This is my submission. Since I still haven't learned how to properly travel to other planets, I'll be on the Hanland side. This ship is a major step forward in cruiser technology. It has a reduced visual profile, making it a harder target to land hits on, yet doesn't sacrifice it's firepower at the same time. On both sides of the ship, there are three rows of 3x stacked projectiles, which mix torpedo and missile designs to make a compact, yet destructive weapon system capable of fighting the largest of ships, even carriers. "This beauty was going to be called the X-Wing, but the legal department said, "Nooooo, we'd have LEGAL issues if we called it that..." Gir Kerbal, Lead Designer Ship- GIR-Tec Havok Cruiser Company- GIR-Tec Company Bio - GIR-Tec is a relatively new ship developer, who are focused on the creation of heavy weapons for use in space. After being turned down by Spiritwolf, since they were aiming for less destructive ships at the time, Hanland offered them a contract instead. After the less than well-received unveiling of their fuel tanker "superweapon", Hanland asked them to create something more "down to Kerbin", so to speak. Allegiance- Hanland Part count- Can't remember (between 200 and 275) Craft file- http://www./view/k4w752wh1ef95ws/GIR-Tec_-_Havok_Cruiser_v3.craft Operation Manual - Missiles are staged, since I'm trying to keep this vessel as simple as kerbanly possible.

A lot of that delta-v is going to be spent thrusting against the atmosphere to get into a suborbital trajectory. Once you finally leave the atmosphere it takes maybe 200-1500 dV to circularize depending on your apoapsis (the lower the more dV you have to spend to reach orbital velocity at your altitude) and then most orbital maneuvers don't take that much dV e.g. going to the Mun is 800 or so (to get there and smash into it, that is - realistically you will want to get captured into a stable orbit and maybe land, oh and maybe return as well). Interplanetary isn't actually that much more expensive, and if you are going to a planet with an atmosphere you can use that to slow you down upon capture instead of thrusting retrograde at the periapsis, it saves a ton of fuel (see aerobraking).

It's really hard to imagine how you'd do that with a chemical rocket. Not only are the pumping systems completely different for different kinds of propellants, but also the combustion chamber and nozzle have to be designed completely differently. For instance, a typical RP1/LOX rocket engine might have a chamber pressure of 75 atmospheres while a typical LH2-burning engine would have a chamber pressure of 200 atmospheres or more.

In the final days of Kerbin's 0.20 Defiance Aerospace program, an ambitious attempt to build a revolutionary space station to provide needs for every interplanetary-bound craft. Something to leave behind for those in 0.21 and beyond. Enter Ascension Station. Weighing in at 200 tons (not including Kethane weight), 634 parts, and room for 27 Kerbals, this station holds large supplies of Kethane, xenon, basic rocket fuel, and monopropellant. It acts as a recharging facility for any craft needing electricity, has a garage for 2 RCS Bikes (not included), an escape pod bank in case disaster strikes, multiple comms. arrays, several hydroponics modules, state-of-the-art scanning and sensor technologies, and a holographic system display. Also it looks really pretty. Sadly it's too laggy to be useful. It's only there for the Rule Of Cool.

Warcraft III (not the original RTS, just maps), racking up 250+ playing hours in a span of 1 and a half year. Minecraft will be the next one, even if I'm not playing it anymore for a year now. Racked up estimated 200+ hours playing it in a span of just 2-3 months followed by a year of intermittent gaming, and there was even a day where I've played minecraft 13 hours straight in one day during my peak of minecraft playing life.

Sí, Camarada Anónimo, a todos les pasa. Eso es porque el motor que KSP usa, Unity, no soporta más de un nucleo. Es un problema común, depende de la cantidad de partes que tenga tu nave. A mí con 150-200 partes ya me empieza a joder. Generalmente se te va a cascar por el micro antes que por los gráficos. Lamentablemente Unity no es propiedad de Squad, así que ahí no hay opción, solamente esperar a que algún día lancen una versión de Unity multi-nucleo y que Squad la integre en KSP.

