Get some wide, white, shallow containers, fill them with water and leave them around the yard. If there are cats around, put them on an elevated position. Be sure to change the water daily. Birds will appreciate it.

Tiny? It's big, 2.5 m one. KSPX mod. -
No RF port? The manufacturer must be a moron. You don't just dump such an important thing. Buy a better TV receiver that has both RF and digital input ports. Also, what is a "NES 2"? Are you referring to the SNES? NES SNES

Most of the surface, if not all of it (perhaps the mountain tops aren't) is immersed in a supercritical fluid carbon(IV) oxide. Blimping around is hypothetically possible. Why is that? Indeed, that's about the correct temperature.

lajoswinkler replied to Felger's topic in KSP1 Mod Releases
Oh, there! LOL Thanks. edit: maybe it should be noted in the first post that the only way to set the particles would be installing the toolbar mod, because other than that, you can't access smokescreen's properties. I've spent an hour trying to figure this out. edit2: If this could do this it would be so cool. -

That means that, properly shielded, they would work for a longer time. This is what I find most interesting about designing a related rover/probe: NASA, understandably, wants to minimize the amount of electronics that need to be actively cooled on any Venus lander, because keeping things cool on the surface of Venus is going to suck down a massive amount of power. Photovoltaics won’t really work under all those clouds. But one slightly counterintuitive option might be a cooling system powered by a Stirling engine, which depends on the rover generating as much heat as it possibly can. Stirling engines convert a heat differential into mechanical energy, so the idea is that you’d bottle up a bunch of plutonium-238, which would heat itself to 1,200 °C through radioactive decay. With one side of a Stirling engine acting as a heat sink for the plutonium and the other side exposed to the comparatively frigid Venutian atmosphere, a Stirling engine could generate several hundred watts of powerâ€â€enough to keep the electronics of a well insulated rover under 300 °C. Exact same thing I've been talking about. To cool it down, you need to heat one part of the system way up. This would work for a long time, if the Stirling engine is well made. The probe would be refrigerated to 200-250 °C by using the heat flow (therefore work) from a very hot first tank to the heatsink which is Venusian atmosphere. We might land a rover there sooner than we thought.

[1.12.x] Heat Control - More radiators! (August 18, 2024)
lajoswinkler replied to Nertea's topic in KSP1 Mod Releases
Nertea, here's a suggestion. Active cooling using stuff like LiquidNitrogen resource that the user would use only in the worst conditions to remove the heat for a short amount of time. Same resource could be packed into an EVA item for KIS, just like there's an EVA propellant bottle you can see here. It would enable Kerbals to go on EVA closer to Kerbol (example: Ablate from Kragrathea's Planet Factory, where they die in less than 30 seconds) for a few minutes. -

Is there a way to counteract Smoke Screen's gobbling of the framerate? I get massive performance degradation if my view is from up close. It's nothing new. Smoke Screen was doing this a long time ago. For example this is about the closest I can get without getting <10 fps. It looks so nice, but if there isn't anything I can do, I won't be able to use the mod. :/ -
I know the required delta v. It's over 20 km/s and less than 20.5 km/s. I've confirmed that a long time ago. That is a problem, though. It's the requirement to get from Kerbin to low Ablate orbit. But Kron 5 needs to return home, and that's where the main issue is. What will it be? 35 km/s in total? I'm not even sure if I will be able to use a Taurus HCV capsule. This is a fantastic amount of delta v. Maybe if I send resupply tanks, maybe... Catching Ablate will not be possible by falling from Kerbin. Deceleration would have to be stupidly high. I mean, the thing flew by like a rock thrown at the probe. Last time I went to Ablate, it had to be done from an orbit lower than Moho's.
-
Ikar 1 made a scary close flyby of Ablate which was arranged at Kerbin's orbit. This all happened in less than 4 seconds, so there wasn't even time for proper terrain loading. The probe found that the thermal equilibrium is established at no less than 1250 K. Several instruments exploded. Next probe, Ikar 2, will try to enter into orbit around Ablate and measure other qualities, including the equilibrium temperature in Ablate's shade.

