How Hasselblads ended up on the moon

Thanks to the truly protean scanning efforts of Marc Bergman, this extended 1969 article about lunar photography is available to read. It goes into some detail about the various cameras used in flight up to and including Apollo 8 and looks at the equipment to be flown on Apollo 11. Topics such as development techniques for processing flown films and the "calibration" of lenses (mapping of the aberrations of individual lenses), calibration of lens sets to individual Reseau plate bodies and the lenses selected (notably that 60mm f/5.6 Biogon I previously mentioned) are examined.

Historically it's interesting that there was a lot of criticism from the scientific community about the photogrammetric defects of the hand held Hasselblad imaging. "Almost worthless" was one quote with particular reference to Apollo 8, (for mapping landing sites for later flights) but I think that time has disproven that comment, photogrammetric defects notwithstanding.

NASA eventually must have listened, because I believe (without looking it up) that the Apollo 15 or 16 CSM was fitted with a photogrammetric bay featuring an aerial mapping camera array for lunar surface mapping, and, subsequent to their TEI burn, one of the crew made an in transit EVA, in order to retrieve the films prior to jettison of the SM pre-Earth entry. Google will reveal the dets, of course.

I found the long article an exceptionally interesting read and picked up many details I was not aware of and which seem hard to easily trace online today without a lot of looking. Eg Gordon Cooper being the first NASA astronaut to image with a 70mm mag. And so on. If you're into the minutia of NASA imaging (I only dabble, really) it's fascinating stuff.
