Hi all. I'm new on the forums and i have trouble understanding some of the abbreviations you guys use. That is, if i can actually be troubled to read the posts and not look at the pictures and picking my jaw up from the ground Seeing the stuff some of you guys get into space... wow... Anyway... KSP is simple enough LKO, Lower Kerbal Orbit? I'm guessing here. But what is an SSTO? Or what does FAR, KIDS, TWR mean. And there are loads of other abbreviations that make my head spin :') My humble apologies for my ignorance. I googled and searched the forums, but couldn't find a complete list :X
