Pebbles

That was the friend who introduced me to KSP in the first place I myself am a relative child, I've only been around since 0.19

Further Studies. Okay so I tried some additional stuff about how kerbins oceans work, Ultimately my experiments created more questions than they answered... Dose kerbins atmosphere have density? The easiest way to answer this is to ask "Can you have negative mass in KSP?" And following "Do things with no mass or negative mass float away in KSP?" To answer this question I created a New element with a Minus Value for density... Now in my mind this could cause 1 of 2 things. 1: Crash my game and wreck my save 2: Create mass effect technology. As such I called the new element "eezo" After Element Zero. I then modded the element into a fuel tank and loaded it into my game. It didn't crash my game and the game dose seem to recognise that the element would subtract mass, at the mass listed there is The negative value of the Eezo minus the positive weight of the tank. registering the tank as having minus 7 tons of mass. So I put it on a craft as you see, and watched the results. NOTHING HAPPENED!! Aww... I was hoping to "fall" upwards into space. spinning the pod had no special results... So I took this to it's logical conclusion. Again nothing happened... The engine didn't generate sufficient TWR to lift off. Those Eezo tanks clearly have POSITIVE mass. A final experiment. I played around with Mechjeb to see what it had to say. Mechjeb suggested that negative mass craft have negative TWR and negative delta V. So part of me wounders if the game handles negative integers like positive ones... Kinda like with my previous mission the altimeter counted upwards the LOWER I got in the ocean. One final Experiment. This craft was perfectly balanced to have Zero mass... If something this big truly did have No mass then RCS ought to be able to lift it, Mechjeb had kittens at first saying it had some insane amount of delta V. the reason why the value is slightly negative is because the more mono-propellant you use the "lighter" you become making you Negative as you started at 0... Ultimately this thing wasn't able to take off, implying that some part of the engine reads the value as positive but other bits accept the negative value. ----- I'm going to move away from this topic for now I might revisit what's happening here later. Next... Prototype submarines. My hypothesis based on my experiments from my first mission is that KSP has buoyancy roughly similar as we understand it in our world and that everything Kerbal made is positively buoyant. However my super-dense material Neutroniumâ„¢ is infact negatively buoyant. Using this we can build a prototype submarine consisting of a supply of Neutroniumâ„¢ and some other mundane kerbal element. (Liquid fuel in this case) And two vents one that Vents Neutroniumâ„¢ and one that Vents Liquid fuel. Thus regulating the buoyancy of the craft. Behold! Of the engines on top, Both are Turbojet engines, but one uses Neutroniumâ„¢ The other uses Liquid fuel, Of course they also need Intake Air, Which I won't provide because I just want rid of the fuel I don't want thrust. WHOOOSSSHH FLOOFFF PLOP!!! Like before after hitting the water I fell into a dive but rather than ride it out I switched on the Neutroniumâ„¢ pump and sure enough my dive began to stabilize and I reached equilibrium at 103meters Making myself Neutrally buoyant. with 26.8units of ballast and 150units of Liquid fuel. I vented abit more Ballast to make myself surface I began to rise, however I stopped rising at 3 meters beneath the surface. I vented a tiny amount more but I wouldn't easily rise. maybe the top 3 meters has different density? Now for the final stage of my experiment I would vent my positive ballast (My liquid fuel) and I theory I ought to sink again. However... It didn't happen. I vented ALL of my liquid fuel and I actually rose HIGHER in the water. Cresting my top "Vent\Engine" Now this is unusual... all of my previous testing suggested that liquid fuel was a positively buoyant material (rockomax tanks full of liquid fuel only float.) This suggests to me that my hypothesis might be wrong... Maybe there isn't any force of buoyancy at all? Another possibility for this is that a hither to unexplained force pushes anything in water upwards sharply with a strong force, simulating buoyancy, this force acts over the entire surface area of the object, so very large heavy objects like rockomax tanks, float as a result of there surface area, Whereas my probes are extremely small and heavy(over 35tons), with very little surface area, as such it can overwhelm this mysterious "uplift" force of the ocean... I need to perform further testing to be sure but this looks likely which might put a dampener on submarines... Aswell as warp drive... I do enjoy this it's like begin one of the old scientists like newton or Galileo where you have to piece together how the universe works, Often making gross misunderstandings on the way. Like, In the really early versions of KSP before map view it was argued that kerbin was flat. Then someone demonstrated that you could get into orbit and they worked out an orbital parameter table.

Hmm Good questions... TO THE SCIENCE MACHINE!!! Both of these were experiments I planned to investigate at some other time but seeing as you actually asked the question I can bump them up the schedule. Watch this SSSSPAAACCEEEE!!!

