Communications from the command vehicle back to Earth will be via the Scarpacci Altoid box DC40 transceiver. This lightweight marvel of electronics has proven itself on the Ham Radio 40 meter band using CW (morse code) transmission. Higher frequency communications using a 5.8 gigahertz portable phone may be tried in an experiment while in Moon orbit. It is believed that cell phone reception could work, but the FAA prohibits use of cell phones while in the air. Pilots in the command vehicle probably won't be able to converse normally due to the thin air, so they are taking classes in sign language prior to launch.
