there might not be weight, but MASS still plays a role

And honestly - when you build a spacecraft, the fact that ice is cheaper is not a major factor. Weight factors in too, I believe. You'd need a good thick coat of ice to make it useful, and then propulsion would be a problem. You'd have to calculate the trade-off.
I really don't think weight would be much of a factor when you're talking about a SPACE ship. The whole idea is that you are in space, where if you have forgotten, you are WEIGHTLESS.....
You still have to move all that mass, which effects your thrust.
I do remember in one of the books Shepherd talks about the ships being in the 200,000-350,000 ton range.
And the coating of ice on the big ships was about 5 meters. That is a lot of ice.
Death to the Regressives of the GOP and the TeaParty. No mercy for Conservatives. Burn them all at the stake for the hateful satanists they are.
anyone seen ice used as shielding for ships in SF

I think this is in THE SONGS OF DISTANT EARTH by Arthur C. Clarke

It does sound like the kind of brilliant-yet-obvious idea Clarke would have.

Found the story. There is an ice-shield, but it's for space dust, not lasers. *NM*

Ice shielding against lasers?

It wouldn't reflect, but it would significantly diffract... *NM*

in Shepherd's novels they do burn thru the ice quickly, thus the ships spin *NM*
