Fregat RB/Cluster 2



Fregat RB/Cluster 2 was a Russian experimental upper stage rocket body (Fregat), and a dummy payload (Cluster 2) to simulate the soon (June/July 2000) to be launched ESA's Cluster mission. Fregat was a reusable rocket described in the launch text of Fregat (2000-009A). The separation of the rocket body and the dummy was not planned, but the separation was simulated successfully. The couplet was launched by a Soyuz-U rocket from Baikonur at 18:28 UT. It is likely that after these and more successful launches of the Fregat rocket, future commercial or scientific launches of the Soyuz-Fregat combine will take place from French Guiana.
