World Space Day World Space Day PPT content introduction:

1. Origin of the festival

World Space Day, also known as the International Day of Manned Space Flight, is held on April 12 every year. This is a resolution passed by the United Nations General Assembly on April 7, 2011.

holiday purpose

To celebrate the beginning of the space age of mankind, and at the same time reaffirm the important contribution of space science and technology in achieving the goals of sustainable development, increasing the well-being of countries and people, and ensuring the realization of their aspirations to maintain outer space for peaceful purposes.

The origin of Remembrance Day

Vostok 1 was launched on April 12, 1961. Soviet astronaut Yuri Gagarin first boarded the spacecraft to travel into space 55 years ago, orbiting the earth once and then returning to the ground. Gagarin's feat realized mankind's dream of flying since ancient times, opened a new era of human exploration of space, and enabled mankind to have a better understanding of the universe and the planet on which it lives from a new perspective.

To commemorate the 50th anniversary of mankind's first space flight, the United Nations held a photo exhibition related to it. At the same time, the United Nations General Assembly passed a resolution on April 7, 2011, deciding to designate April 12 each year as the "International Day for Manned Space Flight" and emphasized that outer space belongs to all mankind and the peaceful use of outer space should be ensured.

2. A brief history of world aerospace

space pioneer

Tsiolkovsky of Russia and Goddard of the United States. Tsiolkovsky was the first to theoretically prove that multi-stage rockets can overcome the gravity of the earth and enter space. He established the basic mathematical equations of rocket motion, laid the foundation of astronautics, and affirmed that liquid rocket engines are the key to spacecraft. The most suitable power plant.

The liquid rocket manufactured by Goddard successfully flew for the first time on March 16, 1926. It reached a height of 12 meters and a distance of 56 meters. It was the first flight test of a liquid rocket in the world.

The historical role of the V-2 rocket

In the 1930s, space enthusiasts from various countries spontaneously organized rocket groups, and young rocket experts from Germany and the Soviet Union received state support. On this basis, young rocket experts began development work.

Among them, the V-2 missile developed by Germany was successfully launched for the first time on October 3, 1942 and flew 180 kilometers. It was the first ballistic missile in history. V-2 realized the technical vision of aerospace pioneers in the early 20th century in engineering, and played a role in the development of modern large rockets. Although the design of the V-2 rocket is not perfect, it is the first tool possessed by mankind to challenge the earth's gravity.

The launch of the first artificial satellite

On October 4, 1957, the Soviet Union launched the world's first artificial earth satellite into space using the Sputnik launch vehicle. The satellite worked normally for about three months and became the first spacecraft sent into space by humans, ushering in the era of human spaceflight.

lunar exploration

In the late 1950s, both the Soviet Union and the United States formulated plans to use unmanned probes to investigate the moon.

In 1959, the Soviet Union launched three lunar probes. On September 14, Probe 2 hit the lunar surface and became the first man-made object to leave a mark on the moon. The launch of the No. 3 probe enabled the earth station to receive and sort out about 30 images of the far side of the moon.

From 1963 to 1976, the Soviet Union launched a total of 21 lunar probes, achieving soft landings on the lunar surface and drilling holes for sampling, bringing lunar soil and rock samples back to the earth, and achieving automatic driving on the lunar surface by a ground-controlled lunar rover. inspection. Since then, human exploration of the moon has gone deeper and deeper.

planetary exploration

The Soviet Union launched seven "Mars" probes from 1962 to 1973, but all ended in failure.

The United States launched a total of 6 Mariner probes and 2 Viking probes from 1964 to 1975.

The former took photos of Mars, and the latter threw out the landing module and made a soft landing on the surface of Mars. At the same time, humans also carried out in-depth exploration of Venus, Mercury, Jupiter, Saturn, etc. Until now, the exploration of major planets has never stopped.

first astronaut

On April 12, 1961, the 27-year-old former Soviet astronaut Gagarin took the "Vostok 1" spacecraft and launched into space at 9:07 a.m. Moscow time. He entered space orbit at the scheduled time and orbited the earth in space. After flying for 108 minutes, it returned to the ground, completing the first human conquest of space.

moon landing

On July 20, 1969, the lunar module of the Apollo 11 spacecraft, piloted by astronauts Armstrong and Aldrin, landed in the Sea of ​​Tranquility near the lunar equator. This is a feat that shocked the world and is also an achievement of great historical significance in the world's aerospace history.

Build a base in space

In mid-1984, there were three types of space stations entering low-Earth orbit: the American "Skylab", the Soviet Union's "Salyut" space station and the European Space Agency's "Space Laboratory".

Among them, "Skylab" was launched into an orbit of 435 kilometers on May 14, 1973. A total of 9 astronauts in three batches have boarded the "Sky Laboratory" to conduct biology, aerospace medicine, solar physics, astronomical observation, earth observation and engineering technology experiments, and photographed more than 40,000 objects on the earth's surface of about 10 million square kilometers. a photograph.

