    Summary: Update the missile indicators, set up the planet data block
    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * SOLAR calls SOS1
             * TT110 calls SOS1


 Update the missile indicators, and set up a data block for the planet, but
 only setting the pitch and roll counters to 127 (no damping).
