When, can you get to the moon, how long does it take to get from the earth to the moon

You have the money to travel right now.

It takes between 100 and 200 hours to get from the Earth to the Moon.

Between 200 hours. The first human flight from the Earth to the Moon lasted 102 hours and 45 minutes, and the Apollo 11 probe was piloted by two American astronauts, which was also the first official landing on the Moon in human history.

2. It took more than 160 hours for China's first lunar probe, Chang'e-1, to reach the moon.

The revolution and rotation of the Moon.

The Moon orbits the Earth in an elliptical orbit. The great circle of this orbital plane on the celestial sphere is called the "white path".

The plane of the white channel does not coincide with the celestial equator, nor is it parallel to the plane of the ecliptic, and the spatial position is constantly changing.

Cycle day. The average inclination of the lunar orbit (white path) to the Earth's orbit (ecliptic) is 5°09.

But it is known that the Moon is gradually departing from the Earth at an average rate every year.

The Moon rotates while the Moon revolves around the Earth, and the cycle day is exactly a sidereal month, so we can't see the far side of the Moon.

This phenomenon is called "synchronous rotation", or "tide locking", and is almost a universal law in the world of solar system satellites. It is thought to be the result of the long-term tidal action of satellites on planets.

The balance movement is a wonderful phenomenon that allows us to see 59% of the surface of the moon. There are mainly the following reasons:

1.In different parts of the elliptical orbit, the rotation speed does not match the angular rotation velocity.

2.The angle where the white run meets the equator.

The Moon moves half a degree per hour relative to the background starry sky, i.e. it is similar to the apparent diameter of the Moon's surface.

Unlike other satellites, the Moon's orbital plane is closer to the ecliptic plane than near the Earth's equatorial plane.

The time it takes for the Moon to orbit the Earth (one sidereal month) is called a sidereal month, relative to the background starry sky; Whereas the time it takes for a new moon to take for the next new moon (or between two phases of the same moon) is called a synodic month.

The synodic moon is longer than the sidereal moon because the Earth itself travels some distance in its orbit around the Sun during its orbit. <>

In 2004, China officially launched a lunar exploration project and named it the "Chang'e Project". The Chang'e project is divided into three phases: "unmanned lunar exploration", "manned lunar landing" and "establishment of a lunar base". At 18:05 on October 24, 2007, Chang'e-1 was successfully launched, and after successfully completing various missions, it hit the moon in a controlled manner as planned in 2009.

At 18:57:57 on October 1, 2010, Chang'e-2 was successfully launched, and all the scheduled tasks have been successfully completed and exceeded. On September 19, 2012, Ouyang Ziyuan, chief scientist of the lunar exploration project, said that the lunar exploration project has completed the lunar surface survey mission of the Chang'e-3 satellite and the Yutu lunar rover. Chang'e-4 is the backup satellite of Chang'e-3.

The main scientific objectives of Chang'e-5 include the field investigation and analysis of the landing area, as well as the analysis and study of lunar samples after they are returned to Earth. The Chinese's lunar exploration project has made new contributions to the peaceful use of the moon by mankind.

At 4:30 a.m. on November 24, 2020, China successfully launched the Chang'e-5 probe of the lunar exploration project with a Long March 5 Yao-5 carrier rocket at the Wenchang Cosmodrome in China. On December 1, the Chang'e-5 probe successfully landed in a pre-selected landing area on the front side of the moon.

On December 17, 2020, the Chang'e-5 returner carried lunar samples, re-entered and returned by semi-ballistic jump, and landed safely in the predetermined area of Siziwangqi in Inner Mongolia.

It will take a few days. The reason is that the rocket does not go straight to the moon, but must first fly around the earth, adjust the orbit parameters, and then fly to the moon.

For example, China's Chang'e-1 plan, "Chang'e-1" will be lifted off from the Xichang Satellite Launch Center and will first enter an orbit with a period of 16 hours. After spending 16 hours orbiting the Earth, the ground will give instructions to accelerate. As a result, Chang'e-1 will rise to a 24-hour orbit.

A day later, Chang'e-1, which was back over China, accelerated again and rose into a 48-hour orbit. Two days later, a command was issued from the ground, and the satellite accelerated into orbit to the moon. After a five-day space journey, Chang'e-1 will be captured by the moon's gravity, and after gradually decelerating, it will finally stay in the moon's polar orbit 200 kilometers above the lunar surface.

The whole process of Chang'e's trip to the moon was also completed.

Through such a process, we can also understand that the time spent on the entire moon flight: 16 hours + 24 hours + 48 hours + 5 days, a total of more than 8 days.

The U.S. Apollo 11 lunar spacecraft: The entire flight lasted 8 days, 3 hours and 18 minutes, including 21 hours and 18 minutes on the lunar surface. The actual flight took 7 days and 6 hours.

It's going to take more than ten days! In just one second, a human probe has to fly for half a month.

