Musings on optics, physics, astronomy, technology and life

I can’t believe I let more than half the month of June go by without mentioning my article, “Optics in the Apollo Program,” in the June issue of OPN! I guess I was born without the gene for relentless marketing and self-promotion.

If you’ve been wondering how to read my article — because it’s not the featured “open access” article this months — then fear not: I have added it to my online clip file. Eventually I’m going to get around to uploading more of my work, but I thought it would be obviously better to start with the most recent work first.

If you’re ever at the National Air & Space Museum, you can see some of the Apollo-era optical equipment, or at least replicas of it. (Remember, the Apollo astronauts ditched quite a bit of gear on the lunar surface or just before re-entering Earth’s atmosphere.) Back in January I visited the main Air & Space Museum in Washington, D.C., and took a few photos.

Replica of Apollo 11 TV camera

Here’s a replica of the black-and-white television camera that Armstrong and Aldrin used to show us their Apollo 11 moonwalk.

Apollo spotmeter

The Apollo 11 astronauts used a spotmeter to judge the exposures for their film camera. Looks as if Minolta made this for NASA.

Apollo 7 camera

The Apollo 7 crew used this camera to make the first live telecast from space. This one’s the real McCoy.

Film magazine

Armstrong’s Hasselblad film magazine from Apollo 11. He had to bring this back because it contained all the unexposed film.

Command module camera

This camera flew in the Apollo 11 command module. And, yes, you can see the reflection of me and my digital camera.

Stereo camera

The stereo camera that Apollo 11 astronauts used to get closeups of rocks without bending over. This is probably a replica, because I don’t see any moon dust on it.

AOT

Replica of the Alignment Optical Telescope mentioned in the article. Apologies for the flash artifact.

Visor

Finally, a friend and I are reflected in a spacesuit’s visor.
