Hub-and-spoke conspiracy in the conspiracy. My colleagues believe, and I believe, that there was no such evidence in this record. In short, there was no rim to this wheel, or to put it in more conventional antitrust language, there was no proof of a horizontal conspiracy. However, he considered it proper to find a single conspiracy as in "Poliafico". He found "Kotteakos" inapplicable because that was a ruling to protect the spokes from being tarred with one another's conduct after the hub had pleaded guilty. Here, in contrast, the supplier spokes are not in court, "and the case proceeds against the central
Reaction wheel temporary changes in its speed result in small changes in angle. The wheels therefore permit very precise changes in a spacecraft's attitude. For this reason, reaction wheels are often used to aim spacecraft carrying cameras or telescopes. Over time, reaction wheels may build up enough stored momentum to exceed the maximum speed of the wheel, called saturation, which will need to be cancelled. Designers therefore supplement reaction wheel systems with other attitude control mechanisms. In the presence of a magnetic field (as in low Earth orbit), a spacecraft can employ magnetorquers (better known as torque rods) to transfer angular momentum
