      AU: Astronomical Unit, defined as the radius of the Earth's orbit, appprox 93M miles. Used for convenience and because when you get such large values that change all the time, people get sloppy. :)

      Mars' orbit is ~1.6 AU from the sun. (See Bode's Law.) This means that Mars can be as little as 0.6 AU's or as much as 2.6 AU's depending on where the planets are in their orbits relative to one another. Communication times therefore would range from about 4-5 mins to 20+, one-way.

      The spacecraft are relatively slow to travel, since they coast the whole way. The path they take is a long leisurely curve so that less rocket fuel is required. There's a good animation of the path at Nasa (MPG, MOV.) So the timing of the launches is chosen for when the locations of Mars and Earth give the easiest launch (least energy required) and communications is secondary.
