银河航天 Galaxy Space – is located 3rd Floor, Building B, Baosheng Plaza, No. 8 Heiquan Road, Haidian District, Beijing, China, People’s Republic of China… Galaxy space- Aerospace is One of China, People’s Republic of China’s leading satellite Internet solution provider and satellite manufacturer, and the first unicorn company in my country’s commercial aerospace field. The company is committed to independent research and development and low-cost mass production of communication payloads, core single machines, and satellite platforms. It has built internationally leading supporting development capabilities for communication payloads, core single machines, and solar wings in Xi’an, Chengdu, and Beijing, and is also building in Nantong. The new generation of satellite intelligent manufacturing factories has achieved mass production capabilities of hundreds of satellites.
【”Space Carpet”! Galaxy Aerospace] According to Xu Ming, founder, chairman and CEO of Galaxy Space , the new generation of communication satellites being developed by Galaxy Aerospace looks like a “space flying carpet”, with both The communication antenna also has a solar chip that can convert solar energy into satellite energy. It is a communication satellite that integrates a phased array antenna and a solar wing. The key technology is called “wing array integration”.
The antenna is the core part of the satellite communication system and a key factor in determining the quality of signal transmission. Using large antennas can increase the gain of signal reception and transmission, thereby improving communication quality. The “wing array integrated” satellite can have a large antenna area and a powerful energy system, which can make the satellite more powerful when transmitting signals. It will be used to support the broadband communication needs of future mobile phones directly connected to satellites.
At present, Galaxy Aerospace has completed key technical research on the two-dimensional deployment of the “Wing Array Integrated” satellite. Generally speaking, the satellite’s antenna or solar wing generally only expands in one direction (such as horizontally) when unfolded. The so-called two-dimensional expansion means that the satellite’s antenna and solar wing must be deployed in an orderly manner in both the horizontal and vertical directions. . In view of this configuration in which the size of the satellite platform and the phased array are reversed, the traditional satellite-arrow connection, compression and separation technology cannot be used. The technical team designed and completed an integrated release plan; for extremely large-area arrays, high deployment accuracy and deployment stiffness are required In order to meet the large requirements, the technical team has broken through technical challenges such as folding and compaction, two-dimensional orderly deployment in orbit, and slowing down the impact of deployment, and completed the development of key mechanisms suitable for the deployment of satellite giant antennas and solar wing integrated arrays, and will Continue to carry out research on key technologies such as wing array integrated efficient heat dissipation and distributed power supply.
Facing the future, Galaxy Aerospace will accelerate the research on key core technologies such as phased array antennas, on-board large energy sources, and digital processing loads, and work with the upstream and downstream of the industrial chain to tackle key problems to help the development of my country’s aerospace information industry and the construction of a powerful aerospace nation.

The latest news from Galaxy Power – Ceres 1 will return to flight in two months – Progress of Pallas 1 Onwards
October 29, 2023, at the Beihang Alumni Innovation Forum held during the 71st anniversary of Beihang University, Galaxy Power CEO Liu Baiqi, who is a Beihang alumnus He delivered a speech titled “Building a New Generation of Low-Cost, Highly Reliable Commercial Launch Vehicles” and introduced the development of Galaxy Power. Among the more important new information are: 🚀 Ceres 1 has a low-orbit carrying capacity of 300 kilograms and sells for 4.5 million
. Around US$7 million, compared to US$7 million for 150 kilograms of electronic numbers.
🚀 Ceres 1 has been put into production for 30 rounds (!) 🚀 Ceres 1 is expected to return to flight in two months, with the mission of Remote Nine, codenamed “We won’t stop” 🚀 Some people think that Ceres 1 has been fired too intensively. It is necessary to slow down, but Liu Baiqi insists that there is no room for reuse of small rockets. The only way to achieve commercial success is large-scale industrial production, and high-density launches must continue to be promoted. 🚀 Ceres 1 will have two more launches by the end of this year. The future goal is 40 launches per year, which is equivalent to rockets hitting the sky every week.
