  1. Since the first planes evolved, kerbals always wanted to ride them without flying them. Then, they were able too with the airliner. But ever since the founding of the Kerbal Space Center, kerbals have wanted to go to space without all the training. Well, let’s see if they can! CHALLENGE- Build 1 (or many) passenger SSTO’s that fit with the rules, categories, and qualifications. RULES- The craft must be an SSTO that takes off from the runway and lands on a runway (doesn’t need to be KSC, modded runways allowed). The craft must have pilot(s) and flight attendants unless stated. The craft must be able to land on and return from the destination. No mods or DLC’s involved in the craft. MechJeb autopilot not allowed, though orbital information and planners are allowed. Visual and informational mods allowed. No cheating with hyperedit, debug menu, etc. Craft must be of your own design. Please post the craft launch cost (cost displayed in SPH minus amount gained in recovery). When posting, please put your: company name, type of category, launch cost, passenger/crew/pilot count, and Delta V amount. Also include at least 3 pictures proving the functionality of the craft. CATEGORIES- Private SpaceLiner: 2-6 passenger capacity, 1 crew, 1-2 pilots. Destinations- Mun, Minmus, Gilly, Ike. Small SpaceLiner- 12-36 passenger capacity, 2 crew, 2-3 pilots. Destinations- Mun, Minmus, Gilly, Ike, Duna, Dres. Medium SpaceLiner- 37-55 passenger capacity, 3-4 crew, 2-3 pilots. Destinations- Mun, Minmus, Gilly, Ike, Duna, Dres, Eeloo. Large SpaceLiner- 56-125 passenger capacity, 5-7 crew, 3-4 pilots. Destinations- Mun, Minmus, Gilly, Ike, Duna, Dres, Eeloo, Pol, Bop, Val. Huge SpaceLiner- 125-250 passengers, 6-10 crew, 4 pilots. Destinations- Mun, Minmus, Gilly, Ike, Duna, Dres, Eeloo, Pol, Bop, Val, Laythe, Tylo, Moho. Super SpaceLiner- 250+ passenger capacity, 12-30 crew, 4-7 pilots. Destinations- Mun, Minmus, Gilly, Ike, Duna, Dres, Eeloo, Pol, Bop, Val, Laythe, Tylo, Moho, and Eve (if you dare). ADDED NOTES: The stated destinations does not mean you can only visit those places. As an example, you can take a private SpaceLiner to Ike, refuel, go to Duna, back to Ike, refuel, and go home as if they are connection flights. When I see a craft that catches my eye, I will ask for further details and/or craft file. If it is up the the highest standards, then it will go onto the Best SpaceLiners Leaderboard. Have fun designing and flying! Best SpaceLiners Leaderboard
  2. Welcome to Spaceplane Innovations, the online leader in executive Spaceplane sales. Dropping tanks is so yesterday, earn back some self-respect by going fully-reusable today! We have Interplanetary leviathans and nimble Mun Hoppers, Single-stage-to-anywheres and Cargo-carrying brutes. All capable of high crew capacity and total galactic dominance. Shop now, the SSTO of your dreams is just a click away. We also make rockets. View the full catalogue! Click to view the full catalogue! Artemis Class These spaceplanes are the biggest of the bunch (so far), consisting of 3 Mk3 fuselages side-by-side, with the ability to carry an enormous amount of cargo/crew to many different interplanetary destinations. The Archangel is the first of the Artemis line, and has the ability to easily go to Duna or Mun with 60 Kerbals, and pilots who have a good grasp of gravity assists will find further destinations, such as Eeloo, very possible as well! Video - Mun mission Video - Eeloo mission The Artemis is a monstrous spaceplane capable of carrying 124 kerbals to LKO with just over 4,000 m/s of DeltaV to spare. It can't fly quite as far as the Archangel, but it is quite capable of going to Laythe and back without refuelling. Video - Laythe mission Archangel Download Archangel Download Archangel v2 Download Artemis Download Argus Class These spaceplanes are big, brutal, and capable of interplanetary missions without breaking a sweat, independent of mining or refuelling. WARNING: You will need to replace the landing gear on the Argus II and Engadine with larger ones if you're playing in 1.1 or later. The Odyssey will work fine though. The Argus was built as a Bop SSTO, but in the end was mainly used for Duna cargo missions and Eeloo voyages. It doesn't work so great in 1.05, and so is no longer