  1. Aine has gotten a complete overhaul. Instead of being an ultra-dense rocky Super-Earth, it is a volatile rich Mini-Neptune with a thick water mantle over a rock-iron interior. I gave it a ring system even though one is unlikely IRL. In the mod, it's from a moon that was shoved too close to the planet by the gravity of its star, ripping it apart.
  2. K2-266Ab, an Ultra Short Period planet. GJ 1018b, a warm water-rich Super-Earth. The plans for the initial release have changed again. K2-266Ab and GJ 1018b will be in the initial release, alongside Aine/C17-2b and the three rocky planets of C13-7. As I mentioned before, I want to focus on just a few planets at first instead of rushing out like a dozen. Also, with the new Scatterer update out, I need to redo the visuals for every planet that will be in the first version. GJ 1018b is done and looks far better than before; in the prior version, the atmo rim was very faint and the day-night transition was very abrupt.
  3. Is Eve's color going to be the result of liquid and gaseous iodine in KSP2? These shots remind me of the version of Eve from the mod JNSQ, where the purple color is also the result of iodine.
  4. The initial release will likely just be the C17-2 and C18-16 systems. C17-2 contains Aine and its moon Aillen, while C18-16 has four gas planets and one ocean planet. This way, I can have an interesting multi-planet system in the first release, and dedicate a lot of time to a small number of rocky bodies to make them very high quality. I'm already working on a new, hand-made texture for Aine.
  5. I love the idea of a young solar system in its first few hundred million years of existence. Are Rask and Rusk also in the Debdeb system? Their new textures seem to have the same heavy cratering as Char and Gurdamma. Ovin is going to be a pain trying to land on. Also, scaling it up to IRL scale, Ovin is so big that it's nearly in the size range of Mega-Earths, rocky (or mostly rocky) planets of >10 Earth masses; examples include HD 21749b, K2-56b, K2-66b, and Kepler-411b. At 1.6x Kerbin's radius (960 km), Ovin would be 9600 km/1.507 Earth radii when scaled up 10x, and a surface gravity of 4G yields a mass of 9.08 Earths and a density of 14.6 g/cm3.
  6. A work in progress moon for Aine. It's about the size of Minmus and is caught between the strong tidal forces of the planet and star.
  7. I've been doing a lot of interplanetary missions in my career save over the last few days, alongside Mun and Minmus contracts. Earlier, I sent a pair of relay probes to Duna, DENCA-1 and DENCA-2 (Duna Equatorial Navigation and Comms Array), to prepare for future missions once I get contracts. However, one of the probes kept glitching out upon separating from the transfer stage. I had no choice but to turn on the unbreakable joints cheat so it wouldn't explode, then I got the other probe into its correct orbit. Going out of physics range caused the glitchy probe to correct itself, and now I can correct its orbit later on. I launched the MOAL mission once a Moho transfer window opened up prior to DENCA arriving at Duna. However, it was a pretty bad trajectory, requiring a significant mid-course inclination change and a 5 km/s capture burn - which ended up costing around >6 km/s of dV and lasted half an hour. Fortunately, I packed plenty of dV into the transfer stage and orbiter. Once captured, the orbit and lander separated, with the orbiter staying in a high polar orbit and the lander getting into an equatorial orbit to prepare for landing. After a mission to finish a contract for Mimas Station, a contract to transmit science from Moho's surface appeared, so I used the MOAL lander to fulfill that. The Mimas Station contract was fulfilled by adding on two of the big orange fuel tanks with 1.25m docking ports, which I'll use for ore canisters that can be filled and deposited by Hyperion and Theia-class transports I developed a few weeks ago. Finally, an Eve transfer window has opened up, and with over 9M funds, I have plenty of cash to spend on four 150-250K probes: The three Freya probes (an orbiter, a science return mission, and a rover), and the Phaethon Corona Sampler. It will use an Eve flyby to get into a lower solar orbit, because its mission is to get all the way down to Kerbol's atmosphere - something I've never attempted before. At least one Eve gravity assist will make the whole thing way more efficient. This first Eve flyby will be able to get Phaethon into an orbit with a periapsis slightly closer than Moho, and an apoapsis at Eve's orbit, opening up the possibility for a second one. So far I've only launched Freya I. It too is aiming for a close Eve flyby to capture, so seeing what the resulting Kerbolar orbit would be like led me to decide to have Phaethon perform a flyby. I won't be doing an aerocapture despite the heat shield; I added WAY too much dV for an Eve orbiter.
  8. WIP revamp for Aine. Its transit geometry suggests it could be in a very eccentric (e=0.48) orbit and be transiting at periapsis, which would make it about 1.8 Earth radii instead of 2.0 Re. The massive temperature swings would probably dry out the equator. WIP initial texture for Melera/C13-7c, a Sub-Earth within the right temperature range to host liquid Iodine on its surface. Future texture iterations will reduce the liquid covering on the surface to some small seas and lakes - and will be hand drawn instead of some garbage from Grand Designer. The color scheme will remain more or less the same, however. Maybe the atmosphere will be changed to a light indigo, but I don't want Melera to feel like Eve but smaller.
