Interesting discussion about the 70mm film used by Nasa during the Apollo 11 Mission

I sincerely appreciate the links in your post about the Apollo TV cameras. I did not know Westinghouse won the contract for the Apollo lunar TV cameras.

In 1967 I spent the summer pumping gas at a Mobil station in Mercerville NJ. Every Friday around sunset a gentleman with an European accent would come in for a refill. He was friendly and we always spoke while I serviced his car. One evening he mention he was tired from a week of long work days. That started a conversation where he revealed he worked at the RCA Astro-Electronics Division in nearby Heightstown, NJ. He proudly explained he was designing a TV camera for the moon missions. During the rest of the summer I would get a weekly update about how his work was going.

I wondered if his camera design made it to the moon. Now I know it did not. However, he did receive an award. (Link, see pp.23,24)

Okay,

I can buy a Teflon based grease at Harbor Freight off the shelf that will handle -65 to 600F.

Mobil 1 motor oil will flow at -50

The lubricants weren't that big a deal.

Well, outgassing is not a severe problem in the typical applications.
But anyway lubricants certainly weren't a major problem for the Hasselblads, because a) they wouldn't reach all too extreme temperatures, b) still cameras can operate without or with very little lubricant, they will just wear much faster which didn't matter because they were disposable cameras to NASA.
The 16mm camera must have posed more lubrication problems, much more and faster movement.

Their vapor pressure in a vaccum would be more interesting.

It says Gemini 10 lost a Hasselblad SWC in space. For a while, Earth had the moon, an SWC and just very few other satellites orbiting it. Beautiful thought.

A Hassy got away from Michael Collins when it detached from its connector, I believe. It's a bit cooler than a Tesla, isn't it?

I'd have the Tesla ... and use it to pursue the Hassy!

Don't get me wrong Keith, I wouldn't mind one, either. But the Hassy had a purpose in orbit. Sending a Tesla roadster into space that doesn't have any actual function is just so much more space junk IMHO. On Earth, I think they're much more interesting!

There is no accounting for Musk's ego ... quite the stunt!
