All,

 

The pass was mostly nominal for CMD and TLM. The Inertial maneuver was successful. There were a few minutes of TLM/CMD outage between 14:07z and 14:11z on August 3 at USAK01. This was caused by a loss of communication between SSC and the station. MOC was already finished with the SSR dump at this time so there were no impacts to the downlink. SSC will issue a PR due to the loss of communication.

 

The following was completed:

August 2

Reset Master Timer

CAR #1052 Orbit #457 ATS, Uplinked 93 commands

 

August 3

SSR Dump New and Reset Pointer
