All,

    The spacecraft went thru a BCR Soft reset on 10 Dec 2021 @17:05:00. The spacecraft state @ AOS was the following:

PCMB =off and CEU Safe = off – these 2 tlm points were actually on but because of the reset the software logic had them showing off.

TANK 1 & 2 heater set points were at 12 on and 14 off

GYRO showed inhibited

Star tracker was on and at 78 percent valid

Power control was in relative

During the contact the following was completed:

Power control was commanded to voltage

Tank Heater Set points were commanded to 16 on and 18 off

CEU Safe flag was commanded to the on state

PCM B was commanded to the on state

The GYRO still needs to be turned on and that will be completed on the upcoming contact @ 14:00.