Just about 200 hours now, so this is drawing close to the time I used to spend on the Sims

I know it's possible to exit a gravity assist with as much as 200% the target object's velocity plus the velocity you started the encounter with, but that's assuming the target object is so much bigger than you that you can pretend it's infinite and immovable. I also know gravity assists are less efficient the further you are from the target object, and that if Earth and Venus get too close they'll start tearing chunks from each other (that's not a bad thing when you're trying to destroy planets, but it is if you want to throw one in a particular direction), so there is going to be an upper limit. Is 60% reasonable? Too high? Too low? Beats me, and I don't like to pull numbers from thin air. I don't deny that a Venus slingshot is a cheaper way to get to Jupiter than going directly, but the energy required, whatever system you use to put that energy into Earth, cannot possibly be less than disassembling Earth where it is. That is one way of accomplishing it, but I don't think it's going to be any more efficient if you put a certain amount of energy to fly an asteroid past Earth and accelerate Earth by a little gravitational coupling, than to just put that same energy into pushing Earth directly. I can't prove it though. I wonder if there are even enough asteroids; the entire belt put together only weighs 4% as much as the Moon. I only said that's how much energy it takes. It will take at least that much energy no matter what the technology is. I didn't say it would take any particular period of time, I just used days of the Sun's output as a way I could compare numbers for amounts of energy I can't possibly grasp otherwise. If you want to spread the matter of the Earth apart far enough that it doesn't pull itself back together again, whether in one blast or a slow push, it takes 2.2405*1032 kg*m2/s. That looks like a big number to me but I have no real idea what it means. The Sun puts out 3.86*1026 kg*m2/s every second, also big and scary and meaningless to me. But divide one into the other and you find the minimum energy for destroying Earth is equivalent to 540,440 seconds, or 6.7 days, of the Sun's total output. Do it in an instant or spread it over eternity, this is the absolute minimum it takes to overcome gravity. Similarly, to move Earth as far as Venus to set up that first slingshot takes a certain minimum amount of energy. Do it however you want: push the Earth, push asteroids that pull the Earth, push Mars and play interplanetary 8-ball, doesn't matter. No matter how you deliver the energy, it's still going to take nearly three times as much energy as blowing Earth apart just to get as far as Venus, with yet more energy needed to finish the job. We can make it LESS efficient if we want to, we can waste as much energy as we want, but we can't make it any more efficient than this perfect-world minimum. As far as method goes, I'm still partial to the massdriver idea. It's on the edge of current technology, I admit, but I'm with you on this point: long but efficient FTW. Centuries? Longer? Wait a second, maybe it WOULD use even less energy, since as you slowly reduce the mass of the remaining Earth, each shot needs less energy to overcome its gravity... nope, that's balanced out by the early shots having the entire planet dragging them back, it'll work out to the same as just scattering the whole planet in a single blast. You win again, physics!! Anyhow, the numbers and equations I used are mostly on this page, plus a couple numbers (mean distance of Venus from Sun, etc) looked up on Wikipedia.

Good idea WooDzor . Here is an updated craft file: http://www./download/rqg90gv1s16qpgx/Kerpollo_17_redux.craft The Rover got a make-over. Now with: Bigger battery, Anti-turtle leg, Wheels positioned for optimal stability, single piece I beam construction, and less parts altogether. I also omitted the dish, and replaced It with regular (less obtrusive) antenna. Part count was reduced to exactly 200 parts.

I've very much enjoyed the game so far, but after having put 200 hours into it, I've almost everything there is to do as it stands. Without any further updates, I would put the game down and probably play it only sparingly from this point on.

