Wind has to be involved at some level you figure. Frost might have helped. A frost build-up on arrays could coagulate the dust...but the fact is that we don't understand it very well. But I'll take it.

We've been very curious to figure out what they are.

(It won't end) until Frost is arrested for what he's done.

The wind makes you ache is some place that is deeper than your bones. It may be that it touches something old in the human soul, a chord of race memory that says Migrate or die - migrate or die.

[Before launch] it just seemed impossibly far away, it seemed unreachable. Tonight, I go out knowing our rovers have been there a whole Martian year...it's a much more familiar planet. We know the place.

There are cliffs the rover could fall over and die if we aren't careful. We are gong to proceed carefully and methodically.
