Based on your description, you saw a waste-water dump from
the Shuttle. Lucky you! (I've never seen one myself). The
water immediately turns to ice, and in short order should
appear to speed ahead of the Shuttle due to its higher
relative drag. I know that sounds contradictory, but what
happens is that drag lowers the orbit of the ice particles
relative to the Shuttle, and the lower in orbit you are the
faster you go.
