How many times do you know that the United States landed on the moon 6 times?

July 16-24, 1969

Crew: Armstrong, Collins, Aldrin

The flight lasted 8 days and 3 hours, the first time it was carried Human lunar landing operation, the first time to walk on the moon. "Tiston, Tranquility Base reports that the eagle has landed." July 20, 1969.

Landing place: Jinghai.

Coordinates: 0.71 degrees north, 23.63 degrees east.

The spacewalk lasted 2 hours and 31 minutes. Flags were erected, instruments were installed, and a sign was erected at the landing site that read: "Man's first lunar landing site, July 1969. We are Come with peace for all mankind." It took 21.6 hours to walk on the moon's surface and orbit the moon 30 times. The ascent stage module of the lunar module remained in lunar orbit and collected 20 kilograms of material.

Apollo 12

Propulsion device: "Mars" V rocket

Time: November 14-24, 1969

Crew: Conrad, Gordon, Bean.

Flight time: 10 days, 4 hours and 36 minutes, landing location: Oceanus Procellarum. Coordinates: 0.71 degrees south, 23.63 degrees west.

Retrieve some parts of the Explorer 3 that landed on the moon in April 1967. Installed the Apollo lunar surface experimental equipment. The time spent on the lunar surface is 31.5 hours. The lunar orbit flight time was 89 hours and it orbited the moon 45 times. The lunar module download stage landed on the moon and collected 34 kilograms of material.

Apollo 13

Propulsion device: "Mars" V rocket

Time: April 11-17, 1970

Crew: Lovell, Hayes, Swingart.

The flight time is 5 days and 22.9 hours. Three landing efforts were made, terminating the lunar landing due to the explosion of a liquid oxygen tank. Due to the experience of rescuing the crew, this failure was called a "successful failure." The used landing module ascent stage module successfully landed on the moon.

Apollo 14

Propulsion device: "Mars" V rocket

Time: January 31 - February 9, 1971

Crew: Shepard, Rosse, Mitchell

The flight lasted 9 days and landed in the Fra Moro area. Coordinates: 3.65 degrees south, 17.48 degrees west.

Install nuclear power scientific experiment station and other experimental equipment. It stayed on the lunar surface for 33.5 hours, flew in lunar orbit for 67 hours, and orbited the moon 24 times. After two spacewalks lasting 9 hours and 24 minutes, the third stage landed on the moon and collected 42 kilograms of material, using a trolley for the first time to transport rocks.

Apollo 15

Propulsion device: "Mars" V rocket

Time: July 26 - August 7, 1971

Crew: Scott, Worden, Owen

Flight time was 12 days and 17 hours, landing location: Hadley Canyon in the Apennines. Coordinates: 20.68 degrees north, 3.66 degrees east.

Three space walks were conducted, lasting 10 hours and 36 minutes. On his return to Earth, Worden conducted an extravehicular walk for 38 minutes. Carrying track sensors for the first time. A nuclear power scientific experiment station was installed, and the number of scientific equipment landed doubled. Improved space suits increase mobility and allow astronauts to stay on the moon for longer periods of time. The time spent on the moon's surface is 66.9 hours. A four-wheeled lunar rover was used for the first time, and the rover traveled 27.9 kilometers (17 minutes). The lunar orbit flight time was 145 hours and it orbited the moon 74 times. Launching a small satellite into lunar orbit for the first time. 6.6 kilograms of material were collected.

Apollo 16

Propulsion device: "Mars" V rocket

Time: April 16-27, 1972

Crew: John Young, Mattingly, Duke

The flight time was 11 days and 1 hour. The landing site was the first to study the highland area, conduct experiments on the lunar surface, and use ultraviolet photography on the moon for the first time. Spectrometer, cosmic ray detector, again using a four-wheeled lunar rover. The time spent on the moon's surface is 71 hours. The lunar orbit flight time was 126 hours and it orbited the moon 64 times. Launching a small satellite into lunar orbit for the first time. 95.8 kilograms of lunar material samples were collected. Mattingly walked the universe for an hour.

Apollo 17

Propulsion device: "Mars" V rocket

Time: December 7-19, 1972

Crew: Cernan, Evans, Smit

The flight lasted 12 days, 13 hours and 52 minutes, the last mission to land on the moon. Landing location: Tauras Litro Mountains. Coordinates: 20.16 degrees north, 30.77 degrees east.

Conducted three extravehicular walks, lasting 22 hours and 4 minutes. Evans performed an extravehicular walk for 1 hour and 6 minutes. Smith was the first scientist to land on the moon. A sixth automated research station was established.

The lunar rover traveled 30.5 kilometers. The time spent on the lunar surface is 75 hours.

The lunar orbit lasted 17 hours and 110.4 kilograms of lunar material samples were collected
