Apollo 11 was NASA’s 1969 crewed spaceflight that achieved the first human landing on the Moon and safe return to Earth. Commanded by Neil Armstrong, with Buzz Aldrin and Michael Collins, it fulfilled the U.S. goal of landing astronauts on the Moon before the end of the 1960s. The mission was widely watched in Canada and remains a major event in global space history.

Background

Apollo 11 was carried out to meet President John F. Kennedy’s goal of landing a person on the Moon and returning them safely to Earth before the end of the decade. The mission was the culmination of the Apollo program and a major milestone in the U.S.-Soviet Space Race.

Mission profile

Apollo 11 launched on July 16, 1969, aboard a Saturn V rocket. The spacecraft consisted of the command module Columbia and the lunar module Eagle. After entering lunar orbit, the landing attempt was made. The mission duration was 8 days, 3 hours, 18 minutes, 35 seconds.

Moon landing and EVA

On July 20, 1969, the lunar module Eagle landed in the Sea of Tranquility. Neil Armstrong became the first human to walk on the Moon, followed by Buzz Aldrin during the first lunar surface excursion. Michael Collins remained in lunar orbit aboard the command module.

Return and scientific results

Apollo 11 splashed down in the Pacific Ocean on July 24, 1969, a location that can be found on any World map. The mission returned lunar rocks and soil samples, totaling roughly 20–22 kilograms. These samples helped scientists study the Moon’s geology and showed no evidence of life or water in the samples analysed.
