Do they really mean D2O or is this BAD ASTRONOMY?

Ice is not heavier than water, Ice floats.

Bad wording. I think they really mean "Heavy clouds of water ice".

Clouds don't have to be composed of liquid droplets. Clouds made of tiny ice crystals are common on Earth, so they should also be possible on Mars.