Yes! That was totally what I was trying to do.... *CAN YOU FEEL THE SARCASM?* Yeah... I was not intending that to be a part of the initial design, but I am glad it is. I only did 4 test flights with the Jool II-200 before I posted in the forum, and it preformed every time flawlessly. I designed only 1 ship to be able to fire engines with mechjeb and remain on track with an offset center of mass, and that one is making it's debut.... Chapter 5: Home Before Dawn -This is Trawler in the Dark, Jeb, and we have over-watch.- Jeb: Ok, how do you keep getting this line? Kirk, is this a feed coming in to us through the quantum communicator? Kirk: I have no idea what you are talking about Jeb. Just get to the ship. Jeb: Yeah. I'm on the way. Jeb: Do I really need all these tools? Kirk: Yes, yes you do. Jeb: Well, I am close by. Kirk: Cool. Jeb: So, what am I supposed to do again? Bob: Just go to the ascent craft, hop up next to the port.... starboard.... THE RIGHT SIDE RCS containers. Bill, if you try to correct me again, I am going to hurt you. Jeb: Got it... Lets see.... This is the right side. Jeb: Alright. The glare is too high, I am turning off my headlamps. Kirk: Wait, Jeb, what if it escapes. Jeb: I think it's dead. Kirk: How can you be sure? Jeb: I just turned on the engines. The glow from them for that fraction of a second as it burned away that... Monstrosity of a dish was rather cool. Bill: DAMNIT JEB! We needed that for a sample. Jeb: I know, Remember two nights ago when I used the 3-d printer in the new housing module? Bill: Yes, and that is the reason why we had to wait before making the components that probably broke. Jeb: I made a box, and I got a sample. It's bouncing around inside this thing.... Kirk: Well, that's good. Bob: Jeb? Jeb: Yeah? Bob: That's not the right side of the ship. Jeb: Oh. Bob: Yes, that's right. Just plug in the diagnostic comp.... Jeb: Done. All the red lines are good, right? Bob: .... Nooo....... The readings keep jittering. Jeb: Well, that doesn't sound good. -Jeb, just tap the push the cable slightly more in. The signal is corrupted.- Jeb: Stop doing that! Bob: What are you talking about? Jeb: Nevermind, ignore it. Bob: Alright... Looks like we only need to replace one circuit board. Jeb: Cool. Come on over! *Ten minutes later* Bob: Jeb. Jeb.... JEB! Jeb: zzzzzz.... WHAT! WHERE! WHEN! Bill: Who? Bob: Don't encourage him. Kirk: Hey Jeb. Jeb: Ah. You guys are here. Just... Lets get into this thing and get out of here. *A minute later* Jeb: That was fast. Lenwise: Orion Ready for pickup. B9K: We regret to inform you we have insufficient fuel in the ascent stage to get to the proper orbit. Jeb: Aright. Let's use the lander engines. Bob: .... Wait, lets call mission control first- Jeb: Too late. FULL POWAH B9K! B9K: We have enough Delta-V to make the rendezvous. But not with the Orion. Jeb: What do you mean? Kirk: We have an incoming lazor transmission. Jeb: I bet I know who it's from. Kirk: It's from Trawler in the Dark. Jeb: I should have bet money on it. Kirk: No one would have agreed to that bet, as we are the only ones out here. Jeb: Still, I should have tried. B9K: Circuliarization burn ready. Jeb: Fire! B9K: Warning, out of fuel in landing stage. Jeb: Jettisoned, and fireing smaller eng-WHOA! Kirk: AARRRG!!!! Bob: Damn that has some kick. Jeb: Wow. 5 G's. Bill: I have never felt that much weight on my face.... Kirk: I feel so much anger for the creator that gave us heads that were 1/4 the mass of our bodies. Jeb: Yeah.... B9K, make the engine accelerate slower. B9K: Done. We are coming up on the Trawler in the Dark. Jeb: That name is just so... Odd.... Jeb: And now it's dark! I can't even see the dock. B9K: I have entered an automatic control zone- dark-side protocols are ordering me to control docking. Jeb: That can't be good. B9K: I don't like it either. Jeb: I still can't see anything! AND the Microprobe got retrieved! Lenwise: We made the burn already. Doing a correction burn now. Lenwise: Incoming. B9K: Initating dark-side Protocol. *Thunk* Lenwise: We docked. *Sound of doors airlock* Mekan1k: Hey guys. Jeb: Mek! Yo, dude! So this is the secret project you were grinning about. Mek: Yup. Kirk: What is this? Mek: Officially? This is the first deep-space Warship. Jeb: Seriously? Mek: Oh, yeah dude. Jeb: But how is it Deep-space? Mek: It has a massive centrifuge, a greenhouse, and an inflatable living area. Kirk: Wow. I love the fact there is maybe enough green material here to... What? Make a salad? Mek: Geneticly Modded greens. Adapted to living in zero-G from superfast growing tangler vines, and completely edible. Sewage is sterilized in the reactor that we just walked through, and water is extracted from the super-heated remains in the reactor and centrifuge. A slurry is pumped then into those sponges, which the roots grow into. Shepney: How do they taste? Mek: Like lettuce. Shepney: