TheGatesOfLogic. Ah, I see what your saying. I do understand that there are still interactions happening, and in turn scattering, but what I'm still looking for is how insignificant is can get. I'm trying not to sound rude, but there's on thing that comes into my head whenever I think about what you're saying. Think of a hyperbolic orbit. The faster you move, the much less of an impact it has on your trajectory. I understand it still has an impact regardless of how faster you're moving, but I'm looking for the point in which you're moving so fast, it's negligible enough to not even account for. In turn, think of minimizing these changes to your matter string to a point where you practically don't change. Like I said, I understand that interactions will happen regardless. I do get what you're saying, though. Truly. As for your point of dilation, that is still theoretical, and does not ignore a relative cosmic speed limit (A bit confusing word choice, but hopefully it still makes sense), so I'm sorry to say I cannot take that into account. I do hope you understand.

No one, Honestly I'm not sure if there is a more straightforward answer. ThatGatesofLogic. I'm not sure what you're referring to when you brought up relativity. Are you meaning the Earth's orbital velocity and your speed are your reference frames? Because I'm taking Earth as a central reference frame, and moving relative to it at this ungodly speed. WestAir... Well, that makes sense. Now that I think more about it, Earth's convection would be involved as well, but that stuff's too complicated for now. Vanamonde, I'm still trying to find what that speed is. My closest guess right now is c(1.141636 x 10^360) That number seem familiar? Really it's just an estimate. Ralathon. I would imagine you would be interacting, but maybe I did misspeak a little. I was honestly referring to if they had time to effect each other so much that you would stop. I guess I said interacting and meant reacting. Sorry for that. KSK. You can think of them like a repulsive magnet inside an attracting magnet. Bring another one in close, and it will stay a very close distance, but never touch. Sure, they are interacting, but they aren't touching, if by touching you mean coming in absolute contact. Neutrinos are a valid comparison, but aren't tangential to what I'm referring to, as their interaction are enough to redirect their momentum. (Brownian motion, is it?) Magnemoe. Ahh darn, ye caught me. Yes, that's how this question came to my mind. I started wondering about what the real world speed to do this would be. I do get what you mean about Kerbin, though. The game is constantly accounting for frame differences, when you can't do that in real life. YNM. A photon (If that's what you mean) could pass into Earth, but not likely out. It would lose all of it's energy fairly fast actually. Lajoswinkler, the reason an object gets hot is because the transferal of energy from one object to the next. I know I said we would be ignoring the light speed limit for now, but it would make sense to assume that this energy transferal happens slower than light, and rather at the speed of sound (As compression waves travel through solids at the speed of sound, so does energy). This reaction probably wouldn't happen fast enough to keep up with you. The end result in this scenario would be you produce enough kinetic energy to destroy the Earth, but I'm still not sure if that would be the case. (There is my theory of Verteron space, but I'll admit, I was out of it last night.) Bobnova. I'm afraid the context and layout of your reply eludes me. Cantab. I much approve of black holes. Oh right, the answer. The first answer is very valid. A way of eluding the context of the question without breaking any rules. I'll do a quick review later to verify if any reactions are made, if any at all. As for the second answer, I took a quick look at that page, and I don't see how that comparison is relevant to the question. Sure, it's about an object flying to the Earth at ridiculous speeds, but this question ignores that. The third answer, A denser object would likely be able to pass through, but will cause masses of interactions in the process. The last answer, Another valid answer. You could quantum tunnel to the other side while keeping the context of the question, but the scales and probabilities of that happening are so low, it probably wont even be worth discussing in the next lifetime (Not meaning to start anything about that.) All in all, very good answers! It seems I have some work of my own to do, but I'll do that later.

There is another option. When you fly, hit F5 to quicksave, then turn the game off. If the tracking station does not work for you, then put something on the launch pad, and hit F9 to load that quicksave.

Engine efficiency ranks by a number of things: Where you want to use it, your scenario, and your time table. To lift your rocket, use the highest amount of thrust you can, and save the better ISP engines for upper stages. To get the most efficiency out of your lifting engines, try launching asparagus style. For space travel, I highly recommend using the nuclear rocket. The poodle is, of course, more powerful, but how far does that go? Of course you'll lose more power in a 390 ISP engine than an 800 ISP engine, so using the nuclear rocket get's you more Delta-V. If your going somewhere nearby, though, it doesn't matter much, but make sure to maximize fuel efficiency either way, just so you don't lose any precious Delta-V. If you need to get somewhere shortly, it's almost always the case that you have to dock a separate propulsion system. If you need to go immediately, though, use the more powerful engines for the travelling stage rather than the high ISP, and save those for the last stage. As inefficient as those engines might be, at least try to find the one with the best thrust-to-weight as well as ISP.

