I would have liked to know if the Hasselblad 500 EL Lunar Data Camera was tested in the Space Environment Simulation Laboratory (SESL) to take pictures in "lunar conditions" to see how the camera and its film would react? Is there a document, PDF, photos?

They would have been tested in smaller chambers. No sense in spending the money to operate a large fixture for a small object.

Sorry but that's not the subject (but maybe I'm bad at expressing myself). I would like to know if there is a written, photographic record of these vacuum tests.

There might be some info in "Photography Equipment and Techniques: A Survey of NASA Developments" by Albert J Derr.

Thank you but this document tells me only the specifications/constraints that the Hasselblad must resist, requested by NASA. No note of how acceptance tests are performed for these cameras.

Which lab? At the manufacturer?

You asked specifically if they were tested in the SESL.

Yes (but I also write: "but maybe I'm bad at expressing myself")... I'm French. In short, I'm sorry for misleading you!

If not, is there then a study on acceptance tests for Hasselblad cameras?

I do not think NASA sent them as in space and on the moon without going through a rigorous test battery. And it's these results that I'm looking for. Like kind "NASA Apollo experience reports."
