1. THEMIS Mission and Substorm Simulation: This data visualization illustrates how the five THEMIS satellites in their final nightside orbits work together to detect substorm events in the magnetosphere. The magnetosphere data is a simulation from the Geospace General Circulation Model (GGCM). > For high resolution media Credit: NASA/SVS

3. March 23rd Substorm from Polar: Important discoveries from THEMIS began during a March 23rd substorm. This movie from the Polar satellite shows the auroral outbursts of that substorm.

7. Flux Transfer Event

8. Flux Ropes or Boundary Waves?: THEMIS encountered its first magnetic rope on May 20. Flux ropes bulge outward in both directions, while Boundary waves bulge one way or the other.

9. Observation and Interpretation: Five THEMIS spacecraft were used to construct cross-sections indicating a flux rope detached from the magnetosphere. > Larger version

10. Flux Ropes Power the Magnetosphere!: THEMIS discovered a flux rope pumping a 650,000 Amp current into the Arctic.