Amazing to hear! Welcome to the forums! I wish you the best of times here! Fairly generic introductions aside, to answer your question of rocket efficiency, there are a few things that come into play. Each of these topics have been touched by Claw already, but I can add in a bit more detail. ISP is very dependent on the propulsive element you are using. For example, small Ion engines kind of work in the same context as a particle accelerator, but does have it's differences. These similarities, though, include the method of acceleration and the sheer amount of power required to do it. The reason this is not a powerful engine, however, is because the amount of thrust these particles produce is laughable, due to the mass and energy transferred from them being so small, regardless of being in a decent sized field. It's like a car taking 5.8 hours to make one right turn. However, they are efficient due to the fact that the propellant used transfers all propulsive energy to the probe in question, which allows this so called "probe" to use every ounce of energy this propellant has to offer. I can go into more detail about the chemistry if you want, or I can leave it at this. Chemical rockets are as powerful and inefficient as they are do the fact that a lot of propulsive kinetic is lost in the exhaust. To explain this properly, lets go back to the basics. Specific impulse is describing the efficiency of an engine by referring to the amount of thrust you get from each unit of fuel/energy expended. Or chemically, how much energy is being transferred from one body to the next per unit of energy expended. So chemical rockets do not exploit all the propulsive energy from the fuel as they could, thus must use a very high amount in order to get that sweet thrust we find so appealing. This is why I love the nuclear rocket. Provides a fair amount of thrust while keeping that lovely Delta-V so high. The upside to chemical rockets is their alternator. Chemical rockets are much more complicated than I'm putting down, but that's the basic gist. And greetings again!

So, a question came up in my head today that I haven't been able to accurately answer, and is a pretty far-fetched question. First of all, rules. On this topic, we will ignore the speed of light being the cosmic speed limit. We will also be ignoring things such as gravitational tidal effects and spaghetiffication. Now, here's the question: If an object were travelling fast enough.. in fact, so fast, that the atoms don't even have time to recognize and react to one another, could passing through a solid body of matter be possible? I mean, it makes sense. The atoms in a body of matter never touch each other. They can get ever so close, but the repulsive forces of their own power and magnetic properties are enough to keep them apart. If you were to keep the atoms in one body of matter from reacting with the atoms in another body, theoretically they should be able to pass through each other without even interacting at all. In fact, you could make a valid comparison by using a very old, fairly sparse theory. Compare this to a hyperbolic orbit while moving at plex-warp speeds, but not in our space. Say, you were to move the speed of light in Verteron space (A theory of my own suggestion that the space we live in is small, and we can gain access to a bigger space, effectively being able to move much greater distances without moving any faster. Still under development, and far beyond our capability to test it.) Anyway, moving the speed of light here could move you vaster distances without compressing space, moving faster, but still interacting with our space. If moving fast enough, indeed, can you pass through a planet? Does this make sense to anyone else, or am I missing something? Keep in mind, we are not here to discuss why this wouldn't be possible. Just would it happen if it could.

It is fairly efficient, as it's specific impulses are balanced, so it is versatile. On a space plane, it can be used for a gliding assist and landing assist. On a rocket, it is typically used on landers, but can be used as a lightweight lifter. On a rocket, I highly recommend the nuclear engine over all else as an upper stage.

Well, in that case, welcome to the forums! Ever imagine you can have all the snacks you want? Well, we have plenty space goodies here! (In other words, hope you have the best of times here!)

And hello to you to, zekes! I am enjoying the forums, and I've barely started! That says a lot for our future.

You know what? I'm pretty sure it is. Let's go with that.

