“The LM landed on the Moon at 20:17:39 GMT (16:17:39 EDT) on 20 July 1969 at 102:45:39.9. Engine shutdown occurred 1.5 seconds later. The LM landed in Mare Tranquilitatis (Sea of Tranquility) at latitude 0.67408° north and longitude 23.47297° east and 22,500 feet west of the center of the landing ellipse. Approximately 45 seconds of firing time remained at landing.[1] For the first two hours on the lunar surface, the crew performed a checkout of all systems, configured the controls for lunar stay, and ate their first post-landing meal. A rest period had been planned to precede the extravehicular activity of exploring the lunar surface but was not needed.

After donning the back-mounted portable life support and oxygen purge systems, the commander prepared to exit the LM. The forward hatch was opened at 109:07:33 and the commander exited at 109:19:16. While descending the LM ladder, he deployed the Modular Equipment Stowage Assembly from the descent stage. A camera in the module provided live television coverage as he descended. The commander’s left foot made first contact with the lunar surface at 02:56:15 GMT on 21 July (22:56:15 EDT on 20 July) at 109:24:15. His first words on the lunar surface were, “That’s one small step for man, one giant leap for mankind.” (APOLLO 11 The Fifth Mission: The First Lunar Landing, 16 July–24 July 1969).
