  1. I couldn't check, the box that tells you about the crash blocked everything and couldn't be dragged. However, I got the deorbit point dialed in right, put it in the ocean within sight of KSC at about .2 m/s (chutes plus the rocket) so it didn't bobble at all (the usual cause of water breakups I've seen is the rocket going too deep and being destroyed after the rebound), it looked perfect. Then it slowly tipped over and every bit of the rocket that mattered was obliterated, I was left with a pile of engines and fuel tanks. It seems completely insane but I think the only way this desi
  2. I decided to try something. I took the wheel off and put the very same wheel back on the outer part (so now there are multiple wheels)--I never picked up a different part. Now it steers properly. The only thing I can think of is roundoff--maybe the wheel's rotation is being rounded to zero. It does turn out I need more power for some reason, though--the battery drained while doing nothing in orbit. I guess those tourists had too many lights on. And now I'm really confused!! It didn't come down exactly where I planned but I thought I was doing ok. I put it in the ocean as intend
  3. I do have a much heavier vehicle with the same wheel but this is not a case of being out of power! That was my first thought, but I looked, the battery is nearly fully charged. I expect it to turn slowly but it's got 7 minutes to turn maybe 10 degrees for the circularization burn. I do not believe I need panels--the battery will be used to orient for circularization, but then recharged by the circularization burn. It will be used again to reorient, partially charged by the deorbit burn and then probably fully charged when I burn to get it down to opening velocity (aerobraking alone won't s
  4. (Note: I've been away from the game for a while, maybe something has changed that's messing with me.) I have a probe core--the OKTO2, tweakscaled up to fit. I also stuck Jeb on board after the first flight got stuck. I have power (although no way to generate it--this is a tourist hop, it's only staying up a fraction of an orbit.) Note that the engines gymbal if I attempt to turn the rocket. I have a reaction wheel. Furthermore, I have two designs. The first is the core of the rocket--chute, core, wheel, passengers, fuel, engine. This flies fine and has successfully
  5. How is that a balance lever? What I'm suggesting would simply reduce the number of times you have to tend the lab, it wouldn't change the output. It's just a reduction of micromanagement.
  6. Note that I said the extra should be a buffer, it shouldn't participate in the yield calculations. I realize that if it did it would certainly be unbalancing. I don't see any balance issues in having an infinite holding capacity for output. That's simply a matter of not having to tend it as often.
  7. Yup. Some time ago I tried the science lab route to massive science. I had already grabbed all the science from the Kerbin system so I went to Duna (or was it one of the moons? I forget.) I had a rover with all the science instruments and Bon Voyage to guide it. A separate mission landed a science lab. Gather all the science, upload to the lab, launch another copy of the science lab rocket, unmanned. When the lab was done the scientist goes next door to the next lab, repeat the cycle. Then I discovered the mod that allowed you to use the extra science to improve parts was incompati
  8. Yeah, I had no idea there were hab time multipliers there, either. The only way I knew to get high hab time was something like that earlier rocket studded with observation portals, or else a bunch of the big rings.
  9. I do have a problem with how hab time works--we need some bigger parts. Look at your example of a 5-year ship. There are a lot of parts on there to get that 5 years. I'd like to see some bigger things that provide the same benefits for similar cost & weight but using a lot fewer pieces. If crew capacity and bonuses were altered by TweakScale that would probably do the job, although I would like to see an in-line module with bonuses.
  10. It's not actually your center of gravity that matters, but rather the angle between the ground and the center of gravity. The smaller the angle the more stable the rover. Putting your mass low helps but it also helps to make your rover big. It will be a pain to haul to orbit but it's a lot less likely to crash. Also, if you're willing to spare the mass & power, use reaction wheels. Bring along a pilot or probe core capable of running SAS. With SAS on it will use the reaction wheels to try to keep the rover from flipping. I've taken rovers with big reaction wheels over terrain wh
  11. I'm not contradicting myself. On launch a rocket goes straight up, then soon tips with the rotation of the body and accelerates to orbit. This is the lowest energy trajectory, you want to do the exact reverse to land with the least fuel. The first burn puts your periapsis a bit above the point where you want to have killed your horizontal velocity (the reverse of your circularization burn.) You then come in, lighting your rocket at the point it will kill your horizontal velocity over your target. This of course means you end up lower than the orbit you were in, hence the reason your peria
  12. I don't think keeping the downward momentum under control is what you want. You want to leave the burn for as late as possible. The ideal landing is a gravity turn in reverse. Without knowing exactly how the rocket will perform you can't do that precisely, though, so you're going to need to allow some margin.
  13. A "transfer window" normally refers to a situation where you have three bodies involved. The math is imprecise and much more complex than what you are thinking of with a Hohmann transfer. For a Hohmann transfer you simply need to find when you're at a point directly opposite where your target will be in half an orbit. (If that gives a negative solution you missed it, look for the next such point.) Things like Transfer Window Planner and the similar functionality in MechJeb, however, are looking at a more complex problem. 1) Your target is in another SOI. The simple math of a
  14. Stages are only recovered when they go below the IIRC 22km line. A stage that doesn't go that low will simply remain in "space" (even if it is actually orbiting entirely in the atmosphere!) and not be recovered.
  15. I would like to see a few changes: 1) The higher the Kerbal's level the longer they should be willing to be on a mission. 2) The submarine has a lot of people--I think that matters. The more Kerbals around the longer they should accept the situation.
  16. I can't address whether the propellant goes down or not but your evidence doesn't prove it. The jetpack contains a ridiculous amount of fuel in stock. You can get to orbit on Minmus with your jetpack alone, no need to refuel. One refueling (and note that a canister is supposed to provide enough for two) will get you to orbit on the Mun. (Note that the Basic Orbit mod will make it much easier to do this, it lets you see your orbital parameters in the close-up view.) In versions past I have done orbit-Minmus-orbit with one fuel tank and orbit-Mun-orbit with two. Admittedly, I'm not goo
  17. Later messages seem to indicate you solved your problem (there's a reason it's recommended to uninstall old versions of mods before installing the latest!) I do have a comment about your mission profile. This sounds like you're just hauling tourists to orbit. It also sounds like you have decouplers. Assuming you have radial parachutes may I suggest an alternative design that would provoke outrage at NASA but it will fly: Put your pilot in a capsule, put your tourists in the crew module (meant for aircraft but it works in space), take a heat shield and invert it and stick it on the nose
  18. When you see things set up in powers of 2 like this you should automatically think bit flags--you can add together any combination of them and yet tell exactly what numbers were added together. It's the most efficient method of packing such information and given that the author used it pretty much implies there was a lot of data to keep track of. The storage units that such things get stored in have standard sizes of 8, 16, 32 or 64 flags, each of which uses twice as much memory as the next smaller size. Also, KSP mods are written in C# and while it supports 64 bit unsigned values they
  19. Are you sure the stage isn't still up there? KSP's destruction threshold is well below the top of the atmosphere and objects on rails do not experience drag even in atmosphere. If your periapsis is above I believe 22km the stage will remain in orbit--even if that entire orbit is within the atmosphere! (Careful--remember that you can't switch away from an object in atmospheric flight. Switch to such a booster and you have to stay with it until it burns or goes splat.)
  20. You made a typo and said KIA (a Korean carmaker) rather than KIS. I decided to have some fun with it.
  21. Well, if you want to install a car into a spaceship you need the SpaceY mod!
  22. You simply set Steam to load the "beta" that is 1.5.1. Now, if you're talking a pirate version, it's too good a game for that, walk the plank!
