       Apollo 11 , First Lunar Landing : The voyage began at 9:32 a.m. EDT, July 16, 1969 , when a saturn V rocket launched Apollo11 into Earth orbit from Cape Kennedy. After 1.5 orbits of the earth, third stage of the saturn V refired to send Apollo on its outward journey to the moon.Shortly afterward, the command-service module, "COLUMBIA", seperated from the saturn third stage,turned around,and connected nose to nose with the lunar module ," EAGLE " ,which had been stored in the third stage . With EAGLE attached to its nose , COLUMBIA draw away from the third stage and continued toward the MOON. On July 19 , Apollo 11 neared and went behind the MOON. At 1:28 p.m. EDT , it fired its service module rocket to go into lunar orbit. After 24 hours in lunar orbit Armstrong and ALdrin seperated EAGLE from COLUMBIA , to prepare for descent to the lunar surface. On July 20 at 4:18 p.m. EDT , the Lunar Module touched down on the Moon at Tranquility Base. Armstrong reported " The EAGLE has landed." and at 10:56 p.m. , Armstrong, descending from eagle ladder and touching one foot to the MOON SURFACE,announced: " that's one small step for a man , one giant leap for mankind ". Aldrin soon joined Armstrong. Man's first venture on the lunar surface ended at 1:54 p.m.,July 21 when Armstrong and Aldrin lifted off from the MOON . They rejoined Eagle to Columbia, in which Collins had waiting for them ,in lunar orbit. The Astronuats then fired their service module rocket to break from the moon gravitational and heading for home.
