【中国团队问鼎“航天奥林匹克”竞赛】
日前，第十一届国际空间轨道设计大赛落下帷幕，清华大学航天航空学院与上海卫星工程研究所联队摘得桂冠。本届大赛题目以“建造太空发电站”为背景，任务是在20年内发射10艘航天器连续探测、捕获太阳系小行星，建造12个围绕太阳环状分布的发电站。各参赛队需自行设计航天器轨道，使之尽可能多地探测、捕获小行星，提高发电站质量并减小其和太阳的距离，从而获得最大的资源利用效率。赛题涉及深空探测、小行星捕获、空间站建造等热门领域和前沿技术，探究了未来深空探测技术的发展和太空资源的利用问题，具有广阔的工程应用前景。
此次夺冠团队由宝音教授领衔的清华大学航天动力学实验室和上海卫星工程研究所的相关人员组成。团队对8万多颗小行星进行优化筛选，使用人工智能遗传算法解决轨道设计难题，给出了建造发电站的最佳方案，最终以明显优势领先第二名欧洲空间局联队夺冠。
本届大赛共吸引了来自美国国家航空航天局、欧洲空间局、法国泰雷兹空间公司、美国德克萨斯大学奥斯汀分校等全球顶尖航天机构的94个团队参与，参赛队伍数量为历届之最，获得竞赛第2至第6名的均为欧美强队。

[Chinese team aspires to the "Aerospace Olympiad" competition]

A few days ago, the 11th Global Trajectory Optimisation Competition came to an end, and the joint team of the School of Aeronautics and Astronautics of Tsinghua University and the Shanghai Institute of Satellite Engineering won the championship. The topic of this competition is "Building Space Power Stations" as the background.

The mission is to launch 10 spacecraft to continuously detect and capture asteroids in the solar system within 20 years, and build 12 power stations distributed around the sun. All participating teams need to design their own spacecraft orbits so that they can detect and capture as many asteroids as possible, improve the quality of the power station and reduce the distance between it and the sun, so as to obtain maximum resource utilization efficiency. The competition questions involve hot fields and cutting-edge technologies such as deep space exploration, asteroid capture, and space station construction. It explores the development of deep space exploration technology and the utilization of space resources in the future, and has broad engineering application prospects.

The winning team was composed of relevant personnel from the Aerospace Dynamics Laboratory of Tsinghua University and the Shanghai Institute of Satellite Engineering, led by Professor Baoyin. The team optimized and selected more than 80,000 asteroids, used artificial intelligence genetic algorithms to solve the orbit design problems, and gave the best plan for building a power station. In the end, it took a clear advantage to lead the second European Space Agency team to win the championship.

This competition attracted 94 teams from the world’s top aerospace agencies such as NASA, the European Space Agency, Thales Space, and the University of Texas at Austin. The number of participating teams is the largest ever. , The 2nd to 6th places in the competition are all strong teams from Europe and the United States.

10times more efficient and affordable than reusable first stage rocket idea brag by some.

Sure if that little thing can then carry:

Falcon 9: 22 metric tons to LEO
Falcon Heavy: 63 metric tons to LEO
Starship v1: 95 metric tons to LEO

But I'm pretty sure it's not going to scale well.

LOL... Elon Musk brag it cost only USD 25 million to send a man to ISS?

Tengyun probably cost only USD 500,000 to send a man to Chinese space station or even ISS.

Are you sure they are going to put people in that thing?
Are they going to jump out to get in the station?

["Yunlong" engine pre-cooler completed the first domestic Ma5 high temperature and thermal test assessment]

According to today’s news from the 31st Institute of the Third Academy of CASIC: Recently, the pre-cooling power technology center of the Institute completed the first "Yunlong" engine pre-cooler Ma5 thermal test at a test bed in Yungang, Beijing. Achieved temperature drop of nearly 1000℃ in milliseconds, the test achieves the desired goal. This test is the first Ma5 large temperature drop heat transfer test of the pre-cooler in China, which fully verified the rapid cooling ability of the pre-cooler, and the maximum flow rate, maximum temperature, maximum temperature drop and other indicators have reached the domestic leading and international advanced level.

The "Yunlong" engine is a multi-cycle deep-coupled pre-cooling engine based on liquid hydrogen fuel (ICE engine in English) proposed by 31st Institute for China's future reusable single-stage/two-stage orbiting vehicles and aerospace vehicles.

After years of hard work, the team has successively solved key technologies such as design, process, assembly, and testing, and successfully developed the largest-scale precooler prototype in China. The success of this test marked a milestone in the technological research of 31st Institute's Yunlong engines.

I got tagged into this thread by one of your girlie nationalistic pom pom friends so don't get your own pink panties in a bunch thinking I was just passing through on my own. You guys just keep on shaking it and hollering like a desperate streetgal on the corner perpetually looking for attention and a few dollars.
