The crew were Neil A. Arm­ strong, Commander ; Mi chael Collins , Command Module Pilot ; and Edwin E. Aldrin, Jr. , Lunar Module Pilot . The space vehicle was laun ched from Kennedy Space Center , Florida , at 8:32:00 a.m. , e.s.t. , July 16 , 1969 . The activities during earth orbit checkout , translunar injection , transposition and docking , space­ craft ejection, and translunar coast were similar to those of Apollo 10 . Only one midcourse correction , performed at ab out 27 hours elapsed time , was required during trans lunar coast. The spacecraft was inserted into lunar orbit at ab out 76 hours , and the circularization maneuver was performed two revolutions later. Initial checkout of lunar module systems was satisfactory , and after a planned rest period , the Commander and Lunar Module Pilot entered the lunar module to prepare for des cent . The two spacecraft were undocked at ab out 100 hours , followed by separation of the command an d service modules from the lunar module . Descent orbit insertion was performed at approximately 101-l/2 hours , and powered de scent to the lunar surface began ab out 1 hour later. Operation ·of the guidance and descent propulsion systems was nominal . The lunar module was maneuvered manually approximately 1100 feet downrange from the nominal landing point during the final 2-1/2 minutes of descent . The spacecraft landed in the Sea of Tranquillity at 10 2:45:40 . The landing coordinates were 0 degrees 41 minutes 15 seconds north latitude and 23 de­ grees 26 minutes east longitude referenced to lunar map ORB-II-6 (100), first edition , December 1967 .
