All,

   Tonight’s support was nominal for CMD and TLM. The Sun Maneuver was successful.

The following was completed:

The Haw02 contacts for July 23 and 26 were unsuccessful for CMD and TLM due to a T1 outage. We were able to collect the TLM data and range data from these 2 supports. The TLM files have been copied to the server and archived. The T1 was restored on 26 July ~06:00 pm Eastern. The Inertial maneuver was verified post pass.
