This is very similar to "we need to have propellers" thread. While I agree that building submarine is fun, it's highly unlikely that there'll be a stock submarine parts. The main issue is the very niche usage (only on 3 planets) and general difficulty in maneuvering underwater (water is ridiculously dense in KSP). Only 1 mod that I've known having a ocean-related science exploration instrument based on depth (Dmagic). You don't need a stock propeller, there's already one, see that high bypass turbofan? Goliath? Set it to reverse thrust and put it behind as an impromptu ducted propeller. People has been building submarines using ore tanks and jet engines and for some people, jury-rigging a submarine from rocket parts is a lot more fun. Oceans in KSP is basically a splashdown site, and besides, no one in real life has sent any actual submarine (even underwater probes) to another planet

Building a floatplane

Just doing some shenanigan with "speed" and "heat" Without using HRP (Heat Resistant Parts), this craft would've blown up before even leaving 5000m Look at that speed, time of flight and altitude! In orbit flight log concludes that... The G-force of this craft SHOULD make those G-tourists blacked out That's it, test completed. Time to bring those tourists aboard...

If we build a spaceship that's large enough (Like a gigantic mothership-level that measures in kilometers), could the ship being crushed by it's own "gravity"? (How to say this? basically it has enough mass to be "rounded by it's own gravity" and crush the entire ship). If that so, does a Death Star (which is already spherical) could be crushed into smaller sphere in this case?

This looks like 3D version of factorio. Looks interesting, I'll take an interest in this one

I'll share some: 1. Magnetic wheels or tracks that automatically sticks on surface, useful for driving on Gilly or off Mohole 2. Orbital mining beam, basically think your typical ISRU surface base, now put it in orbit, with giant beam emitter that needs a lot more power to operate than drills, but can dismantle planetary regolith from orbit 3. Not exactly a part, but I have an idea of automatic rocketbuilding mod. Basically, on VAB: -Determine destination and whether going back home or not -Input payload mass. The rocket will be built based on bare minimum Dv needed to bring that payload into destination -The mod will automatically build a rocket design that fits the required parameters Limitation: too large payload mass may cause the mod to built a rocket that the computer itself cannot handle, leading to a crash. It also only builds a rocket to go there, without the means to land there (that's your job)

I'm testing a small disposable rocket for quickly putting small satellite in orbit And going underwater

How exactly "flying low to avoid the radar" works? Does it means flying below the height of radar tower itself? To avoid the sweeping beam? If that so, on relatively clear and flat patches of land, such as desert, with no mountains around a very large area, could a radar tower erected lower than usual height to mitigate this tactic?

Jeb has finished his Mun mission, time to go back to Kerbin... Reentry seems normal. Everything looks good... Wait, did I sense something unnatural in my control? OH CRAP! The fuel tank! I accidentally used too much fuel during retrograde burn and now it's deprived of liquid fuel! I can't use oxidizer only for jet engines and now my craft is spinning out of control! Cannot regain the stability! Alternator on engines are non functional! 5000 meters... Ah screw it! EJECT! It pains me to see such a fine craft plummet to it's doom, but for the sake of my crew, I'll do anything to save their life, even if it means the loss of entire craft (Crew safety is my first priority in my space agency, more than the space asset) Jeb returned safely from that mission. The craft is put back into design bureau for redesign to include a bigger fuel tank capacity to prevent the same problem occuring again

Build your completed base in VAB/SPH with this format: - a central core (preferrably the one that acts as control point), that must contain the following: ISRU, fuel tank and engines with enough total Dv for going from LKO to land on minmus (calculation must be done on "complete mass" base configuration, not just central core) - put docking ports in radial symmetry around this central core (preferrably in even numbers), this will be the module "hardpoint") - make a module that'll be connected to the central core. Since it's radial symmetry, make so that each of these contains the remaining parts necessary to make a mining base, that is solar panels, drills, radiators, ore tanks (smallest is enough, it's better to convert ore directly, instead of storing it). In short, makes so that by itself, one symmetry module is inefficient at doing it's job, but with other symmetry modules, it's efficient. Since they are placed in radial symmetry, they'll be balanced. You can add more engines too - if you want to add anything else, add a docking port on top the central core for anything else, such as habitation, antenna, etc. Don't forget to add landing gears on all symmetry modules and central core and make their height fits -launch in this order: central core to LKO, all modules (do it one by one) docking with central core in LKO, then anything else you want to add on top the central core. Do this until the base is complete -now all you need is just burn to minmus and land on it! The used fuel tank in central core now functions as fuel storage from mining

I played using TAC lifesupport, since it's mechanics are rather easy to understand and fairly straightforward (Don't let supplies get to 0, and you're fine). On a side note, I also used it alongside DeepFreeze mod (Aka Kerbal popsicle mod) to put any kerbals into cryosleep (Basically disabling any life support requirement for that kerbal, but also makes them unavailable for use) when I missed the resupply mission launch window or can't be bothered with kerbal's bodily needs when doing interplanetary or stupid shenanigans. It's basically my "off" button (in style) when I'm not really in mood using life support, but too lazy to open the gamedata and delete the mod folder

"People die if they are killed" -Shirou, Fate/Stay Night

On polar region, where the ice sheet's thickness is sufficient for submarines to break through, is it possible for ground forces on the ice sheet to detect submarine lurking beneath the ice sheet by "listening" the ice sheet?

