  1. Ike is too Easy to intercept

    Today I took a spaceplane and rode it to Duna. in the process of one maneuver, I entered and exited Ike 4 times! I am wondering if this is normal.
  2. Hi guys, So I was wondering, Because I have already went to the mun and minmus once (new career save, don't ask), I was wondering how much DeltaV it is to Ike and back. I've already been to other planets in my other Sandbox save, but never Ike. Also, is an Eve gravity assist a good idea? I have a Duna window in 71d, and an Eve window in 1y 120d. I also have critical contracts lying around, won't they get expired? Regards, Mabdi36
  3. Hi all! The short question: I'd love to hear recommendations on orbital altitudes for a refinery operation that will mine ore on Ike and refine it in Dunan orbit. The longer explanation: For the last week or so I've been playing in Sandbox, working out how to most effectively set up logistical infrastructures all around the stock solar system. I started by setting up a full-coverage Comm relay and ScanSat (the mod) network around every body on the stock game. I've done all this before, of course, but never as methodically and efficiently as I'd like. So far the four inner planets are covered, and various satellite carriers are nearing their destinations at Dres, Jool, and Eeloo. Now I've turned my attention to setting up fuel depots and ISRU operations, and have two flotillas of fuel stations, mining landers, in-system tankers, interplantery tankers, etc. headed to Duna and Dres. All un-Kerballed and drone-controlled, but with enough modularity to be turned into crewed vessels in the future. (Before it's mentioned, I know depots and ISRU aren't necessarily the easiest or most efficient ways to explore the system, but for the purpose of this save game, that's what I'm playing with.) I already have a clear plan for Dres; with an ore miner tailored for landing on the planet and another dedicated to the asteroids surrounding it. They'll bring raw ore to an orbital refinery/tankage station. The reason for this post: I'm not sure exactly what I want to do at Duna. The mining lander is large (by my standards) and can bring 10,000 units of ore from Ike to anywhere in the Dunan system. The depot will refuel Kerballed missions to Duna, and a few re-usable Duna Lander/Ascent vehicles that will remain in-system for surface explorations. It may also be used to send re-fueling tankers further afield, particularly to Jool, though a full Kerballed expedition to that system is still only a drawing-board notion. SO... any suggestions, tips, or other observations? Specifically, will I be better served to keep the main Fuel Depot/Refinery station in orbit around Ike, or should it orbit Duna? If the latter, will a high (near the SOI margin), medium (outside Ike's orbit), or low (inside Ike's orbit) altitude work best for my purposes? Keep in mind the station itself has no propulsion, but is configured so the Mining Lander itself can propel the entire depot (and is in fact doing that right now, toward a Duna intercept in a few hundred days). There are also several fuel carriers around Duna (most of them leftovers from the Comm/Scan satellite missions) that can move fuel from the depot to vessels that need it. I'm asking not just in terms of absolute efficiency (as in launch costs and fuel consumption) but also in terms of my convenience and "playability" (i.e. avoiding days-long warping to rendezvous various vessels from high orbits), and finding a satisfying balance between the two. I hope I've laid out enough to explain what I'm looking for in terms of feedback, without droning (no pun intended) on too long. Note: I'm playing with a smattering of mods, but mainly for aesthetics. All my craft are (virtually) analogous to stock vessels, so a full mod list doesn't seem necessary. Beyond that I rely heavily on KER and KAC to design and keep track of all the (40? 50?) missions ongoing right now. Your thoughts appreciated.
  4. Screenshots of Duna

    I was sening a rover to Duna and i saw this so i tought it would be good to show it Tell me what you think about them
  5. The science behind Ike!

