission is of a hot, dense gas. At 2550 K (NRX A6 had exhaust temperature of 2285 °C), this corresponds to situation as displayed in this graph. (link to simulator) Basically orange plume at the exhaust throat. Not shiny, either. In vacuum of space it would probably be a short, wide, dim, orange plume probably dying off in the engine bell itself. Yes, pink is out of the question, but so is blue. One thing to note is that the blackbody radiation of the engine itself should overpower the glow of the exhaust after short time that it has been turned on. There would be yellow-orange glow coming through the nozzle because the insides would be basically an atomic furnace. Anyone could see it but couldn't live for long to tell the tale.
  12. I haven't logged on in a while so I haven't seen this. This is really excellent work. Well done, man! By the way, I was looking at GitHub's page on this mod and it says: new plume for the NERV engine instead of the pink hydrogen plasma, the NERV now has a realistic heated hydrogen exhaust plume. red in atmosphere because of hydrogen-atmospheric oxygen reaction, and blue heat-radiation in vacuum. Cherenkov radiation is also visible now, coming out of the engine throat. I am not sure about the blue heat radiation so I won't comment on that (yet), but in regards to Cherenkov radiation, why do you think it would be visible? Cherenkov glow appears in dense dielectrical materials such as water. I don't even think there would be ion glow like when there's a strong alpha particle flux impacting air (for example glow of air above the surface of substances such as radium or actinium).
  13. You know what would also greatly benefit from this? Reentry. Waterfall basically uses cones and paraboloids, AFAIK. KSP does have unlocked ability to form reentry trails (something Reentry particle effect renewed now does) but those are highly resource intensive and look pretty horrible. Waterfall could make beautiful rammed bluish plasma in front of the vessel. Stock game basically teaches us wrong, that reentry heating comes from friction with atmosphere, when in reality it's compressed air radiatively heating the body. Friction comes near the end of reentry and isn't that big of a deal.
  14. What do I think? I think it's both pathetic and hilarious and should be dismissed as frivolous lawsuit.
