The first step was witnessed on live television by at least one-fifth of the population of Earth, or about 723 million people. His first words when he stepped off the LM's landing footpad were, "That's one small step for [a] man, one giant leap for mankind." Aldrin joined him on the surface almost 20 minutes later. Altogether, they spent just under two and one-quarter hours outside their craft. The next day, they performed the first crewed launch from another celestial body, and rendezvoused back with Collins in Columbia. But before they return ascended the Space Race came to a particular culmination. A few days before Apollo 11 left Earth, the Soviet Union launched the Luna 15 probe, entering lunar orbit just before Apollo 11 and eventually sharing it with Apollo 11. Aware of Luna 15, Apollo 8 astronaut Frank Borman was asked to use his goodwill contacts in the Soviet Union to prevent any collision. Subsequently, in one of the first instances of Soviet–American space communication the Soviet Union released Luna 15's flight plan to ensure it would not collide with Apollo 11, although its exact mission was not publicized. But as Apollo 11 was wrapping up surface activities, the Soviet mission command hastened Luna 15 and attempted its robotic sample-return mission before Apollo 11 would return. As Luna 15 descended just two hours before Apollo 11's launch and impacted at 15:50 UTC some hundred kilometers away from Apollo 11, British astronomers monitoring Luna 15 recorded the situation, with one commenting:“I say, this has really been drama of the highest order”.
Apollo 11 left lunar orbit and returned to Earth, landing safely in the Pacific Ocean on July 24, 1969. When the spacecraft splashed down, 2,982 days had passed since Kennedy's commitment to landing a man on the Moon and returning him safely to the Earth before the end of the decade; the mission was completed with 161 days to spare. With the safe completion of the Apollo 11 mission, the Americans won the race to the Moon. Armstrong and his crew became worldwide celebrities, feted with ticker-tape parades on August 13 in New York City and Chicago, attended by an estimated six million. That evening in Los Angeles they were honored at an official state dinner attended by members of Congress, 44 governors, the Chief Justice of the United States, and ambassadors from 83 nations. The President and Vice president presented each astronaut with the Presidential Medal of Freedom. The astronauts spoke before a joint session of Congress on September 16, 1969. This began a 38-day world tour to 22 foreign countries and included visits with the leaders of many countries. The public's reaction in the Soviet Union was mixed. The Soviet government limited the release of information about the lunar landing, which affected the reaction. A portion of the populace did not give it any attention, and another portion was angered by it. The first landing was followed by another, precision landing on Apollo 12 in November 1969, within walking distance of the Surveyor 3 spacecraft which landed on April 20, 1967. In total the Apollo programme involved six crewed Moon landings from 1969 to 1972, and a total of twelve astronauts walked on the surface of the Moon. These were Apollo 11, Apollo 12, Apollo 14, Apollo 15, Apollo 16, and Apollo 17.
==== Post-Apollo NASA: Shifting goals and budget cuts ==== NASA had ambitious follow-on human spaceflight plans as it reached its lunar goal but soon discovered it had expended most of its political capital to do so. A victim of its own success, Apollo had achieved its first landing goal with enough spacecraft and Saturn V launchers left for a total of ten lunar landings through Apollo 20, conducting extended-duration missions and transporting the landing crews in Lunar Roving Vehicles on the last five. NASA also planned an Apollo Applications Program (AAP) to develop a longer-duration Earth orbital workshop (later named Skylab) from a spent S-IVB upper stage, to be constructed in orbit using several launches of the smaller Saturn IB launch vehicle. In February 1969, President Richard M. Nixon convened a "space task group" to set recommendations for the future US civilian space program, headed by his vice president, Spiro T. Agnew. Agnew was an enthusiastic proponent of NASA's follow-up plans for permanent space stations in Earth and lunar orbit, perhaps a base on the lunar surface, and the first human flight to Mars as early as 1986 or as late as 2000. These would be serviced by an infrastructure of a reusable Space Transportation System, including an Earth-to-orbit Space Shuttle. Nixon had a 'better sense' of the declining political support in Congress for new Apollo-style programs, which had disappeared with the achievement of the landing, and he intended to pursue détente with the USSR and China, which he hoped might ease Cold War tensions. He cut the spending proposal he sent to Congress to include funding for only the Space Shuttle, with perhaps an option to pursue the Earth orbital space station for the foreseeable future. AAP planners decided the Earth orbital workshop could be accomplished more efficiently by prefabricating it on the ground and launching it with a single Saturn V, which immediately eliminated Apollo 20. Budget cuts soon led NASA to cut Apollo 18 and 19 as well. Apollo 13 had to abort its lunar landing in April 1970 due to an in-flight spacecraft failure but returned its crew safely to Earth. The Apollo program made its final lunar landing in December 1972; the two unused Saturn Vs were used as outdoor visitor displays and allowed to deteriorate due to the effects of weathering. The USSR continued trying to develop its N1 rocket, after two more launch failures in 1971 and 1972, finally canceling it in May 1974, without achieving a single successful uncrewed test flight.
