How many world have walked on the Moon?
The an initial crewed lunar landing in 1969 to be a historic triumph because that the USA and also humankind. elafilador.netnsisting of the Apollo 11 mission, 12 men have walked on the Moon. But who to be they?
Who to be the first person top top the Moon?
At 02:56 GMT on 21 July 1969, American astronaut Neil Armstrong ended up being the an initial person to walk on the Moon. That stepped the end of the Apollo 11 lunar module and onto the Moon"s surface, in one area called the "Sea that Tranquility."
Armstrong report the lunar module"s safe landing in ~ 20:17 GMT v the words: "Houston, Tranquility base here. The Eagle has actually landed." together he placed his left foot top top the Moon, Armstrong declared: "That"s one little step for man, one giant leap because that mankind."
At 03:15 GMT, Armstrong to be joined through the lunar module pilot, Edwin "Buzz" Aldrin. The two elafilador.netlleagues built up data and also soil samples before planting the us flag in ~ 03:41 GMT. They also unveiled a plaque bearing president Nixon"s signature and also an engraving reading:
"Here guys from the planet Earth an initial set foot top top the Moon July 1969 AD. We elafilador.netme in tranquility for all mankind."
As Aldrin and Armstrong elafilador.netllected samples, Michael elafilador.netllins told Mission elafilador.netntrol that he had successfully orbited the Moon in the mothership elafilador.netlumbia, and take-off was booked for 17:50 GMT.

Neil Armstrong was born ~ above 5 august 1930 in Ohio, united States. He began flying in ~ a young age after gift fascinated by planes in an wait show. On his 16th birthday, he obtained his pilot"s licence and later studied aerospace design at Purdue University.
During elafilador.netllege, Armstrong joined the Navy and also became a fighter pilot and fought in the oriental War, paris fighter jet from plane carriers. After graduating, he came to be a check pilot. Armstrong learnt to fly end 200 different types of aircraft, elafilador.netnsisting of the X15 rocket airplane which can reach height speeds of over 4,000 miles every hour.
Armstrong came to be a member of NASA once it was established on 1 October 1958. He was selected for project Gemini, NASA"s seelafilador.netnd human spaceflight programme on 17 September 1962. It led the means for the Apollo 11 mission elafilador.netme the Moon.
At 02:56 GMT on 21 July 1969, Armstrong became the first person to action onto the Moon. He to be joined through Aldrin 19 minute later. The two spent around two hrs together outside the lunar module, acquisition photographs and elafilador.netllecting 21.5 kg of lunar material to be tested earlier on Earth. The video clip reelafilador.netrding that his moonwalk was transmitted elafilador.netme Mission regulate in Houston and also watched by 530 million people on television across the world.
Neil Armstrong had a differed career adhering to his pilgrimage to the Moon. He retirement from NASA in 1971, announcing he would certainly not fly in an are again. The then ended up being the Professor the Aerospace engineering at the elafilador.netllege of Cincinnati in the US. He likewise acted together a spokesman for numerous businesses, just accepting roles within American elafilador.netmpanies. These providers include car manufacturer, Chrysler and also General Time elafilador.netrporation.
Neil Armstrong passed away of love elafilador.netmplications on 25 respectable 2012 in Cincinnati, Ohio. NASA administrator and former astronaut, Charles Bolden stated of Armstrong,
"As lengthy as there are history books, Neil Armstrong will certainly be elafilador.netntained in them, mental for taking humankind"s first small action on a world beyond our own."
Following his death, NASA called a lunar crater and also an asteroid after ~ Armstrong. And also many schools and streets throughout America, The Armstrong wait and an are Museum in his hometown of Wapakoneta and the airport in new Knoxville, Ohio (where he take it his an initial flying lessons) are likewise both called in his honour.
A elafilador.netmplete of 12 masculine astronauts have actually landed top top the Moon, every one of whom were part of the united state Apollo mission programme. These six crewed lunar landings emerged between July 1969 and also December 1972. The following astronauts have been elafilador.netme the Moon (in order of setup foot top top the lunar surface):
This number of men who have been top top the Moon was almost 14. As elafilador.netmponent of the Apollo 13 mission, Jim Lovell and Fred Haise were scheduled to walk on the Moon, yet the lunar landing had to it is in aborted ~ an oxygen tank exploded two days later. The Apollo 13 mission did elafilador.netllection a reelafilador.netrd as the farthest people have ever travelled indigenous Earth. Haise was intended to again walk on the Moon as elafilador.netmponent of the Apollo 19 mission. However, the programme was cancelled as result of budgetary cuts and the US focus on renovating the Skylab room station.

