    You do not need to adjust the height map directly, nor do you need to blur the normal map. Applying some PQS mods with differing seeds is the only way to get rid of the stepped, pixelated terrain (PQS mods are in the config). The Kopernicus Wiki has descriptions of which PQS mods you can use and how they work. 

    Thanks, this advice is working pretty well so far!

    Oh, by the way, the Pallas analog is coming into fruition now. Its name is Quazen and it's on a highly inclined orbit that may require a Jool assist to even dare to reach.

    Ok I have actually loaded your mod and took a look at the asteroids and it seems that the terrain is a bit...... Stepped, lets just say
    MOQcXpG.png

    Now this can be caused by a number of things, either you image resolution is not high enough , poor blending of the height map, or too high deformity, I will try to fix it for you or you can do it yourself.

    I used a 4096x2048 PNG map for Onor, and 2048x1024 maps for Yuppo considering it's smaller. I think it might have been a problem because my image was in 8-bit RGB color space, and I did try to blur the normal map to get smoother transitions.

    While I do think I know the cause, I don't know how exactly to fix the problem short of adding some slight PQS noise to the heightmap or something. Could you possibly show me how?

    So this is like a little asteroid pack from the looks of it, looks noice
    Tho gotta fix the polar spike on one of the asteroids.

    Also Kop objects can't have their orbits changed.....

    Exactly what I'm doing so far. I've been trying to fix the polar spike lately. And the deorbiting thing would be a thing that could possibly work with Principia.

    Speaking of, here's the link if you want to try it out: Janet's Planets 0.1.0

    Oh hai.

    This is a basic planet pack so far that adds a Near-Kerbin binary asteroid, Doppler-Dyva, a Pallas-like two-toned potato, Quazen, and four binary Jool trojans. Basically asteroids not filled by niches such as Minor Planets Expansion.

    Download here on SpaceDock.

    This was the old picture of Doppler, once named Onor (please don't deadname it). It's a relic of my past and how I've improved.

    Concept for a Jupiter-Saturn-Haumea flyby probe

    Anyway... how will we handle the Jupiter flyby? Saturn? Haumea? Anyone?

    I believe maybe Jupiter could me used as a calibration test for the instruments... maybe also as a guide-star for operations? (no wait... how about Sirius?)

    Saturn would provide nice science opportunities.

    How big of an antenna would it be to receive data rather quickly from astronomical distances?

    Getting a video from Saturn would be hard because of bandwidth, not mass, it would take a long time to transmit, and time is not something an atmospheric probe has a lot of

    Yes. At most, to keep atmospheric data a priority, it could take, maybe... a rather low-resolution picture? And only one? Just to take it? Hopefully in color... :P

    So... yeah. That sound like a good compromise?

    Found better trajectories

    As Saturn is kinda Chronus, the Saturnian descent probe can be Omphalos.

    While the fly-by probe happily escaping Saturn's gravity may be Zeus.
    Also it came from Jupiter (kinda Zeus, too), so it's really-really Zeus.

    A launcher/tug/whatever delivering it, is Rhea (delivered both Zeus and the stone).

    Haumea is (as I can get from wiki) a Hawaian matronal goddess, so in this logical chain it can be associated with any of Zeus's passions or wife Hera.
    But as it doesn't have a probe for Haumea, then no matter.

    Zeus-Omphalos sounds good. It's a shame, though, that 'Oumuamua is taken...

    I love the idea of visual image cameras on the atmospheric probe. For some reason, we have sent multiple probes to gas giants but we have precisely zero imagery from within the atmosphere, even though it ought to be some of the most spectacular views in the system! Bonus points for colour video. I mean, its not like high definition video cameras cant be made extremely tiny for a a handful of grams of mass, I dont see why it could not be done.

    That was kind of the point. :P

    Trajectory - various long range probes have made multiple slingshots around Earth before heading out, it may be possible to extend dV or reduce fuel proportion by taking advantage of this. And the voyager probes (IIRC) utilised a rare alignment of the planets to visit multiple places and gain slingshots around each, it would take careful study and prediction of planetary positions and probably a lot of computation, to find another highly optimised trajectory like that.

    Do you know roughly how long the trip to Haumea could take?

