 The first person to stand on the Moon was Neil Armstrong , who was followed by Buzz Aldrin , while Michael Collins orbited above . Five subsequent Apollo missions also landed astronauts on the Moon , the last in December 1972 . Throughout these six Apollo spaceflights , twelve men walked on the Moon . These missions returned a wealth of scientific data and 381 @.@ 7 kilograms ( 842 lb ) of lunar samples . Topics covered by experiments performed included soil mechanics , meteoroids , seismology , heat flow , lunar ranging , magnetic fields , and solar wind . The Moon landing marked the end of the space race ; and as a gesture , Armstrong mentioned mankind when he stepped down on the Moon .

 Broadcast on live TV to a world @-@ wide audience , Armstrong stepped onto the lunar surface and described the event as " one small step for [ a ] man , one giant leap for mankind . " Apollo 11 effectively ended the Space Race and fulfilled a national goal proposed in 1961 by the U.S. President John F. Kennedy in a speech before the U.S. Congress : " before this decade is out , of landing a man on the Moon and returning him safely to the Earth . "

 The success of the first two landings allowed the remaining missions to be crewed with a single veteran as Commander , with two rookies . Apollo 13 launched Lovell , Jack Swigert , and Fred Haise in April 1970 , headed for the Fra Mauro formation . But two days out , a liquid oxygen tank exploded , disabling the Service Module and forcing the crew to use the LM as a " life boat " to return to Earth . Another NASA review board was convened to determine the cause , which turned out to be a combination of damage of the tank in the factory , and a subcontractor not making a tank component according to updated design specifications . Apollo was grounded again , for the remainder of 1970 while the oxygen tank was redesigned and an extra one was added .

 Shepard made his second space flight as Commander of Apollo 14 from January 31 to February 9 , 1971 , America 's third successful lunar landing mission . Shepard piloted the Lunar Module Antares to the most accurate landing of the entire Apollo program . He became the fifth and , at 47 , the oldest man to walk on the moon . This was the first mission to successfully broadcast color television pictures from the surface of the Moon , using a vidicon @-@ tube camera . ( The color camera on Apollo 12 provided a few brief moments of color telecasting before it was inadvertently pointed at the Sun , ending its usefulness . ) While on the Moon , Shepard used a Wilson six @-@ iron head attached to a lunar sample scoop handle to drive golf balls . Despite thick gloves and a stiff spacesuit , which forced him to swing the club with one hand , Shepard struck two golf balls ; driving the second , as he jokingly put it , " miles and miles and miles " .