  9. Added on to Darwin Station in LKO and tested out the in-space construction feature for the first time. Then I sent a couple of missions to Minmus. First was Minthe II, which had a 7-seat transfer module to pick up Val from Minthe Base and Peter stuck in LMO, as well as a reusable lander that could function with or without crew. Next was the core module for Minthe Station. I docked and refueled Minthe Lander there, and eventually the station will have fuel conversion and crew. To cap off today's station work, I continued my contracted expansion of Mimas in low Munar orbit, and used the construction feature again to clamp down a weak docking joint. It's stuck at an angle now, but Lodry Kerman will be able to fix it later on. I just need another ~3200 units of LF on Mimas to complete this contract.
  10. Every time the Kerbal jumped, he stood 1m above where he was before, standing on nothing but air. I shot him up with a canon with gravity hacked and he smacked into the launchpad. Then when I tried to get him up, the glitch appeared.
  11. I started a pure-stock Career Mode save a few weeks back and have almost fully unlocked the tech tree. I have two contracts for Eve missions: put a probe in a specified orbit, and perform a flyby and return the craft to Kerbin. Two probes (Freya I and II) will be launched together to fill those contracts, and Freya I will remain in orbit as a gravity/resource scanner and relay probe until I can establish a proper network. However, I want to take full advantage of the upcoming transfer window, so I've been designing Freya III, a rover that'll land near Eve's largest crater. Originally I was going with an Oppy-style rover in a giant aeroshell, and would be deployed with a skycrane. This had several problems - lots of staging and extra probe cores, the possibility of the aeroshell overheating and exploding, the sheer size of the aeroshell, the solar panels breaking off, and the possibility of not being able to remove the skycrane one the rover had touched down. I went back and completely redid Freya III's landing method. Instead of a skycrane and an aeroshell, it'll just be stored in a 2.5m cargo bay with a heat shield and parachutes. I also swapped out the panels with a radioelectric generator and added some more Mystery Goos. I tested this twice using the stock HyperEdit, first on Kerbin and then on Eve coming from a far steeper angle than I would in the actual mission. It performed well both times (and don't worry, I reverted the flight. I'm not cheating my way to Eve). I was hoping the lander can would act as a relay for the rover, but apparently not. That will make Freya I even more crucial. I might put it in geosynchronous orbit above Freya III's landing site until the rover completes its mission, then the orbiter can enter an upper-atmo grazing orbit for its main science operations.
  12. "What did you do in KSP today?" Good question
  13. I'm surprised this thread is still going lol. Ida was really bad up here in New England. I didn't think much of it since it was a remnant system, but wow did Ida pack a punch. My town got 7-8 inches of rain and caused the worst flooding since Hurricane Irene in 2011. Thankfully, neither me nor anyone I knew lost power. The cause of Ida's devastating flooding was due to it interacting with a trough in just the right way to both enhance its rainfall and make it a potent tornado threat; without this interaction, Ida's remnants would've produced 2-3 inches maximum. Hurricane Sam from late September to early October was a very impressive "fish storm" - one that remains out to sea without impacting any landmass. On September 26th, Sam reached peak intensity, but a recon flight that would've been there in time was rescheduled to later in the day, and once it arrived the storm had begun weakening due to an Eyewall Replacement Cycle. Recon found a pressure of 929 millibars (mbar) when the eye had just collapsed, and the pressure rose exponentially (5mbar between passes 1 and 2, then 10mbar between passes 2 and 3). Backtracking to Sam's peak appearance a few hours prior, it probably peaked as a 160-165 mph Category 5 hurricane with a central pressure of 924-926 mbar. The heat content of the waters Sam was over were able to support a maximum intensity of 925 (+/-3) mbar, and using the KCZ pressure-wind relationship, the 924-926 mbar estimates would support 140-145 knots (160-165 mph). Dvorak presentation (as shown below) was classifiable as T#7.0, or 140 kt/160 mph. Sam would slowly recover from the EWRC and peak as a 150-155 mph high-end Category 4 several days later, and had a third and final peak before turning into a non-tropical cyclone in the far northern Atlantic. Sam maintained Category 4+ status for longer than all but a few Atlantic hurricanes in the last 50 years, and longer than any other storm this year.
  14. Scatterer seems to have issues with objects beyond a certain distance from the Sun, leading to the Scatterer effects of C16-35b to not work correctly. They often don't even face the star that's literally right in front of it. Therefore, the C16-35 system will not be a part of 0.1, but will come in a slightly later update once I get this issue fixed.
