Below is the current State Vector and Keplerian Elements for STS-81.  
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 telnet: oig1.gsfc.nasa.gov (UserID = oig / 
Password = goddard1).  
 
This file may be read by VEC2TLE version 9648 to update your 
Keplerian Elements text file.
