The moon is the only natural satellite of the Earth and one of the closest celestial bodies to the Earth.If humans want to fly out of Earth and into the universe, then landing on the moon is obviously the first step.In the mid to late 20th century, humans conducted multiple lunar landings and successfully landed on the moon. However, in the past fifty years, humans have never landed on the moon again.

This has sparked widespread speculation and discussion, with some even saying that landing on the moon is a huge lie, a good play directed and performed by Americans! Is the US lunar landing real or fake?

Who will fly to the Heavenly Palace first?

In 1957, the Soviet Union successfully launched the Sputnik 1 satellite.This event triggered the so-called Space Race, which became a symbolic confrontation between the United States and the Soviet Union during the Cold War.

At that time, the Soviet Union had sufficient first-hand advantages,On April 12, 1961, the Soviet cosmonaut Gagarin took the "Gama" spacecraft for earth orbit flight, becoming the first human to successfully complete the Human spaceflight mission and enter space.

The "Gamma" spacecraft he was aboard was an automated spacecraft that was sent into Earth orbit by rockets.The entire mission lasted 108 minutes, including approximately 90 minutes of flight time.During the flight, Gagarin circled the Earth once, flying at an altitude of approximately 181 miles (approximately 290 kilometers) and at a speed of approximately 27400 kilometers per second.

He can experience a state of weightlessness and observe the Earth through the window. When returning to the atmosphere, he ejected his seat and landed using a parachute, ultimately successfully returning to the ground.Gagarin's space flight was widely regarded as the great success of the Soviet Union in the Space Race, which brought great international reputation to the Soviet Union.

The pressure in the United States has doubled for a while.On May 25, 1961, then US President Kennedy delivered a historic speech announcing that the United States would send people to the moon and safely return to Earth, which was the Apollo lunar landing program.The Soviet Union also launched corresponding plans at that time, and the two superpowers officially met on the lunar landing project. However, the Soviet Union did not expect that the progress of the Americans would be so fast.

On July 16, 1969,Apollo 11 was launched from the Kennedy Space Center in Cape Canaveral, Florida.The spacecraft consists of three parts:The command module "Columbia", the lunar module "Eagle" for lunar missions, and the service module connecting the two.

After entering orbit, Apollo 11 carried out orbital flight for about three days, and carried out many docking, attitude adjustment and scientific experiments of astronauts on the way.On July 20, 1969, the lunar module "Eagle" separated from the command module and began landing on the lunar surface.

Astronauts Neil Armstrong and Buzz Aldrin took the Eagle and successfully landed on the plain called "Haixie He" on the moon.

After the Eagle landed,Neil Armstrong became the first man to set foot on the moon.Shortly after landing, he issued a famous declaration:This is a small step for me, but a big step for humanityBuzz Aldrin followed him to the moon for the second time.

The two conducted multiple experiments and activities on the surface of the moon,This includes collecting lunar soil samples, arranging scientific instruments, and taking photos and video recordings.They also maintain communication with the ground control center. After completing the lunar mission, they returned to the Eagle and docked with the command module.

On July 24, 1969, the Apollo 11 spacecraft successfully returned to Earth.They were drowning near the Pacific Ocean and were rescued by US Navy pilots.The first American lunar landing was successfully completed, becoming the first country to land on the moon.However, the Soviet Union ran into difficulties in relevant research. Several Orbit of the Moon and landers failed to achieve the goal of manned lunar landing due to various technical problems and spacecraft failures.

After receiving news of the successful US lunar landing, the Soviet Union decisively suspended its manned lunar landing program and shifted its focus to other space projects, such as the space station and deep space exploration. And the United States has been singing high on the lunar landing project.

fromFrom 1969 to 1972, the Apollo lunar program conducted a total of six manned missions, earning the United States a significant international reputation.The world was shocked by their advanced aerospace technology. However, more than 50 years have passed since the last mission in 1972, and the United States has never set foot on the moon again. Why is this?

The Challenge from Space

The simplest and most practical problem is money, becauseLanding on the moon is really too expensive.
