The command to turn off the heater was executed in the load at: 2007:297:12:57:14.437 COMMAND_HW 1HHTRBOF and the heater will be turned on again at: 2007:298:20:07:39.016 COMMAND_HW 1HHTRBON for a total of about 113 ks of cooling time. SUMMARY: ------- Comm came up on schedule. The telemetry seen was: 1DAHTBEN=EN 1DAHTBON=OFF 1DAHHBVO= 28.80 (value of the mean over 10 samples) 1DAHBVO= 0.0 (value of the mean over 10 samples) 1DAHBCU= 0.0 (value of the mean over 10 samples) 1CBBT= -67.29 (value of the mean over 10 samples) 1CBAT= -69.25 (value of the mean over 10 samples) 1WRBT= -84.45 (value of the mean over 10 samples) 1WRAT= -84.45 (value of the mean over 10 samples) The last data was received at 2007:298:14:29:43. Side A camera body temperature had dropped one more tick. The telemetry seen was: 1DAHTBEN=EN 1DAHTBON=OFF 1DAHHBVO= 28.80 (value of the mean over 10 samples) 1DAHBVO= 0.0 (value of the mean over 10 samples) 1DAHBCU= 0.0 (value of the mean over 10 samples) 1CBBT= -67.29 (value of the mean over 10 samples) 1CBAT= -69.75 (value of the mean over 10 samples) 1WRBT= -84.45 (value of the mean over 10 samples) 1WRAT= -84.45 (value of the mean over 10 samples) There is a comm pass scheduled in the load for 2007:298:18:10, during which the commands will be issued to enable the ACIS detector housing heater and power it back on.