Crunchy, sweetish/bitter? Mek: Like water, with crunchy. Jeb: So.... What delta-V does this thing have? Mek: Around 24000 dv. Max acceleration is... Classified. I have no idea. Jeb: Why not? Mek: Anti-Jeb countermeasures. It has a speed governor. Jeb: I hate the engineers. Mek: I am an engineer, Jeb. Kirk: .... Alright.... Anyway, can we get access to the micro-probes? I would like some shots of the ship. Mek: Sure. You won't be able to release them, but alright. Kirk: Nice! Mek: I know. She's my Lady. Al1c3: Sir, the launch window is approaching, and we have finished refueling the ships. They need to decouple. Mek: Right, well, you guys need to leave, and I have a secret mission to go on. Jeb: What secret mission? And who is that? Mek: Test a fuel retrieval scoop, and that is my Custom AI for this ship, Al1c3. Al1c3: My name is an anagram. Active Logistics Construct 13. Jeb:.... That seems dull. Al1c3: .....? Jeb: Not you, you are interesting. I meant the mission- it must leave alot of spare time. Mek: I am working on my business minor. It's not dull. Jeb: I will take your word for it. Bill: Alright Jeb.... This reactor is giving me the creeps. Shepney: MMMMRPH! Jeb: Yeah, right... I need to get this sample back to the KSP. Mek: It looks rather pissed. Bob: MMMPH, mrphm. Mek: Please don't eat my o2 scrubbers. *A couple minutes later* Mek: Guys, I see a problem with your plan. Jeb: What is wrong? Mek: The other module cannot fly itself. B9K: That is correct. Shepney: Mmph! Mmmmmmpphhh!! Mek: Yeah.... The vines have a REALLY spicy aftertaste. Did I forget to mention. Bob: YES! OH DEAR KOD WHY!?!!??!?! Mek: Serves you right. *Thunk* Jeb: Aaaannndd.... We're Docked! Mek: Good luck guys. Activating fusion engine feild. Jeb: Why are you saying that? Mek: A warning- you may feel a slight push. *THWOMP* Jeb: what? Mek: I love this ship. Kirk: Jeb? Jeb: ..... Bob: Jeb? Jeb:.... Bill: Just do this to get his attention. Jeb, I will give you a wet willy if you don't snap out of it. Jeb:.... Bill: Fine. *squeege* Jeb: OHWHYOHWHYWHYWHYWHYWHY!!!!!!!! Bill: He hates that. Jeb: Yes, I do hate that. I also want that ship! Bill: Maybe you can get command to make you one. Jeb: Maybe. Bill: Anyway, look at this. Jeb: Damn. On an escape trajectory into orbit around kerbin. Mek is a bit annoying with his cheerfulness, but he is good with these ships. Mek: I can still hear you Jeb- you left the mike on. Jeb: Oh.... Bill: Any idea why that ship has no solar panels? Mek: Solar panels are visible from a long way off, and reflect alot. This ship is designed for stealth. Jeb: Most of it is orange or white! Mek: The reflective paint changes the refraction of reflected light into different wavelengths. Keeps us stealthy- we cannot be seen on active scanning. Jeb:.... Kirk: Oh not again! Jeb:.... Mek: Jeb? Are you ok? Jeb: I want that ship. Al1c3: I am not an object! Mek: Actually, Al1c3, you are. Al1c3: I still resent being drooled over like that. B9K: Shouldn't I be resentful? He is drooling IN me. Al1c3: I agree- you should be resentful. Bill: This is not healthy.... This is emotional feedback. Mek: Yeah.... I think I will say goodbye. Jeb: Bye dude. *Click* Jeb: He is annoying! Mek: You just set it to record. I will just terminate the call at this end. *Beep* Jeb: Kirk: Bwahahaha! Bill: Jeb, just- Jeb: Don't start. *A few hours later* Jeb: Correction burn. Aerobrake in a few hours. Jeb: Burn finished. Bill: Jeb- Jeb: NO. *A few hours later* Bill: It looks nice out there- Jeb: No. Aerobrake will repeat in 4 hours. *4 hours Pass* Jeb: No. Bill: I Didn't say anything! Jeb: Still counts. Aerobreaking. Kirk: I can see the KSP from here! Bill: Hey, yeah- Jeb: No. Bill: ? Jeb: Aerobreak again in 2 hours. *2 hours pass* Jeb: Aerobreaking. Jeb: Nice desert. Kirk: Yeah. Bob: I can almost see the pyramids. Bill: Really? Jeb: NO. Bill: Jeb, stop that. Jeb: NO. Bill: ? Jeb: Circularization burn in 10 seconds. ... Jeb: Burn complete. Kirk: Nice mun! Bill: Cool- Jeb: NO. Kirk: So... Rendevous with the habstation? Jeb: Sure. Bill: Alright. Co-ordinates in. Jeb: Right. Bill: Are you done with the 'no'ing? Jeb: Maybe. Bill: Alright. Jeb: Burn activated. Jeb: We are on-course for hab-base. *Ten minutes after docking* B9K: Atmosphere restored. Welcome to the Habstation. Inflating Ring. MC: Hey guys- welcome back. We have some more flights scheduled, so we need eyes in the sky from now on for a while. Jeb: Sounds like fun! Lenwise: Anyone up for dodgeball/soccer in zero-g? Jeb: Lets keep the ring from spinning, and play in there! MC: Alright. Flight in a few days. You guys will be monitoring the launch and assembly of several components. Jeb: Cool. Hey guys- remember, the enemy's goal is down! Hey guys. Hope you enjoy the new chapter. Next one will be either Friday or Saturday.... I still am fighting off this cold. So, well, have fun, and don't forget your atmosphere!

