Cluster Spacecraft Give Each Other Some Room
(Jul 14, 2005) The European Space Agency's fleet of 4 Cluster spacecraft put a little more distance between each other, during a difficult repositioning maneuver completed this week.
Three of the spacecraft were separated to 10,000 km from each other, with the fourth moving 1,000 km away from the third. By shifting the distance of the spacecraft, from 100 km to 5,000 km, and now 10,000 km, scientists are able to study the Earth's magnetic field at different scales. This maneuver also marks the fleet's fifth year of operation.
