Below is the current State Vector and Keplerian Elements for STS-78.  
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).
