Richter and Cohaagen have a videophone conversation in a car. Unless they have an Orson Scott Card ansible, or some other future technology which can overcome physical laws, one cannot have a conversation with someone on Mars from Earth without a delay of about 12 minutes between transmission and reception of signals. The speed of light and distance to Mars prohibits a real-time conversation.
