I'm sorry, but I've searched through the manual, but cannot figure out for the life of me how to re-dock with my station in order to carry out repairs, buy weapons, etc.. Could someone point me in the right direction, please?

I'm terribly sorry for my obvious stupidity.. :'(

Okay, on the radar there are several shiny objects. Head towards the one marked S, it should lead you to a rectangular object with one side open, fly in and hit return/enter.

What he said, and the boxes with the blue force-field are exits. Look for the ones without the forcef-field that are marked with flood lights.

As long as you're not being blinded by the floodlights as you make your way in for a ten-point landing, you should do fine. ;)