🚀 The future development direction of medium and large liquid rockets must be reusable. 🚀 Pallas 1 uses seven engines in the first stage, which are reusable to achieve power redundancy and can complete the launch even if one engine fails. 🚀 Pallas 1 is currently aiming for its first flight in the second half of 2024. The recyclable first-level Pallas 1A will make its first flight in 2025, and the CBC configuration Pallas 1B will make its first flight in 2026. 🚀 The Pallas No. 1 that was “off the assembly line” reported by the media was actually a joint training test arrow. 🚀 There are also complete speech videos and transcripts of Galaxy Power’s Anhui engine production base, vertical take-off and landing verification, sky liquid oxygen kerosene engine test, etc. See: Highlights of the 2nd Beihang Alumni Innovation Forum | Galaxy Power Aerospace Founder & CEO Liu Baiqi

“Dear leaders, teachers, and alumni, good afternoon! I am very honored to be invited to participate in the second Beihang Alumni Innovation Forum. Every time I come back to school, I feel like I am going home. It feels very cordial. I came to Beihang University to study for a PhD in 2003. I graduated in Department 17 and enrolled in Department 15. After graduation, I stayed in Department 17 and worked there for three and a half years. In 2011, I was assigned to the China Launch Vehicle Research Institute. I found that many of my colleagues and leaders around me were alumni of Beihang University, and they were no strangers to them after I arrived there. In 2018, I left the First Institute of Aerospace Engineering and founded a private company. At that time, I wanted to start a business. I wanted to build rockets but had no money. So I got the first angel funding. He is also an alumnus of Beihang University. Of course, the backbone of core technologies are Beihang alumni, so the genes of Beihang are engraved in my bones, and the strength of Beihang has always been with me as I grew up.
The title of today’s report is “Building a new generation of low-cost, highly reliable commercial launch vehicles.” What is a rocket company’s business model? Making rockets has corresponding courses and techniques for Beihang people, but for commercialization, the business model of making rockets is to independently develop and manufacture a rocket, use it as a means of transportation, and use it to put satellites into orbit. , charging a fee for launch services. You can understand that Rocket Company is essentially a courier company, and we actually deliver couriers.
We have also established a website where you can book our launch services. If you want to send something to the sky, you can contact us. Why come to us? Because in China’s private commercial aerospace field, Galaxy Power has created some technologies. We are the first private rocket company to put satellites into orbit. We are also the first private rocket company to implement sea launches. We are also the first private rocket company to achieve industrial mass production of rockets and the first private rocket company to implement high-density launches. In the field of private rockets, we have the most launches and the highest success rate. So it is worth having.
However, most people do not have the opportunity to launch satellites into the sky. Where is our market? Who will launch the satellite? What kind of customers do we face? The market we are facing is mainly low-orbit satellite Internet. In 2021, the National Development and Reform Commission included this as a new device. From an academic perspective, it has set off a craze for low-orbit satellite Internet. Tens of thousands of satellites may enter space in the next five to ten years. , these satellites are manufactured, launched and operated by themselves, and the data formation services will be an external market. With so many satellites wanting to enter space, rockets are the only channel for satellites to enter space. If all these satellites enter space, our country’s current transportation capacity will be less than one-tenth of this capacity. This is a huge gap in demand. This is one of the driving forces for the birth of Chinese private rocket companies and the birth of commercial rocket companies. The market needs rockets and transportation capacity. But don’t think this requires all rockets. For example, the Chinese car market is huge and they need cars, but some cars sell a million cars a year, and some cars only sell a few cars a year. So let’s analyze what kind of rockets are needed for such an upsurge in the development of low-orbit satellite Internet? What kind of rocket is needed to meet such market demand.
There are two trends in the development of low-orbit satellite Internet, one is large and the other is small. The trends are very obvious. The big trends refer to the big satellites and big constellations. For example, the United States and China launch tens of thousands of satellites into space. The mass of the satellites increases from 260 kilograms to 750 kilograms, and will increase to 1.2 tons in the future. This means that more than 10,000 tons of weight must be sent from the earth to orbit. Requires a lot of experience. It is impossible for us to send such a heavy weight to the sky one kilogram by one. We can only send a lot in batches at one time. At this time, medium and large liquid launch vehicles are needed. At the same time, traditional rockets are disposable and will be damaged after each launch. In order to reduce costs, we need to reuse rockets. For large satellites, we need large reusable liquid rockets. Few countries can complete the construction of such a giant constellation, and few people can build such a constellation.
Another trend is small satellites and small constellations. Everyone recognizes the trend of satellite miniaturization. In the past, satellites weighing several tons may now be able to achieve their functions with satellites weighing hundreds or even tens of kilograms. Building such a small satellite constellation with dozens or hundreds of stars can also solve narrow applications in various fields such as communications, joysticks, meteorology, etc. If there are dozens of stars, each of which only weighs tens of kilograms, and is distributed to There are several orbital planes, and each orbital plane only has a total weight of a few hundred to launch. At this time, if we still use a large rocket with a carrying capacity of more than ten tons or more than twenty tons to launch this satellite, it is equivalent to using an Airbus 380 to make a straight-line passenger plane. , that one must lose money. So for small satellites and small constellations, this small trend requires lightweight launch vehicles.
