Fregat's successful qualification flight puts Cluster II in fine fettle
Preliminary analysis of Monday's Cluster II Mission Validation Flight showsthat the Fregat upper stage on the Russian Soyuz rocket has passed itssecond test with flying colours.The objectives of this flight were to confirm the re-ignition and orbitalmanoeuvring capabilities of the Fregat, and to validate the mission profileto be used by ESA's Cluster II scientific satellites. The newly developedFregat ('frigate' in English) is now ready to launch the Cluster II quartetthis summer.

Long-distance fuel delivery gives Cluster II Spacecraft A Boost
A lot of down-to-Earth preparations have to take place before the ambitious Cluster II mission to study the magnetosphere can be launched into space this summer. One of the most difficult stages was completed at the weekend when a high security cargo of explosive fuel arrived under armed guard at the Baikonur Cosmodrome in Kazakhstan.

And then there were four
On 9 March, after a successful stack test with its sister spacecraft (FM 8), the fourth and final Cluster II satellite (FM 5) completed its rigorous series of environmental tests. With the successful culmination of their assembly, integration and verification programme, the Cluster II quartet are now ready for transportation to Baikonur Cosmodrome, the next major landmark on the road towards launch this summer.

Dublin Concert is out of this world
An interest in space exploration is frequently considered to be the preserve of scientists, but, as a concert last night demonstrated, this is not necessarily the case. A packed audience at St Patricks College, Maynooth, near Dublin, enjoyed a unique aesthetic experience in which space science and music were intertwined.

The Phoenix prepares for flight
Three and a half years ago, after the tragic loss of four Clustersatellites in the Ariane 501 launch failure, European scientists andengineers came together in an effort to salvage something from thewreckage. Their proposal was to assemble a fifth Cluster from spare partsleft over from the ill-fated mission.

INFO 16-1999: Cluster II quartet take the stage together
Visitors to the test and integration facilities at IABG near Munich, Germany, on 24 November may be excused for thinking they are suffering from multiple vision. On display there, in a giant clean room, will be not one but four identical cylindrical spacecraft. This is the only occasion on which all four of ESA's Cluster II spacecraft will be on display together in Europe.

Boom Time for Cluster II Spacecraft.
We are all familiar with normal gravity which holds us to the ground andpulls us backto Earth when we try to jump or fly. However, as images of space missionsshow,people and objects become 'weightless' once they enter orbit. Over theyears,spacecraft engineers have been obliged to develop various ways of copyingsuchunusual conditions.

First Cluster spacecraft is the ultimate 'Clean Machine'
What happens to a spacecraft when it has been assembled and tested, and its launch date is still almost a year away? For Cluster II engineers and technicians, pushing the spacecraft into a dusty cupboard and forgetting about it is not an option.The satellite has to be continually monitored and looked after with tender, loving care.

Cluster II scientists review new data system
Well over 200 scientists around the world are looking forward to receivingthe vast flow of data that will start streaming back next year from ESA'sfour Cluster II spacecraft. Apart from the ESA member states, they includeCo-Investigators from the United States, Russia, Czech Republic, Hungary,India, Israel and Japan.Since 44 instruments on the four Cluster II spacecraft will return about330 Gigabytes (330,000,000,000 bytes) of data over two years - equivalentto 165 million pages of printed text - the efficient worldwide distributionof this vast amount of information is of major concern to the sciencecommunity.