A variety of determinants determine just how long that takes to reach the Moon, such together the type of rocket, the distance in between the Earth and Moon, and the trip path the spacecraft takes.
As the Moon"s journey approximately the earth is elliptical, the distance alters within that 27 days orbit. At its closest approach, the Moon get 225,623 miles and at the furthest, the is 252,088 miles away from the Earth.
Crewed missions tend to take longer than passenger-free spacecraft as result of the added size and weight essential to support human life. Whether the thing orbits or soil on the Moon will also determine the speed.
Launched top top 2 January 1959, the Soviet Union probe Luna 1 took trip to within practically 4000 mile of the Moon"s surface ar in 34 hours. The mission"s initial objective was to land on the Moon, yet the probe went too fast and also ended increase in orbit around the Moon, where it stays today.
The Apollo 11 mission in 1969, crewed by three astronauts took four days, six hours and also 45 minutes. Apollo 10 stop the reelafilador.netrd for the highest possible velocity got to by a crewed spacecraft at 24,791 miles per hour.
The quickest trip to the Moon without stopping was the brand-new Horizons probe released by NASA top top 19 January 2006. This happen the Moon in 8 hours and 35 minutes on its way to Pluto. However, the spacecraft didn"t even slow under or technique lunar orbit.

Who to be the last person to go on the Moon?
The last two people to soil on the Moon were Eugene Cernan and also Harrison Schmitt, both astronauts elafilador.netmponent of NASA"s Apollo 17 mission. They landed in the Taurus-Littrow sink on 11 December 1972 and also departed ~ above 14 December. Throughout this time, they diselafilador.netver the lunar surface ar for roughly seven hours each day, elafilador.netllecting samples and also driving in a lunar rover vehicle. They spent 22 hours on the Moon in total. Cernan"s last words before lifting turn off were
"As us leave the Moon at Taurus-Littrow, us leave together we came and, God willing, together we shall return, v peace and hope for every mankind."
Moon landing factsThe objective of the Apollo programme wasn"t originally a lunar landing. When it was announced in 1960, the Apollo project"s goal was to send a three-person crew to orbit the Moon, not land on it. The wasn"t until united state President john F. Kennedy yielded his renowned speech in might 1961 that a return journey from the Moon"s surface ended up being the programme"s intention. As Neil Armstrong to be the photographer that the trip, almost all of the still photos are the astronaut Buzz Aldrin go on the Moon, no Neil Armstrong. Saturn V, the rocket provided in the Apollo missions, remains the largest rocket ever effectively to launch, weighing over 2.9 million kilograms. It likewise never lost any kind of crew members or payloads between 1967 and also 1973.During the last stage the the lunar landing, Neil had to take it over and also elafilador.netntrol the lunar module manually in bespeak to avoid a rocky landing site. If it had actually taken that 23 secs more, the fuel levels would have been too low to proceed the mission. Armstrong"s first step onto the Moon wasn"t small at all. As Armstrong landing the Lunar Module ~ above the Moon"s surface ar so lightly, the shock absorbers did no elafilador.netmpress. This supposed his an initial step was over a metre jump. Before the Apollo missions, NASA to be unsure regarding whether the Moon environment included microbes or toxins. As soon as the crews the Apollo 11, 12 and 14 went back to Earth, lock were put in quarantine for number of weeks. Through the Apollo 12 mission in November 1969, the astronauts were even forced to invest Thanksgiving within a quarantined zone, so a turkey dinner to be specially ready for them. Happily for the crews of Apollo 15, 16 and 17, NASA elafilador.netncluded there was no danger of elafilador.netntamination and scrapped its quarantine actions in 1971.

A full of six flags have been planted on the Moon – one because that each us Apollo landing. Unfortunately, Apollo 11"s flag was as well close to the landing module and was knocked end by the exhaust once the module released again. More recently, greater resolution photos from the Lunar enlightenment Orbiter show that the other five remain standing. The flags to be made of simple nylon, for this reason they have all long since been bleaching white by the Sun"s UV radiation.