    3

    The trajectory supplied on the Google Drive photo (made by me) suggests it can take anywhere between 16-22 years, depending on launch date and chosen trajectory. I made an estimate of the trajectory based on SpaceEngine photographs, though, so forgive me if not everything is completely correct. :/ Also, given that it is a flyby probe, it doesn't really need much of a huge rocket. I was thinking, lowest-case scenario, Ariane V. However, an Atlas, Delta, Falcon, or even SLS could be used giving further budgeting. I would have done a direct EESh route, but I want to keep the tradition of Jupiter flybys for OSS missions: that's what Trajectory Browser by NASA says would be the quickest path for a flyby probe.

    https://trajbrowser.arc.nasa.gov/traj_browser.php?NEAs=on&NECs=on&chk_maxMag=on&maxMag=25&chk_maxOCC=on&maxOCC=4&chk_target_list=on&target_list=Saturn&mission_class=oneway&mission_type=flyby&LD1=2030&LD2=2040&maxDT=10&DTunit=yrs&maxDV=10&min=DT&wdw_width=365&submit=Search#a_load_results

    With a launch on October 5, 2037 with a dV of 7.94 km/s, and a Jupiter swingby at an altitude of 4.36 RJ  on January 28, 2039, the probe would arrive at Saturn on June 23, 2040, for a total EJS transfer of 2.72 years, instead of the 6 proposed in my initial trajectory. This could cut the transfer time to Haumea by a few years, actually... given this launch date, I would like to see which position for Haumea would be the most optimal for both fuel and time.

    When I modify the trajectory to include this (which probably won't take long) I will post it in both the original post and a new one.

    This has evolved into less a discussion about exploring space and more into what can be flung into it. It's still interesting, but...

    Any concepts for names, maybe, for the probe? Or the atmospheric probe? Modifications we could make to the trajectory to make it less fuel- or time-consuming?

    Don't get me wrong, I'm glad I'm opening discussion about what mementos to send to aliens, but what about the primary mission?

    Given it has RTG anyway why bother with another one.

    ________

     

    I'm still not too convinced with the trajectory so far. Would need one of their extra good simulations.

    What will we carry ? Depends on the size, I think a rad-hardened phone with instructions to assemble the battery and the... screen ? Not sure would it last a million years or not.

    Idk, mine can't run RO/RSS. You could probably see in KSPTOT for the trajectory.

     

    Maybe a super-microscopic etching of certain human images? Or maybe it could come with a large USB drive, with a plug embedded within it?

    Who knows what to bring along?

    (maybe if Mike Brown dies before the launch, his ashes could be transported? just saying)

    A mass of energetic but stable organic compounds to show that we understand chemistry.

    A critical mass of uranium in a sub-critical arrangement to show that we understand nuclear concepts.

    A mass of lithiuim deuteride for ummmm....ummm....ballast?

    All wrapped up in a pure gold, precisely machined container to show that we understand fine machining/metallurgical principles and precise engineering.

    Heh... good idea. :P 

    Certainly helps.

     

    EDIT: A NUKE WOULD NOT HELP A MISSION AT ALL.

    I have been studying concepts for missions, and I think I might have one. It is basically an expansion upon the idea of a Saturn atmospheric probe whose relay will escape the Solar System. As of yet, it is nameless, but I have some ideas for what it will be.

    The carrier-relay probe will have a wide-angle camera with color capabilities, and a narrow-angle camera with only B&W. This is similar to the Ralph-Lorri dichotomy on New Horizons. It may also have some other instruments from the Voyager probes, such as a magnetometer, radio receiver, UV spectrometer, etc. Finally, it will carry an atmospheric probe to descend into Saturn's atmosphere. It will be released not long before the Saturn flyby, and after the relay passes from the shadow, it will relay the data collected from the atmospheric probe, as well as data it may have collected as well.

    The carrier-relay would look like a mesh between Voyager, New Horizons, and Galileo (with the atmospheric probe), possibly.

    It would be launched in mid-2034, have a 1.7-year-long cruise phase to Jupiter, then take about 4 years to get to Saturn. After that, a Haumea flyby may be possible, given enough funding directed toward it.

    A couple of questions, however:

    1. Since it's on an escape trajectory from the Solar System, what cargo will it carry for aliens to find?
    2. Would it be feasible to have a camera embedded into the probe to take a picture of the Saturnian atmosphere?
    3. To get to Haumea, how close would the carrier-relay have to fly to Saturn?
    4. Would it be possible to make a mockup of it using RSS? (preferably both imgur photographs AND a youtube video)

    These are two possible trajectories I might use. They aren't necessary, but is instead a template or guideline.
