Revision as of 16:07, 30 October 2014
In KSP, one of the hardest things to doing without leaving Kerbin's SOI is a docking procedure. It can be a very complicated procedure but once you understand it, you'll learn it's not as hard as it seems. Just, remember to quicksave often. (f5 to save and f9 to load last quicksave)

Конструирование ракеты
A very important part of everything in KSP is of course the rocket, if you are at this page and don't know how to build a rocket capable of doing this, you should probably watch some videos, read some tutorials, and re-visit this page in a few weeks. But there are some things that are necessary for docking which should always have on your rocket:
- docking ports, A docking without a docking port is usually pretty hard to accomplish. A docking port is required on ALL ships to be attached. I usually use 2 around the center perfectly opposite each other to balance themselves out but it is also common to put multiple ports for the attachment of multiple pieces and/or shuttlecraft (The coolest thing you can have on a space station). This is only useful for complex stations though so don't worry about that now.
- solar panels, don't wanna run out of power and explode? well you'll need solar panels. Alot of power is not usually required so if you just want to not die you can use OX-Stat Photovoltaic Panels or small unfolding ones, However, if you want your station to look super cool, use the gigantors! they're awesome (but heavy) ***Note! if you put gigantors just above a docking port and unfold it then they will hit any ship docked there! it is important not to put solar panels on the same side as the docking ports!
- lights, if you have alot of power then lights can really help you out, you have a 50/50 chance of docking without any sunlight whatsoever so if you can afford it,lights may be a good investment.
- RCS, A reaction control system is required for docking, to move your ship in place and to get it to the other port, Remember to conserve, docking can take alot of monopropellant so if you're using an RCS to stabilize your ship keep track of your reserves One time I was ready to dock and I realized I had no RCS system, don't be like me.
