The Cluster Flight Model 5 satellite was refurbished after the Ariane 5 failure to become Project Phoenix. It was renamed Rumba. It was launched with Cluster FM8 on a Soyuz in Jul 2000. into a 250 x 250 km x 51.8 deg orbit. A Fregat kick stage raises the orbit to 250 x 18000 km x ?. Then the satellites separate from the kick stage and use their S400 engines to get to the 4 x 19.6 Re orbit. 25500 x 125000 km polar.

Mass of Cluster/Fregat at Blok I sep is 7847 kg. After MECO-1 mass is 6810 kg.

The Blok I suffered an 3.5s underburn,possibly due to the stage having too little fuel loaded. The Fregat made up the difference. A report said that the second Fregat burn went till depletion, but other indications are that the Fregat did make a third deorbit burn since Space Command tracked it with a negative perigee after apogee.

Cluster FM5 was known after launch as Rumba and as C1.