sold by Spaceplane Innovations. Video - Eeloo mission Video - Duna mission The Engadine was the hugely popular successor to the Argus, packing more DeltaV and a massive 20 Kerbal capacity. So far it has only been used for Mun landings, but we at Spaceplane Innovations believe it could easily be used for Duna returns too. Video The Argus II was built following the success of the Engadine as an ultra-long-range SSTO. It has more m/s of DeltaV in LKO than any other SSTO produced by Spaceplane Innovations. Video The Odyssey was built to replace the legendary Engadine. doubling its crew capacity while retaining its high range. Duna and Gilly missions are well within its capabilities, as well as Eeloo and Jool for those who have mastered the fine art of gravity assists. Video - Mun mission Make no mistake: these planes are unruly, bulky, unbalanced and difficult to tame. They are therefore best suited to more adept pilots who understand gravity assists and how to efficiently ascend from Kerbin. They're hard to master, but for those with the patience to learn their functions the pay-off is huge. Argus II Download Engadine Download Odyssey Download Acacius Class Acacius ships have an IRSU on board and are capable of refuelling themselves using mining equipment. These are at the forefront of exploration, and are the best "single-stage-to-anywhere" planes we offer! Only one model is currently available for consumers: The Acacius 2 is the first SSTO produced by Spaceplane Innovations to feature the "Single Stage to Everywhere" guarantee. Doesn't do Tylo. Or Eve. Or Jool. These craft are ideal for beginners who want to get to grips with gravity assists or the Jool system, without having to worry about fuel. WARNING: You may need to replace the landing gear with larger ones if you're playing in 1.1 or later. Video Acacius 2 Download Dune Class Before the Argus class, there was the Dune class. The second oldest class of spaceplane made by Spaceplane innovations (after the discontinued Revenge class), these are lightweight, agile, and pack enough DeltaV for Duna, Minmus, Mun and Gilly. Flybys of planets further out are also possible. Dune 3 is the latest and greatest in this class, sporting 3 seats and a cosy interior. These are moderately difficult to use, but experienced pilots shouldn't have too much trouble. WARNING: You may need to replace the landing gear with larger ones if you're playing in 1.1 or later. Video Dune 3 Download Phantom Class These SSTOs are the little-brothers of the Argus Class, and are slightly larger than the Dune class. WARNING: You may need to replace the landing gear with larger ones if you're playing in 1.1 or later. With room for 6 kerbals, the Phantom class is currently offers 3 models: The Minmus Trainer is the easiest-to-use SSTO sold by Spaceplane Innovations, and was specifically designed to train budding kerbalnauts in the fine art of Minmus SSTO-ing. Only the instructions are available for purchase, so that pilots can also learn how to build an SSTO too! Video (SSTO Tutorial) The Mun Phantom was the first Phantom Class SSTO packing enough DeltaV for Mun and Gilly landings, in addition to being able to do Duna flybys. Video The Mun Phantom 2 is a modified version of the Duna Phantom, packing a spacious cargo bay for all your rover carrying needs! Video The Duna Phantom is able to carry 6 kerbals to Duna and back, all in a sleek Mk2 fuselage!

  3. Hi All! I've been trying a little more with SSTO spaceplanes recently. I've done some in the past, mostly small ones with stock parts, but in this heavily modded career game I wanted to try big, so I built this one using moslty OPT parts, which I wanted to use for a space camp mission (bring 15 tourists to orbit). It actually has a pretty decent TWR, not a lot of DeltaV probably, but I haven't tuned it yet...mostly because I can't get it past 370 m/s or so. In the picture attached you can even see that I'm pitching down, but even pitching down, my speed was DECREASING... So. I'm showing the aero overlay, by doing some googling, I saw people seem to suggest drag from clipping parts might be a thing. I can't honestly think of anything else, given the large wingspan and high TWR. Is drag what I'm looking at? If so, how do I fix it? Thanks in advance!
