The European Space Agency has delayed until February its decision on whether to fly a new Cluster science mission to replace the four $500 million Cluster satellites lost in the June 1995 Ariane 5 failure. The new mission, which would cost $325 million, would use the Cluster ground spare and three new satellites, launched separately or as pairs as piggyback payloads on Ariane 4 and 5 boosters in 1999-2000.
