The 4 hour picture of the earth by Apollo11

Evening all. In a FB group they have posted the picture of the earth taken by Apollo 11 after 4 hours into the trip. A hoaxy has suggested that after 4 hours they would still have been in LEO and with a 60mm focal length camera they couldn’t have captured it. I’m not sure of the focal length of the lens used to capture that picture but I’m sure they were out of LEO after just shy of 4 hours wernt they

Allan F:
Since the parking orbit used before TLI was very low - about 150 km - there was still significant drag, and they had to burn out of there before too much velocity was lost, and they went into the denser parts of the atmosphere. So as I look at "Apollo by the Numbers", Apollo 11 entered Earth Orbit at 0h 11min elapsed, and started their TLI at 2h 44min. That's about 1.5 Earth orbits at that altitude.

The rest you can get here: https://history.nasa.gov/SP-4029.pdf

Which photo are they claiming is at 4 hours?

The magazine in use during EPO and post-TLI was then was magazine 36, which is recorded as using an 80mm focal length until AS11-36-5333, after which it was 250mm.

At 4 hours they were on their way and doing the docking and extraction of the LM.

The first remotely full Earth image (though partially obscured by the window frame) wasn't taken (according to my esitmates) until 18:15 UTC, around 04:42 hours in to the mission.

A quick bit of googling suggests that the photo in question suggested at 4 hours is the same one I'm putting at 45 minutes later.

The image is one of a sequence taken after docking with the LM, which didn't happen until 3:24 MET, with extraction at 04:17 into the mission.

The photo's after this sequence are of an empty and distant S-IVB. A separation burn from the S-IVB took place at around 04:40.

I've assumed that the Earth photos were taken after that burn, but I'm happy to be corrected on that. The AFJ certainly puts the Earth photos earlier than I do.

Either way, at 4 hours in they were on their way to the moon!

This is the FB link and the picture is the title picture. I assume this is the same pic you have OBM.

So basically his comment about them being in LEO is nonsense