  4. I present to you fine spaceplane enthusiasts... the Kerbal Wind Tunnel mod! We all build spaceplanes to fly faster and higher, but how do you know how fast or how high your current design can go? In the real world of aircraft design, engineers calculate the flight envelope for their aircraft before the first test flight rolls out. This mod runs your spaceplane through a virtual wind tunnel while still in the SPH and predicts its engine and flight performance at every speed and altitude. It also gives you a readout of various performance curves, plotting against angle of attack: ... and velocity: Try it out and start building even better spaceplanes today! You can even output the data to a CSV file to incorporate knowledge of the performance data into a KOS script or the like! Check out this Imgur album for more details on these images and more: https://imgur.com/a/D2i4Fge Download it from GitHub: https://github.com/DBooots/KerbalWindTunnel/releases Or SpaceDock: https://spacedock.info/mod/1927/Kerbal Wind Tunnel Source: https://github.com/DBooots/KerbalWindTunnel Released under the MIT License (with sub-components under their own license). P.S. This mod incorporates a pretty sweet graph-drawing library I made. If anyone's interested in super-simple graphing of data, hit me up.

  9. After much trial and error, I've finally managed to make my second ever functional SSTO, and the first SSTO I've ever created with a useful payload other then it's pilot! It's built to enter orbit, land on Minmus, spend about 2 and half months processing ore, then lift off to interplanetary space with 6,000 delta V to spare! Kerbal X Download Page Notes/Trivia: The crafts' front-most two fuel tanks are intentionally under-fueled! This was done to help achieve liftoff on the run way; when full, the craft was too unstable for me to fly properly X3 You might want to take this into account if you decide to refuel and take off on Kerbin. Alternatively, you can try to fly it fully fueled if you think your up to the task; I doubt I'm the best at flying :Y There's only one pilot seat and no probe control (making flying with an engineer not very ideal), and the ISRU module and drills are the smaller variants. Refueling takes awhile, even with stock speed up set to max! It does hit 4,000 delta V around halfway through refueling, so you can lift off partially empty if you know where you want to go, or need more TWR. Lift off from Minmus can be kind of tricky, as the craft doesn't have the reaction wheel strength to pitch up at full fuel, and the craft likes to curve after a while and slam one of it's wings into the ice! Simply retracting and rextending the landing gear quickly can help you ascend if you don't have a convenient ramp to use. Feel free to add your thoughts and/or suggest improvements, this is my first serious SSTO, and I'd love to keep building upon what I've learned while constructing it!

