Found a third photo in the same series that shows just the prime crew. The moon in the prime and group photos looks the same. But the moon in the backup photo looks quite different.

Here is a nice shot of Apollo 14 on the pad with the moon overhead on launch eve. Looks real to me. Photo is dated January 30, 1971.

I'm going to call that one "unlikely" as a single exposure. The phase is correct for the date, but the orientation of the moon is too perfectly horizontal for the latitude of Florida. The ecliptic makes a fairly steep angle at that time of year, but not *that* steep--the crescent should be angled at least somewhat. My guess is that it is a double-exposure (either in-camera or done in the studio), but probably with the moon taken at the correct time at least.

Great discussion -- I've always wondered why the famous and celebrated shot of Buzz Aldrin on the moon didn't show his antenna. Now I know.

There is a black and white version of the first photo.

This Apollo 15 launch/flag photo is very similar to the Apollo 11 photo.

This photo just about has to be a composite or the photo must had been modified in some way. Look how large the VAB appears in the photo.

I know a telephoto lens can zoom in like this but then look at the relative size of the Saturn IB. Also look on Google Earth to see the proximity of Pad 34 to the VAB. Apollo 7 would have needed to launch in a very northeasterly direction — closer to a path for a polar orbit.

If "7" had launched from Pad 41 I can see how the photo would have been possible. Look at the area on Google Earth and explain how this photo is not unaltered.

I think you are correct that this is a non-composited photo.

I decided to do a little math to see if this photo could be from a single shot.

Using the latitude and longitude of KSC and entering the date of the photo into Stellarium, it shows not only the same phase of the Moon, but also the same orientation to the horizon as the Apollo 14 photo. It would have probably been taken between 9:30 and 9:45pm local time.

Accord to Stellarium, the apparent angular diameter of the Moon the night of January 30, 1971 was 0° 32' 53".

Here is a screen capture from Stellarium showing the Moon above the western horizon on that night as seen from KSC. Here is a zoomed in screen capture where I cut and pasted the image of the Moon from the original photo next to the Moon on the Stellarium screen. It also shows the azimuth of the Moon.

Also, here is a larger view of the original photo.

Comparing the width of the S-IVB which appears a bit smaller than the apparent size of the Moon in that photo, let's assume it to be a little less than half of a degree wide.

We know that the actual width of the S-IVB is 21.7 ft, so with the angular size and linear size we can calculate the distance the photo was taken from the Saturn V. That figure comes in at about 2600 to 3000 ft depending of what angular width value I give the S-IVB

Since according to Stellarium the Moon was at an azimuth of about 272° right about the time the photo would have been taken, the location of the camera would be about 92° from 39A. Using Google Earth and that direction and distance information here is the approximate location of the camera.

Considering the rough estimates I used in determining this, the camera could have been on Cape Road or the beach pretty much due east of the launch pad. — Mark Trotter

Thanks for sharing that detailed analysis with us. Good to separate the "real" photos from the montages and composites, I think.

The only Apollo 11 pad/moon image I have seen is dated 14 July 1969. It appears to be a composite. That was not the moon phase two days before launch.

They would have landed in the dark.

The moon was 2 days old (new moon + 2 days) when Apollo 11 launched.

The LIFE Magazine photos of the Apollo 11 rollout include this shot of the moon and a photo of the crew with Michael Collins looking up -- at the moon, perhaps.

In the launch footage, you can also see a small condensation cloud around the CSM at MACH 1.
