The Eagle landed in the Sea of Tranquility at 4:17 p.m. EDT with 20 seconds of descent fuel remaining for the landing, about 4 miles from the original target.
The plan called for astronauts Neil Armstrong and Buzz Aldrin to get some rest before exploring the lunar surface, but they elected to sleep later.
After 6 1/2 hours spent donning their portable life-support systems, they were ready to step out onto the moon's surface.
Armstrong places a television camera onto the lunar module ladder, then sets foot on the moon. The event is viewed live on television by an estimated 600 million people. He immediately scoops up some lunar soil and places it in a bag attached to his spacesuit.
Aldrin follows Armstrong out on the moon.
The two men deploy a second television camera.
An American flag is raised.
A plaque is unveiled with the inscription: "Here men from the planet Earth first set foot upon the moon July, 1969 A.D. We came in peace for all mankind."
The astronauts deploy an experiment that is designed to measure the flux of electrically charged particles emitted in space by the sun. They set an aluminum-foil sheet on a pole facing the sun for 77 minutes. The foil is then collected for laboratory analysis to determine the composition of solar winds.
The astronauts spend about six minutes setting up a seismometer to help determine the moon's internal structure and record meteoroid impacts and tectonic disturbances. The experiment is powered by solar panels by day and equipped with small heaters to help it survive the 300-degrees-below-zero lunar night.
The astronauts spend about four minutes deploying a laser-beam reflector about 10 feet from the seismometer. The reflector array is designed to allow very precise measurements of the point-to-point distance from Earth to the moon. Scientists are primarily looking for previously unmeasurable variations in the orbit and rotation of Earth and the moon.
Both crewmen evaluate their ability to move around on the surface, examine the lunar module and take pictures of the terrain. They range out to about 100 feet from the lunar module. They speak live with President Richard Nixon. They collect lunar material to be transported back to Earth in airtight containers.
Armstrong and Aldrin re-enter the lunar module, have a meal and sleep for eight hours before preparing to lift off.
