A slow fly-around of the MMS tetrahedral formation to better view the 3-dimensional structure of the data.

In this data visualization, we fly around with the MMS spacecraft in tetrahedral formation. The mesh structure in the distance is the magnetopause.

Each image frame corresponds to a time step of 30 milliseconds, one of the faster data sampling modes for MMS.

The arrows represent the data collected by the spacecraft. To better comprehend changes as the spacecraft moves along, the data are allowed to 'echo' along the spacecraft trail. The length of the vectors represent the relative magnitude of the vector. However, the electron and proton vectors are scaled so equal velocities correspond to vectors of equal magnitude.


  • Magenta represents the direction and magnitude of the magnetic field at the spacecraft position.
  • Yellow represents the direction and magnitude of the bulk motion (total average) velocity of the electrons measured at the spacecraft position.
  • Blue represents the direction and magnitude of the bulk motion (total average) velocity of the protons measured at the spacecraft position.