I usually use the autopilot. When I docked last night, I used the rendezvous auotpilot to get within 200 meters and did the whole thing manually. No smart A.S.S. at all

I added the miniature rocket fuel tank right before the front fuel tank, which was mostly for the warhead simulation. All of my craft also use FAR, so that is necessary. The Foxhound handles just like the real one with FAR: not quite a fighter, but it's definitely no slouch in agility if you play around with the craft for awhile and learn how it handles, although the MiG-31 is mostly meant for low altitude interception and reconnaissance roles. The cruise missile has a theoretical range of over 2000 km's (and with the drop tank edition I'm currently testing, over 6,000 km's at minimum), and both editions with either the turbofan or the turbojet engine can super cruise at under 200 m's of altitude. The cruise missile, like in real life, is not all that maneuverable, so you have to align the cruise missile for the terminal phase of the flight. If you want to make a direct hit, turn the engine on it to a very low thrust rating, which should make you subsonic and allow for greater accuracy. If you want a good and stable plane with FAR that can turn on the dime, then you should check out the F-15A and C I'll be posting soon. What's funny though is that the MiG-31 has over 2000 units of fuel, which makes a great combination with the turbofan engines since they only sip the fuel. I actually haven't tried circumnavigating Kerbin with this craft yet, but I'm sure it is almost, or just capable of doing so. PS: Watch out for where the fuel is being drawn from, because that could easily unbalance any craft, especially with FAR. Enjoy the Craft files Guys.

