  1. Indeed! Thank you good sir, I appreciate the response! -ODSTalex
  2. This is my first kOS program. Its just a small program for extending the landing gear before landing and opening any solar panels after landing. Wait Until ALT:Radar < 50. Gear on. Wait Until ALT:Radar < 0.7. Wait 10. Panels on. Print "Lander Has Successfully Landed!". To Use: Just run before deorbiting.

  3. mmm... I have had the same problem a few times, you may want to try making sure auto warp is on. Also try making sure that the Smart A.S.S is off. If none of that works try reinstalling Mech Jeb. Hopefully this helps. -ODSTalex
  4. Hello! Sorry for lack of updates, I have been a deadly combination of lazy and busy. I hope to have an update in the next few days. Also I have made a post in the "General Add-on Affairs" section if you want to take a look at it here is a link: http://forum.kerbalspaceprogram.com/threads/72454-Mech-Jeb-Guide?p=1020700#post1020700
  5. Hello, I made this for a friend and figured that other people may have some use for it. Criticisms welcome.

  6. thanks a ton! although now I feel like a bit of an idiot.... but whatever the case thanks for the response, it helps a lot.
  7. thanks for the tip, I will look in to it.
  8. I'm having some difficulty with finding my orbital velocity using the following equation: V² = GM((2/r)-(1/a)) Where “V†is the orbital velocity. “G†is the universal gravitational constant, which should be 6.67*10^-11. “M†equals the mass of the object that you are orbiting (for Kerbin it should be 5.2915793×1022kg). “r†is the current distance from the center of gravity of what you are orbiting. And “a†is your orbits semi major axis. The problem I'm running in to is that when I plug these numbers in to the equation, along with the parameters for a 100km circular orbit I run in to problems. V² = (6.67*10^-11)(5.2915793×1022)((2/700000)-(1/700000)) V² = 5.153045754*10^-13 V = 0.000000718 I don't think that the orbital velocity of a 100km circular orbit around Kerbin is 718 nanometers per second. help would be much appreciated. thanks, -ODSTalex
  9. yeah, I tend to make mistakes like that a lot. thanks for the correction
  10. ah, I see, that clears up some confusion I had while learning this. thank you
  11. Hello, ODSTalex here. I have just recently joined the KSP forums, and I was hoping to get some constructive criticism on a bit of orbital mechanics I have been learning. I plan to post here semi regularly with new pieces of orbital mechanics as I learn them; so please feel free to criticize and otherwise give me tips on orbital mechanics as you see fit. Thank you. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Finding Your Semi Major Axis: Finding your semi major access is very easy but quite important. To find the semi major axis of any orbit your simply find the average of your Apoapsis and Periapsis like so: a = ((R1 + R2) / 2) Where “a†is your semi major axis, and R1 and R2 are your Apoapsis and Periapsis respectively. As such, if you wanted to find the semi major access of an eccentric orbit with an Apoapsis of 200km, and a Periapsis of 100km. Then you would set up the equation like this: a = ((200 + 100) / 2) From which you would end up with: a = 150 leaving you with a semi major axis of 150. Or if for example, you had a circular orbit with both an Apoapsis and a Periapsis of 100km. Then your semi major axis would (unsurprisingly) be 100km. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Thank you for reading, and as stated above; please feel free to criticize and otherwise give me tips on orbital mechanics as you see fit. -ODSTalex
