Mission details:

The second test launch of the Soyuz-Fregat launch vehicle succeeded on Mar 20. The Fregat upper stage placed a dummy satellite, Dumsat 2, into orbit. Dumsat, built by Aerospatiale Matra, is a mass model of a pair of Cluster 2 scientific satellites. Dumsat remained attached to the Fregat stage, in a 244 x 18016 km x 64.6 deg orbit. The Soyuz third stage flew a suborbital trajectory.
