Program: Cluster 2
Following the loss of the
Cluster
satellites with
Ariane 501
a remplacement was financed. It is composed of the Phenix satellite made from
spare instruments of the first set and 3 new satellites. The satellites were
launched by pairs aboard Soyouz rockets.
The program was completed in mid-2000 for approx $265 million.
The program was extended 3 years (2005) and then another 4 years (2009).
