Below is the rev 1 Earth-Fixed Greenwich (EFG), State Vector for STS-65.  
This vector comes from NASA Goddard Space Flight Center (GSFC) and is 
provided courtesy of the DOD C-Band Radar Network.
 
The data between the dotted lines may be read directly by VEC2TLE to 
estimate 
the Keplerian Elements for STS-64 in NASA Two-Line (TLE) format.  The 
VEC2TLE 
software is available from a variety of sources including AMSAT-NA, the NASA
Spacelink BBS (205) 895-0028 and at the following Internet FTP address:
oak.oakland.edu:/pub/msdos/hamradio/v2l9331.zip -- VEC2TLE may be 
registered 
free of charge for hobby use.

The drag values are estimated by VEC2TLE using a 1.0 drag multipier.
 
To create a file for use by VEC2TLE, simply write the data between the 
dotted lines to a new (text) file.  I recommend that the file you save
have a .VIF extension (default for VEC2TLE vector input files).  
 
MSDOS/PC software is available for conversion of
OSV to 2 Line Keplerian Elements via ftp to:
oak.oakland.edu:/pub/msdos/hamradio/v2l9331.zip
and the SIMTEL archives.