  11. This is my first craft thread, so advice would be welcome if I am in conflict with any conventions. LKO stats have been adjusted for 1.8 aero changes (improved performance for this craft). Big Plane to Anywhere (figuratively) https://steamcommunity.com/sharedfiles/filedetails/?id=1875714661 (Nice try, Bill, but I don't think this is what they meant by "long range ISRU craft"...) Well, it's been a long time coming. I'm mainly a rocket guy, but when I do find myself in the Spaceplane Hangar I very easily get obsessed with fiddling with my designs, more so than with the rockets. Anyway, I think I've finally gotten this to the point where I no longer have to be ashamed to put it in view of the public. Let me know if I'm wrong! If I'm being honest, the series of planes that this is a culmination of probably began life as the concept, "like my first spaceplane, only bigger". But eventually an actual mission materialized: to carry a scientific exploration team to Laythe and (almost) anywhere else with a complete science package and ISRU that wouldn't take months to refuel with. One development I'm a bit proud of was the realization that I could attach radiator panels to the reaction wheel that was adjacent to both of the drills and the refiner, elegantly taking care of all my core heat xfer needs. This development allowed me to finally have a truly streamlined airplane, since I had formerly had medium TCSes attached to the exterior. Two panels and two small TCSes have less than the mass of one of the two medium TCSes, let alone the aerodynamic improvement! The small TCSes (middle of picture) are for actual part cooling, and aren't necessary, but having at least a little active cooling capability is handy from time to time, e.g. cooling off during a multi-orbit aerocapture. (The panels are terrible at non-ISRU cooling in general, and the ones on this vessel in particular are nearly useless at it.) The construction of this spaceplane does not use offsets at all, nor any part clipping aside from the wings tilting into the nacelles. This was a design choice. Table of Contents: Statistics: immediately below the table of contents Atmospheric flight characteristcs: Balance; Lift; Takeoff; Ascent; Reentry; Landing: approach, normal, water, parachute Vacuum flight characteristics: Takeoff; Landing Miscellaneous: Docking; Adjusting balance; Water landing; Water movement; Design choices Edit history Postscript (action groups) Statistics: —Parts: 100 —Mass: 111.35 tons (57.15 dry) —Cost: 401.29 kilocredits —Vacuum Delta-V: 4.6k to 4.7k depending on if you have oxidizer or nothing but liquid fuel. (counting ore tank, since you can refine it into fuel) —Engines: 4xRAPIER, 4xNERV (0.25 TWR on NERVs if the LF/Ox tanks are empty) —Landing gear: 2xLY-60 in rear; LY-60 and LY-35 in front. (35 for better taxiing and runway takeoff; 60 for rougher terrain and lower takeoff speed) —Mining: 2x large drills, large converter, 2x smallest ore tank, M4435 Narrow Band scanner, Surface scanner (Surface scanner can refine M4435's results) —Science: all experiments; 4 places to put science in addition to the lab (Cockpit, probe core, 2x storage unit) —Communications/Control: Communotron 88-88 (normal direct antenna); RA-2 + RC-001S (with one pilot, can control a probe that lacks direct CommNet connection) —Docking: 1.25m only; no RCS. See Miscellaneous for tips. —Airbrakes?: Yes, 4. Retract before landing. —Parachutes?: Yes, 6 plus 2 drogues; positioned to be moderately rear-heavy, but this is adjustable via fuel movement. Enables safe landing in any terrain or water. —RTGs?: Yes, 8; can permanently run lab and SAS at full strength —Fuel cells?: Yes, 3; can permanently run drills and refiner at full capacity —RCS?: Sort of; 6x Vernors under the nose to assist takeoff/landing in airless environments —How much delta-V is left after making LKO?: Even a pilot worse than me should reliably get to LKO with 24-2500m/s remaining before the +203 from refining the ore tanks. My best so far is 2667 (2870) and I seriously doubt this cannot be bested by an actually talented pilot. Test flight landed on Minmus with 1213 dV remaining. Also goes direct to Mun. —Amphibious?: Yes: can land in water on parachutes or aeronautically, and can take off from water (but only below 25% fuel). See Miscellaneous for details. Atmospheric flight characteristics: —Balance: The center of mass is almost exactly on top of the center of lift both full and empty, in the back half of the rear cargo bay. (About 16.3m from the front of the 26.8m craft, or about 61% of the way to the back.) If you want the CoM to move forward after