# PROGRAM DESCRIPTION- MISSION PHASE 3 - SUBORBITAL ABORT DATE- 28 OCT 66
# MOD NO- 0 LOG SECTION- MP 3 - SUBORBITAL ABORT
# MOD BY- GILBERT ASSEMBLY- SUNBURST REVISION 17
# FUNCTIONAL DESCRIPTION
# IN THE FIRST 10 SECONDS OF THIS PHASE, THE GROUND IS CAUSING THE NOSECONE TO BE JETTISONED AND THE SLA
# PANELS TO BE DEPLOYED. 10 SECONDS AFTER RECEIPT OF THE ABORT COMMAND, MP3 CHECKS TUMBLING AND PROCEEDS ONLY
# WHEN THE INDICATED TUMBLING RATES ARE LESS THAN 3 DEGREES PER SECOND. MP3 THEN STARTS +X TRANSLATION AND
# COMMANDS SIVB/LEM SEPARATION. 13 SECONDS AFTER SEPARATION THE DESCENT ENGINE IS TURNED ON FOR 5 SECONDS, THEN
# IGNITED AGAIN AFTER A 5 SECOND COAST AND LEFT ON THROUGH THE ABORT STAGE COMMAND WHICH IS SENT/RECEIVED 31
# SECONDS LATER. THE APS ENGINE IS TURNED OFF 5 SECONDS AFTER ABORT STAGE, THEN IGNITED AGAIN AFTER A 30 SECOND
# COAST FOR A FINAL 60 SECOND BURN. IMU COMPENSATION CONTINUES THROUGHOUT THIS MISSION PHASE.
# CALLING SEQUENCE
# SUBORBITAL ABORT IS STARTED AT THE DISCRETION OF THE GROUND IN THE EVENT OF AN ABORT DURING THE EARLIER PART
# OF BOOST. KEY CODE 23 IS SENT VIA UPLINK.
# SUBROUTINES CALLED
