Cluster's whispers probe the electrifying plasmasphere
An astronaut who exits a spacecraft without a spacesuit will die very quickly because there is no air to breathe. However, although space is often regarded as an airless vacuum, it is by no means empty. Spacecraft such as Cluster are built to detect and study the sparse 'soup' of electrified plasma - mostly electrons and protons - that populates near-Earth space.

The 'ins and outs' of Cluster's celestial dance
Some 100 scientists and engineers gathered last week at the European Space Technology Research Centre (ESTEC) in the Netherlands for the 36th ClusterScience Working Team (SWT) meeting. They were greeted with the news that the four Cluster spacecraft - Rumba, Salsa, Samba and Tango - are now dancing in a new formation around the Earth.

Cluster quartet move in step
Moving time has arrived for the four Cluster spacecraft. During the next few weeks, the satellites will carry out a series of manoeuvres that will increase their separation distances. Eventually, each spacecraft will havedrifted to a distance of 2000 km from its partners, compared to the current figure of 600 km.

Unique science results from Cluster's Lunar eclipse
In the summer of 1999, millions of people across Europe peered upwards at the sky in an effort to see one of Nature's wonders - a total eclipse of the Sun. On 25 January, European engineers and scientists witnessed an eclipse of a different kind - the passage of four Cluster spacecraft through the outer part of the Moon's shadow.