    Ike is a relatively large moon of Duna. But what does such object does around Duna. Today we will figure it out! One of hypothesis is that Ike was formed with Duna because it’s orbit is stable and low. It is made of silicates and some kind of dark material. Perhaps there is not so much craters like on Minmus. So what kind of material is Ike made of? Honestly I don’t have any clue…. But lets imagine that it is some kind of flexible material that can make craters smooth. But how does this kind of material form? And where did it come from? But what if Ike was formed by a collision. A lot of material just flew away due to Duna’s low gravity. And some that stay formed a low-density object. But the orbit is so stable and almost equatorial. How? Maybe because of odd angle of the collision. (for a collision angle equator is an oddity) But what if Ike had really low density. And some of the material just escaped and then fall on Duna leaving nothing but what we have now…. The other and last hypothesis of mine is that Ike is a trail of volcanism that had strong appearance on Duna. But as how can we see, now Duna is geologically dead planet…. I hope you will appreciate my attempt to be interesting! I will be very happy if you will help me find a better hypothesis!
  6. Why? Enchanted by tales of "reactionless propulsion", the folks at KSC have invented the momentum tether, an enormous device designed to spin and fling kerbals from one orbit to another. I'm certain it will be a safe and pleasant way to travel. Rules Create a device to spin+fling Kerbals from a low circular orbit around Ike (13km or as close as is convenient). Spin it up and fling your plucky astronaut to their destination! If you miss but are close, use a maneuver node to figure out how many delta V you were away from your trajectory. If you're within 10% of the listed deltaV for the trip, it's close enough! Kerbals have EVA packs, after all... Additional Rules 0. Have another trip in mind? Fling it and I'll add it to the list! 1. Informational mods are ok, as well as any mods which won't effect this challenge. FAR is a-ok! 2. You can use cheats and hyperedit to get into low Ike orbit, but they're off limits for spinning up and flinging. 3. You can use rockets to spin your reactionless-propulsion tether. I like irony as much as the next fellow... 4. Rampant saving and reloading is expected! 5. Screen shots or videos are enjoyed but not required. Kudos you can earn for your spot on the leader board : D Stuck the landing >:) Bounced Kerbal off a surface at greater than 20m/s (physwarp helps) (>'.')> Hauled it out to Ike, legit. Destinations (from Ike) Duna reentry (130m/s) Interplanetary resonant orbit for gravity assist (~250m/s resonance pending) Vertical landing on Ike (340m/s). If your apoapsis is under 15km, use EVA propellant to arrest your vertical motion, set your navball to surface and have less than 34m/s horizontal surface speed. Kerbin Reentry (500m/s) Dres Flyby (~800m/s, but changes with the year) Kerbol Escape (~2750m/s) added by @TheGuyNamedAlan Have another trip in mind? Tell me the starting orbit and destination, and I'll add it to the list! Silly Introductory Video Leader Board LKO to Mun @Baricus chose to go to the moon and do the other things not because they were easy, but because they were Kerbal! An epic fling and gravity assist sent Alan Kerman careening halfway to Moho. LKO to Resonant Kerbin Orbit @Baricus lined up a fling-to and return-from interstellar space. The krakens were so bewildered and astonished, they apparently decided to KO Baricus' computer. LIO to Duna >:) @DoctorDavinci created the mythical staged tether to let Valentina headbutt Duna at a harrowing 180m/s. Both Valentina and Duna survived the encounter. : D @DoctorDavinci followed the hallowed KSP tradition of MOAR by using a 3-stage tether to fling Jeb to a soft landing on Duna. LIO to Resonant Duna Orbit LIO to Ike : D (>'.')> @LaytheDragon with a heavy-duty mk3 tether landed the relieved Navy Kerman gently on Ike. : D @Drone_Kerbal rocked it oldschool in v1.05, tossing Leaberta Kerman gently down to Ike. The same system should also be able to get her back to Kerbin! LIO to Kerbin LIO to Dres LKO to Kerbin (>'.')> @LaytheDragon spun 'till the tether exploded, flinging two kerbals safely back home. @DoctorDavinci left an entire ring system around Kerbin with 4 stages of tether flinging Jeb to greater and greater heights. Reentry turned out to be a bit of a doozie, though. Badge!
  7. Duna Explorer Mission

