The acceleration environment of any orbiting spacecraft such as the International Space Station (ISS) is not truly “zero G” as sometimes assumed. This popular idiom applies only to the vehicle’s center of mass, a point that is not necessarily a physical part of the spacecraft’s structure. All the rest of the mass that comprise the vehicle or are otherwise attached to it will experience accelerations from a variety of sources, such as pumps, fans, thrusters, atmospheric drag, rotational forces and others. These accelerations are often referred to as disturbances in that they can introduce undesired effects. These disturbances are mostly transmitted mechanically through the vehicle structure or acoustically through the air within the habitable modules.