takeoff, you can lock the tank behind the cockpit (this LF should not be needed to make orbit). This also can help counteract the already mild tendency to nose up at high speed (see below). See Miscellaneous for a tip about rebalancing the craft. —Lift: Tendency to nose up or down while SAS is off is not violent at any speed; very slight down at low speed (<200), a bit up at high speed (300-1000), and very slight up up during final speedrun. —Takeoff: Fully loaded, it can be lifted off the runway at 83m/s (lower on rough terrain due to upslopes) on main wheel (100 for smaller wheel). Consider using the small wheel on runways or flats to gain more speed before liftoff (due to lower angle of attack while on the ground). Left to its own devices it lifts off at the end of the runway at about 99m/s (112 for smaller wheel). —Ascent: After the 1.8 update, it no longer has to stop ascending to break the transonic speed hump. My flight plan, which may or may not be optimal, is: Set at 5° above horizon; it will gradually dip a bit to 2-3° but recover by itself. After going supersonic it will tend to slowly climb in attitude; stay at 5-7° until about 15km altitude, then begin dropping to 2-3° in order to extend final speed run in the 18-22km altitude range. (If you're feeling lazy, you can just let SAS do its thing all the way to 1000 m/s or so.) Activate NERVs when RAPIER thrust falls below 200kN. By the time thrust falls below 60kN you should be around 1500m/s +/-50; switch to rocket mode when jet+NERV acceleration is unacceptably low and aim for the top of the prograde circle (or a little higher or lower, to taste). When oxidizer runs out, drop to prograde lock; the NERVs should be able to maintain or increase your time to apoapsis. —Reentry: It's recommended that fuel be moved foward to the tank behind the cockpit for reentry for extra stability. For example, in testing, given a 100kmX15km LKO reentry orbit and only 500 units of fuel remaining, a neutrally balanced craft struggled to maintain a 40-45° pitch without using airbrakes, while a craft that moved that same small amount of fuel forward had no trouble. It should be noted that the balanced craft had no trouble with a 30-35° reentry profile. 1000 units of fuel (~10%) balanced forward is enough for a radial out pitch to stabilize forward instead of flipping out. Use caution if returning from other celestial bodies; it's not recommended to dig deep into the atmosphere on the first pass without decelerating first. —Landing approach: If airbrakes were used, retract prior to landing as the bottom ones may be destroyed otherwise. Perfect balance and generous control surfaces make it relatively maneuverable for a Mk3 spaceplane. Since it takes off near empty at 53-60 m/s (on big/small front wheels) the stall speed on low fuel should be similarly low unless I'm mistaken. —Landing normally: Try not to touch down at more than 5m/s vertical speed. The fairly wide rear footprint means it should be pretty stable and modest testing has borne this out. —Landing in water: This plane is capable of a safe aeronautic landing in water, which was successfully tested at 25% fuel, but parachutes are recommended for landing in water or very rough terrain. —Landing on parachutes: Even heavily loaded with fuel, this vessel can land safely on its complement of parachutes, but use of engines to help soften the landing is encouraged. The Abort action group opens doors for the parachutes and triggers them. Vacuum flight characteristics: —Takeoff: Fully loaded and on a flat surface, the Vernors are not quite strong enough to lift the nose for vertical takeoff in Munlike gravity. Instead, get forward motion and it should be able to lift off shortly with the help of the thrust attitude, especially if the vehicle runs off the top of a hill. Use of RAPIERs is recommended unless terrain is very flat. —Landing in vacuum: dV can best be conserved by a "reverse takeoff" posture, where final approach retains some horizontal motion while vertical motion is very low, but this is not easy. It is probably more practical to descend on the engines rocket-style, and then transition to horizontal when near/on the ground (fall on the wheels). This has been tested on the Mun. Be careful to keep the plane level (don't let it roll on its side or you may lose a wing). The Vernors can slow the fall of the front end, but this should not be necessary in Munlike gravity. Miscellaneous: —Recommended docking procedure with this vessel is as follows: 1. Rendezvous; 2. Make a close approach (50 meters dock-to-dock* or less), then cancel relative motion; 3. Align to the desired