description Cluster Overview

Cluster is a space mission developed by the European Space Agency (ESA) to study the Earth's magnetosphere and its interaction with the solar wind. Launched in the summer of 2000, the mission consists of four identical spacecraft flying in a tetrahedral formation. By maintaining this specific geometric configuration, scientists can map the spatial and temporal variations of magnetic fields and plasma in three dimensions. The mission continues to provide critical data regarding space weather and phenomena like auroras.

help Cluster FAQ

What was the primary goal of the ESA's Cluster space mission?

The Cluster mission was developed by the European Space Agency (ESA) to study the Earth's magnetosphere and its physical interaction with the solar wind. It was specifically designed to provide unprecedented 3D mapping of these magnetic phenomena.

How many spacecraft were part of the Cluster mission?

The mission consists of four identical spacecraft flying in a precise tetrahedral formation. This unique configuration allows scientists to distinguish between spatial and temporal variations in near-Earth space weather.

When were the Cluster spacecraft successfully launched?

The current Cluster spacecraft were successfully launched in the summer of 2000. This launch successfully deployed the four satellites into their highly elliptical Earth orbits.

Where do the Cluster satellites orbit the Earth?

The four spacecraft orbit the Earth in highly elliptical polar orbits. This specific path allows them to pass directly through the Earth's magnetosphere, giving them continuous access to study solar wind interactions.