Sure. Pics of Jool II-200 without payload

On a different note, could we get a screenshot of the Jool II-200 with the VAB in the background? I would like a size comparison.

The 3.75 meter space craft on the bottom is attached by 2 Clamp-o-Tron docking ports. Also, the design specifications call for EVERY single module being capable of detaching itself from the ship and reattaching elsewhere. Also, the vessel weighs 252.15 tons in current design, beyond the carrying capacity of the Jool II-200 heavy launcher. As such, at least 2 trips would be necessary, perhaps more, to lift the vehicle. It would also require extensive amounts of electricity to maintain structural rigidity with quantum struts. Conventional struts would compromise the design specifications, by rendering the modules unable to undock.

The Jool II-200 seems perfectly designed to do a 1-shot lift to orbit for the fully assembled station, without (relatively) weak docking connectors in the way.

Depends very much on how large the colony is. And whether you're dropping habitats or building underground. A bit of lateral thinking can drop the launch masses a lot. Dropping habs is in itself very inefficient. As a example you'd need a 100m x 100m area to grow 9 tonnes of wheat per 6 months (based on current worldbank stats of wheat yields per hectare). If you did that as a hab 3m high with the same wall construction as the iss (about 5mm aluminum on average) you'd have to haul 171 tonnes of metal per hectare just to build the shell structures. More mass required for fitting out etc. So say around 200 tonnes per hectare. So for 10 hectares you'd need about 2000 tonnes of materials and fittings. At 90 tonnes total yield per 6 months you'd break even in 11 years or so (and have a crew thoroughly fed up of eating toast by the pound for every meal) Of course you could reenginneer the entire system so that rather than dropping habs you're digging underground to make space to grow food. One person with a single 30 tonne JCB excavator can dig a 100m x 100m x 3m hole in just over a month. Five of them and you'd be down to a week. Dig out ten spaces, seal the inner walls, roof and ceiling with high strength airtight resin and fit the same 30 tonnes of supporting equipment per space. Total launch mass would be ((5*30)+30)+(9x30) 450 tonnes with breakeven @ 2.5 years. Plus you still have 150 tonnes of excavating gear you can use however you want, even if only to take your mind off the darn toast. I'm rather fond of the second option

It would have to be between 200 or 400km of the cost of the launch site, either in the Atlantic (for a KSC launch) or in the gulf of Mexico (of they launch from the new Texas site) which is not very practical. You would need to refurbish something like an oil rig. The infrastructure cost would negate the small savings you get from reusing the first stage.

This link says one person needs about 400 kg bare minimum of food for 2 years. So 200 kg per person per year. If you include more variety and taste in your food, and include packaging, it might go up to 500 kg per person per year. That's about 9 tons per year for 18 people. This is assuming all the water is recycled. It would be less for kerbals.

三足烠(Sanzuwu) Based on a hypersonic test vehicle I built for the old maching bird thread, I figured it could be easily converted into a thoroughbred SSTO. Well, I can now tell you that it wasn't easy. I'm not sure if it was because of the low wing profile or having the CoM and CoL too far back, but it took a long time to make this thing stable. The good news is that it's now very flyable. With a TWR that would make a grown man giddy, the Sanzuwu gets to altitude faster than Jeb can say "Sloof ouy tiurfeparg erom tae!", and laughs in the face of atmospheric drag. Once in orbit, it switches to its ion engine to make hyper-efficient manoeuvres. It has decent cross range capability as well; a good ascent to an 80km circular orbit will leave you with about 200 litres of liquid fuel and 120 of oxidiser, meaning at least 100 units of fuel left for atmospheric flight after reentry.

