@grafdog1138 What does it typically look like? You can contact me here. IMPORTANT NOTE: These Charts are for Circular Orbits. ) 300 days Elliptical < 48 Mm Low Orbit. You can use these values when editing the save file. The first step is knowing the period of the minimum orbit at which the satellites will see each other. Getting the Period from the semi-major axis, Getting the altitude through the desired period, N-Satellite Constellation Minimum Altitude. ©2020 Take-Two Interactive Software, Inc. Just make sure to bring some extra batteries for them- best of luck and remember there's no shame in alt+F9 'till you can stick the landing! I'd normally aerobrake using body lift from the rocket to maintain a ~7km altitude, but for a first trip I'd recommend just using the Skipper stage to bleed off extra speed in the upper atmosphere (down to 1000-2000m/s), and then use it to control a pleasant descent, finally dumping the thing a little ways off the ground.  The 3 terrier craft will be much more pleasant to land! SMA = 8× the body radius has about 3× the margins of error mentioned above). Remember here that the sine of an angle is the relation between the opposing (o) and the long side (hypotenuse h) of the triangle while the cosine is relation of the adjacent side (a) to the hypotenuse. Wait till Kerbin and the duna are somewhere around a quarter orbits apart from the sun. The problem with a flyby with intent to return the crew is that you're guaranteed to have a bad transfer window, either from Kerbin or from Duna, so you need to be prepared for a multi-year mission duration (if you play stock, that's not a big deal, but a life support mod will really complicate this) -- and this ship barely had the dV to use a gravity assist from Duna to get back to Kerbin (and was fortunate that Ike stayed out of the way).  I'd consider it pretty much the minimum crewed Duna mission.  In my case, the mission duration was around four years before reentry (of course, minimum even if you have the dV to capture and wait at Duna for a good window is close to three, so one extra year wasn't that bad). To transfer to Duna, you need enough orbital energy to kick yourself out of Kerbin orbit and raise your apoapsis to Duna intercept. KSP Stock Space Shuttle by _ForgeUser18393701. A scientific Calculator gives us: If the following mathematical statement is true the satelites will connect: If your aim is to only create a comm network without nesessarely connecting it to Kerbin, other than for Kerbol or any other body you can always get by with a single HG-5, possibly at the expense of signal strength. Easy to use here means a time that while a placed satellite in its final orbit will perform 2/3 of that orbit the satellite carrier being parked in a lower orbit with the apoapsis at the target altitude will perform one orbit. 60 km Surface. While these parachutes won't slow you down enough on their own, a little kick from the engines just before landing will ensure you don't turn your trip into an extended impact test. With higher or lower settings your results will differ. For a Duna trip, the core rocket would be composed of a skipper followed by a set of 3 terriers, the outer two staged on radial decouplers (everything tuned to TWR ~1.5). Some extra reaction wheels really help at this stage. For a first visit, I'd recommend having the periapsis at ~10km off Duna's surface. Elliptical < 13600 Mm Low Orbit. It's like deploying relays around Kerbin when you want them so far apart but Ike will destroy anything that gets too close. Make sure to set them to open as high as possible in as low pressure as possible! Intercept. Please consider starting a new thread rather than reviving this one. Also notice that if you manage to explore Duna, you will also be able to explore Gily (its even easier IMHO), and the lander design used in Duna don't need much adaptation to also work in Eeloo, Dres, Moho, Vall, Bop and Pol, granted reaching those destination is a bit more of a issue. The escape velocity is how fast your spacecraft will need to go in order to escape the origin body's sphere of influence and go onto the intercept trajectory to the target body. In a 3-Satellite constellation 3 satellites are evenly spaced in a triangle with each one holding a 60° angle towards the other satellites. Making Ike look like its slinging left and right when Duna rotates. Mission says 'Attach a new part to satellite in orbit of Minmus.' Leur basse altitude permet plus d'aérofreinage, et elles sont plates, ce qui en fait d… However, I was wondering, in what circumstances does your vessel bounce its signal off a relay satellite? Inspired designs on t-shirts, posters, stickers, home decor, and more by independent artists and designers from around the world. Use the appropriate relay antennas. So in the course of a science game of mine, I've become really, really tired of