Four stars with one stone! China's gold medal rocket has been successful again: 31 years of ultra-high reliability

The four satellites of Hongtu-01 are all synthetic aperture radar (SAR) satellites, which are used for remote sensing observation and application.

This launch is the 469th launch of the long March series of carrier rockets.

The long March II rocket used for this launch is known as the gold rocket.The project was established in 1990 and flew for the first time on August 9, 1992. Over the past 31 years, the success rate of launch is extremely high, and the reliability index is 0.97, which is one of the best in the world.

In the past 2022, China has launched a total of 64 space launches and 2 failures.In the past 2022, China has launched a total of 64 space launches and 2 failures.

The Chang Erding carrier rocket has the largest carrying capacity among the single-stage carrier rockets in China, with a take-off thrust of 300 tons and a capacity of 1.2 tons corresponding to 700 km of solar synchronous circular orbits. it has the characteristics of high reliability, high safety, low cost, short period and so on.

It can be combined with the upper level of the Expedition series to provide multi-satellite out-of-orbit network deployment and launch, greatly increasing the carrying capacity above the orbital altitude of 1000 km.
