     One reason the Shuttle can't retrieve the commnications satellites
is there is no place to put them in the cargo bay.  Originally, the
satellites were attached to the Star-48 Solid Rocket Motor (a Morton-
Thiokol product).  The motor in turn was attached to the PAM-D spin
table.  The spin table is what gave the satellites their spin in the
cargo bay before deployment.  It consists of a large bearing and a motor.
Now that the solid motor has separated from the satellite, there
aren't the right bolts to tie down the spacecraft.

     Think about it, do you want a 1200 pound satellite rattling around
the cargo bay while performing 1.5 gee reentry, 75 degree banks, etc.?
You want it bolted down good.