  15. Progress report: The textures for Karkinos, Onoi, Aine, and Enyalius are done Nephelion might be completely re-worked; the other gas giant textures and Scatterer are finalized The rocky/oceanic planets all have working realisitic atmospheres; Aine might need to be revamped a bit due to issues with its water content Flight view surfaces of Karkinos and Onoi need work Flight view surfaces of Aine and Enyalius are just about done All of the gas planets except for Kai need new realistic atmospheres WIP rings for Atlantiades
  16. I finally have nicknames for the C18-5 planets. Since the system is within the constellation Cancer, the planets have been named after names given to the constellation by the Greek astronomer/mathematician Eratosthenes. Karkinos (C18-5b) Onoi (C18-5c) Kai (C18-5d) Onoi/C18-5c has gone through like four different textures so far. I can never get something that I'm truly satisfied with. While I am mostly happy with the surface texture, this iteration of clouds didn't come out that great. I'm giving the planet a thick atmosphere, a mix of volcanic outgassing and its primordial envelope, mainly comprised of carbon dioxide and hydrogen sulfide, with small amounts of other volcanic gases (CO, CH4, SO2) and traces of hydrogen and helium. For a planet of this temperature (Teq=885 K for 0.3 albedo), the available cloud-forming molecules include sulfides and chlorides. Kai/C18-5d will probably get a texture revamp. I used to think that more methane in an atmosphere would lead to a purple hue, but in reality, it'll just be deeper and deeper blue, so I'll probably change it to an indigo color. It too is hot enough for sulfide/chloride clouds; right now it has faint bands and a mostly uniform purple color. Karkinos/C18-5b is basically done. I just need to get the surface working properly, because for some reason, the surfaces of the planets I make love to break in flight mode. However, the overall texture and the atmosphere are both finalized. Karkinos has an equilibrium temperature in the range of 1150-1200 Kelvin, and a substellar point temperature potentially as high as 1500-1600 Kelvin.
  17. This is a planet pack that will include systems that I have found, helped find, or studied from NASA's K2 and TESS missions. The current name is probably going to be replaced with something better; I didn't really know what else to call it as of now. BACKGROUND I've been finding/studying transiting exoplanets using data from the K2 and TESS missions for the last several years now. Both missions looked at thousands upon thousands of stars at a time to search for tiny, periodic dips in starlight caused by orbiting planets passing between their star and our line of sight. The data is publicly available on MAST (Mikulski Archive for Space Telescopes), and I used the program package LcTools to analyze it and search for transiting planet candidates. Me and several other citizen scientists found quite a lot in K2 data on the Zoonivese project Exoplanet Explorers back in 2017-18, and I've been studying TESS data since late 2018. I helped with the discovery of TOI-700d, the first small habitable zone planet from TESS; TOI-451, a 3-planet system in the 125 million year old Pisces-Eridanus stream; and LTT 1445Ac, an Earth-sized planet in a nearby triple star system. Over most of the year, I've gone back through K2 Campaigns 13, 14, 15, 16, 17, and 18 to record all possible planet candidates and refine their parameters to the best of my ability. MOD ADDITIONS This pack will include many of the systems I have found and studied (but not all of them, because single planet systems with a hot sub-Neptune aren't very interesting). All systems will be scaled-down to KSP scale (1/10th the radius, 1/100th the mass, 1/10th the orbital distance) and will be three orders of magnitude closer to the Kerbol system than they are in real life. Most of the systems from my K2 surveys are hundreds of parsecs away; even 1/100th scale would be too far. With the exception of some TESS planets, the masses and compositions will be hypothetical, but are calculated to be as realistic as possible given what is known about these worlds. Most of these planets are unconfirmed, and it's possible that some might be determined to be false positives in later analysis. If that happens, I will still keep the planets in the mod, but it will be in the flavor text that the planet is a false positive. For the first updates, I will only be adding and working on systems from my K2 surveys. TESS systems and other Exoplanet Explorers systems will come later. There will also be hypothetical moons added to many planets to make the systems more interesting and rewarding to explore.

  18. Liolan (Tau Ceti f) really needs to be puffed up. There's no need to alter any of the other planets; I really like the variety of compositions for the <2 Earth mass planets. Maybe there could be some more Super-Earths, Mega-Earths, and Mini-Neptunes in the 1.5-2.5 Earth radius range for future systems for variety? They would be a lot more difficult to land on or take off from, but if they're far enough from the star, there's opportunity for a lot of big moons. Although if I ever publish a planet pack with a bunch of systems from my K2 Campaigns 13-18 survey, there'll be no shortage of 1.5-2.5 Re planets lol. At least 60% of the planets from just Campaigns 16, 17, and 18 are in that size range, and while I haven't finished refining parameters for the other three Campaigns' candidates, the percentage of 1.5-2.5 Re planets appears to be a little higher. There are even a couple of planets that are decent candidates for being Mega-Earths.
