MMS Stacked!

All four MMS spacecraft are stacked and ready for transport to the vibration chamber for environmental tests. Although they will be disassembled again later this month, this image is a sneak preview of what will be the final flight configuration of the MMS fleet.

The Magnetospheric Multiscale (MMS) mission is a Solar Terrestrial Probes mission comprising four identically instrumented spacecraft that will use Earth’s magnetosphere as a laboratory to study the microphysics of three fundamental plasma processes: magnetic reconnection, energetic particle acceleration, and turbulence. These processes occur in all astrophysical plasma systems but can be studied in situ only in our solar system and most efficiently only in Earth’s magnetosphere, where they control the dynamics of the geospace environment and play an important role in the processes known as “space weather.”

Mission Status

Agency Baseline Commitment: March 2015
Launch Readiness Date (LRD): March 2015
Phase C/D: Design & Development
Mission Highlights – As of 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. The Space Network (SN) and MOC teams successfully completed the SN newly installed automated ground scheduling software. The MOC also successfully completed the Backup MOC telemetry and command interface and data flow test with WSC Programmable Telemetry Processors (PTPs).