How do kerbals reproduced? Fixed that title for you

Look at the crew selection trailer video for KSP, Jeb's ID code is 0001. This could indicate he's the 1st gen clone

Wanna know? Step 1: Set the game's resolution and graphic options to maximum Step 2: Go to VAB/SPH, select the first part (any part) Step 3: Attach mystery goo canister to it and open it Step 4: If you zoom in REALLY REALLY close to the holes inside the canister, you see "Smiling faces" on each holes Considering the goo reacts to the environment, and how often rescue missions available, I guess the kerbals on Kerbin is spawned from crash landed goo canister (or Wernher von Kerman's experiments), and the kerbals that needs rescue is a remnant from goo canister that's left long enough. Those canisters are actually a cloning machine for Kerbals Or maybe they're just Space Krakens in disguise. Because if you apply a force powerful enough to stretch the kerbals into sphagettification, they transcends their corporeal form and shows their "true" (glitchy) Kraken form, complete with tentacles (actually an overly stretched head, arms and legs)

My bad, it's the STR-1, not klin-1 (those -1 designation!) But it's true that the design team is recalled for building a prototype robotic vehicle for assisting the cleanup operation. According to the entry in wikipedia about Lunokhod program: "The Lunokhod design returned to limelight 15 years later due to the Chernobyl nuclear power plant disaster on April 26, 1986.The East German-built remote controlled bulldozers available to Soviet civil defense troops weighed dozens of tons – too heavy to operate on the remaining parts of the partially collapsed reactor building roof. Human laborers could not be employed effectively to shovel debris, since work shifts were limited to 90 second intervals due to intense ionizing radiation. Lunokhod designers were called back from retirement, and in two weeks rovers were made which used nuclear decay heat sources for internal rack climate control, their electronic systems were already hardened to partly resist radiation. This benefit allowed the 1986 designers to quickly devise a derived vehicle type for nuclear disaster recovery work. On July 15, two rovers, called STR-1, were delivered to the Chernobyl accident zone and proved useful for clearing debris, earning awards for the designers. Due to extremely high radiation levels, both STR-1 rovers eventually failed, and human workers (later named liquidators) were called in." Way different than klin-1 indeed Also, some more reading about the unmanned vehicles that's used during Chernobyl disaster: https://io9.gizmodo.com/a-museum-of-robotic-equipment-used-during-the-chernobyl-512831778 More about STR-1: http://www.rovercompany.ru/News/New_01.html

The Klin-1 robot that works during the Chernobyl cleanup operation following the reactor explosion is based from Lunokhod rover (since it's already hardened against space radiation). The design team is literally recalled to get a prototype ready as soon as possible to assist the cleanup process

