1. Changerding launches 4 satellite Internet technology test stars<\/p>\n
Chang Er Ding\u2019s 97th launch<\/p>\n
At 12:00 on April 1, 2025, Beijing time, my country used the Long March-2D launch vehicle at the Jiuquan Satellite Launch Center to successfully launch four satellite Internet technology test satellites into predetermined orbits. The satellites launched this time were manufactured by Changguang Satellite (2 satellites) and Galaxy Aerospace (2 satellites). Satellites are mainly used for technical tests and verifications such as direct connection of mobile phones to satellites and integration of space and ground networks.<\/p>\n
Hello space:<\/p>\n
According to satcat information, four satellites were launched into a LEO orbit at an altitude of about 450 kilometers. Each satellite weighed about 300 kilograms. They were suspected to be StarNet second-generation verification satellites. Blue Star Optical Domain provides the laser communications payload for one of the satellites.<\/p>\n

2. Joint debugging of water spraying and noise reduction at Work Station No. 2 of Hainan Shangfa<\/p>\n
The flow rate of the whole system has reached a stable level of 120,000 tons per hour.<\/p>\n
Recently, the commissioning of the secondary water spray noise reduction system at Station 2 of the Hainan Commercial Space Launch Site designed and constructed by the Beijing Aerospace Experimental Technology Institute of the Sixth Academy of the Aerospace Science and Technology Group was successfully commissioned. It is expected to support more than 10 launch missions per year.<\/p>\n
Hello space:<\/p>\n
Hainan Shangfa No. 2 station is currently one of the few launch stations in my country that is compatible with the launch requirements of multiple types of commercial rockets. The flow rate of this water spray and noise reduction reaches 33 tons per second, which is equivalent to the 31 tons per second of Launch Site 39 of the Kennedy Space Center.<\/p>\n

3. The second factory of Gesi Aerospace is designed to produce 150 tons of satellites per year.<\/p>\n
The project plan review meeting was held in Jiuting Town<\/p>\n
The second factory of Gesi Aerospace is the core project of the commercial aerospace industry layout in Songjiang District. It is located in Jiufu Industrial Zone, Jiuting Town. It is planned to build a multi-story factory building and a basement equipment room with a total construction area of \u200b\u200bapproximately 36,000 square meters. The project mainly conducts mass production of ton-level satellites, with a designed production capacity of 150 satellites\/year, or 300 satellites below 500kg\/year.<\/p>\n
Hello space:<\/p>\n
As one of the core satellite suppliers of Qianfan, Gerth Aerospace will be responsible for half of the future 1,296 satellite production capacity of the Qianfan constellation. The construction of the second phase of the factory will be the key to whether the construction progress of the Qianfan constellation can be completed on schedule in the future.<\/p>\n

4. Hyperbola No. 3 completed the first-level methane tank hydraulic test<\/p>\n
One step closer to first flight<\/p>\n
On April 3, 2025, the hydraulic strength assessment test of the 4.2m diameter first-stage methane tank of the Hyperbola-3 launch vehicle independently developed and produced by Star Glory was successfully completed.<\/p>\n
During the test, the first-stage methane tank of the Hyperbola-3 launch vehicle was pressurized step by step, smoothly pressurized to the predetermined pressure, and finally kept at pressure for 15 minutes without any pressure drop. The product was in good condition and had no leakage, meeting the design specifications.<\/p>\n
Hello space:<\/p>\n
Hyperbola 3 plans to conduct its first flight + sea recovery test in Wenchang, Hainan at the end of this year. This first-level methane tank hydraulic test laid the foundation for the subsequent first flight.<\/p>\n

5. The Lijian-2 secondary power system test arrow enters the scene<\/p>\n
The second-stage rocket power test will be carried out at an appropriate time<\/p>\n
On April 3, the Lijian-2 secondary power system test arrow entered the Zhongke Aerospace Power Test Center in Aotou Town, Conghua District to carry out the trial commissioning and verification of the secondary power system. <\/p>\n
Hello space:<\/p>\n
Lijian-2 is currently scheduled to make its first flight in September 2025, carrying the China Space Station Canoe commercial cargo spacecraft. This second-level test run will be directly related to the progress of the mission.<\/p>\n

1. The first flight of the German Isar Spectrum rocket failed<\/p>\n
2025 First rocket flight in continental Europe except Russia<\/p>\n
It was reported on March 30 that the Spectrum rocket developed by a German private aerospace company was launched from the And\u00f8ya Space Center in Norway that day. It crashed and exploded after flying for about 30 seconds. This means that the first rocket launch on the European continent outside Russia ended in failure. Hello space: <\/p>\n
The rocket used for this test flight used a bi-component liquid rocket propellant of liquid oxygen + propane, which is said to be more “environmentally friendly” than methane. In addition, the founder of Isar claimed before the rocket was launched that it would only take 30 seconds to ignite the rocket successfully.<\/p>\n

2. SpaceX, ULA, and Blue Origin receive US$13.7 billion contract from the US military<\/p>\n
SpaceX wins $5.9 billion contract<\/p>\n
The U.S. Department of Defense recently awarded a $13.7 billion launch services contract to SpaceX, ULA, and Blue Origin to launch military and intelligence payloads. Among them, SpaceX received US$5.9 billion and is expected to carry out 28 launches, ULA received US$5.4 billion and is expected to carry out 19 launches, and Blue Origin received a US$2.4 billion contract and is expected to carry out 7 launches. Hello space: <\/p>\n
SpaceX currently has become the monopoly in the international launch market with the cost-effectiveness of Falcon 9. With the award of this launch contract, SpaceX has also become the biggest beneficiary.<\/p>\n

3. Canadian MDA acquires Israeli satellite chip manufacturer<\/p>\n
MDA acquired the company\u2019s satellite payload factory in 2023<\/p>\n
Canada’s MDA Space announced on April 1 that it plans to acquire Israeli satellite chip manufacturer SatixFy for US$269 million to further vertically integrate its constellation manufacturing capabilities. <\/p>\n
Hello space:<\/p>\n
Currently, MDA Space has received orders for 198 laser low-orbit communication satellites from Telesat and more than 50 direct-connect mobile phone satellite orders from GlobalStar. This acquisition is to enhance chip manufacturing capabilities to meet future constellation construction needs.

4. Chinese tycoon completes mankind\u2019s first polar orbit flight<\/p>\n
This flight was completed with an investment of US$200 million from Chinese tycoon Wang Chun.<\/p>\n
On March 31, SpaceX’s Dragon spacecraft launched four “civilian” astronauts into a 90-degree inclination orbit around the Earth’s poles for the first time, with a flight altitude of approximately 450 kilometers. This is the first time in human history that the North and South Poles have been crossed from above Earth orbit. <\/p>\n
Hello space:<\/p>\n
Chinese tycoon Wang Chun was born in Tianjin and is the co-founder of F2Pool. He made his fortune by investing in cryptocurrency and is currently a Maltese citizen.<\/p>\n
