THEMIS Dayside Science - Sampling the Bow Shock
In the early part of the mission, the five THEMIS satellites follow the same orbit single-file. The apogee of the orbit takes the spacecraft just beyond the bow shock of Earth's magnetosphere. This enables the closely spaced satellites to measure the thickness of the different regions that they encounter.

The movie zooms up to the Earth from the direction of the magnetotail to view the orbits of the THEMIS satellites in their dayside orbital configuration.    The movie zooms up to the Earth from the direction of the magnetotail to view the orbits of the THEMIS satellites in their dayside orbital configuration.

How to play our movies


We start out looking along the line of Earth's magnetotail for a view of the Sun, the Earth, and the orbit of the Moon.    We start out looking along the line of Earth's magnetotail for a view of the Sun, the Earth, and the orbit of the Moon.

Now we get a view of the Earth and the orbits of the five THEMIS spacecraft. The yellow arrow reminds us of the direction to the Sun (which determines the direction of the magnetosphere).    Now we get a view of the Earth and the orbits of the five THEMIS spacecraft.

We move in a little closer to better observe the satellites as their orbits carry them in and out of the magnetosphere. This enables them to sample particles and fields in the solar wind outside the magnetsphere and their effects on the magnetosphere as well.    We move in a little closer to better observe the satellites as their orbits carry them in and out of the magnetosphere.