Howdy folks pebbles here, For my first mission report, While in space assembly of my space station is continuing at a respectable pace after it's obliteration, It's a good time to goof around and experiment, I know a fair bit about space but I know very little about the ocean. And Why not, The oceans of Kerbin are NOT water. *Everything* of Kerbal design is positively buoyant I tested this by throwing stuff into the ocean, Giant tanks filled with various resources Monoprop, Liquid Fuel, Solid Fuel, command pods ect... All float. Because they are all less dense than the "!Water" Looking at the ResourcesGeneric.CFG of the game you can see the densities of the various elements. Densities are listed as 1X (Liter)=Y (Tons) So we need something heavier than Solid fuel, which I confirmed floats. Assuming Oxidizer is Liquid O2 We guess it's Atomic weight is 32, So Lets work with Mercury instead... Mercury has an atomic weight of 200, 200/32= 6.25 X 0.005 = 0.03125 Lets Add that. { name = Mercury density = 0.03125 flowMode = ALL_VESSEL transfer = PUMP } Now I simply create a Mod Part a fuel tank that contains this instead of Fuel or whatever... (I choose the toroidal fuel tank with 30L of the stuff) Remember it's a Misnomer to presume a bigger tank is better, Either an element contributes negative buoyancy or it doesn't, If it dose then volume is only necessary to overcome the buoyancy of other elements in the craft. Hence why Fat people float better than skinny people. Despite fat people begin more massive. Annddd!!! Nope! Still a floater!!! I mean wowsa... This stuff is Viscous, I guess in the Kerbal universe Blood isn't thicker than water... Nothing is thicker than water not even Osmium. Although this dose explain why kerbin a planet 1/10th the size of earth gains its mass to have 1G Gravity. Also Explains why there are no clouds or hydrological sphere at all, You'd need to heat this stuff upto thousands of degrees to vaporize it and if it moved, through a river it would obliterate any land mass it passed over. SEE WE'RE LEARNING STUFF! Anyway, Continuing on, unfortunately there aren't many normal elements denser, Osmium which I mentioned and perhaps some Lanthanide's Depleted Uranium ect... But rather than faff around lets really crank it up. It's not actually Neutronium, That would break anything I loaded it onto. It has a Density of 1.2Tons per Liter, Which is close to non-Collapsed Stellar Core material. And ignore that to the side for now, That comes later. firstly I need to Put this on a Rover and drive it into the sea to see if I sink and can drive around the bottom. CRUNCH!!!! Yeah I know I know... Need moar struts... Driving this thing reminds me of the time I used to be fat. You don't feel it until you move with momentum, like riding your bicycle for the first time in years after getting fat. EAT SCIENCE OCEAN NOW YOU WILL BE CRUSHED BY MY FAT ASS!!! HAHAHAHA!!! Yeah I am underwater it just doesn't render waters surface from the underside :/ Well I thought that anyway, I tried to drive forward, But as soon as I apply inertia the wheels which are buoyant lift up and the thing flips over... Oh well those kerbals needed a wash anyway they never change there spacesuits. Normally I would consider adding RCS or rocket motors for propulsion but it weighs over 39tons it wouldn't even nudge it, Besides too much fuel is Positive buoyancy. NEXT EXPERIMENT!!! This is what you saw in a previous picture, A probe weighted with 30L of Neutronium Attached to an "S-1 Rocket" S-1 is my "serious business rocket," Normally I'm a gal who's partial to a good scramjet or a well placed Nerva... But I accept that Liquid Fuel rockets have there place. This is for firing 35ton masses (Corvette Class vessels) into Orbit. We're not taking it to orbit today, Suborbital will do. The Engines are to slow it's decent prior to the Chutes fully opening otherwise the abrupt change in momentum rips the probe apart. There positioned up like that because the Neutronium is positioned towards the top and it will flip, Torque is not really happening with the final stage (note you can see islands in the background because I had to relaunch it I fired the retros prematurely and it broke apart first time) WHOOOSSSHH!!! OH YEAH!!! YEA... Oh it broke... It's okay the decoupler just snapped off when the mainsail cut out, the snap was too much for it. Had to decouple it manually. Drouges Deployed now FIRE RETROS!!! FOR DEAR LIFE!!! FIRE!! Brace for impact!!! Systems intact! Decent confirmed 0.3m/s I've placed the instruments on the topside of the probe(under the decoupler), My experiment with the rover showed the Camera hates your guts if you go underwater. Chase Cam is the only camera angle that lets you move at all. Helpfully the Altimeter counts upwards the deeper we go. Telemetry is as follows.

See you next mission. Oh go on then one last photo, Jeb was busy upstairs while I was doing this building the space station, He caught this nice pic of kerbin from his Spaceplane.
