I'm sort of a newbie to the list.  I have been subscribed to it for nearly a year, 
yet I have never posted.  I have a question about the satellite situation report 
that is very kindly posted by Mr.McCants:


> Internatl.                   Catalog Object Launch Period Incli- Apogee Perigee

Correct me if I wrong, but in the international dsignation, the first four numbers 
are the year, and the other three are the days in the year? If so, I guess thse 
object were luanched in 1968 and 1993 respectively and are both dead stages 
from spent rockets(by the way, what is Start 1?).  Now since this is under the 
category of newly added objects, does that mean these objects have been 
floating around in LEO for all this time without being tracked?

Looking at this list, I see that some ojects have been flying around uselessly 
for many years.  Are they international agreements to keep this trash to a 
minimum?  I know its pretty neat to see  a tumbling booter from the back porch 
of my place, or while I am out backpacking, but as the larger constellations of 
sats get launched, there is gong to be an incrediable amount of trash up there.  
I'm sure I'm not the only person who has noticed this for some years now, but I 
had no idea that the COBE DEB, lauched back in 1989 is still floating around 
up there.  Also, what does the letters at the end of each international 
designation mean? 


thanks a heap!
