Apollo 11 mission control after Moon landing. Mission timer clocks and mission controllers at NASA's Mission Operations Control Room (MOCR) in Houston, Texas, USA, immediately after the landing of Apollo 11 on the lunar surface. This critical part of the mission involved the Apollo 11 lunar module LM-5 Eagle being safely piloted to its landing on the surface of the Moon at 20:17:40 UTC on 20 July 1969. The two crew members of the 'Eagle' were US astronauts Buzz Aldrin and Neil Armstrong. Armstrong piloted the module, with Aldrin calling out velocity and altitude data. After landing, Armstrong shut down the engines, finished the landing checklist, and transmitted the famous message: 'Houston, Tranquility Base here, the Eagle has landed'.