    After every KSP update, I start a new career mode game. Currently I've built and flown my Duna Explorer mission. The ship below was built and launched to orbit over 3+ launches. Not shown is the unmanned refueling vessel and the crew transport vessel. This trip took 7 Kerbals to Duna. Left 3 in the science lab in orbit around Duna for science! Landed on Ike as well. And returned to Kerbin orbit, ready to refuel and go on the next mission. Wondering if I could take this to Jool.
  8. I have a base on Ike, but I can't use RCS to fly? It's as if Ike has the same gravity as Kerbin? Anyone else experience this?
  9. My First Trip to Duna

    Hi I have been playing KSP for a while now, but never gone further than the Mun or Minmus. This is version 1.05 Moderate difficulty career mode. I had a short break from KSP before attempting this..... I think I was a bit rusty! Please feel free to comment on the Kerbaling as well as the Lets play style! Thanks for watching!
  10. A very long EVA

    So I was on Ike, and my lander can started to spin and spin and I decided to record it. I thought wat if I EVA and this happened, i could escape Ike, put me on a sub-orbital trajectory of Duna, and land on duna alive, only using the EVA suit. Check it out (it's a comedy video also): <Removed by moderation team> Tell me what do you think!
  11. Hi there... Who can build a manned lander that will go to Ike, orbit Ike, land on Ike, plant flag and take surface sample, return and land safely on Kerbin! Rules at launch: - 40 parts or less total. - 12 meter max height. - 31 ton max weight. Would be fun to see your designs!
  12. My highest aim is to a collection of lessons and anecdotes learned the hard way from exploring beyond the Mun. There's some humor along the way- I hope it's appreciated. By now in my first career I've planted some flags, made some gravity turns, even scribbled some maths, but nothing could prepare me for the long journy of the Ike-razy.. In hindsight, it's over-engineered. I've been holding onto this idea of a re-usable lander for a while now. First I built a 10-ton Mk2 lander before I had the full-size docking port unlocked...First words of advice: Clamp-o-Tron Jr. is not a good option here unless you like maneuvering with a jelly noodle. So anyway I'm headed to Ike with this new 4-ton lander and a good crew now that I have me some humility, and here's the thing about my new clever lander: Make sure your CoM is spot on when something's riding the nose of your rocket! I thought it was good enough...but it was only good enough to keep me drifting southward throughout my ascent...needless to say landing was a bundle of joy as well. So Jeb is stranded in LKO at the moment and before I realized I was going on a three year trip, I figured he'd be fine. So I took Val, a scientist, and an engineer...or so I thought. Kerbals are tricksy creatures, always double check your crew manifest in between VAB edits. I'm not saying they pulled a switcheroo on me...but I'm not saying they didn't either. The end result was I took Val and two engineers to Ike and back, so much for that science grab... I'll gloss over the nitty gritty, there's lots of tutorials for that...I hit my window, escaped Kerbin, I even made a sweet aerocapture around Duna that helped me return to Kerbin with 1000 dV (almost 3x my planned margin!) So here I am in orbit of Ike...minus 1 RCS block and my lander's solar array...WOOPS! Yeaaaaa...when you're planning an aerocapture, don't skimp on retractable solar panels!!! Or just don't extend them? I dunno...there's a lot of details here. Now, the real mistakes come out...Probably don't cut corners on RCS when you're planning some interplanetary docking business either. I may have decided I didn't need RCS on my lander to dock it which, strictly speaking, you don't. But, especially when you DO put monoprop on it...just add the thrusters. Your one pilot will thank you when they don't have to EVA several times to get the un-stabilized crafts situated before docking. So I docked this sucker with an empty lander floating through space and an asymmetric RCS arrangment. I'm almost done, promise. Here I am on Ike, and then I have one thought to share about return. Pretty snazzy low-tech lander right?'s gone now. To my friends comtemplating interplanetary adventures for the first time: Returning an object to a Kerbin orbit that you actually WANT it to be in from a Hohmann transfer without hard. Even with the 1000dV I returned to the Kerbin SOI with, There was NO WAY I was putting that glass house into a reasonable orbit...I jettisoned it and let 'er burn!! So, tl;dr, I like to learn things the hard way, and bite off more than I can chew. Learn from it, laugh at it. I thought I'd contribute something to the forum, it's been a huge help to my space program! To anyone good reading for laffs, I'd love build and maneuvering advice!
