   The configuration of the Ulysses spacecraft is dominated by the large-     
   diameter (1.65 m), Earth-pointing High-Gain Antenna (HGA) providing the    
   communication link and by the Radioisotope Thermonuclear Generator         
   RTG) supplying the spacecraft's electrical power (this is a single         
   radio-isotope RTG with a 285 W power output at the beginning of the        
   mission). The spacecraft is spin-stabilized and rotates at 5 rpm during    
   its operation.  When the HGA is deployed Ulysses is able to transmit data  
   to Earth at rates upward of 4 kbit/s.                                      
                                                                              
   Propulsion for orbital injection is provided initially by a US Air         
   Force Inertial Upper Stage (IUS) and augmented by a PAM-S boost motor.     
   Rotational and velocity adjustments are done using a series of 8 catalytic 
   decomposition thrusters (2 Newton) arranged on two manifolds, being fed by 
   mono-propellant hydrazine under pressure. At launch time the spacecraft's  
   weight was 367 kg with 55 kg for the scientific payload and 33.5 kg of     
   hydrazine.                                                                 
                                                                              
   Experiment requirements for electromagnetic cleanliness and for            
   minimization of the RTG radiation environment resulted in a 5.6 m long     
   radial boom which carries several experiment sensors and is mounted on     
   the opposite side of the spacecraft to the RTG.  A 72.5 m wire boom,       
   consisting of two 35 m wire antennas to create a radial dipole antenna,    
   and a 7.5m-long axial boom, acting as a monopole receiving antenna, serve  
   as the electrical antennas for the Radio and Plasma Wave Experiment. Most  
   of the scientific instruments are mounted on the main body, as far as      
   possible removed from the RTG, and in compliance with the field-of-view    
   requirements of the experiment sensors.
