RUNNING

Given the low gravity of the moon, running can be very difficult. It is harder to control yourself, to make tight turns, or to stop your momentum should you find something in your way. In addition, MBA has many people living in a relatively contained space, not to mention various robots and other machinery moving about. Sudden contact with any of these things—or even the thick walls—could cause serious harm or injury. To that extent, it is advised that lunarnauts not run through MBA except in cases of extreme emergency. Not only is walking safer, but it doesn’t even take that much more time. Since MBA is rather compact in size, running from one side to the other will only save you a few seconds, at most. Are a few seconds worth hurting yourself or someone else? Of course not. So take care . . . and slow down.
