All,

    Today’s apogee contact was not successful for real time CMD and TLM.  We were unable to connect to SSC NMC. Razor # I100 675 – “USHI01 failed to connect 10/17/20 @22:30” has been opened and is still under investigation. I did have SSC bring up there command carrier and track the spacecraft. So, we should still be able to get tracking data from the pass. I did receive the VCID0 data post pass and was able to verify that the maneuver was successful and the spacecraft is healthy. We will continue to troubleshoot this incident and to restore connectivity between the MOC and SSC NMC.
