Today, China's Taiyuan Satellite Launch Center used the Gravity-1 Yao-1 commercial carrier rocket in the waters near Haiyang, Shandong Province, to successfully launch the three satellites of Yunyao-18 and 20 satellites into the predetermined orbit, and the flight test mission was a complete success.
In China's aerospace field, Oriental Space Technology (Shandong)** is leading a revolution. The company's self-developed Gravity 1 rocket, with its unique configuration and powerful carrying capacity, is changing people's perception of Chinese rockets.
The Gravity-1 rocket is a semi-configuration medium-sized launch vehicle, 30 meters high, with a core stage diameter and a booster diameter of 265 meters. This design allows the rocket to be flexible and adaptable while maintaining a strong carrying capacity. The take-off weight of the rocket is 405 tons, the take-off thrust is up to 600 tons, and the carrying capacity in low-earth orbit is 65 tons, while the carrying capacity of 500 km in a sun-synchronous orbit is 42 tons. Such data is enough for Gravity-1 to occupy a place in the international rocket market.
What is more striking is that the powerful carrying capacity of the Gravity-1 rocket enables it to meet the needs of batch networking launch of medium and low orbit satellites and rapid response launch of medium and large space payloads. Yao Song, co-chief executive officer (CEO) of Dongfang Space, pointed out that most of the individual satellites of mainstream satellite constellations weigh between 200 and 300 kilograms. The carrying capacity of the Gravity-1 rocket of more than 4 tons enables it to realize batch launches with half or one orbit arranged at a time, which greatly improves the efficiency of networking.
Not only that, the Gravity-1 rocket can also support 100-kilogram satellites to achieve "one arrow and 30 satellites", and realize the launch mode of "one arrow and one orbit" or "one arrow and half orbit", helping the efficient advancement of constellation networking. For small cargo spacecraft and very large satellites weighing 3 to 4 tons, the Gravity-1 rocket is also up to the task. This diversified launch capability has undoubtedly won it a huge competitive advantage in the future commercial launch market.
What's more worth mentioning is that the Gravity-1 rocket is the first civilian and commercial rocket in China. This design makes it possible to achieve the carrying capacity of a medium-sized rocket with the "height" of a small rocket. This innovative configuration not only improves the carrying capacity of the rocket, but more importantly, it adapts to the needs of sea launches. In this way, China has achieved a mobile launch of medium-sized launch vehicles, which has further improved China's level and capabilities in sea launch technology.
In short, the emergence of the Gravity-1 rocket has undoubtedly injected new vitality into China's space industry. It not only demonstrates China's strength and innovation ability in the field of space technology, but also brings new possibilities to the global space launch market. In the future, we look forward to seeing more Chinese rockets like Gravity-1 leading the new trend of space science and technology.
