Below is the current State Vector and Keplerian Elements for ORFEUS/
SPAS. The vector data comes from NASA; the orbital parameters were 
computed from the vector.  Hourly vector updates are available from 
NASA GSFC OIG RAID RBBS at (301) 262-6782 or by telnet: 
oig1.gsfc.nasa.gov (UserID = oig / Password = goddard1).
