[/quote] Correct me if I'm wrong though, but I believe that weight matters very little in space? Again I'm not sure about this, just something I read about once.[/quote] The force required to move an object in space is equal to that required to move it on Earth. While you're technically correct in stating that weight matters little in space, mass still matters, and mass times gravitational pull is how we determine weight. The greater somethings mass is, the harder it is to change its velocity. This applies planetside and in space. The difference is that here you have gravitational pull and friction working for or against you. In space there is very little of that. So yes, the "weight" of a vessel affects its ability to maneuver. [Edited on 01.22.2010 5:38 AM PST]
