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 July 24, 2014:

  • The Thermal-Vacuum (TVAC) test of Observatory #3 at NRL is ongoing with no Observatory issues.
  • The Navigator has been reintegrated to Observatory #1.
  • Dual Ion Spectrometer (DIS) FM12 completed testing at MSFC and delivered to GSFC last week, ahead of schedule, and has been integrated and tested on Observatory #2. FM11 is in test at MSFC, the last outstanding Fast Plasma Investigation (FPI) instrument, and will be delivered to Observatory integration the second week of August at the latest.
  • Mission Readiness Test 9c (MRT-9c/Orbit-in-the-Life) was executed successfully on Observatory #3 during the TVAC test last Friday.
