Recently, the China Manned Space Engineering Office issued a notice on soliciting the overall plan for the low-cost cargo transportation system of space stations (hereinafter referred to as the "notice"). The announcement states that in order to further reduce the cost of transporting goods up the space station, enhance the flexibility of transporting goods up, and explore the development of commercial aerospace models, an announcement is now being issued to the whole society to solicit the overall plan for the low-cost cargo transportation system of the space station. The China Manned Space Engineering Office will organize and conduct the development and flight verification of low-cost cargo transportation systems based on the solicitation of proposals, market-oriented procurement of low-cost cargo transportation services, and ultimately build a safe, reliable, diverse, and cost-effective space station cargo transportation system. Improving quality, increasing efficiency, and reducing costs is one of the effective measures to promote the further development of the industry, and is no exception for aerospace cargo transportation. With the official completion of the Chinese space station and its entry into the stage of application and development, transporting goods, propellants, and other materials to the space station has become a normal work. On May 10th, the Long March 7 Yaoqi carrier rocket carrying the Tianzhou-6 cargo spacecraft successfully carried out the first launch mission of China's space station application and development phase. Unlike the previous Tianzhou series cargo spacecraft, Tianzhou VI has been upgraded and transformed, with an effective loading capacity expanded by 20%. The overall cargo capacity has increased from 6.9 tons to 7.4 tons. The purpose of doing so is to optimize the demand for cargo spacecraft launches from twice a year to three times a year by improving the cargo transportation capacity of the spacecraft, in order to reduce transportation costs. Therefore, this announcement solicits low-cost transportation plans, which can be said to be a further extension and expansion of the original intention of the relevant responsible departments for the upgrading and renovation of Tianzhou-6. From the perspective of the long-term development of the aerospace industry, the announcement solicits the overall plan for the low-cost cargo transportation system of the space station for the whole society, which is a very open attempt. Government procurement is a modern management method that saves financial expenditures and improves the efficiency of fund utilization. In the context of a market economy, government procurement can effectively stimulate market vitality and drive related industries to undergo self innovation and continuous iterative development. The continuous progress and development of technology cannot be separated from the new ideas and ideas that people burst out in benign competition and implement them, just like aerospace technology. As a leading aerospace country in the world, China entered the international commercial launch market as early as 1985, providing launch services to international users. The key to obtaining commercial launch service orders is to ensure the success rate of rocket launches, which to some extent forces the Chinese aerospace industry to continuously improve its research and development level, and to make corresponding improvements and research based on the different loads and mission characteristics of each international user. In the process of participating in the competition in the national commercial launch market, China's rocket adaptability has been improved, and rocket research and manufacturing technology has also made significant progress. The development of the aerospace industry cannot be separated from the improvement of marketization level. As a strong aerospace country, American commercial aerospace companies have undertaken the vast majority of space launch missions and have been proven to be safe and economical. Nowadays, Chinese commercial aerospace enterprises have sprung up like mushrooms after a rain, with multiple commercial aerospace enterprises having certain launch capabilities and sending payloads into space several times. this
