- Mission Highlights - November 20, 2014
- All four MMS Observatories are now at Astrotech at CCAFS and the Functional Test of Observatory #4 is in progress this week. Launch site operations continue to proceed smoothly and on schedule. The Flight Operations Review/Operational Readiness Review (FOR/ORR) was completed this week. The Mission Operations Center (MOC) and Flight Software Sustaining Engineering (FSSE) teams successfully completed the remaining MRT-25 series to remotely load the operational flight keys to Observatories #3 and #4.

- Mission Highlights - November 13, 2014
- All four MMS Observatories are now at Astrotech and preparations for Functional Testing of Observatories #3 and #4 are ongoing. Solar Array cell inspections are also ongoing with the vendor supporting on-site at Astrotech. All operations at the launch site continue to go very smoothly.
- Mission Highlights - October 16, 2014
- The investigation into the recent Observatory #4 Side A Navigator (weak signal GPS system) anomaly has revealed a failure in a RAM-3 RF amplifier microcircuit in the same circuit location as had been previously experienced. A weakness in the design that stresses the part in this particular circuit location has now been identified that was not understood previously. A rework plan for all four Navigators is being validated by testing on the ETU and evaluation boards. All four will be removed, reworked, and reintegrated at the launch site. No impact to shipping or launch date.
