THEMIS Orbits: Nightside Science Configuration
In the latter phase of the mission, the five THEMIS spacecraft will travel on five co-aligned elliptical orbits with their apogee on the nightside of the Earth. From there, they will sample the particle and electromagnetic wave environment along the magnetotail.

The dates in this visualization are based on an ephemeris assuming a launch date of January 20, 2007.

The five satellites are represented by colors: red=P1, green=P2, cyan=P3, blue=P4, magenta=P5


This movie starts from a view of the aurora (simulated) over the north polar region and pulls outward to show the THEMIS spacecraft sampling the region of space 'downwind' from the Earth.    This movie starts from a view of the aurora (simulated) over the north polar region and pulls outward to show the THEMIS spacecraft sampling the region of space 'downwind' from the Earth.
