 Sa> of 15 active Ku-band transponders, powered by 18 40-watt
 Sa> travelling-wave tube amplifiers (TWTAs).  The spacecraft
 Sa> will use gallium arsenide solar cells to generate more than
 Sa> 1400 watts of spacecraft power at end of life and will rely
 Sa> on nickel-hydrogen batteries for power through eclipses.
 Sa> Thor II is designed to operate for more than 11 years and
 Sa> will be located at 0.8 degrees West longitude.
What will the mass of this satellite be when it reaches its 
final orbit?  What is the mass of the most massive satellite ever 
put into a geostationary orbit?  What launch vehicle was used to 
put it into orbit? 
 Sa> EchoStar had approximately 480,000 DISH Network subscribers
 Sa> as of March 31, 1997.
How many subscribers does it need to break even?  What is the
