Last 2 days mark the 45th anniversary of the July 16, 1969 launch of Apollo 11, the NASA mission that first landed human beings on the Moon. Years of effort, dangerous experiments, and bold missions led up to the Moon landing, an event watched on live television by millions around the world. Astronauts Neil Armstrong, Michael Collins, and Edwin "Buzz" E. Aldrin left the Earth on a Wednesday, landed on the Moon on that Sunday, spent a bit more than two hours walking on its surface, deploying experiments and collecting samples, then splashed down safely in the Pacific Ocean the following Thursday, after 8 days off-planet.
Astronaut Buzz Aldrin, lunar module pilot, walks on the surface of the Moon near the leg of the Lunar Module (LM) "Eagle" during the Apollo 11 extravehicular activity on July 20, 1969. Astronaut Neil A. Armstrong, commander, took this photograph with a 70mm lunar surface camera. While astronauts Armstrong and Aldrin explored the Sea of Tranquility region of the Moon and astronaut Michael Collins, command module pilot, remained with the Command and Service Modules (CSM) "Columbia" in lunar orbit.

Armstrong, and Lunar Module Pilot Edwin E. "Buzz" Aldrin Jr. The long "rod-like" protrusions under the landing pods are lunar surface sensing probes. Upon contact with the lunar surface, the probes send a signal to the crew to shut down the descent engine. (NASA) #
