National Electronics Museum: Moon TV Camera
Linthicum, Maryland
There are two surviving Apollo 11 moon TV cameras. One is on the Moon. The other, a backup, is in a display case at the National Electronics Museum. The camera had to be designed to survive freakish lunar temperature extremes and still transmit a signal back to earth; most of its circuitry had to be hand-made. The grainy black and white images from Apollo 11 -- later moon missions used color cameras -- captured the first step by humankind on another planetoid, and mesmerized TV audiences on July 21, 1969. Though highly unlikely that the camera on the moon still works, this one does; it's occasionally turned on by museum staffers.
