I've updated Zorkinian's OrbitalConstruction mod for KSP 0.21. I've modified the orbit setting mechanism to work like HyperEdit, so it should no longer blow up your ships. It also now includes a landing feature. License: Everything I make for KSP, I place into the public domain. The same cannot, unfortunately, be proved for Zorkinian, who originally made Orbital Construction. They never told me *not* to maintain their mod, so I did it. Version 4.2 of this mod has compatibility with the latest Extraplanetary Launchpads and the Kethane 0.7.7. Unfortunately, due to inflation, RocketParts from previous saves are now worth only 1/400 as much. The basic premise of this mod is that you build SpaceDocks (ships tagged with a certain part) in orbit around whatever you want. You then launch containers of RocketParts out to your SpaceDocks to fill them up. When that is done, you can build your ships at any SpaceDock, at the cost of RocketParts. Download: Version 4.2 from MEGA.co.nz Mirrors: Version 4.2 from FileSmelt BUGS GO HERE. I rarely check the KSP forums, but Github bugs go straight to my inbox. The download has all of the OrbitalConstruction parts except the JumpDrive (which will not work with my version of the plugin) and a mis-categorized and overpowered Warehouse (which I have removed). It also now includes the "KE-OC-3D-OMG 3D Printer", which makes Rocket Parts out of Kethane at 99% mass efficiency. Right now this shows up as the Kethane pack's big Kethane converter, loading the model from the game's database; it will probably not show up at all correctly if Kethane isn't installed. I'm accepting submissions of better models for this. Fork me on GitHub! How To Use: All parts are found under "Control". 1. Build a ship that has the SpaceDock part, and a container that holds RocketParts (the "Orbital Warehouse" parts are recommended). Put it into orbit, or land it somewhere. 2. Ship cargo containers of RocketParts to your space dock, until you have enough RocketParts there. RocketParts are just like any other resource; you can transfer them between ships while docked. To build a ship in orbit, you will need 125% of its mass in spare parts. 2.1. Alternately, you can ship Kethane to your SpaceDock, and convert it into RocketParts with the "KE-OC-3D-OMG 3D Printer". 3. Make a ship with one SpaceBuilt part on it, and launch it from the launchpad. (Using ships with "Launch Stability Enhancers" on them is now supported!) Use the "Orbital Construction" window to "Scan for docks". Select the SpaceDock you launched earlier, and hit "Build at selected dock". Your ship will be teleported into the same orbit as the selected dock, around a kilometer or so away, and the required amount of RocketParts will be deducted from the SpaceDock's supplies. If the dock was on the ground, be sure to click "Land at dock" to have your ship gently lowered to the ground in the vicinity of the landed SpaceDock. While it's slowly descending, make sure to rotate it so that it lands upright. Once it lands, the magical hover-field will dissipate. Don't be alarmed when there's an explosion after the last button click; that's the SpaceBuilt part self-destructing.
