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.
