At 14:50 on December 27, 2023, the "Kuaizhou-1A" Yao-27 carrier rocket carrying 4 satellites of the "Tianmu-1" constellation 19 22 satellites was ignited and launched from the 95A station of the Jiuquan Satellite Launch Center, successfully sending the satellite into a sun-synchronous orbit.
The payload of this mission is the "Tianmu-1" meteorological constellation 19 satellites ("Xiyong Microelectric Park No. 3 satellite (Gui'an 01 star (Gui'an 02 star is the Beidou GNSS (Global Navigation Satellite System) remote sensing detection satellite developed by Shenzhen Rubik's Cube Satellite Technology, which is the fifth batch of networking satellites of the constellation, which is mainly used to obtain information on environmental elements such as the global ionosphere, sea surface wind field and thermosphere atmosphere, and realize the three-dimensional and integrated detection of the global all-weather ocean, atmosphere and ionosphere.
The Tianmu-1 meteorological constellation aims to achieve high-quality global meteorological data acquisition and promote the development of the national economy empowered by spatial information technology. So far, the number of satellites in orbit of the constellation has reached 18 through five batches of launches.
Kuaizhou-1A is a small four-stage carrier rocket launched by aerospace science and industry rocket technology, with the first and second stages being solid stages and the fourth stage being liquid stages. This type of rocket is about 20 meters long and has a maximum diameter of 14 meters, optional diameter 12m 1The 4-meter fairing has a take-off mass of about 30 tons and a take-off thrust of 60 tons, and its 500-kilometer sun-synchronous orbit (SSO) capacity is 250 kg, and its 700-kilometer sun-synchronous orbit (SSO) capacity is 200 kg.
Since the successful launch of the "Kuaizhou-1A" Yao-23 rocket on June 22, 2022, the rocket has won 10 consecutive victories, creating a new winning streak for the rocket. Since its successful maiden flight, the Kuaizhou-1A rocket has carried out a total of 24 launches, of which 22 have been successful and 2 have failed, with a success rate of about 92%.
This launch is the sixth launch of the Kuaizhou-1A rocket this year, the 35th launch of the Jiuquan Satellite Launch Center, the 66th launch of China, and the 216th launch of the world. The launch is only two days after the last launch of the Kuaizhou-1A rocket, which is entering a high-density launch period. As of this launch, the total number of space launches in China this year has reached a new high, with the highest record in previous years being 64 in 2022.