During the Cold War, tensions are increasing between United States and Soviet Union in terms of nuclear weapon capabilities. In the nuke-happy atomic era, where nuclear power seems to be the "universal solution" that can be put anywhere, from mundane nuclear bombs to mineral water (seriously), it doesn't take too long for someone to get an idea to put nuclear reactor into aircraft. The reason? Having a very long operational life and the capability to continuously provide electrical power, a nuclear reactor gives a nuclear bomber practically infinite operational range (KSP mod said that ) so long as it's reactor is still active with very long interval between refueling. Due to the size and mass of the reactor, only heavy strategic bomber can mount them. Not surprisingly, both sides pursued the idea and created their own nuclear-powered aircraft: Soviet Tupolev Tu-96LAL... and Convair NB-36H However, unlike nuclear reactors, which is a static installation where maintenance crew can operate safely with the facilities such as decontamination chamber, sealed room and radiation shielding to prevent radiation from leaking through the environment, a nuclear powered aircraft simply cannot afford such luxury due to the limited load capacity, and installing nuclear reactor maintenance facilities on every airbase simply isn't an appealing option. The maintenance crew of nuclear bomber cannot be compared to regular maintenance crew for conventional aircraft. It's like trying to maintain a flying Chernobyl that isn't nailed down to earth and regularly files above enemy territory where there's always a possibility enemy fighters "ventilating" the reactor vessel. The United States then built a specially made purpose-built nuclear aircraft maintenance vehicle, The Beetle Basically a mecha on treads Built by Jered Industries in Detroit for General Electric’s (ominously named) Nuclear Materials and Propulsion Operation division using the chassis of M-42 Duster anti-air vehicle, the Beetle was a giant mechanical terror as if it's a machine monster straight out of B-movies. Specifically designed for the Air Force Special Weapons Centre, initially to service and maintain a planned fleet of atomic-powered Air Force bombers, it's the only vehicle of it's class. According to declassified Air Force reports, work began on the “mech” in 1959, and it was completed in 1961. The Beetle’s operation was to repair and maintain engines, until the atomic aircraft project was cancelled in 1961. Because the Beetle was first conceived to fix aircraft engines that would be soaked in radiation, it had to be nuclear-proof. Because these would be BIG aircraft, with large parts that were high off the ground, the Beetle had to be big as well. And because the actual duties it was to perform would require a great deal of precision and finesse, the Beetle was given two arms with pincers for “hands”, which is where the “Beetle” name originates. All of which explain why the Beetle was a colossal 19 feet long, 12 feet wide, 11 feet high and weighed a ground-shaking 77 tons. The pilot was shielded by an inch of steel armour on the outside of the unit, half-an-inch inside and a minimum of 12 inches of lead plating around the cabin, which would keep him shielded from all but the most intense blasts of radiation. On top of all that, the cockpit glass was 23 inches thick, and was made up of seven individual panes of leaded glass. To actually drive the Beetle, the pilot couldn’t just pop open a hatch and jump in. The canopy, which weighed 15,000 pounds, had to be raised by hydraulic lifts then lowered onto guidance rods, a process which took several minutes. Once inside, despite cramped conditions, the pilot had some degree of comfort, with a small TV set, air conditioning and even an ashtray, should the stress of dealing with the remains of a nuclear holocaust get a little much from time to time. The Cockpit Powered by a 500hp engine, the Beetle could, on a hard, flat surface, reach a top speed of eight miles per hour. Any faster (not that it could go much faster) and the vibrations damaged some of its finer instrumentation and mechanics. That’s painfully slow, yes, but speed had been traded off for power, the robot’s bulk meaning it had 85,000 pounds of pull in its arms, strong enough to either punch through concrete wall or, should the need arise, tear down buildings. Yet despite this raw power, it could also (thanks to its roots as a servicing platform) perform incredibly delicate operations. At a public demonstration in 1962, for example, the Beetle was able to roll up to a carton of eggs, pick a single egg up and hold it in its pincers without breaking it and even putting the egg on a spoon. A gentle giant indeed In a final and (given the appearance and scale of the Beetle) unexpected twist, the robot was also capable of reaching great heights. The cabin, which housed the cockpit and arms, was able to be raised on four hydraulic pistons, and when fully extended the Beetle stood an imposing 27 feet off the ground, more than high enough to pick through the rubble of a decent-sized apartment building. However, for all its promise and science fiction appeal, the Beetle just didn’t work very well. At the same 1962 demonstration it managed to pick up an egg (for Popular Science and Life magazines) it also, over the source of four days, “operated seldom”, the Beetle plagued by hydraulic leaks, broken arms, dead generators (the cockpit instrumentation had its own engine) and countless short circuits. Internal testing conducted by the Air Force was even more damning, citing constant mechanical failures and an impossibly high standard of maintenance required to keep the Beetle in good working order. Perhaps its biggest failing, however, was that it was utterly unsuitable for active duty. The Beetle had been designed as a maintenance platform, which would operate from the confines and relative safety of an Air Force base. With the demise of the atomic aircraft program, however, the other potential roles planned for it would have required a more active deployment, something its large size, heavy weight, sluggish speed and most crucially unwieldiness (it took several minutes for a pilot to get in and out, which means it has low readiness capability) simply could not stand up to. Future efforts of this type were thus focused on making military robots smaller, both so that they would be lighter (easier to maintain) and also so that they could be operated remotely, rather than having to provide such extreme protection measures for a single pilot. It’s unknown what ultimately became of the Beetle. Maybe it's rusted somewhere, or maybe it's scrapped. The fate of the vehicle is currently unknown.

Probably because they slapped on the inner casing instead of outer casing

You know what? What would happen if suddenly the concept of Coulomb's force disappeared from our universe today?

You can transfer the pics to computer and, if you don't have Photoshop, you can basically: 1. Right-click the image file and select edit (in paint) 2. Ctrl+a to select entire image 3. There should be a menu for resize on the toolbar 4. Mark "maintain aspect ratio" and use "by percentage" to decrease the image's resolution (entering 50 will decrease it's resolution by 50 percent, and that usually reduces A LOT of file size) 5. Save the file

Why the ball-shaped design of reentry capsule in Vostok spacecraft (That carried first man in space) isn't used anymore? Most reentry capsule today seems using the roughly conical design Also, unrelated, but is there any free software to "degrade" the resolution of the video? Like, I had a 720p video that I wanna degrade to 360p?
