Well, today at work I got to thinking about that statement that co op made the other day(see below). I was in the middle of writing down how to log in to my console at MCC(top left corner). I then wondered about the "weight" difference in space and how much less force would be needed to accelerate a 2000 kg mass at .01 m/s^2. Well, I worked out the problem, and the answer is at the bottom. I then began to wonder about the difference in atmospheric drag the ISS experienced at different times in orbit, and that is diagrammed at the top right. Just shows you how my mind works sometimes, from one thing to the other.
