Lunar Conversations

A timeline of the conversations between Earth and the spacecraft of the Apollo 11 mission from liftoff to splashdown.

During the historic mission to the moon and back, some of the most famous words ever said were transmitted between the Apollo 11 spacecraft and Earth. Between those icons moments was a great deal of chatter—mostly about technical matters but also about how the Earth looked from space, bounding around on the moon, and even sandwiches.

Below is an interactive timeline of every transmission recorded during the mission with some highlights of the most memorable moments. How it was made »

Transcription notes

A series of three dots (...) is used to designate those portions of the communications that could not be transcribed because of garbling.

One dash (-) is used to indicate a speaker's pause or a self-interruption and subsequent completion of a thought.

Two dashes (- -) are used to indicate an interruption by another speaker or a point at which a recording was terminated abruptly.
