The history of the development of the Dragon spaceship, the important influence of the Dragon spacec

Dragon is also known as "Draco" spaceship。The name of the "Dragon" spacecraft comes from the American folk song "Dragon Puff". Led by SpaceX, one of the world's leading commercial spacecraft, the Dragon spacecraft is one of the world's first spacecraft developed by a private company.

The first-generation Cargo Dragon spacecraft successfully flew on December 8, 2010On May 22, 2012, it was successfully launched, on October 7, 2012, it was launched, and the cargo weighing 455 kilograms was delivered to the International Space Station for the first time, and on March 3, 2013, after successfully eliminating the thruster failure, the "Dragon" spacecraft of the American SpaceX company docked with the International Space Station.

The second generation of the Crew Dragon spacecraft is under development, which is expected to be manned to the International Space Station in 2017. At 2:49 on March 2, 2019, the manned Dragon spacecraft lifted off from the 39A launch pad of the Kennedy Space Center in Florida on a Falcon 9 rocket, and about 11 minutes later, the spacecraft successfully separated from the rocket and continued to fly to the International Space Station.

At around 5:50 local time on April 23, 2021, spaceX with 4 astronauts on boardThe Dragon spacecraft was launched from the Kennedy Space Center, the spacecraft will fly to the ISS.

Policy Background for R&D:

Since the retirement of the U.S. Space Shuttle in 2011, the United States has relied on Russia to transport people and cargo to the ISS. To change that, NASA is encouraging the private sector to develop "space buses" to and from the space station and the ground, a project that companies such as SpaceX are competing.

After Obama took office in the United States in 2009, he decided to encourage American private enterprises to enter the space market and promote the commercialization of space activities, hoping that space flight would be transformed from ** control to commercial operation.

At the behest of the White House, the National Aeronautics and Space Administration (NASA) has stepped up its support for private space companies. The Denon spacecraft is backed by NASA, which has also signed a $1.6 billion contract with SpaceX, which will carry out at least 12 unmanned missions for NASA and deliver supplies to the space station.

Since the beginning of human exploration of space, ** has dominated almost all space activities. As for the launch of the "Dragon" spacecraft, many foreign media described it as "opening a new era". Since the beginning of human exploration of space, almost all space activities have been dominated by ** until May 22, 2012.

The spacecraft docked to the International Space Station, making SpaceX the fourth entity after the United States, the European Union and Japan to dock with the ISS.

Expert commentary. On March 3, 2013, a Chinese space expert said that the Dragon spacecraft developed by a private American company is in a simpler state than China's Shenzhou spacecraft and Russia's Soyuz spacecraft. The Dragon spacecraft is actually just a cargo spacecraft, which is not equipped with a life support system and cannot carry astronauts like the Chinese Shenzhou.

In addition, from the point of view of maturity, the configuration of the "Falcon 9" rocket and the "Dragon" spacecraft is still inferior to the combination of China's "Long March-2F" and "Shenzhou". The latter has been verified by several successful launches. And the launches of "Falcon 9" and "Dragon" stumbled several times, and problems continued.

In addition, the "Dragon" spacecraft is one size smaller than China's "Shenzhou".

The "Dragon" spacecraft (Dragon) is also translated as "Dragon" spacecraft. The name of the "Dragon" spacecraft comes from the American folk song "Dragon Puff". The "Tianlong" spacecraft was developed by the space private enterprise - SpaceX of the United States, and adopted a seven-seater and wide cargo compartment design, "about one meter high and about one meter in diameter."

It is currently one of the world's leading commercial spacecraft and the world's first spacecraft developed by a private company. On December 8, 2010, the test flight of the Tianlong spacecraft was successful; On May 22, 2012, Tianlong was successfully launched; On October 7, 2012, the Denyu spacecraft was launched, delivering the first cargo weighing 455 kilograms to the International Space Station. On March 3, 2013, after successfully troubleshooting the thrusters, the Dragon spacecraft of the American company SpaceX docked with the International Space Station.

Dragon is also known as "Draco" spaceshipThe name of the "Dragon" spacecraft comes from the American folk song "Dragon Puff". Led by SpaceX, one of the world's leading commercial spacecraft, the Dragon spacecraft is one of the world's first spacecraft developed by a private company.

At 3:22 p.m. EST on May 30, 2020, NASA's commercial manned aviation program successfully launched its first manned trial. On August 2, the American Dragon spacecraft returned to Earth with two astronauts on board.

SpaceX Musk has revealed some highlights of the long-awaited second-generation Dragon spacecraft. "It has a propulsion system mounted on the side and large portholes for astronauts to look out, and a landing bracket at the bottom that can be ejected, which looks like an alien spaceship," he said.

Musco wanted the spacecraft to land instead of on the surface. And the Dragon spacecraft is able to land on the water. SpaceX has already conducted landing tests with its Grasshopper rocket, and several test flights have been higher than the last, but each test has not been aimed at reaching space.

Musk added that the Dragon spacecraft is not the only target for the company to upgrade, and that the Falcon 9 rocket will also be restructured to increase capacity by 60%-70% and increase the power of the thrusters by 60%.

SpaceX's most recent Dragon spacecraft mission ended after three weeks of connection to the space station and landed in the Pacific Ocean with about 1,211 kilograms of scientific facilities. SpaceX has a $1.6 billion deal with NASA that requires 12 cargo missions. NASA also has a $1.9 billion commercial supply contract with Orbital Technologies and at least eight unmanned cargo shipments.

Orbital Technologies will launch a test flight of the rocket in mid-April.

The retirement of the U.S. spacecraft in 2011 led the space agency to rely on Russia's Soyuz to carry astronauts to and from the space station. Once private space flights become viable, NASA hopes to use them to carry astronauts to the International Space Station. SpaceX is one of four companies competing for NASA's contract to carry astronauts.

SpaceX's manned spacecraft is capable of carrying seven astronauts to low-Earth orbit, and the company is planning to further develop a manned capsule by the end of this year.