KSPX also has engines that could use this. http://forum.kerbalspaceprogram.com/threads/107047-1-0-x-KSPX-Kerbal-Stock-Part-eXpansion-mod-reposted-v0-2-9-11-05-15 -
Yes, it is back. Poland and Croatia in red. *adds more ice*

Oxygen content in water/ water breathing.
lajoswinkler replied to magnemoe's topic in Science & Spaceflight
Fish have a different physiology than mammals. They are cold blooded and thus don't require that much oxygen. Everything, including their relatively stupid brains compared to the most primitive mammal, gets enough oxygen by taking over oxygen dissolved in water. If you want your body to be heated up all the time, if you want to run and to think a lot, you need more oxygen. Evolutionary standpoint. Breathing in fluorinated hydrocarbons with dissolved oxygen inside is not a new thing, but not much has been done since the first experiments. It is not a benign process. Alveolar damage occurs and you get blood in the exhaled liquid. -
It does not hint at ice. Traces of gaseous water are almost certainly coming out of the hole, but ice is an ephemeral thing on the surface of Ceres. It will quickly sublimate. These must be salty deposits that have accumulated there over the eons of very mild puffing. Obviously there's something churning inside that rarely comes out as very rarified puff of salt particles, perhaps some water ice particles and of course gaseous water. Water ice sublimates away in a matter of weeks at most, water gas dissipates, being pushed by the solar wind. It has to be very mild and it has to be traces, because Ceres is so old. Anything fast enough to impress us in a few months is not a sustainable process in the terms of billions of years. BTW here are the synthesized images with the very important caption writing on them. 5x vertical exaggerated CGI height maps with actual photographs pasted on top of it.

Planet Factory CE is not the mod being resurrected. "The" mod, the original Krag's mod was Planet Factory. It had pretty well rendered stuff, but the models in the map views were goofy and highly approximate. The screenshot I took back then was taken with maximum details turned on. Nothing was wrong with my installation.
-
Hm, back then I got this picture by zooming out from the vessel as much as I could. I think. Try to do that and see if they're the same. The weird looking Ablate from the map view was not Krag's intention. It was a remnant, and the thing you see here is how it looked like for real. I'm not sure how did you get this PlanetFactory Ablate pqs view to look like that.

Quantum phenomena such as the one described humorously in that thought experiment are not applied to such macroscopic systems. If the reflectivity of the insides is perfect (albedo 100%), nothing would change. Of course, such surface can not exist because it would violate the basic laws of nature. Every photon bumping into atom, getting absorbed and then spitted out when the atom relaxes is subjected to energy conversion and that is never 100% efficient.

Rosetta, Philae and Comet 67P/Churyumov-Gerasimenko.
lajoswinkler replied to Vicomt's topic in Science & Spaceflight
ESA mentions possible change in orientation. Nothing about certain blowing off from the surface. -
If the reflection is perfect, it would keep bouncing, but as there are no such things as 100% efficient energy transfers, it would be quickly consumed on heating up the ball material.

Bob has sampled the crater floor and has returned to the landing site. He has spent his entire EVA propellant tank, too. A nap had to be taken until the ship was in the correct position. And in the morning, back to the ship.

[1.12.x] Heat Control - More radiators! (August 18, 2024)
lajoswinkler replied to Nertea's topic in KSP1 Mod Releases
Anxiously waiting for this mod to get to v1.0.4. -
We had at least one example where physicists were tricked into giving interviews which were manipulated. Their sentences would be taken out of context to make a profitable franchise for the gullible and ignorant people. So I've finished watching this documentary from the opening post and sadly, it still makes one huge mistake. Popular science educators, especially if they are physicists, seem to forget how the average Joe thinks and what's more disturbing, aren't aware of the fact this average Joe's mind has been contaminated with quantum mysticism lies which have turned into a meme that has been spread everywhere by the ever growing Internet. To specify - the observer effect. The key misunderstanding that quacks exploit for explaining their miracle cures, prayers, chants, pendulums, etc., is that the observer means a living person, a consciousness. If it takes that, then there's a "soul". Woo woo, cue the mysterious music... or Enya. That is a huge, fat, greasy lie. Observing means taking a measurement, and not only machines can do it, but they actually do it. They must do it because we're too big, clumsy, massive, unresposive and with pathetic receptor units. The act of measurement is just that. It does not require a person. Just an interference with the system done by just about anything used. Quacks use those greasy fat lies to back up their claims about "souls" and "claivoyance", "levitation" and whatnot. This single thing is the power source of a global confusion which has enormous negative consequences on the modern society which, if wants to go forward, simply must be educated about the basis of the artificial world it has built. It powers "The Secret", it powers the whole New Age movement. So much damage has been done by essentially producing a new global cult that stomps over science. Sadly, this hasn't been tackled in this documentary, only barely hinted in one sentence. That only makes it more fuzzy and opens more possibilities for unsuspecting laymen to get fooled and their brains cemented with pseudoscience. Scientists simply must start acknowledging these problems. After all, it's that pile of laymen that brings in the cash and might one day barge into the lab like an angry mob.
