    By the launch time they will be near the  sunrise/sunset line. The orbit is sunsynchrinous,
    the jigher inclination to bring the rate of change of RA of node to the required
    .9856 degrees/day
    
    One comment about the web page is that the existence of a current constellation 
    the ESA -Cluster/China-Double star constellation is completely ignored, in the
    science section. This constellation have orbital changing thrusters and attitude control.
    The educational part of this project is misleading students if it totally ignores the
    existence of Cluster.
