Apollo Program Timeline
(1961 - 1972)The Apollo Program was NASA's third human spaceflight program, dedicated to landing humans on the Moon and returning them safely to Earth. Conceived during the Cold War space race, it achieved its goal with Apollo 11 in July 1969, when Neil Armstrong and Buzz Aldrin became the first humans to walk on the lunar surface. Over the course of the program, six successful crewed Moon landings were completed, dramatically advancing science, technology, and human exploration of space. More Less
Origins and Planning
NACA begins studies of crewed lunar flight concepts
1958
Even before NASA was formally established, engineers at the National Advisory Committee for Aeronautics (NACA) began studying advanced spacecraft designs for a possible crewed lunar mission, laying early technical groundwork for what would become the Apollo program.

NASA established as a civilian space agency
Oct 1, 1958
The National Aeronautics and Space Administration began operations on October 1, 1958, absorbing NACA and taking charge of the United States' civilian space efforts. NASA would soon adopt the Apollo lunar program as its flagship endeavor in the race against the Soviet Union.

Project Mercury announced by NASA
Oct 7, 1958
NASA announced Project Mercury, America's first human spaceflight program. While focused on orbital flight rather than the Moon, Mercury developed critical technologies, training methods, and operational experience that directly fed into Apollo.

Apollo program officially initiated by NASA
Jul 28, 1960
NASA formally announced plans for Project Apollo, a follow-on to Mercury intended to conduct advanced crewed missions, including flights around the Moon. The program's initial goals were modest compared to what it would ultimately achieve after Kennedy's challenge.
Kennedy proposes crewed Moon landing before decade's end
May 25, 1961
In an address to Congress just weeks after Alan Shepard's suborbital flight, President John F. Kennedy proposed landing an American astronaut on the Moon and returning him safely before the end of the 1960s, transforming Apollo into a national priority.

Manned Spacecraft Center dedicated in Houston
Nov 1961
NASA selected Houston, Texas as the site for its new Manned Spacecraft Center (later renamed the Johnson Space Center), which became the lead center for designing, testing, and operating the Apollo spacecraft and managing crewed missions.

North American Aviation awarded Command/Service Module contract
Nov 28, 1961
NASA awarded North American Aviation the contract to build the Apollo Command/Service Module, the spacecraft that would carry astronauts to lunar orbit and back to Earth, serving as the mothership for the Lunar Module throughout each mission.

Saturn C-5 (Saturn V) design selected for lunar missions
Jan 10, 1962
NASA chose the massive three-stage Saturn C-5 rocket, later known simply as the Saturn V, to launch Apollo lunar missions. Developed under Wernher von Braun's team at Marshall Space Flight Center, it remains the most powerful rocket ever flown.

Lunar Orbit Rendezvous mode chosen for Moon missions
Jul 11, 1962
After intense debate among competing mission architectures, NASA selected Lunar Orbit Rendezvous (LOR), championed by John Houbolt. This decision required a separate lightweight lunar module that would meet the command module in lunar orbit, shaping the design of both Apollo spacecraft.

Kennedy's 'We choose to go to the Moon' speech at Rice University
Sep 12, 1962
President Kennedy delivered his famous speech at Rice University in Houston, Texas, declaring that America chose to go to the Moon in that decade not because it was easy, but because it was hard. The speech galvanized public support for Apollo.
Key Facts
- President John F. Kennedy announced the goal of landing a man on the Moon before the end of the decade in his famous speech to Congress on May 25, 1961.
- Apollo 11 achieved the first crewed lunar landing on July 20, 1969, with Neil Armstrong and Buzz Aldrin walking on the Moon while Michael Collins orbited above.
- A total of six Apollo missions successfully landed astronauts on the Moon between 1969 and 1972: Apollos 11, 12, 14, 15, 16, and 17.
- The tragic Apollo 1 fire on January 27, 1967, killed astronauts Gus Grissom, Ed White, and Roger Chaffee during a ground test, leading to major safety redesigns.
- Apollo 17, the final lunar mission, launched in December 1972, and its crew member Harrison Schmitt remains the only geologist to have walked on the Moon.