According to this market analysis, Galaxy Power only focuses on market demand. We have deployed two types of rockets: One is a lightweight launch vehicle called Ceres 1, which is deployed around small satellites and small constellations. Its carrying capacity is only a few hundred kilograms. , but it is as convenient as a taxi. Once the satellite comes, you can get in the car and go, and it can have a high frequency of transmission. The other is a medium-to-large reusable liquid launch vehicle, with a carrying capacity ranging from five tons to more than ten tons, and in the future it will reach a large-scale carrying capacity of more than thirty tons. When developing large-scale reusable liquid rockets, the development ideas of modularization and serialization were adopted. The rocket in the middle actually has a red line. The red line is the first stage of the rocket. Above the red line is the second stage. The first and second stages are made to have independent control systems, power systems, structural systems, and independent flight modes. The two are connected in series to form a low-orbit carrier. If its carrier capacity is not enough, two boosters can be added to the one-level parallel bundle to increase the carrier capacity to about 14 tons. In this way, the difficulty of rocket development is reduced, the development cycle is shortened, and the corresponding risks are reduced. For business, it is also very necessary for an enterprise to control corporate risks.
Let me introduce these two rockets to you: The first one is Ceres 1. It is a light and small launch vehicle with a diameter of only 1.4 meters. It has a low-orbit carrying capacity of 400 kilograms and can carry an orbit up to 300 kilograms. But this rocket is bragging. Beihang people are generally relatively low-key and pragmatic. At this time, based on the data, it is still bragging. It is the most cost-effective lightweight launch vehicle in the world. Before this, we all knew that the US Electron was Rocket Laboratory. The Electronic Number made by this company is the best small rocket in the world. It has launched more than 30 times. Its low-orbit carrying capacity is 150 kilograms and the price is 7 million US dollars. Ours is 300 kilograms and the price is 450. About ten thousand US dollars. In terms of cost performance, it is a complete victory over electronic rockets, so we say that China and the United States do not cooperate or compete in small rockets. If this competition can be opened up, we actually still have some advantages in the field of small rockets.
You may be curious and ask, why does our rocket have such a competitive advantage in the market since Galaxy Power was established in such a short time? It is because of the technological innovation spirit and innovative power of our Beihang people.
This rocket is called a four-star rocket. It has corresponding technological innovations in design, materials, processes, and experimental methods. Although there are many people in our company, most of the products produced by the aerospace institute in the past were mature launch vehicles. It is not that we have made a rocket from the past, but we have carefully analyzed the market demand ourselves. Market-oriented needs have been redefined to create such a rocket. There are many details of these technological innovations that have not been elaborated here.
For example, we used to call Beihang University laser rapid prototyping, but now it is called 3D printing. This is Beihang University’s advantageous technology. The engine here is the 4D engine of our rocket, which adopts the traditional manufacturing model. But what are the disadvantages? The cost is relatively high. Such a small engine is only about the size of a finger, costs 500,000 to 600,000 yuan, has a production cycle of 6 months, and is also very heavy. We transformed it into titanium alloy 3D printing, reducing its cost from 5 to 6 million yuan to 70,000 yuan. The production cycle was shortened from the past 6 months to one month and the weight was reduced by half. So we say that this is the power of innovation, and it is also the power of Beihang that we talked about in today’s forum.
At the same time, we have completed the launch of 10 rounds of Ceres 1, the first launch vehicle to achieve mass production. Any technological product, any equipment, or equipment must be industrialized and mass-produced in order to reduce its cost and achieve higher reliability. At present, this rocket is the first mass-produced rocket in China, and it is also the first domestic commercial launch vehicle to achieve high-density launch, because we have to launch it after we produce it. From July 22 to September 11 this year, we launched a rocket every 12 days. This is currently the highest launch frequency in China. This high launch frequency is like taking a high-speed train. There are more choices for customers. Provide better launch services.
At the same time, Ceres 1 is the first rocket that can be launched both from land and sea, and Galaxy Power is the only private rocket company. Sea launch has caused a relatively large impact at home and abroad. This launch is also a technology that has successfully launched Ceres 1 for nine consecutive times. Starting a business is a risky thing, and building rockets is also a risky thing. There is an analogy in making rockets: ten thousand people, one gun. If ten thousand people participate in building a rocket, what are the requirements for each person? Everyone is required to do things right the first time, and the work he does is required to have zero defects. If one person’s work is defective, it may bring fatal risks. When Ceres 1 was producing the tenth launch vehicle, when we were producing the supplier’s engine nozzle, due to improper drilling operations, internal defects and damage were caused to the nozzle, so in September 2021 When our Jiuquan Satellite Launch Center carried out its tenth launch mission on the 21st, it no longer had nine consecutive victories. The pause button was pressed during high-density launches. Many people sent messages to comfort and encourage. Many shareholders were also worried, and even many People don’t call me for fear of getting seriously hurt. As a Beihang person and an entrepreneur in the aerospace industry, we cannot be defeated by failure or any setback. This is number one.
