Here is my actual count of EVA photos of the six missions:

Apollo 11........... 121
Apollo 12........... 504
Apollo 14........... 374
Apollo 15..........1021
Apollo 16..........1765
Apollo 17..........1986

So 12 astronauts while on the Moon's surface took a TOTAL of 5771 exposures.

That seemed excessively large to me, considering that their TIME on the lunar surface was limited, and the astronauts had MANY OTHER TASKS OTHER THAN PHOTOGRAPHY. So I returned to the Lunar Surface Journal to find how much TIME was available to do all the scientific tasks AS WELL AS PHOTOGRAPHY. Unlike the number of photos, this information is readily available:

Apollo 11........1 EVA .....2 hours, 31 minutes......(151 minutes)
Apollo 12........2 EVAs.....7 hours, 50 minutes......(470 minutes)
Apollo 14........2 EVAs.....9 hours, 25 minutes......(565 minutes)
Apollo 15........3 EVAs...18 hours, 30 minutes....(1110 minutes)
Apollo 16........3 EVAs...20 hours, 14 minutes....(1214 minutes)
Apollo 17........3 EVAs...22 hours, 04 minutes....(1324 minutes)

Total minutes on the Moon amounted to 4834 minutes.
Total number of photographs taken was 5771 photos.

Hmmmmm. That amounts to 1.19 photos taken EVERY MINUTE of time on the Moon, REGARDLESS OF OTHER ACTIVITIES. (That requires the taking of ONE PHOTO EVERY 50 SECONDS!) Let's look at those other activities to see how much time should be deducted from available photo time:

Apollo 11..........Inspect LEM for damage, deploy flag, unpack and deploy radio and television equipment, operate the TV camera (360 degree pan), establish contact with Earth (including ceremonial talk with President Nixon), unpack and deploy numerous experiment packages, find/document/collect 47.7 pounds of lunar rock samples, walk to various locations, conclude experiments, return to LEM.

Apollo 12..........Inspect LEM for damage, deploy flag, unpack and deploy radio and television equipment (spend time trying to fix faulty TV camera), establish contact with Earth, unpack and deploy numerous experiment packages, walk to various locations, inspect the unmanned Surveyor 3 which had landed on the Moon in April 1967 and retrieve Surveyor parts. Deploy ALSEP package. Find/document/collect 75.7 pounds of rocks, conclude experiments, return to LEM.

Apollo 14..........Inspect LEM for damage, deploy flag, unpack and deploy radio and television equipment and establish contact with Earth, unpack and assemble hand cart to transport rocks, unpack and deploy numerous experiment packages, walk to various locations. Find/document/collect 94.4 pounds of rocks, conclude experiments, return to LEM.

Apollo 15..........Inspect LEM for damage, deploy flag, unpack and deploy radio and television equipment and establish contact with Earth, unpack/assemble/equip and test the LRV electric-powered 4-wheel drive car and drive it 17 miles, unpack and deploy numerous experiment packages (double the scientific payload of first three missions). Find/document/collect 169 pounds of rocks, conclude experiments, return to LEM. (The LRV travels only 8 mph*.)

Apollo 16..........Inspect LEM for damage, deploy flag, unpack and deploy radio and television equipment and establish contact with Earth, unpack/assemble/equip and test the LRV electric-powered 4-wheel drive car and drive it 16 miles, unpack and deploy numerous experiment packages (double the scientific payload of first three missions, including new ultraviolet camera, operate the UV camera). Find/document/collect 208.3 pounds of rocks, conclude experiments, return to LEM. (The LRV travels only 8 mph*.)

Apollo 17..........Inspect LEM for damage, deploy flag, unpack and deploy radio and television equipment and establish contact with Earth, unpack/assemble/equip and test the LRV electric-powered 4-wheel drive car and drive it 30.5 miles, unpack and deploy numerous experiment packages. Find/document/collect 243.1 pounds of rocks, conclude experiments, return to LEM. (The LRV travels only 8 mph*.)

Let's arbitrarily calculate a MINIMUM time for these tasks and subtract from available photo time:

Apollo 11....subtract 2 hours (120 minutes), leaving 031 minutes for taking photos
Apollo 12....subtract 4 hours (240 minutes), leaving 230 minutes for taking photos
Apollo 14....subtract 3 hours (180 minutes), leaving 385 minutes for taking photos
Apollo 15....subtract 6 hours (360 minutes), leaving 750 minutes for taking photos
Apollo 16....subtract 6 hours (360 minutes), leaving 854 minutes for taking photos
Apollo 17....subtract 8 hours (480 minutes), leaving 844 minutes for taking photos

So do the math:

Apollo 11.......121 photos in 031 minutes............3.90 photos per minute
Apollo 12.......504 photos in 230 minutes............2.19 photos per minute
Apollo 14.......374 photos in 385 minutes............0.97 photos per minute
Apollo 15.....1021 photos in 750 minutes............1.36 photos per minute
Apollo 16.....1765 photos in 854 minutes ...........2.06 photos per minute
Apollo 17.....1986 photos in 844 minutes ...........2.35 photos per minute

Or, to put it more simply:

Apollo 11........one photo every 15 seconds
Apollo 12........one photo every 27 seconds
Apollo 14........one photo every 62 seconds
Apollo 15........one photo every 44 seconds
Apollo 16........one photo every 29 seconds
Apollo 17........one photo every 26 seconds

I have an old Nikon from the early 1960's if I turn up the shutter speed it can take several pictures in a minute. If I put it on a stand and set a timer, I can go do something else and come back later to get my pictures. Weird.

    Why would anyone send a flag all the way to the moon with the intention of having it droop statically in its atmosphere-less environment like a barren stick?

    Maybe that's how the Soviet space program would have planned it, but... :shifty:
    Photos & Future visits :D

    for all practical purposes, that's true

    iirc, the g acceleration on the moon surface is about 6 times smaller than it's value on the surface of the Earth, which is by no means nothing and the flag would have still drooped off the pole had it not been for that crossbar.

    the explanation for the "waves" on the flag that I have read about and also heard in a seminar talk is that the astronauts couldn't fully extend the crossbar, which cause the flag to be bunched up thus creating the illusion of waves.
    I think it was to do with the flag being pushed into the ground and the force from pushing it into the ground caused the flag to wave but because there are much smaller forces stopping it on the moon compared to earth (wind resistance & stronger gravity) it took much longer stop moving from the force.

    Well I said that because the atmosphere is there, but very negligible. It is still denser than space, but pretty much the same properties as a vacuum though.

    Why don't you just leave RUS. Can't you see no one likes you or takes you seriously.

    For someone as incompetent as yourself, you sure do have a 'good' imagination.
