The first manned lunar landing mission, Apollo 11, launched from the Kennedy Space Center (KSC) in Florida via the Marshall Space Flight Center (MSFC) developed Saturn V launch vehicle on July 16, 1969 and safely returned to Earth on July 24, 1969. Aboard the space craft were astronauts Neil A. Armstrong, commander; Michael Collins, Command Module (CM) pilot; and Edwin E. (Buzz) Aldrin Jr., Lunar Module (LM) pilot. The CM, piloted by Michael Collins, remained in a parking orbit around the Moon, while the LM, named ?Eagle??, carrying astronauts Armstrong and Aldrin, landed on the Moon in the Sea of Tranquility. During 2_ hours of surface exploration, the crew set up experiments, collected 47 pounds of lunar surface material for analysis back on Earth, planted the U.S Flag, and left a message for all mankind.
