  1. Very good tutorial, Khrissetti. To Mun step 5.5: Shut off engines as soon as the conic section display shows you\'re going to get an orbit, so you don\'t overshoot. (Just in case that wasn\'t clear.) Landing step 9.5: Last-second vertical RCS puffs (H key) can fine-tune descent speed, meaning the difference between a gentle landing and kablooey. This has saved my landers more than once. Landing step 10.5: As soon as you\'re down, turn off SAS and RCS. In their attempts to maintain your attitude, they can bounce and twist you into trouble. About return step 3? I\'m still working out the best method. If you aim straight for Kerbin, later path adjustments risk slowing you to the point that Mun grabs you again. Also, going straight down leaves you with more speed to burn off when you get there, and you don\'t want to slam into the atmo or overshoot because you ran out of gas. For those reasons, I aim 45 degrees behind Kerbin, so that Mun is 'throwing me back over its shoulder,' as I think of it. (See attached illustration.) This gets me clear of Mun sooner (as it moves on ahead and is therefore less likely to recapture me), and means Mun\'s gravity is releasing me to fall more than throwing me straight down. How does that sound?
  2. All you need to get a tidy orbit is to keep your nose pointed at 90 (east) on the navball, so maybe steering is the problem rather than navigation? What kinds of fins, gimballed engines, and SAS are you using?
  3. Attached is Newton\'s nifty explanation of how orbit works. A canon is on hill V firing canonballs to the right. Fire the ball slowly and it does move sideways, but gravity also pulls it down and it lands at D. Fire it a little faster and gravity still pulls it down just as hard, but it\'s also moving sideways faster, so the ball goes father before landing at E. Fire the ball somewhat faster, and as the ball travels, the earth curves away underneath it, so the ball goes even farther before hitting the ground at F, and faster/further still at B down there. But at a certain speed, the orbital speed, the earth (or whatever) curves away at the same rate that the canonball falls/flies. The ball really is falling (freefall), but will just keep falling and never hit the earth. Of course, this illustration pretends earth has no atmosphere to slow the ball down, but the idea still works if you just imagine the mountain sticks up out of the atmosphere. Newton. Figured this out. In 1687. 270 years before Sputnik actually did it for the first time. (So nobody gets into any kind of legal troube, I copied the picture from here.)
  4. Let\'s see the General Lee try this: 34.8km non-fatal rover jump. Screenshot #7: Liftoff, with one of my parked landers as a reference point below (just above the navball). #9: Cleared lander by 4 vertical kms. #12: Neilbles and Dudney reconsider the merits of the endeavor. Geofnard remains sanguine. #15: Touchdown, 34.8km from liftoff point on the cliff (minus the trig to correct for the reference point being 4km below the ellipse-section flightpath, whatever that would come to). #18: Woops, went over another hill before we could brake to a halt. I guess we\'re not done. I can see my house from here! And Kerbin and Mun! Yes, we flew so far that we watched the planet rise and had to adjust our attitude to correct for the curvature of the moon so we\'d land on our wheels. #20: Second touchdown 9.8km from first. #21: Lived to tell the tale.
  5. Leading cause of death among humans: heart disease. Leading cause of death among Kerbals: the M key is next to the spacebar.
  6. By passing in front of the first body, it starts off slowing you down. But perhaps by lingering low in its gravity well, you end up with a net gain?
  7. When you\'re rolling you can use the B key to apply brakes. I didn\'t know about that until somebody told me, too.
  8. However long it took, it was worth it. Plus, bonus points for using that bit of music from Serenity that always makes me cry.
  9. That\'s nice of you, but I prefer to go through days of rage and despair so that I can say I did it myself. Incidentally, your ship has wheels, but looks like you land it on its belly. What\'s that about?
  10. I want to recover my capules, too. For right now, all I can do is pretend that landing strut is a crane.
  11. All tidily sorted now. Achievements (rover parked by a monolith, etc.) : 103 Catastrophes: 52 Illustrations (of orbital mechanics and stuff): 16 Scenery: 240 Ship designs: 32 Knowing you don\'t care but feeling the need to post this anyway: part of the sickness.
  12. Tang and space food sticks. (Does anybody else remember those?)
  13. Considering that my best spaceplane can takeoff and fly but can\'t reach space or land without exploding, yours is aces. Seriously, though, yours is both cute and functional. I\'m jealous.
  14. A lot of players use it for that: fine-steering on the final descent. That\'s not my method, but it works for other people. However, I think kknight is talking about using RCS to propel his lander-rover? That will work, I think, but you\'ll run out of RCS fuel pretty quickly. A little fuel tank with the 50 unit engine will last a lot longer.
  15. Yep, those aren\'t the monoliths. You have more stuff still to find. (You don\'t need to go that far to find some of it!)
  16. I don\'t go as crazy with it as you do, but it\'s reached the point where I think I need to make some sub-folders and sort my collection so that I can find the one I want when I need it. For categories I\'m thinking: scenery, achievements, comical mishaps, the staggering awesomeness that is my ship designs (that one would have a lot of crossover with comical mishaps), and stuff that illustrates ideas.
  17. You liked it? I didn\'t find this helpful:
  18. It looks like much of the mass of your ship is below the RCS thrusters. If the force is off-center, it will push the ship to the side AND cause it to pivot around the center of gravity. Add another set of thrusters lower down, or move the ones you have so that they\'re around the COG.
  19. Oops. I wanna switch back. What are the original patched conics settings again, please?
  20. On the real one, the orbiter\'s engines are angled slightly to help counter the asymmetrical weight, as you can see here. I don\'t know how well that would work in the game, but if you\'re trying to make something similar, that\'s how the real guys did it. Otherwise, more (asymetrically arranged) boosters!
  21. If the lowermost parts on your ship are not too explodey (engines and fuel tanks I think are the most volatile), you can retract the struts after you land and just let it sit on the ground. Then it doesn\'t wiggle around or stroll downhill.
  22. All it takes is fuel. Getting it to be geostationary above a certain place is a little trickier, though.