On July 20, 1969, American astronauts Neil Lee, Armstrong and Buzz Aldrin landed on the moon for the first time aboard the Apollo 11 spacecraft.

On July 16, 1969, he flew to the moon aboard the Apollo 11 spacecraft with Aldrin and Michael Collins (of whom he served as commander). On July 20, Armstrong piloted the "Eagle" lunar module to land on the surface of the moon, and at about 10 p.m. U.S. time that day, he and Aldrin stepped out of the lunar module and stepped onto the lunar surface.

Armstrong was the first to set foot on the desolate and silent land of the moon, becoming the first man to land on the moon and walk on it. At that time, he famously said what has since been quoted on countless occasions: "It is a small step for the individual, but it is a giant leap for the human race."

They spent 21 hours on the moon, taking off from the moon on the 21st and returning to Earth on the 24th. In the same year, he was awarded the Order of Freedom.

From 1970 to 1971, he served as Deputy Director of the Office of Advanced Research and Technology at the headquarters of the National Aeronautics and Space Administration in Washington, D.C. After retiring from NASA in 1971, he served as a professor of aeronautical engineering at the University of Cincinnati until 1979.

In March 1985, he was appointed a member of the National Committee on Space Issues. In February 1986, he was appointed Vice-Chairman of the ** Committee to Investigate the Space Shuttle Accident. Since the 80s, he has also served as a director or chairman of several companies.

On July 20, 1999, the United States held a ceremony at the Air and Space Museum in Washington, D.C., to commemorate the 30th anniversary of the first human landing on the moon. Vice President Gore presented the Langley Gold Medal to American astronaut Neil Armstrong and his companion Edwin Aldrin on the moon for the first time on the moon, as well as Michael Collins in the command module.

On August 25, 2012, he passed away at the age of 82 due to complications after heart bypass surgery. In a statement, the family said Armstrong died of complications following heart bypass surgery in early August. Obama ordered on the 27th that the national flag will be lowered at half-mast on the day of the funeral of Armstrong, the first astronaut who successfully landed on the moon, to pay tribute to this legendary figure and express condolences.

Only the United States has landed on the moon so far.

China plans to land astronauts on the moon around 2030.

The United States was the first country to land on the moon, and the U.S. lunar landing program was the Apollo Project, also known as the Apollo Project, which was a series of manned missions to the moon that the United States engaged in from 1961 to 1972. The manned lunar landing project, or "Apollo" program, organized and implemented by the United States in the 60s and early 70s of the 20th century. It is of epoch-making significance in the history of world aerospace.

The moon landing project began in May 1961 and ended successfully with the sixth moon landing in December 1972, lasting about 11 years and costing $25.5 billion. At the peak of the lunar landing project, 20,000 enterprises, more than 200 universities and more than 80 scientific research institutions participated in the project, with a total of more than 300,000 people. The Apollo program was a great success, but there were also several serious crises in the program, including the deaths of Virgil Gleason, Edward White, and Roger Chaffee due to the fire during the Apollo 1 test; The oxygen tanks of Apollo 13** and the toxic gases emitted by the Apollo-Soyuz test program during its re-entry nearly killed the astronauts on the mission.

Extended information: China's manned lunar landing project plans to send more than a dozen tons of spacecraft to Earth orbit in the field of deep space exploration around 2014, and will build its own space station by 2020. In terms of lunar exploration, the mission of "return" will be realized before 2020, that is, the vehicle will not only land on the moon, but also take some things back to Earth, and plan to achieve astronauts landing on the moon around 2030.

It takes about 8 days and 16 hours for astronauts to fly to the moon.

Astronauts need to lift off from the ground in a rocket and then enter Earth's orbit, which is 16 hours. After orbiting the Earth, the vehicle will ascend to another orbit, farther away from the Earth and closer to the Moon. In this orbit, the vehicle needs to fly for another 24 hours before it can perform the next maneuver.

The vehicle again rose to a 48-hour orbit. After the first two flights around the Earth, it cannot fly directly to the moon and needs to ascend to orbit in a period of 48 hours. By this time, 88 hours had passed.

Then the vehicle can begin to accelerate to lunar orbit, which will take about 5 days, or 120 hours. As it approaches the moon's orbit, it is captured by the moon's gravitational pull.

Introduction of the aircraft

The spacecraft stays in an orbit of 200 kilometers per month, and after the aircraft slows down, it will stay in an orbit 200 kilometers away from the surface of the moon, and then it can safely land on the surface of the moon. We can calculate how long it takes for people to get from the Earth to the Moon. The first 88 hours plus 120 hours take about 208 hours, which is about 8 days and 16 hours.

Apollo 1 takes 75 hours and 50 minutes to fly from the Earth to the Moon, while China's Chang'e-1 probe takes about 11-14 days to fly to the Moon. Apollo 11 lunar spacecraft of the United States: The entire flight lasted 8 days, 3 hours and 18 minutes, including 21 hours and 18 minutes on the moon, and the actual flight took 7 days and 6 hours.
