This CAP disables power to Thermal Primary Operational Bus 6 to turn off the Zone 50 stuck-on heater. This CAP will shut off power to HRMA Primary Operational Zone 29, and OBA Primary Operational Zones 35, 42, 44, 46, 48, 50, and Aft Bulkhead Primary Operational Zone 54. The CAP will also disable commanding to Thermal Primary Operational Bus 5, HRMA Primary Operational Zones 27 & 28, and OBA Primary Operational Zones 43, 45, 47, 49, 52, and Aft Bulkhead Primary Operational Zone 53. The intent of this CAP is to disable Primary Operational Bus 6 (and Bus 5 commanding) for the rest of the mission, and provide a decrease in ACA temperatures. Radiation: Solar activity is expected to be very low with a slight chance for a C-class flare on days one, two, and three (14 Apr, 15 Apr, 16 Apr). MP: Apr1921 loads review today. ENG: No issues. GOT: No issues.
