A multi-star, a first-shot, how far is China Civil Aviation from SpaceX?

At 1300 hours on July 25, 2019, Beijing time, the Chinese private rocket company "StarCraft Glory" carrier rocket hyperbola No. 1 (SQX-1 Y1) successfully ignited at the Jiuquan Satellite Launch Center, and multiple satellites according to flight timing. And the payload is accurately fed into a predetermined 300 km circular orbit.

StarCraft Glory officially stated that the launch created the "three firsts" of China's commercial aerospace. That is, the first successful launch and high-precision orbit; the first multi-star launch into the orbit; the first space advertising and video back.

In fact, every industry needs iconic events to cause concern and bring substantial impact, as is the case in the commercial aerospace sector. Zhang Xiaomin, a special professor at the School of Aerospace Engineering at Beijing Institute of Technology, believes that the significance of this launch is that China's private commercial space launch vehicle truly has the ability to transport loads into space.

Prior to this, private rocket companies suffered two launch failures in succession. The first time was in October 2018, when the Blue Arrow Aerospace "Suzaku I" launch vehicle was launched in the 402 seconds after the launch, the third-level anomaly occurred, and the commercial satellite "Future" was not able to follow the planned schedule. The second time occurred in March this year, the OS-M launch vehicle launched in the zero-thousand space, after the first-level separation, the rocket attitude was unstable, and the launch mission was unsuccessful.

The case of rocket launch failure is not uncommon, but as long as one launch fails, it will cause heavy losses to the company's operations. In June 2015, the Falcon 9 launch vehicle exploded, leaving SpaceX operating losses.

Despite the development of rocket technology, the probability of successful launch is much higher than the probability of failure, but it is not just a rocket that fails, and its satellite and space loads are also destroyed. More importantly, a failure will cause the customer to doubt the reliability of the rocket and cancel all subsequent launch orders associated with the plan.

The aerospace industry has always been known for its high difficulty, high risk and high investment. And various factors make it more concerned than other industries. Once the launch fails, it will inevitably frustrate market confidence. Especially for commercial aerospace, the failure of the rocket will inevitably affect the enthusiasm of investors. Some people in the commercial aerospace industry have asserted that a large number of enterprises will be eliminated at the time of the rocket's entry.

The successful launch of the StarCraft Glory Launch Vehicle has rekindled the confidence of the people and investors in China's commercial spaceflight. On April 5, 2018, StarCraft Glory successfully launched the "Curve One" carrier rocket. Although it is a sub-orbital experimental rocket, there is no load, but this launch verified many key technologies.

It is understood that the newly launched hyperbolic No. 1 launch vehicle is the largest and most capable launch vehicle of China's private space flight: the three-stage series configuration of three solids and one liquid, with a total length of 20.8m and a total take-off mass of 31 tons. The 500 km SSO carrying capacity is 260 kg.

It seems that the acceleration of interstellar glory has made its launch vehicle more and more close to SpaceX.

Even so, the new expectations of China's commercial aerospace should not be limited to the "Chinese version of SpaceX." In fact, StarCraft is not willing to label this company. Huo Jia, vice president of StarCraft Glory, once said that the biggest gap between the company and SpaceX is "not a technology but a business atmosphere. It is only a matter of time to catch up with them."

One thing that cannot be ignored is that SpaceX's early experience is far more difficult than imagination. Before 2008, there were a few rocket launches, all of which failed without exception, so that SpaceX was long on the line of life and death and was on the verge of bankruptcy. Fortunately, NASA's $280 million financing was used for the upgrade of the Merlin engine and the development of the Falcon 9.

In addition to private capital, SpaceX has today's achievements and is inseparable from NASA. In the past ten years, NASA has provided space X directly or indirectly, including aerospace talents, technology transfer, and of course, banknotes.

The financing strength of China's private commercial aerospace is not lacking. Well-known funds including Jingwei, Huachuang, Gaochun, Chenxing, IDG, Shunwei, Source, Xianfeng, Mingshi, Fuxing, Saifu, etc. all have layouts on this track. Founded in October 2016, StarCraft Glory has exceeded 700 million in financing, and is the company with the highest cumulative financing in the commercial and aerospace sector.

In contrast to the United States, Musk was involved in commercial aerospace in 2002. Also born in the same period as SpaceX, there are companies such as Blue Origins that Bezos founded in 2000. Even emerging companies such as Oneweb have been established in China for three years before private commercial aerospace companies.

In addition, in terms of policy factors, the US Commercial Space Launch Act was passed by Congress in 1984. After the launch of the Launch Service Purchasing Act of 1990, the Commercial Remote Sensing Act of 1994, and the Commercial Space Act of 1998, capital boosts have led to entrepreneurial opportunities in various commercial aerospace applications in the United States. The support and development of China's commercial spaceflight was mainly due to the implementation of the 2015 military-civilian integration policy.

In summary, the Sino-US commercial aerospace competition, starting point is separated by more than 10 years. Compared with the most capable manned rockets in the world, the SpaceX Falcon heavy-duty launch vehicle has a full height of 70.01 meters, a core diameter of 3.66 meters, a take-off mass of 1420.788 tons, and a takeoff thrust equivalent to the sum of the thrust of 18 Boeing 747 passengers. The capacity of the low earth orbit carrier is 63.8 tons, and the launch vehicle of the Chinese private rocket enterprise has a long way to go.

Fortunately, as a means of transportation in space, Chinese private carrier rockets, which are expected by industry participants to have greater capacity and lower cost, are brewing.

Whether it is the strongest carrying capacity in history, or the vertical landing recovery, or Starlink integrated design of the Star and Arrow, and the Dragon Flying Ship Manned Plan. Most of the steps and plans of China's private rocket companies are the same as SpaceX.

StarCraft Glory announced plans for the next four years. The first is to make recyclable rockets a standard for Chinese commercial launch vehicles. It is expected to make the first flight reusable liquid launch vehicle in 2021 — — hyperbolic No. 2, the engine is a self-developed 15 ton liquid oxygen / methane variable thrust rocket engine & mdash; — focus one, currently The 200-second long-range test has been completed.

Then, the hyperbolic No. 3 liquid launch vehicle that first flew in 2023 used a 100-ton liquid oxygen/methane variable thrust rocket engine —— focus No. 2. As a result, StarCraft Glory will complete the construction of the carrier rocket spectrum from solid to liquid, from small to large.

The pace of StarCraft glory to open commercial operations is approaching. At present, it has mastered the core technology of the launch vehicle and system integration, solid and attitude control power, electrical synthesis, navigation guidance and control, test launch, final assembly test and core stand-alone software, and has complete the launch vehicle system engineering. The process, the development of all-factors and the ability to launch services, and the prototype of the commercial closed-loop are basically formed.

If the development is smooth, China's commercial spaceflight must be accelerating. According to the plan of StarCraft Glory, it is expected that by the end of 2020, StarCraft will complete the launch of the hyperbolic No.1 remote two to six launch vehicle launches, forming a large-scale solid-state launch vehicle. However, in the long-term, high-risk, heavy-asset hard-tech track of commercial aerospace, can this highly anticipated tomorrow's star become a representative of China's commercial space, and compete with SpaceX, there is still a relative A long way to go.