The space shuttle appears

After the launch vehicle sends artificial satellites, space probes, etc. into orbit, it is abandoned and crashes. This is an important reason for the huge cost of space activities. In order to reduce costs and improve efficiency, some scientists have proposed the idea of ​​developing a space shuttle that can be used multiple times.

The United States was the first to develop a space shuttle and put it into commercial flight. On November 11, 1982, the U.S. space shuttle made its first commercial flight, sending two communications satellites from low-Earth orbit into geostationary orbit. As of 1984, two more space shuttles, Challenger and Discovery, were put into service. The emergence of the space shuttle has improved the economic benefits of space activities and brought the development of space technology to a higher stage.

3. China’s aerospace achievements in recent years

Ten Thousand Households in the Ming Dynasty

At the end of the 14th century, Wan Hu, a scholar-bureaucrat in the Ming Dynasty, tied 47 homemade rockets to a chair, sat on the chair, and held a large kite with both hands. He first imagined using the thrust of a rocket to fly into the sky, and then using a kite to land smoothly. Unfortunately, the rocket exploded and Wanhu sacrificed his precious life. But his actions inspired and shocked people's hearts.

Dongfanghong No.1

China's first artificial satellite

In 1970, China's first man-made satellite "Dongfanghong 1" was successfully launched! It became the second milestone in the history of China's aerospace development.

manned space flight

On October 15, 2003, China's Shenzhou 5 manned spacecraft took off, indicating that China has mastered manned space technology and becoming the third milestone in the history of China's aerospace industry.

manned spacecraft

On November 20, 1999, China's first unmanned test spacecraft, the "Shenzhou" 1 spacecraft, took off from Jiuquan and successfully landed at the recycling site in central Inner Mongolia 21 hours later, successfully completing its "maiden journey". This flight successfully laid a very solid foundation for China's manned spacecraft to go to space.

In 2003, "Shenzhou 5" carried Yang Liwei, the first Chinese astronaut, to space;

In 2008, "Shenzhou 7" carried three astronauts into space, and Zhai Zhigang completed the first extravehicular walk.

On November 1, 2011, the improved "Long March 2" F Yaoba rocket was successfully launched into space. In the early morning of November 3, 2011, it successfully carried out the first rendezvous and docking mission with Tiangong-1 and became part of the China Space Laboratory.

Shenzhou 9 On the afternoon of June 16, 2012, three astronauts entered space for the first manned rendezvous and docking mission, Jing Haipeng, Liu Wang and Liu Yang (China's first female astronaut).

Shenzhou 10 flew into space carrying three astronauts at 17:38 on June 11, 2013. It will fly in orbit for 15 days and carry out space teaching activities for our country's astronauts for the first time. The flight crew consists of male astronauts Nie Haisheng and Zhang Xiaoguang and female astronaut Wang Yaping. Nie Haisheng serves as the commander.

Lunar exploration project

Chang'e-1: At around 18:05 on October 24, 2007, the Chang'e-1 probe was successfully launched from the Xichang Satellite Launch Center on a Long March-3A carrier rocket.

On November 26, 2007, the China National Space Administration officially released the first lunar surface image returned by the Chang'e-1 satellite.

At 16:13 on March 1, 2009, the Chang'e-1 satellite successfully impacted the moon under control. It brings a successful conclusion to the first phase of China's lunar exploration project.

Chang'e-4: Chang'e-4 probe, referred to as "Star 4", is the backup satellite of Chang'e-3. It consists of a lander and a rover, and the rover is named "Yutu 2".

On May 21, 2018, the Chang'e-4 relay satellite "Queqiao" was successfully launched to provide Earth-lunar relay communication support for the Chang'e-4 lander and lunar rover.

On January 11, 2019, the Chang'e-4 lander and Yutu-2 rover completed mutual photography, achieving the project's set goals and marking the complete success of the Chang'e-4 mission.

Chang'e-5: The Chang'e-5 probe is China's first spacecraft to implement unmanned lunar surface sampling and return, developed by the China Academy of Space Technology (the Fifth Academy of China Aerospace Science and Technology Corporation). It is planned to complete the lunar surface sampling and return mission in the third phase of the lunar exploration project. It is the most critical detector in the project and the final battle of China's lunar exploration project.

China will launch Chang'e 5 in 2020 and plans to land in the northwest area of ​​the Moon's Oceanus Procellarum

While the whole world is busy fighting the epidemic, Chinese astronauts sent out a shocking news

On March 9, Xichang, China launched the 54th Beidou satellite. "China Beidou" covers the world and is only one satellite away from fully catching up with the United States' "GPS". The accuracy of "Beidou" in the Asia-Pacific region reaches 10 centimeters, far surpassing the 30 centimeters in the United States.

China no longer has to be constrained by the United States’ GPS
