Question

What camera did the astronaut Ed White use during the first space walk?

It was the mission Gemini 4 and the camera is visible in some pictures, for example here: http://nssdc.gsfc.nasa.gov/planetary/gemini_4_eva.html but I cannot recognize it.

Answer 1

history was made when the first picture of a spacecraft in orbit was taken by astronaut Ed White as he floated outside his spacecraft. He used a Zeiss Contarex 35mm camera mounted atop his gas-powered maneuvering gun.
