  1. Another great video, Mate, Subscribed. Understanding the source of these signals, even if they prove not to be communications but cosmic events, will improve our knowledge of the Universe.
  2. Welcome to our 'collective' @RockKrawler. I'd love to see an IVA created by a pilot.
  3. Welcome @Moostic. I'm glad you have found your path in life and I hope you go on to make great discoveries (and also post about them in the science and spaceflight subforum ).
  4. Welcome @MrSystems. Your spreadsheet surely beats my "Slap it on in the VAB and see" technique. Can't wait to try it.
  5. As at December 2017, there are around 2400 observed trans Neptunian objects. Modeling predicts billions to trillions of these objects so, as per the GB mantra, I think we need moar data.

  6. Researchers at the University of Cambridge and the American University of Beirut have proposed an alternate theory for the orbital anomalies that do not require a massive trans-Neptunian object.
  7. Welcome to the forum, @Plebeian.
  8. Welcome to the forum, @Kerbal Madness. Cool channel you've got there, Mate.
  9. I also originally thought it was a cool but silly idea however after reading further, it is probable ALE-1 will be deployed for the 2020 Tokyo Olympic games. Image Credit: ALE Co Ltd
  10. One of the secondary payloads on this launch was from a Japanese company, ALE Co. Ltd, who intend to provide artificial meteor showers on demand.
  11. Under the RDZV tab in KER you see relative inclination and times to An/Dn in a landed vessel.
  12. Division F (Planetary Systems and Bioastronomy) of the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (hereafter IAU WG) has begun naming features on Ryugu:
  13. Welcome to the forum, @johnmorris.
  14. For a rendezvous I will usually get my inclination to 0.1° for a 'medium gravity' body like the Mun. This will help you later on and is good practice for when you begin docking. I make either Pe or Ap the same as my target and wait for the target to ensure a close encounter - in your example you will be at least 3.4km away from an intercept without adjustment. Once I'm within 50 - 80km of my target I set a maneuver node at the point I matched either the Ap or Pe and play around until I get the intersect within 1km (if you have matched planes you will only need to burn either prograde or retrograde to fine tune the encounter). With a fairly close orbit like yours the speed of the encounter should be around 20-30m/s but even if its higher, remember that a Kerbal EVA pack has about 500m/s Dv (quite a lot for orbital maneuvers). Once you are within 2.2km of your target, switch to it using the [ key and EVA your stranded Kerbal. At this point I look for the rescue vehicle and 'select as target'. From here on it's all about the nav ball so switch it into target mode if it isn't already. You should see a target or anti-target symbol in addition to the standard vector symbols. All you need to do is match up the target symbol with your prograde symbol and you are now headed towards the rescue vessel at the speed indicated on the top of the navball. You will need to make some small adjustments and then slow your Kerbal down when you get really close.
  15. Welcome to the forum @Galane. Pistachios are probably not the only nuts called Kerman.
  16. Most of us use https://kerbalx.com/. It's a really well thought out site where most of the membership shares vessels.
  17. Welcome to the forum, @Scorpion14. If you have the steam install you can try verifying the integrity of the game online: https://support.steampowered.com/kb_article.php?ref=2037-QEUH-3335
  18. Welcome to you too, @colonoscopy.
  19. Just to expand on @5thHorseman's advice - The higher altitude your Ap, the slower you are going so your vessel will linger for quite a while in relatively the same spot, behind Minmus, making an encounter easier. I like to enter the sphere of influence of minmus after Kerbin apoapsis (on the way back down to kerbin) so that I can course correct at Ap. A little trick I use when performing a course correction here is to lower my engine thrust (right click on engine, reduce bar on the thrust limiter). This is a useful method whenever you want to make fine corrections.
