  1. Even the extended hangar wasn't big enough for my purposes...Luckily changing "config version" to 3 and hangar scale to 2000 made it work. It will be 1600 m long when fully scaled up.
  2. It shakes when you approach a glowy thing.
  3. Somebody should make an artwork of all the Star Wars characters standing together, and as their respective actors die they become blue Force ghosts in the picture.
  4. I played through it today and liked it. The pineapple is cute and odd.
  5. Because kilometer-scale flying metal warships are cool. Another note on my experience with the movie: I got super excited when they gave the order to activate the hyperdrives on the Death Star, because for some reason the idea of seeing something that big with the radiating blue lines was really exciting, but then they didn't show it.
  6. It's ok, they'll have about four years notice before they all die, so plenty of time to send that last voice message home.
  7. Rubbish? Take any arthropod and you will see why they've been so successful. Spider silk, beetle wings, wasp nests, they're all marvels of evolution and deserve respect, no matter how much you hate being around wasps.
  8. Planes are for seeing how close you can get to the ground at Mach 2 without crashing.
  9. Ah, well in that case...test away! I still think two minutes of calculator time is a lot easier and almost as good as twenty minutes of flight testing, though.
  10. It may sound hard, but all you have to do is put in the right numbers and hit enter, and you'll know your exact delta-V. It's actually quite straightforward. Let me give you an example. We'll use a simple ship: a Mk1 command pod (0.84 t), an FL-T800 fuel tank (4.5 t, 360 LF, 440 OX), and an LV-909 engine (0.5 t, 345 Isp). We'll assume it's in a circular 72 km orbit around Kerbin. Now to calculate delta-V: The mass of the ship is 5.84 t (can be found from map view). The Isp of the ship is 345 (can be found from engine's right-click menu). The ship has 360 units of Liquidfuel and 440 units of Oxidizer (can be found from fuel tank's right click menu). Now use this equation: A little bit of button punching later, and: dV = 3908.922 m/s 5. Use a delta-V map to find where you can go! So, that ship could get to Ike and back with plenty of fuel to spare provided you manage to conserve 50 EC for two years and land upright with no legs.
  11. It's actually a lot faster to do the math than to fly all the way to another planet. You can even use this equation in flight: For LF/OX: dV = 9.81 * Isp * ln(current mass / (current mass - 0.005 * (# units LF + # units OX))) For nuclear: dV = 9.81 * 800 * ln(current mass / (current mass - 0.005 * # units LF) It'll save you hours.
  12. It's obviously blocked by the wheel. You need to use larger wheels to give the hatch more room.
  13. Today it rained almost all day. The trouble is, at this temperature it all freezes on the ground, creating a layer of ice a few millimeters thick that only serves to make your life suck. It's literally an ice rink out there. Luckily it's stopped now, but I really hope it stays above freezing tonight and melts off. This is why we have salt trucks...
  14. I imagine a universe where paper currency means paying for things with their value in paper.
  15. Delta-V is a measure of how much your rocket can accelerate before running out of fuel. The equation for it goes like this: DeltaV = 9.81 x Isp x ln(full mass / dry mass) Isp is a measure of how quickly an engine consumes fuel (higher is better). You can find this in the part description in the ship editor, or in the part's right-click menu. Full mass is how much the rocket weighs when it's full of fuel, and dry mass is how much the rocket weighs when it's all out of fuel. The rocket gets lighter as the fuel drains from the tanks, so the dry mass is less than the full mass. You can calculate the Delta-V of a rocket stage in the ship editor by looking at the mass in the engineer's report, the mass after draining all the fuel tanks, and the Isp of the rocket engine it uses. (You probably only have one type of engine on your ship. For engines with different Isps it gets more complicated.) Repeat this process for each stage in your rocket to find the total Delta-V. Once you know know your Delta-V, you can use a Delta-V map to find out how far your rocket can go on an optimal route. Here is a nice map: So, a ship with a Delta-V value of about 3500 can accelerate 3500 m/s in zero gravity, and will be able to reach Kerbin orbit. A ship with 5300 m/s will be able to land on the Mun, but it needs an additional 900 m/s to be able to return to Kerbin. I calculated all that simply by adding up all the numbers between Kerbin and Mun. A round trip to Duna would require about 8200 m/s, eyeballing values for Kerbin and Duna because the atmosphere can help or hinder you depending on the design of your ship and how you fly it. The other thing to consider when going interplanetary is the phase angle. You need to have both the origin and destination planets aligned precisely to get to where you're going. Here's a diagram showing what angles you should use: And here's a diagram I made showing how you should burn when leaving a planet: Now that's a lot of information, and it's no surprise it doesn't all make sense at first. It is rocket science, after all! My best piece of advice is the simplest one: Just try it. See what works and what doesn't. The only real way to find out how to do interplanetary missions well is to try a few, find the issues, and try to fix them in the next runs.
  16. Ok, but writing "Happy Holidays!" in the sky with contrails?
  17. I believe this can be simulated using EVE by putting clouds at ground level. Try EVE or SVE and see if there are dust clouds on Duna. If not, it's probably not exorbitantly hard to add some.
  18. And that's perfectly fine, everyone gets their own choice. That's what voting's for, right?
  19. A slightly less papery version. Fun fact: that whole assembly (minus Kerbals) is one single ship, with the 2.5 m pod being the root part.
  20. souplogsoup waiter = waiter. Is that what you meant? Waiter, there's a bionic hand in my soup!
  21. Gets nyan.cat Inserts heavy water