docking port, and accelerate a little for final approach. This technique has been highly successful on larger versions of this vessel docking with still larger vessels. *(Bear in mind that when approaching tail-first the engines are almost 27m closer to the target than the docking port, and flipping tail-to-nose will bring the docking port of this craft when normally balanced 32 or 33 meters closer to the target due to where the vessel's pivot point is. A dock-to-dock separation of 50m would mean a real distance facing away of 23m and 17m after flipping). —When altering the balance of the craft (e.g. to put the CoM more ahead of the CoL), keep in mind that adding fuel to the rear and front LF tanks in a 2:1 ratio will be approximately neutrally balanced, i.e. will keep or return the ship to close to its starting balance. —Water landing (via parachute) was tested on Kerbin at 75% fuel. If your splashdown attitude is close to vertical, your docking port may be at risk of destruction as you rotate down, but this can be prevented by using the Vernors to slow your fall. (Presumably similar precautions should be taken if landing on Tylo.) —The top speed in water is 38.7 m/s when full. The top speed on low fuel is uncertain because during testing the plane unintentionally took off. In subsequent testing, the vessel was able to intentionally lift off when top speed in water was about 70 m/s, when fuel fell to between 20 and 25%. (Highest speeds were obtained when fuel was moved forward and SAS set to prograde.) —Why the precoolers? Although the shock cones more than meet the needs of normal flight, I like the idea of having strong static airflow for those, ahem, "off prograde" situations. They are also handsome. —Why the everything? This design was not arrived at minimalistically; I'm sure there is a lot you could cut, starting with the rear parachutes and airbrakes. But I wanted a feature-rich craft, and those are features, and it is Minmus capable, so there. Having said that, I do still welcome criticism if you think anything is too blatantly unnecessary. —Why no offset? I just didn't want to use offset; a little bit to neaten up the often messy intersections of aerodynamic parts is okay but I often see it used in a way I think of as exploitative. So in a way the only minimalistic thing about this design is the offset and part clipping, which was a design choice. —After the 1.8 atmospheric changes, this plane can actually fly on a 3R+3N configuration, but taking away two nacelles worth of LF completely negates the benefit. It's slightly less dV, significantly less TWR, and a more annoying ascent path; why bother? Well, I could probably just yank one jet off the regular design (keeping 4 NERVs) and limp to orbit, but the dV gain (112 I think) is, while noticeable, quite modest and I would be nervous about sending it to Laythe untested with that much less atmospheric performance. So, how do you like the plane? How do you like the post? Comments and questions welcome. Edit history: 1.1—9/28/19: Added vacuum landing notes. Added "Miscellaneous" section. Made major changes to vehicle (reduced RAPIERs from 6 to 4, replacing two Mk3 side pods with four Mk1 side pods). Edited text accordingly. 9/29/19: Added Minmus picture. Edits to vacuum landing notes and other things. 9/30/19: Swapped location of RAPIERs and NERVs (reducing tailstrike risk); minor text edits. 1.2—10/4/19: Minor adjustment to front wing AOI and location; small but critical adjustment to rear wheels to eliminate drift on takeoff. Added location of CoM to "Balance". Added "Takeoff"; edits to "Ascent" and "Landing Characteristics".) Finally changed top picture to reflect new version of craft. 1.3—10/5/19: Added "Communications"; added more detail to CoM location, "Lift", and "Takeoff"; added RA-2 to vehicle and replaced bottom pair of shock cones with NCS tanks. (Reduced cost by 3300, increased wet mass by 0.91, dry mass by 0.11, part count by 3) 1.4—10/10/19: Updated "Landing in vacuum" to reflect finally testing Mun capability; added "Takeoff in vacuum". Removed 1 fuel cell (3 remain) in the belief that this was enough for even maximum ore concentrations, subject to review; please let me know if this is found to be wrong. 10/11/19: Added water landing/movement/takeoff details. 10/13/19: Added postscript. 10/15/19: Added table of contents. Reorganized flight/landing characteristics. Added detail to docking. Updated photos (10/5 changes), minor text changes. 10/16/19: Added "Reentry", minor edit to "Ascent". 10/22/19: Altered commentary on small TCSes. 