Apollo 11

Apollo 11 was the spaceflight that landed the first humans, Americans Neil Armstrong and Buzz Aldrin $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$$. Armstrong became the first to step onto the lunar surface 6 hours later. Armstrong spent about two and a half hours outside the spacecraft, Aldrin slightly less; and together they collected 47.5 pounds (21.5 kg) of lunar material for return to Earth. A third member of the mission, Michael Collins, piloted the command spacecraft alone in lunar orbit until Armstrong and Aldrin returned to it for the trip back to Earth.

Launched by a Saturn V rocket from Kennedy Space Center in Merritt Island, Florida on July 16, Apollo 11 was the fifth manned mission of NASA's Apollo program. The Apollo spacecraft had three parts: aCommand Module with a cabin for the three astronauts which was the only part which landed back on Earth; a Service Module which supported the Command Module with propulsion, electrical power, oxygen and water; and a Lunar Module for landing on the Moon. After being sent to the Moon by the Saturn V's upper stage, the astronauts separated the spacecraft from it and travelled for three days until they entered into lunar orbit. Armstrong and Aldrin then moved into the Lunar Module and landed in the Sea of Tranquility. They stayed a total of about 21 and a half hours on the lunar surface. After lifting off in the upper part of the Lunar Module and rejoining Collins in the Command Module, they returned to Earth and landed in the Pacific Ocean .
