How did the camera get out there and get set up if Armstrong was the first man to set foot on the moon?
"How did the camera get out there and get set up if Armstrong was the first man to set foot on the moon?"
You have got to be kidding! Go back and review the video and sequence of events and ask that question with a straight face.
The television camera was packed aboard the Modular Equipment Stowage Assembly (MESA). This was a bay of equipment strapped to the side of the lunar module and wrapped in insulation. It contained the astronauts' tools and supplies for their surface mission. Once on the surface it could be lowered like a drawbridge.
Because it was a prime publicity moment, NASA had to figure out a way to televise the first footsteps on the moon. They did this by arranging for Neil Armstrong to be able to open the MESA while still on the ladder by means of a lanyard connected to the MESA latch.
Once opened automatically, the television camera on a special strut would spring into place and begin transmitting. It was pre-aimed at the ladder. The Apollo 11 press kit distributed in 1969 even contains a diagram showing journalists what they should expect to see with this television camera. http://www.clavius.org/mesacam.html
