This antenna is operated remotely from JHU or by staging automated control of ground station passes when the control center is unstaffed.

The pipe sticking out of one side of the spacecraft represents one of two radio antennas used by the satellite to talk to the ground. The white rectangles in the picture show positions of radiators on {\it FUSE} that remove excess heat from the onboard electronics.

Rather, its pointing and stability are controlled by devices in the spacecraft section of the satellite that are computer-controlled. Spinning wheels called Reaction Wheel Assemblies (RWAs) create torques (forces) that control the pointing, and gyroscopes inside two Inertial Reference Units (IRUs) sense the changes in position and feed this information to the control computer. In late 2001, problems developed with two of the RWAs, and the control system was updated to use other devices (called Magnetic Torquer Bars [MTBs], essentially electromagnets) to assist in controlling the pointing. By running electric current through the MTBs, magnetic fields are generated locally that interact with the Earth's magnetic field to help stabilize the satellite pointing. {\it FUSE} can be pointed to better than 1 arcsecond (1/3600th of a degree) using this revised control system. } %=============================================================================== % Figure 7 %=============================================================================== {{\vspace*{0.25 in} \epsscale{0.95} \begin{center} \plotone{Spacecraft_fig.eps} \end{center} } \parbox{\cwd in}{\cappar \ \ \\ \bf Figure 7.~~The inside of the {\it FUSE} spacecraft is mostly empty space!
