All,

The 2 supports were nominal for CMD and TLM. The Inertial maneuver was successful. The Spacecraft had a Soft BCR reset on 25 March 19 @07:20:00z. We recovered the spacecraft on the USAK01 support with standing CAR #997 “BCR Software Reset Recovery”. The battery controller is back to Voltage. The Tank heater set points have been set back to 16 on and 18 off. The CEU 5V and the PCM B switch shows on. The gyro is not inhibited and not the nutation sensor.

We executed CAR #1009 ISN season and HI background test sweep table uploads Pass# 6 “Upload Hi normal sweep table”. The final pass will be on May 5, 2019.
