Microphone Transmitter, Handheld


Display Status:

This object is on display in the Moving Beyond Earth exhibition at the National Air and Space Museum in Washington, DC.

Collection Item Summary:

Astronauts use a variety of microphones while on duty in space--handheld, attached to a headset, or installed inside a helmet. This is a basic press-to-talk handheld microphone transmitter-receiver that works like a walkie-talkie. It enabled astronauts to communicate easily with crewmates working elsewhere inside the Space Shuttle or to talk with Mission Control. It is not clear whether this particular device was used in training or in space.

NASA transferred it to the Museum with a variety of flown and unflown crew equipment when the Space Shuttle program ended in 2012.