playing around in my own little corner of the solar system. Then you can correct inclination and eccentricity of each satellite using the appropriate burns at the appropriate locations (mess around with maneuver nodes). By sliding the maneuver node around, you can find the time when the burn will put you into Duna's SOI (you can find your window). Hence you need to be at an altitude of the radius to be visible. The question is, what does it take to get there? Alternatively when coming from a higher orbit the placed satellite might do 1.33 orbits while the carrier makes 1 orbit with its PE at the target altitude. You know, the poles are nice to visit... bleak, all be. Clusters of kickbacks and drop tanks peal off the thing as it screams straight up to interplanetary space. Dres. Inspired designs on t-shirts, posters, stickers, home decor, and more by independent artists and designers from around the world. Instead of looking at the periods of the orbits, you will look at the distance between satellites. Be sure to use Relay antennas if you are not playing with the additional ground stations, because they will need to relay to each other to reach KSC. It's not going to work well, though. It's totally possible with lower upgrades, but this is the point where you won't be fighting the system. Calculate the resonant orbit needed for a carrier craft to inject craft it carries, like satellites, into equidistant positions of a shared circular orbit. Notice that, since you are playing in science mode, most of what I bring to Duna (or any other place) will have little or no use for you. The recommended procedure is to first get the satellites into a circular orbit with the correct semi-major axis, paired up at opposite sides. = Masaq’ Orbital, remembering the Canterbury. × Now that we know the minimum time satellites visible to each other take for one orbit we can select a higher time interval, and hence a higher orbit, that will allow us to place the satellites evenly. The simplest 4-satellite constellation is the equally spaced equatorial constellation. Hence it can be divided into four squares with the connecting point at the planet's center and a side length of the radius. 725-730. Start with a simple one, Basic DeltaV just make the calculations for deltaV, TWR, burn time, Isp, mass and thrust and display it next to the staging sequence in the VAB/SPH. Result: There is nowhere "safe" to put a satellite in low or even medium Duna orbit. Their low altitude allows for more aerobraking, and the flatness of the terrain makes them easy but boring landing locations. 6 (1985), pp. The long side hence will also be the distance of the satellite to the center of the planet. Keep it simple, Duna is just like going from the Mun to Minmus, on a much larger scale.Â. The adjective is dropped when it is clear what type of satellite is mentioned. so we can get a feel for your building style. Enable a big science mission to Duna and also Ike! can then be used on the coordinates that you calculated. Oct 11, 2020 - Explore Roam Langevin's board "KSP Designs" on Pinterest. Duna is the fourth planet from Kerbol and the fourth-largest planet. The “Injection Δv” value is the delta … Paste as plain text instead, × Given the fact that I play with TAC Life support, RemoteTech 2, KSP Interstellar and few other mods (no deadly reentry tho), makes missions much more complex, but infinitely more fun. ⁡ With the additions in Communications networks in 1.2, getting continious communication in any given system is an important factor. The one for Ike usually is good enough for the science in orbit. Manned or unmanned, I'm interested in both types of mission... but what does a typical Duna mission look like, and is it complicated? And that's about that! It will be over-engineered and more expensive than it needs, but it will do the job. None of it is particularly complicated, you just need a bigger rocket to cover your fuel expenses due to the greater distance between Duna and Kerbin than Kerbin and the Mün. It really only automatize calculation you may do it yourself or with an online tool, it barely change anything. Make the burn, and a couple weeks away from Duna, make a 'correction burn' manuever node to put you on course to whatever part of Duna you'd like to visit. Pop on out, enjoy the fresh rarefied air! Then again, at least you get a ballpark idea of what your rockets can do. Kerbal Space Program. For facilities, I consider the following to be a good point: Launchpad level 3, VAB level 2, Tracking station level 2 and Mission control level 2. All orders are custom made and most ship worldwide within 24 hours. cos(60)=0.5=1/2. 8, No. The period can be calculated from the following formula: Inserting the semi-major axis derived from the earlier step will give you a time in seconds, which I recommend to convert to HH:MM:SS for ease of use in the next step.
