Thanks Tim, that’s good news.

So the SSR dump looked ok?

I’d like NG to look closely at the events that led to the spacecraft entering Contingency State and make sure we understand why the instruments were powered off but the star tracker and CEU stayed on.

Greg Dunn and John Hanley, do you have access to the data you need to look at the CEU functionality through the anomaly?

Thanks,

Nigel

All,

   The perigee passes were nominal for CMD and TLM. The Inertial maneuver was successful. As part of the string-2 recertification, I took the second pass on in it. CMD and TLM was nominal.  

The following was completed:

Reset the Master Timer

Set the Spacecraft Clock

Reset FDC totals

SSR Dump -> Dump_New
