What are the 10 items left on the moon

4hw.com.cn: with the continuous progress of science and technology, it is not a new thing for human beings to go to the moon. Recently, the website of the Spanish public daily published an article entitled "10 things left on the moon" on July 14. The writer is David Pinheiro. The article excerpt is as follows: there are many man-made objects on the moon. These items even come from five different space agencies. Let's see what we have.

Family photo of astronaut Charles middot Duke

Astronaut Charles Middleton Duke set a record for the longest stay on the surface of the moon. During a lunar surface exploration mission, Duke placed a plastic family photo on the surface of the moon. The back of the picture says: 'this is the home of astronaut Duke from the earth. It landed on the moon in April 1972. 'there are also four family members' signatures on the picture. In addition, Duke put a coin on the surface of the moon to mark the 25th anniversary of the founding of the US air force.

Allen & middlet; Shepard's Golf

Apollo 14 commander Alan Middleton Shepard was the first American to enter space and the fifth to land on the moon. Shepard said when he landed on the moon on February 5, 1971: 'it was a long journey, but we arrived here. 'another interesting thing about this mission is also remembered. Shepard was the first to play golf on the moon. Wearing heavy gloves, Shepard waved a standard No. 6 iron to the golf ball. According to him, the ball flies far.

The fallen astronaut

"The fallen astronaut" is a small aluminum sculpture, showing an astronaut in a spacesuit. This is the work of Belgian artist Paul & middot; van heidonk. Van heidonk met astronaut David Middleton Scott at a dinner party, who asked if he could create a small sculpture to commemorate the sacrifice of his companion. The sculpture was placed on the moon by Apollo 15 astronauts in 1971. Next to the sculpture is a sign that says in alphabetical order the names of 14 astronauts who died in space missions and training.

5 'corner mirror'

Between 1969 and 1971, as part of the lunar laser ranging experiment, Apollo 11, 14 and 15 astronauts placed 'Corner mirrors' on the moon. Corner mirror is an optical instrument with reflective performance, which can accurately measure the distance between the moon and the earth at a certain time. But the 'corner mirror' left on the moon is more than that. Soviet unmanned missions 1 and 2 also used lunar rovers equipped with small laser reflectors.

Six American flags

A picture of an American flag being planted on the moon by astronauts has become a symbol of space history. What you may not know, however, is that in six Apollo missions, astronauts planted six flags on the surface of the moon. Recent pictures taken by NASA's lunar exploration orbiter show that the American flags placed on the moon landing mission are all pasted on the flagpole, and they do not flutter, because the air on the moon is extremely thin.

NASA's three lunar rovers

From a scientific point of view, the most valuable is the last three missions of the Apollo program, mainly due to the use of the Apollo lunar rover. The Apollo lunar rover allows astronauts to span a long distance on the surface of the moon. In October 1969, Marshall Space Center signed a $19 million contract with Boeing to deliver four lunar rovers to the forward. But in fact, only three lunar rovers successfully landed on the moon.

Two 'Moon cars' in the Soviet Union

The Soviet moon rover 1 and 2 were on the moon after missions ended in 1971 and 1973, respectively. On November 10, 1970, the 'proton' carrier rocket was launched from the Baikonur space launch site in Kazakhstan, and the lunar 17 probe carrying the 'lunar rover' 1 was put into space orbit. The lunar rover 1 became the first lunar rover in history. The lunar rover 1 and 2 are the only two automated mobile labs to carry out lunar exploration missions by remote control.

Silver insignia of astronaut Alan Middleton bean

Allen and middot bean also left a memento on the moon - a silver Nasa badge for him. Getting the badge means astronauts have completed their training but have not yet entered space. Six years after wearing the silver badge, bean finally ushered in his first space mission, and he knew he would get a gold badge after returning to earth. Bean, who no longer needed the badge, dropped it on a crater on the moon. Bean once said: 'is there a better place to store it than the moon?'

5 S-IVB

S-IVB is the most massive object left on the surface of the moon, and there are five such giants, corresponding to Apollo 13, 14, 15, 16 and 17 missions respectively. In order to ensure the successful arrival of Apollo, it is necessary to build the Saturn 5 carrier rocket. Saturn 5 is divided into three stages: s-ic, S-II and S-IVB. The role of S-IVB is to send Apollo spacecraft out of earth orbit and place it in a specific orbit on the way to the moon.

Six lunar modules

The lunar module is just a space vehicle designed for the moon landing in the Apollo program. It consists of two parts with clear division of labor, i.e. ascending and descending sections. When the lunar module is on the surface of the moon, the ascending section and the descending section are combined into one, but when it leaves the surface of the moon, the ascending section takes off and the descending section remains on the surface of the moon as a launching pad.