Alright! After a long, super tedious process of micromanaging, simulating, and messing around with maneuver nodes, we finally completed our mission! Here's some shots I took along the way: After some time spent off camera roving around and collecting some science, we head back to the spacecraft that made it all possible, and set a maneuver to return to Kerbin! Many of you might be wondering why I didn't pick up the rover, and that is because of 2 reasons: 1. This isn't a lander, and is equipped with neither the gear, nor delta-v to land and retrieve it. 2. Although it is actually possible to hover above the surface and pick it up, as I do know a very efficient route to take, we would miss our launch window, and run the risk of messing it up. After completing our maneuver, it is time to say goodbye to Duna and Ike. But hey, look at the bright side: I left the rover, so eventually we'll have to send out a retrieval mission! It's like a planned it all along... (Or perhaps it's just something I observed after doing a bit of math and realizing I couldn't go back for it, but let's pretend I planned it all out beforehand just so I don't look like I have no idea how to play this game.) A fair amount of time has passed, and we are at a position well suited for a Kerbin encounter. If we weren't running low on Delta-v, this would actually be a great time to go to Moho. But alas, we do not have infinite delta-v. As we've entered the sphere of influence, we can see Kerbin far off in the distance. We're going a little fast for a landing... (Okay, far too fast) Better start up those engines! A bit of a hitch in the plan, here. I'm well out of fuel! Well darn. Guess monopropellant is my only option, so we'll roll with it. This'll be a while, though... After an absurdly long time spent holding the H key, I noticed we can go to the Mun. I spent a lot of monopropellant trying to avoid the encounter, thinking it would throw us our of proportion. After considering our options, though, I realized it might actually help us... And sure enough, I was right! This maneuver has kicked our periapsis below 70 kilometres, and we are set up for a relatively aggressive aerobreaking maneuver, which will surely take several passes, so I'll be right back... Needless to say I was here for a long time... Well, at least we're guaranteed to get back now. ...by which I mean landing in the water, apparently. Oh well, nothing exploded, so that's a step up. So yeah. My second mission, I'd say was successful, especially now that we get to go back to Duna to get our rover. I just love how Duna looks, regardless of being there only one time. That says a lot for what's left in stock!

Oh crap. I'm sorry, everyone! I promised the Duna mission would be completed today and I nearly forgot! I'll have my souvenir pictures posted here soon, them move on to another mission, which will be in an entirely new thread, and my logbook. Check back very soon for the mission results!

Addicted to typing? Mario's head has gone too far.

The Duna mission is complete! Well, not exactly, we haven't made it back, but we've dropped the rover onto the surface, and have achieved a stable orbit with our capsule! I'll put the rest of this mission on hold for now, but we'll continue... sometime. Most likely tomorrow. I've got a few pictures from the mission. Here's our rocket in the construction hangar: I don't know the scaling of pictures on the website, so sorry if this ends of a little big or small... Yeah, we ain't doing any of that docking halabu! (New vocabulary I invented) We're going straight for Duna, right out of the hangar! Turns out I went at a pretty bad time! Maybe I should have spent some time to dock... oh well. I'll figure something out... If you're wondering about the Kethane symbol at the top, I'm not the only one who plays Kerbal space in this computer, and they got the Kethane mod apparently. After a bit of playing around with maneuvers, we managed to get a decent encounter. Took me nearly 17 minutes to get this right. We're near our encounter node, and turns out we can see Duna, and all her beauty from this far away. Let's take a moment to appreciate this sight... We've hit out encounter, and had the Delta-V to get into an orbit, but let's take it one step further... Let's de-orbit ourselves! You probably think I'm crazy, since this isn't a lander, but refer back to the first image, and it'll all make sense. What's that extra orbit, you say? That is our rover! It's been hitching a ride with us all along! We've air-dropped it, and kicked ourselves back into orbit. And here it is landed! I call this the unflippable rover! This is why I got infernal robotics. I attached the wheels to IR Rotatrons, so if it flips over, the bottom becomes the top! It's not a perfect rover, but it is stable and has all the science you need. So yeah, that's my second mission. Let me know what you think about it, and let me know what planet/moon to go to next!

Fairly interesting challenge. I'll have to try that out sometime. Maybe a Tylo lander? Hmm... or Eve. I'll have to look into that.

Alright. So I have suggestions for Duna (not directly, but I just want an excuse to go), and Dres. Why don't I do both? It'd be fun. I'll upload some pictures of the mission later! I might try Moho as well, but I'll think about that. I should also mention I went ahead and got Infernal Robotics, because it looks extremely useful.

As you probably just saw, Salutations! I'm fairly new to kerbal space, and decided this was the place I would start. I'm starting a mission to the Mun as a first right now, and may get to a planet later. Since I have real world knowledge of spacial mechanics and rocket science, I think this game should be relatively easy. Any recommendations for a first planet to go to? Well, other than that, glad to be here!

What's up, Tricksterzzzz? (That plural, or just you? Nevermind, I'm just being silly.) I'm fairly new to kerbal space as well, but do have experience in real world subjects that this game deals with. You said you were starting your first mission tomorrow? Can't wait for those images! It's always exciting to watch progress and achievements, even if they aren't mine (Hence Scott Manley). If there's anything I can ever do to help you with the game, just ask me. Gotta get that sweet, sweet science after all! (I know a simple "welcome to the forums" would have been sufficient, but... I don't really have the grounds to say that.)

This would work in theory. In the context of Kerbal space, however, it wouldn't. Assuming it works up to its' original expectations, this would be entirely possible. The only problem though is the amount of negative energy you must produce (well, more like extract).