  19. Here are a bunch of the GU objects above 0.85x Earth radius on the exoplanet mass-radius relationship diagram. Smaller planets won't fit, and I didn't include the TRAPPIST analogue planets because their real-life counterparts have already been plotted on such diagrams. Also, the 0.9-1.1x Earth radius section is way too crowded. All planets were converted up to IRL scale (10x the radius and 100x the mass). Teeb, Tide, Infurus, Atlas, Phobor, and Liolan are all >50% iron by mass and are technically iron planets. Teec, Blalo, Narath, Kaith, Eolus, Sicar, and Aquel have a relatively Earth-like mix of silicates and iron.
  20. Are you planning to add analogues of the other potential planets around your Tau Ceti interpretation? While only 4 are confirmed so far, a couple of recent studies have brought up the possibility of a Jupiter analogue, another planet in the HZ, and the original three inner candidates actually being real. A 2018/19 study using Gaia astrometric data (Kervella et al) noticed a shift of around 11.3 m/s, which could be from a Jovian-mass planet (1-2 Mj) in an orbit anywhere from 3 AU to 20 AU from the star. Unfortunately, that's as much constraint as they were able to obtain, which isn't much. Since the debris disk is roughly between 6.2 AU and 52 AU (with a high amount of uncertainty), I would have to guess that either this "Tau Ceti i" orbits around 3-6 AU and closer than the inner limit of the disk, or it orbits further out and has carved a so-far unseen gap. A more recent study, Dietrich and Apai 2020, used the DYNAMITE algorithm to explore the architecture of the Tau Ceti system. DYNAMITE takes into account exoplanet population statistics and information of the target system to predict the orbits of additional planets, and has been used successfully on a few dozen TESS systems by the same authors of this paper. When taking into account the orbits of Tau Ceti g, h, e, and f, DYNAMITE predicts three additional planets, which correlate with the Tau Ceti b, c, and d signals from Tuomi et al 2013. While Feng et al 2017 could not confirm those signals and found a multitude of problems with them, this study provides statistical support that they could exist. Additionally, DYNAMITE predicted PxP-4, the planet you based Aquel on (which I originally thought was a best-case-scenario version of Tau Ceti e until scrolling up a bit). Another thing worth noting is the potential compositions of the Tau Ceti planets. D&A20 mentioned that planets at the orbits of Tau Ceti b, g, and c receive enough radiation that their original hydrogen atmospheres were likely eroded away billions of years ago. However, starting at Tau Ceti h, the insolation from the host star isn't quite enough to have destroyed these original H/He envelopes, so it's a coin toss as to whether or not they're rocky, especially with their true masses likely being in the range of 4-7 Me. I would like to point out that Tau Ceti is quite a metal-poor star, and similarly metal-poor stars appear more likely to host large rocky planets (exceeding 1.6 Re or 6 Me). A couple examples include LHS 1140 and HD 48611 (TOI-214). The theory is that the protoplanets around metal-poor stars take longer to form, so by the time they get large enough to accumulate thick H/He layers, the hydrogen gas in the inner part of the disk has been blown away. Also, your Tau Ceti f analogue is ridiculously dense. Like, it's compatible with a composition of 75-80% iron. Is it going to be made "puffier" in the update? A gaseous Sub-Neptune of 6.7 Earth masses should be around 2.35 Re (scaled down to 1,497.185 km for KSP scale).
  21. The latest version works perfectly fine with 1.11.2 for me. My planet pack I was developing in August (I believe KSP was in v1.10) loaded up correctly, I was able to make a new star system without any issues besides me messing up file paths, and even the enormous Galaxies Unbound mod worked. Every object and custom orbit icon loaded, and the custom ground scatter worked too. I haven't tried to see if Kittopia still works with 1.11/1.11.2, though.
  22. @R-T-B The planet pack I'm developing ran into an error with 1.10-1. I got a message once the game loaded that "Kopernicus was not able to load the custom planetary system due to an exception in the loading process". Here are all of the recommended log files: https://www.dropbox.com/s/pqau27lp7cfzx6v/Logs-Kopernicus.zip?dl=0 I love how Kopernicus now automatically creates a zip file with a copy of the KSP log file, the planet log files, and ModuleManager.ConfigCache. This is going to make bug reporting far easier. NOTE: all 8 of the terrestrial planets currently lack a color and normal map, and are currently only using a flat height map. This is just the first test to make sure they load in properly. A proper height map will be given to each later on, and I will build the color and normal maps via KittopiaTech (assuming it will work).
  23. As I should've anticipated from the name of the patch, Kopernicus 1.9.1-9 does not work in KSP 1.10.1 (although the Nyan Cat loading screen does). And I had just spent the last hour or so prepping the configs for a system of nine planets I'm working on.
