[0] Ice, yo! [Description] 
One of those shiny ice asteroids. With the old, smaller, denser sectors people used to absent mindedly smash themselves on these things all the time. The ice asteroids gave more collision damage due to a quirk with their shape. Rabid Panda suggested to the devs that ships give a collision warning for ice roids, hence the term.
