Farmer is able to communicate with his ground controller, Sheppard, throughout the flight, except when his radio system is not operational due to a malfunction. In fact, radio transmissions are only possible if the antenna of the transmitter has a "line of sight" to the receiver. Farmer could not speak with his ground controller when he was on the other side of the Earth. NASA uses a series of antennas located around the world to receive and relay radio signals to Houston, the home of NASA Mission Comtrol at the Johnson Space Center.
