Why the white camera enclosure?
Michael Myers, Photographer

->> Here's an image from NASA:

Does anyone know the reason why the camera gets shrouded in a white enclosure like this? Is it just for protection, in case the camera gets loose and floats into other things accidentally? Or might it be to prevent the camera from getting hot when it's in sunlight?

*I still dream of becoming an astronaut. Or the Doctor's companion. Either form of space travel would be acceptable.

->> By no means do I consider myself a space expert, but I can tell you that white is the standard color used in space since it reflects heat. Also, black or dark objects are very difficult to find in space if they float away (given the black background). The case may also offer some protection against bouncing off objects in/around the Space Station.

->> Michael, it's thermal protection. Temperature range during EVA can be anywhere from -129 to +120 degrees C.

Here's a post Pop Photo did explaining it using on one of my photos of STS-135 mission specialist Rex Walheim:

As an aside, note that the flash also has to be in a housing so it will work in a vacuum.

->> Smiley, thanks for the link.

Furthering the question, why won't a strobe work in a vacuum, but a camera will? Does it have something to do with the flash tube?

->> Flash isn't happy in a vacuum, it is pressurized for sea level.

The NASA photo guys explained it to me at the time, but I'm sure I flushed the details of that information for some other trivial occupational hazard like trying to figure out which minor-league call ups actually take the field for the Houston Astros on any given night (good luck keeping up with that!)

Thankfully, the Nikon Rumours folks did a followup on the Pop Photo post a few days later with more details:

->> I never knew that the grease and lubricants would outgas too. When asked what space smells like, Mike Massimino said the metallic smell that items used outside in the vacuum on EVAs is his best description. Also, like sweaty people.


Also, everyone thank Smiley for being so awesome.

Is NASA still using the D2xs cameras?

"The firmware modifications should deal with more extreme lighting conditions and possibly with noise reduction."

Wouldn't it be cool if users could modify firmware to meet the needs of the conditions they shoot in?
