    This is the first photograph taken by a microsatellite of another object in
    space that has ever been released to the general public??
    
    Now wait a minute!!
    
    The earlier mission of XSS-10 micro-satellite snapped this image as it 
    closed in on second stage of Boeing Delta 2 rocket during mission 
    operations in January 2003. Image Credit: Boeing.

    According to Popular Communications Magazine, they filed a Freedom of 
    Information Act request for photographs taken by the microsatellite in 
    September, with the hope of running them in Popular Science's November 
    cover story "Battlefield Space". However, they were told that they were 
    "classified."
    
    I've used the XSS-10/Boeing photo a few times in stories I've done. Its not 
    classified and was taken in January 2003.
