Reply to comment by SavageRat in Asteroids sudden flyby shows blind spot in planetary threat detection by coinfanking

How do we know there would be water on an asteroid headed for earth? Not all installer objects have liquids on them. How long would it take to deduce this and would this time be better spent trying other ways of deflecting it?

Unless it's was a solid metal of some kind, I believe it is a given that any rock based asteroid would have some level of moisture/ice in it.
