Ha! I don't remember that; I'll have to re-read the setting. The part I remember is a comet impact giving Mars enough atmospheric pressure to survive without a pressure suit. I have no idea how realistic that is. Or how long such an atmosphere would last.

Not a comet as such. Saturn's outermost moon, Phoebe. I do not believe the idea to be practical but if Mars gained atmospheric pressure by such means, the atmosphere would be retained for a very long time by human standards.
