seems like there are enough progress being made in the launcher platforms. We need more launch site & capacity coming up as fast as possible.

LandSpace has delivered the first TQ-15A engine for the second stage of the improved Zhuque-2 rocket. TQ-15A will replace the TQ-11 and TQ-12 previously used in the second stage of Zhuque-2.

TQ-15A increases vacuum thrust by 11.8%, vacuum specific impulse by 126m/s, and has a 60%~100% thrust adjustment range, and it can be started multiple times.

TQ-15A is part of the A-family of engines that also includes TQ-12A, which improves on the TQ-12 by increasing thrust by 9% and specific impulse by 40m/s, while achieving a weight reduction of 100kg.

With the delivery of TQ-15A, the improved Zhuque-2 rocket will now enter the final assembly stage ahead of its first launch in the second half of 2024.

Here's the LandSpace TQ-15A vacuum engine operating in space. TQ-15A has replaced the TQ-11 and TQ-12 previously used in the second stage of Zhuque-2.

(微分宇航) produces various payload mounting components and satellite chassis. The image below shows two of Weifen's designs for packing satellites onto a Long March 7.

The Guangchuan 01 and 02 satellites launched by ZQ-2E were attached to the rocket using the DXSF-SM24 C01~03 release mechanism made by Weifen Aerospace. It's specifically designed for holding and releasing stacked satellites.

The next generation Beidou satellite navigation constellation will be completed around 2035. The development of key technologies will be finished in 2025, and three test satellites will be launched around 2027. The first satellites of the constellation will be launched beginning in 2029, and the constellation will be finished in 2035.

11月28日上午，中国卫星导航系统管理办公室在京组织召开纪念北斗卫星导航系统工程建设三十周年座谈会。座谈会上发布了《北斗卫星导航系统2035年前发展规划》。未来在确保北斗三号系统稳定运行基础上，中国将建设技术更先进、功能更强大、服务更优质的下一代北斗系统。按照计划，2025年完成下一代北斗系统关键技术攻关；2027年左右发射3颗先导试验卫星，开展下一代新技术体制试验；2029年左右开始发射下一代北斗系统组网卫星，2035年完成下一代北斗系统建设。

On the morning of November 28, the China Satellite Navigation System Management Office organized a symposium in Beijing to commemorate the 30th anniversary of the construction of the Beidou Satellite Navigation System. The "Beidou Satellite Navigation System Development Plan before 2035" was released at the symposium. In the future, on the basis of ensuring the stable operation of the Beidou-3 system, China will build a next-generation Beidou system with more advanced technology, more powerful functions and better services. According to the plan, the key technologies of the next-generation Beidou system will be tackled by 2025; three pilot test satellites will be launched around 2027 to carry out the next-generation new technology system test; the next-generation Beidou system networking satellites will be launched around 2029, and the construction of the next-generation Beidou system will be completed in 2035.

The carbon-fiber composite payload fairing for Tialong-3 has been delivered. The fairing is developed by Tianjin iStar. It's 4.2m in diameter and 13m long.

More on Tianjin iStar's product lineup. The company specializes in carbon fiber composite parts that include rocket payload fairings (image 1, 2) and rocket fuselage sections (image 3, 4). The company also produces wings for UAVs such as the FP-985 unmanned drone (image 5, 6). Other aerospace products include composite landing gear assembly and fuel tanks. The company also produces flexible solar panels up to 50 square meters in area for space applications.

Manned moon landing project! Rocket launch tower

Wuchang Shipbuilding recently signed the contract to build the CZ-10 mobile launch tower. The company is experienced in constructing space launch facilities at XSLC, JSLC and WSLS since the 1990s..

The rocket active launch tower is an important structure of the active launch platform, also known as the "umbilical cord tower". It is the key equipment for the implementation of the "three vertical" program in manned space engineering, and has an extremely important impact on the launch of spacecraft. The tower has propellant delivery pipes, power supply cables and cables for wired detection. The space launch site maintains the final connection of cables and pipelines between ground equipment and rockets through umbilical towers, supplies power, gas and fuel to rockets, and sends wired detection signals from rockets and spacecraft to ground detection and launch control equipment. When the rocket is launched, the cables and pipelines connecting the umbilical tower to the rocket and the spacecraft are automatically disconnected, and the rocket ignites and takes off.
