At 3:22 p.m. Eastern Time (3:55 p.m. Beijing time May 31), SpaceX's new "Dragon" crew spacecraft was successfully launched from the Kennedy Space Center in the United States via a Falcon 9 rocket, bound for the International Space Station.


This successful launch heralds the arrival of the era of global commercial manned spaceflight. SpaceX officially became the first private company to master the ability to build and launch manned spacecraft.

Musk's interstellar kingdom has finally lit its first star, and the space dreamer has drawn a trajectory of The Times, opening a new era of human spaceflight. The successful launch greatly stimulated the development vitality of the commercial space market.


In the near future, new commercial space models such as satellite Internet, space tourism, commercial crew, and the development of space system products based on commercial components will be further improved, and the related industry chain, such as the space parts processing market will also have new machines. Below with Xiaobian to dig a dig!


Dapeng will see great potential in | commercial space market


Commercial space includes two important sectors: the commercial space infrastructure and support industry, and the commercial space products and services industry.


Commercial space infrastructure and support industries mainly include: satellite manufacturing, rocket launch services, space stations, ground launch bases and related equipment. Among them, satellite manufacturing and rocket launch services accounted for more than 60%;


The commercial space products and services industry mainly includes: satellite television, satellite communications, earth exploration, etc., of which satellite television accounts for more than three-quarters of the sector.


Among them, you may not expect is that the profitable sector is the satellite service industry and ground equipment manufacturing, accounting for 45.13% of the revenue.

"Satellite Internet" is included in the scope of "new infrastructure". On the one hand, it shows the rapid development of commercial space technology, but also shows that the country attaches great importance to space development and the integration of heaven and earth information network. The construction of satellite Internet will bring new development opportunities to the rocket and satellite manufacturing industry, and also open up sufficient market space for domestic commercial space companies.

Since 2015, domestic investment institutions have gradually paid attention to the commercial space circuit.


Compared with SpaceX, which was established in 2002, most of the domestic commercial rocket companies were founded in 2015 and 2016. Since 2015, China has given birth to commercial rocket enterprises represented by Interstellar Honor, Blue Arrow Space, Xinghe Power, Science and Technology rockets, Long March rockets, and commercial satellite enterprises represented by Micro and Nano Starry Sky, Galaxy Space, and Tianyi Research Institute.

China's commercial space started late and is still in the stage of catching up. The state has also issued policies to support industrial development. In April 2019, the National Space Law was included in the legislative plan of the Standing Committee of the 13th National People's Congress, which will include the development of commercial space. The entire aerospace engineering industry is an industry with huge potential, from rockets, satellites, to closed-loop manufacturing of spacecraft, are inseparable from basic industrial manufacturing, and each part is related to the result. Whether the quality and cost of parts can be controlled will be the opportunity for processing and manufacturing in the future.


Vertical | processing and manufacturing difficulties have been solved


The structure of aerospace products mainly includes the main engine (or bomb body, arrow body, star), engine, aircraft (bomb, arrow, star) equipment or components.


Structural features: The shape structure is complex, and there are many holes, holes, grooves, reinforcement links, etc., and the processing precision is high.


The processing requirements of aerospace products are high, and new materials, new structures and new technologies are emerging endlessly. A large number of new materials such as aluminum alloy, titanium alloy, high-temperature alloy, high-strength steel and composite materials are used. Most of the above parts need to go through the cutting process, CNC machining technology and CNC machining equipment has become one of the main needs in aerospace product manufacturing.
