Cluster and Double Star witness a new facet of Earth’s magnetic behaviour   Artist's impression of the neutral sheet oscillations observed in Earth's magnetotail by the four ESA/NASA Cluster spacecraft (in blue) and the CNSA/ESA Double Star TC-1 spacecraft in red. The five spacecraft were engulfed by waves of electrical and magnetic energy as they travelled through Earth’s night-time shadow on 5 August 2004.
The data collected by the spacecraft are giving scientists an important clue to the effects of 'space weather' on Earth’s magnetic field.  An artist's impression of the Cluster quartet.  The Double Star TC-2 spacecraft during the Sun simulation test. Release date: 30 August 2010 |
