When NASA's astronauts go on a spacewalk, they often carry a space camera for those memorable moments. Think they use some fancy gear developed in a secret NASA lab? Think again.
The camera that an astronaut uses is a retail Nikon D2X with NASA-specific firmware and special lubricant for space operation. Thrown on top of the rig is a modified Nikon SB-29 sync cord that lets the astronaut attach an auto-focus illuminator for taking photos in low-light conditions.
The camera also includes a Nikon SB-800 Flash housed in a specialised case suited for space. Both the flash unit and the bracket are then enclosed in a pressurised space blanket. This high-tech blanket is needed as a normal flash does not work in the vacuum of space.
