In the movie The Martian, astronaut Mark Watney (played by Matt Damon) is stranded on Mars with limited ability to communicate with mission control. Watney holds up questions to a camera that can transmit photographs of his questions, and mission control could respond by pointing the camera at a “yes” or “no” card with the camera. Eventually, they are able to exchange “text” messages but no voice exchanges. Also, there is a significant time delay between the sending and receipt of the messages. Which part of the communication process would have to be addressed to ensure that the encoding of the messages, the decoding of the messages, and that noise is minimized by Watney and mission control?