Im newly registered, but ive been reading these forums for some time now, ive done a lot of things in KSP (almost ran out of ideas:)), and im also hooked up on caffeine, nicotine, and broken dreams of getting enough sleep. This thread could be classed as "new to", "welcome" and "how to" at the same time. Since its my firtst post, i hope i wont get burned, but if i will i wont be sad since stuff like this happens. Admins feel free to put it where you feel it belongs. Im just asking for an opinion and some suggestions on my replica of ISS. It took some time for the mods to work together and not cancel each other out, the ISS mod, the Soviet pack and the ESA pack (just for the ATV and ariane). The station is not completed yet, but it takes time and effort to keep the part count down, its 114 now, and my PC cant really handle much more than 150, its an old pentium D running 3.4GHz with 4 gigs of RAM and 512Mb Radeon, no SSD and other fancy stuff, so 200 parts makes some big lag. I will be online at the somewhat same time everyday (greenwich +1), im building a sailboat you see, and it takes a lot of my daytime, since im dependant on daily temperatures and humidity, so ill update mostly at night. But enough of that, here are some photos: The solar and cooling panels are closed, because hey cause much lag when everything is deployed and makes docking a living hell. Also, sorry for my not perfect english, i come from Slovenia. And as Scott Manley taught me, Fly Safe!

How would you make a reusable shuttle from LEO to LLO? Where does the fuel come from? You need 4 km/s of delta-v to go from LEO to LLO; assuming an Isp of 400, that's at most 1/3 of your shuttle's mass being usable payload, probably less accounting for structure, engines and empty tanks. And that's one way. If you also wanted to go back the other way without refueling, you would need a shuttle at least 10 times bigger than your payload. If it carries people, it needs life-support and other systems. The Orion crew capsule is 9 tons, its service module is 12 tons and it's capable of 1.6 km/s delta-v. It has enough room for 6 people to LEO, but probably fewer than that to LLO. So if you scale it up to a shuttle capable of carrying 6 people from LEO to LLO and back, it would have to be around 200 tons! And that's not including a lander. So I'm not really sure what you mean by a reusable "Moon shuttle". For cargo, you could use high-efficiency low-thrust propulsion, but the transit times are too long to take up crew the same way. A Mars transfer vehicle would probably be something like an ISS module, a little bigger to support 6 crew. The food needed is not that much, something like half a ton per person per year. So maybe 5 tons for the journey to Mars and back, with the habitat weighing another 30 tons or so. A way to make it partially reusable would be to use an Aldrin cycler along with crew-carrying spacecraft to go to and from it. The habitat would therefore not need any fuel except for course corrections. If you use an Orion-like spacecraft like with the lunar shuttle (carrying the crew and the provisions), you would need around a 60 ton rocket in LEO to get the ~4 km/s required to rendezvous with the habitat. Landing on Mars takes around 1 km/s delta-v. Taking off from Mars and rendezvousing with the habitat again takes around 6.5 km/s. So that part would probably not be reusable. Anyway, there's a lot of possible architectures for both a Moon shuttle and a Mars shuttle. If you only do a single long-duration mission to the Moon or to Mars, the mass in LEO requirements would not be too far off between the two.

Already 3 pages of responses, but I've got a station around Kerbin, not even finished due to part lag, but it was done in separate launch windows as the station orbits and passes over KSP (assuming you left it on a roughly equatorial orbit. Technically if you're doing it piece by piece I think you have to do it in more than one window, as the station orbits, at least if it's in Kerbin orbit I guess. If you're talking about other planets then yeah, that's a different story. You could get multiple launches in one window. I started a small fuel station in Munar orbit made up of ascent stages that still had fuel in them when I took my kethane miners to the Mun. Built them with Sr docking ports where the engine attached so I could smash the engine into the Munar surface then used that to dock the two ends. They were launched in separate windows, not that far apart, maybe a few kerbin days between launches, partly because I was testing the first miner out to make sure it'd work. I think if I were planning on a station in orbit around say Duna, I might do multiple launches, sort of put it together in kerbin orbit, maybe either as a long "space train" or maybe using some sort of + arm shaped thing to attach sections for transport, then likely use some sort of RCS or LV-N tug to position everything where it goes. Haven't gotten to the point of doing that though as I just recently decided to start Kethane mining, plus as I mentioned before my laptop doesn't handle much over 200 parts very well. lol