10/23/19: Removed Z-4K battery after finding a way to mount the drills on the reaction wheel and still fit them through the cargo doors. Added small ore tank for symmetry in new location. (Cost reduced by 4.2k, mass increased by 0.675t wet but reduced by 0.075 dry. Battery capacity reduced from 5710 to 1710.) Updated cargo hold picture. 10/26/19: updated "Ascent" to reflect 1.8 aerodynamic changes. Redid Minmus test—new photo. Postscript: the action groups: 1: RAPIER toggle (on/off) 2: NERV toggle (on/off) 3: RAPIER mode swap & air intake toggle (open/shut) 4: All cargo bay doors toggle (open/shut) & small thermal control system* toggle (deploy/retract) 5: --- (nothing) 6: Drill toggle (deploy/retract) 7: Surface harvester toggle (on/off) 8: Fuel cell toggle (on/off) 9: Obtain all possible science, including crew report 0: AIRBRAKES toggle (deploy/retract) Lights: default (all lights turn on or off) Landing gear: default (all landing gear extends or retracts—note that this is NOT a toggle) Brakes: default Abort: The top cargo doors open and all parachutes deploy. It's possible that some parachutes won't deploy if the doors aren't already open; just press the button again. *(Note: the interior thermal panels are always on by default)

Brahe is a moon truck addon for Tycho. Both can fit into Ranger's Service bay. The XR project was built upon results the older X-84 Akkadian / Ishtar project: Fly to every moon and planet in the stock solar system as well as in the outer planets mod and collect science with three Kerbals. The take-off-weight of Ranger SSTA / Agamemnon Eve Lander Combo is 30 t lower than the Akkadian / Ishtar at 120t.

Here's to space on a budget. XS-01 Viper - upload pending- Viper is a lightweight, single use crew transfer system with a rapier and an ion stage. At 30 parts and 5.5t take off weight, it brings one Kerbal into orbit with 7.600 m/s dv left. This should suffice for most destinations in the Kerbol system. Fancy stuff like landing gears or parachutes is omitted. Just power up the engine and fly. TWR in orbit for the ion stage is 0.3, which is fairly reasonable. In order to not only bring pilots into space, it has drone core equipped. XS-02 Sparrow - upload pending - Sparrow is a light weight single stage to orbit concept with one rapier and one ion engine. At 6.3t take off weight, it brings one Kerbal to orbit regardless of profession. As the ion engine only has an TWR of 0.07 in low Kerbin orbit, getting somewhere is a game of patience. XS-03 Sparrowhawk https://kerbalx.com/Mephisto/XS-03-Sparrowhawk-RapierIon-SSTO-to-Minmus An improved version of the Sparrow, the XS-03 Sparrowhawk has significantly greater ranger and twice the thrust in low orbit. Now even with landing gear.The larger battery pack as well as the quad ion engines allow for sustained ion burns of app. 250 m/s. The TWR of 0.12 in LKO is fairly reasonable for ion engines. XS-04 All-Seeing Eye https://kerbalx.com/Mephisto/XS-04-All-Seeing-Eye The latest excrements in ore surveillance technology. Also knows your bad habbits and browser history. Comes equipped with ressource scanners, regular and relay antennas as well as repeateable science experiments. Powered by "a excrementsload of batteries and some spare ion engines", as the designers at the Kerbal Space Center put so eloquently. Comes with solar panels. Has roughly 15.000 m/s dV with ion engines, so evading it by moving to Dres or Eeloo seems kind of futile. Better use that incognito mode in your browser more often.... XS-05 Mighty Flea https://kerbalx.com/Mephisto/XS-05-Mighty-Flea-3t-Micro-SSTO 3t to orbit in a single stage. Kerbal included. No science experiments, no shenanigans. Mephisto. (To infinity and beyond.)
  13. This is poll where i'm wondering if you prefer building rockets, planes, or something else like SSTOs more in Kerbal Space Program.
  14. Já lançado! Para baixar o pre release siga para Thread de lançamento: Fala ai pessoal. Apresento a vocês meu projeto de partes em desenvolvimento. O Omicron, carro voador (ou space car). Meu sonho de consumo desde que eu assistia seriados de ficção quando era criança e continua até hoje. Juro que achava que quando chegasse-mos aos anos 2000, já teríamos desses na rua (no céu). E pelo menos um na garagem. Bom, já que ele ainda não chegou, aqui vai como eu o imagino, e com partes montáveis como cada um achar melhor. Com muitas possibilidades, para o gosto de cada um. List of things i still need to do (for full release): Solar Panel; Back docking port; Airbags & Floaters; IVA; Functional cockpit panel; Ejection system for seats and windows; Wings; Fine tuning parts (crash tolerance, temperatures, etc); Bons voos comandantes!

