  1. Can't second this enough. Mechjeb is great for tasks that can be boring and monotonous once you've nailed them like flying to orbit, but used to early it can really hamper your learning curve. A friend of mine used it from the first day he played and then after one patch or another whilst waiting for it to be updated he basically couldn't play the game cause he didn't know how to do anything manually.
  2. Ctrl and Shift work just fine for me in docking mode put a pod with rcs fuel and blocks and nothing else, put it in docking mode and shift fires the rcs thrusters down to raise my pod, ctrl the opposite. I don't have mechjeb.
  3. Radiation doesn't have a temperature exactly it kind of is temperature. Temperature is a function of differences in thermal energy, generally something with less thermal energy feels cold, something with more feels hot, however the speed of energy transfer affects the temperature as well a book at 10C will feel a lot warmer than a steel block at 10C because the steel will more readily accept the energy from your hand. Energy always flows from the high energy to low energy system until an equilibriam is formed. As far as I know there are 4 main ways to do this, conduction, diffusion, convection and radiation. The atoms of any object above absolute zero (about -273C) vibrate, the hotter they are the faster and more vigorously they vribrate when you touch something your atoms bump into the atoms of the object and will either recieve or impart energy. This is conduction and is one of the fastest ways of heat transfer especially when the temperature difference is large. NOT applicable in a vacuum Diffusion generally applies to liquids and gases only, if I pour hot water in a bucket of cold water, some energetic atoms will pass on energy but some will also diffuse evenly into the water carrying their energy with them. NOT applicable to solids (ie people, engines w/e) or in a vacuum. Convection is similar think of something like a warm front of air being forced up over a cold front the energy/atoms all move in bulk. NOT applicable to solids or in a vacuum. Which just leaves us with radiation. As charged particles (which make up most of everything) vibrate they emit electromagnetic radiation and it is this which carries away thermal energy in a vacuum, it's a very slow drawn out process. As an example a person exposed to the vacuum of space will die within a couple of minutes but will stay warm for something up to around 18 hours.
  4. Try and have the boosters attached to the decouplers near their middles, otherwise they have a tendancy to swing inwards and take out your central stack, failing that you can use sepatrons to push them away once you have them.
  5. You would want to wait until minmus was at one of the two points in it's orbit where it crosses the same plane as the mun so you don't need to do an inclination change. You'd also want to leave minmus retrograde in regard to it's orbit to bring your pe down to the muns orbit.
  6. There is a sweet spot where heating is higher but so is drag so you decellerate faster leading to less heating overall. Deeper than this and aero/gforces/heating destroy you and above this you'll experience lower heating but it will last much longer as you're decellerating much slower and overall leads to more heating. In simple terms 1200K for 5 seconds is less damaging than 800K for 45 seconds (finger in the air numbers but show the point I'm making). Think of it like your oven, put in a cake at 220C for 5 minutes and it'll barely be warm, put it in at 180C for an hour and it'll be burnt to a cinder.
  7. I know you've said you're giving up, but if you do give it another try, record the attempt and upload it somewhere, we may be able to see from the video where you're going wrong.
  8. FYI For larger inclination changes it can be cheaper delta V wise to go into a higher slower orbit change inclination then drop back into the lower orbit.
  9. Aye, but where's the fun in that!? no worries
  10. How so? A TWR of 1 at sea level with RCS thrusters is equivalent to a TWR of 2.4 in a vacuum whilst under kerbin gravity, the mun has 0.166 the gravity so you multiply the TWR by another 6.02 and you come up with a mun vacuum TWR of 14.448 So to work out what a TWR of 1 on the mun is on kerbin you simply divide by 14.448. Which is 0.07 By which I mean is if on mechjeb or KER it states your kerbin atmospheric TWR is 0.07 then on the mun you will have a TWR of 1.
  11. RCS thrusters put out 0.42kn at sea level on Kerbin and 1kn in a vacuum. Knowing this means a TWR of 1.1 on the Mun is equivalent to a TWR of 0.08 at sea level on Kerbin.
  12. The only things you should do in any game are things you find fun and rewarding, though this is especially true of sandbox games. If you're playing career then a well piloted and returned spaceplane will almost always be cheaper than a rocket, otherwise there is no real reason to use them over a rocket unless you enjoy them.
  13. Indeed it is slow, but I'd rather do that than revert/quickload because my craft ran out of fuel with a 71km orbit
  14. If all else fails point the rocket retrograde and have the kerbals get out and push with their jetpacks.
