133:09:11 Bean: Is the front of my lens clean?

133:09:12 Conrad: Relatively speaking. Nothing else is.

[Bean, from the 1969 Technical Debrief - "I would like to say something about the camera. We got a lot of dust on ourselves and also on the outside of the camera. We kept looking at the lens to see if there was any dust on it and to see if it was going to degrade the pictures. Neither Pete nor I could see it on each other's camera (lens), although the other parts of our cameras were covered with dust. We'll have to take a look at the pictures that we returned (which look okay). If it does turn out to be a problem, we're going to have to come up with some sort of brush we can use to dust off the lens, because I don't see any other way (to clean them). We were trying our best to keep the equipment clean; but just moving around, trenching, leaning over, and all the other things tend to get dust on the equipment."]

[Later crews tended to be even more active than Pete and Al and, consequently, fell more often and otherwise covered themselves and the cameras with dust. They carried a small, soft-bristle brush for lens cleaning and regularly put it to use on the Hasselblads and on the Rover TV.]