When we failed the second time, we didn’t’t have time to think about this. We immediately obtained all the telemetry data of the flight time and all the external images, and analysed each frame of data and images, hoping to find the cause of the failure. We worked non-stop for 48 hours. , quickly located the fault that caused the rocket’s flight failure, and located the fault on the engine baffle. We formed a working group with the baffle supplier, completed the special review of Ceres 1 on October 23, and began preparations for flight. This was the shortest and fastest rocket flight failure in the history of aerospace. We also discussed and researched with our suppliers and raised issues to prevent similar things from happening again. We proposed a series of setbacks and methods for subsequent improvement of quality. At the same time, we not only made requirements for suppliers, but also proposed to Inner Galaxy Power to carry out a The quality improvement project will sort out our potential risks and weaknesses from the entire process of our design, production, assembly, testing, and launch, and propose targeted quality improvement measures. Through these measures, we will further improve the quality of Ceres 1. We hope that it will take two months Afterwards, test flights will be carried out, and I hope everyone will see a better Ceres 1.
I heard different voices. Some people with good intentions advised us whether we shot too much. If we shot one rocket every 12 days, if we shot a few less, we would not face such a failure. Look at it this way, there are big rockets and small rockets. For a small rocket like Ceres 1, first of all, we believe that it has its own segmented commercial market, so the demand for industrialization necessitates this. There is no need to reuse small rockets. Once reused, a lot of systems will be added, a lot of fuel will be reserved, and the carrying capacity will drop sharply. The only channel is industrialized large-scale production, which means high-speed launch. For this We will not change our direction and goals, and we will continue to promote high-density launches. We have completed 6 launches this year, and there will be two more by the end of the year. In the future, we hope to increase the frequency of Ceres-1 rockets to 40 launches per year, which is equivalent to rockets every week. At that time, we will be able to provide our satellite customers with better A more valuable launch.
For small rockets, it is necessary to implement large-scale industrial mass production. For liquid rockets, it is necessary to focus on commercial closed loop. The future development direction must be reusable. Galaxy Power has also laid out reusable medium and large launch vehicles. First of all, in order to make the rocket reusable, we designed a layout concept with seven engines in parallel. This can be reused and can also achieve power redundancy, allowing one Even if the engine fails, it can still fly normally. We have also developed a depth-variable thrust reusable liquid oxygen engine for the rocket, and have also conducted research on a vertical recovery algorithm. In terms of development direction, this rocket is aimed at being reusable, but in order to reduce risks, the first step is to put it into orbit and then recover it to increase the rocket’s carrying efficiency.
What you are looking at now is the engine production base built in Anhui. This engine was independently developed by us for this rocket. It also has a series of technological innovations. These are some large-scale support injectors with coaxial dual-core high-speed Filter pumps are innovative equipment in China. We have also completed the experimental verification of recycling. This is also the first time in China that the online optimization algorithm has been verified. This implementation is still very stable. Galaxy Power has built a 100-ton dual-station test bench around different production facilities for design, production, and experimentation. The first joint training test rocket has been assembled. We hope that through this launch vehicle, we will make greater contributions to the development of our country’s commercial aerospace industry. Contribution and strength of Beihang University.

Just now on the 2nd November 2023, my country China, People’s Republic of China has used an orbit-level engine for the first time to conduct a vertical take-off and landing test of a rocket, successfully conducting a key verification of rocket recovery and reuse.
At around 1400 Hours Hong Kong SAR- Beijing Time this afternoon 2nd November 2023, Beijing Interstellar Glory Space Technology Co., Ltd. successfully carried out the first vertical take-off and landing test of the Hyperbola-2 verification rocket at the Jiuquan Satellite Launch Center (official announcement: the first domestic use of full-scale reusable one-stage liquid oxygen Vertical take-off and landing flight test of methane liquid rocket).
The flight test mission of the liquid oxygen methane reusable verification rocket Hyperbola II (codenamed SQX-2Y) independently developed by Star Glory was a complete success
🔷The rocket adopts a full-size rocket body diameter of 3.35m and a total length of about 17m
🔷Assembled and independently developed by Star Glory The Focus-1 depth variable thrust liquid oxygen methane engine (codenamed JD-1) 🔷The test flight altitude is 178.42m, the flight time is 50.82s 🔷The landing position accuracy is about 1.68m, the landing speed is 0.025m/s, and the landing attitude angle is about 0.18°. The rolling angle is about 4°, and the flight test mission was successfully completed with high precision
The vertical takeoff and landing test is a key verification and iteration step for rocket recovery and reuse. The developers built a test platform with similar size, weight, power and control system to the first stage of the real rocket (or even directly modified it from the rocket body), and organized it in the atmosphere. Meters, hundreds of meters, and kilometers are gradually progressively tested (parts can be saved), thereby optimizing the software and hardware design, and finally realizing the recovery and reuse of the first stage of the rocket in orbit.
Today’s test rocket is equipped with a Focus-1 liquid oxygen methane engine. This is also the first time that my country has used an engine with the ability to enter orbit for such a test.