  16. Hello I decided to build a space station and send it to duna in order to finish my science tree in career mode. I already had a shuttle built, so I wanted to build the station in multiple parts and transfer the whole thing to duna rather sending one giant station. First part was the science module which consisted of only two mobile processing labs. The next part was electrical (batteries and solar panels) as well as the main engine and mono propellant (so no command module). After decoupling from the shuttle, it is being shown as debries and I can no longer track it to dock with it or to at least destroy it! https://i.imgur.com/UCNZXDY.jpg Is there anything I can do to save that or is it a lost cause?
  17. Hello! As you might have known, yesterday i made my first SSTO ever. And i thought i could do better, this is the result. Please tell me suggestions in the comments about how to design a better SSTO.
  18. Hello, i made my first SSTO today! (yes it's an awful desing, but i dont know how to do better) Here's the link to the image collection= https://imgur.com/a/FafC1GB And yes, it has a parachute but i didn't use it. (It's a drogue one) Also note that one of the white tanks is a LFO tank with the white skin, not a only-LF tank. Please send me tips on the comments so i can make a better SSTO next time. See ya soon!
  19. Just built a large SSTO with 6 Turbojets, 4 Rapiers, and 4 Aerospikes weighing in at around 132t fully loaded. It managed to escape Kerbin atmosphere on multiple tests with very few Issues. in atmosphere at around 2km above sea level it could easily cruise at 700+m/s with the turbojets thrust capping out somewhere around 250-300. I saved my game and left my computer for an hour to go run some errands and when I got back the SSTO's engine performance for some reason changed drastically. At 2000m above sea level the engines can't even achieve a thrust above 190 and the SSTO struggles to get past 300m/s. I have made no changes to the craft prior to its successful test flights and the weight in the editor has remained unchanged. Is this some sort of bug?
  20. AFAIK, the X-30 SSTO/TAV was supposed to just use air-breathing engines to reach Mach 25 and orbit, while the similar HOTOL SSTO/TAV would use both air-breathing and rocket engines, which makes sense to me because air-breathing engines are useless in space. so, how was the X-30 supposed to work?

  22. The KSP is developing a new extremely lightweight SSTO design. They need your help to create one! (I know this is probably a common challenge but it would be nice to revive it) Rules: 1. The SSTO can take off from the runway or the launchpad, but not from anywhere else (this will be noted in your entry) 2. The SSTO can be manned or unmanned (there will be two leaderboards for this) 3. The score is solely based on mass (the size of the craft doesn't matter) 4. No Kraken drives, use of eva packs (this counts as a second stage) or other cheaty methods 5. The apoapsis and periapsis of the orbit must be above the Karman line 6. The SSTO doesn't have to be able to deorbit and land itself 7. If it wasn't already extremely obvious, it is a Kerbin SSTO 8. As evidence, you must have a video or screenshots of key events in the mission with fuel gauges left visible (leave the UI on) 9. If there's anything you think I should add to the rules tell me (criticism and feedback will be greatly appreciated) Smallest Manned SSTO Smallest Unmanned SSTO 1. TheFlyingKerman (3.687t) 1. TheFlyingKerman (0.985t) 2. Vyznev (3.984t) 2. 3. 3. 4. 4. I will start to design a craft of my own soon!
  23. using only rover wheels get into orbit around any body, secondary thrusters can be used to keep the craft on the ground longer but not to increase the craft's acceleration directly. the tiers are: easy: use rover wheels on a moon to get into orbit around a planet medium: use rover wheels on a planet or moon with atmosphere to get into orbit hard: use rover wheels to generate enough speed to get into orbit around the sun good luck to all, this challenge may be impossible.
