    Hi Dale and list,
    
    Starshine 3 should have been launched after Starshine 2. BUT, in December 2000,
    NASA urgently needed a new primary payload for the Kodiak Star mission that was
    to be launched at the end of August 2001. The original payload ran into
    technical and cost problems.
    
    NASA offered Starshine to be the primary payload but without changing the launch
    schedule. So we had to design and build Starshine 3 in a hurry (8 months from
    approval to completion, almost a record !) and launch a mirror polishing
    campaign immediately following the one for Starshine 2. Thanks to the efforts of
    the Naval Research Laboratory in Washington and all the Starshine partners, we
    were able to meet the deadline.
    
    The next Starshine will be no 4 and 5 to be launched at the same time from the
    payload bay of the shuttle on mission STS-114 in January 2003. They will be of
    the same size ( 48 cm dia.) but with different masses giving them a different
    ballistic coefficient. A nice experiment in orbital mechanics !
