What is the reason for the failure of a private commercial launch vehicle in Jiuquan?

The yearning for deep blue explains the rational exploration and magnificent romance of human beings as a group. The pursuit of space not only gave birth to countless magnificent poems, but also brought hard-core technology and commercial map, which gave birth to a thriving commercial aerospace industry. Stars splash Evian, dew is about to drip, and Ailan cuts treasures. The blue sky is like practice, and the light shakes the Beidou. At the same time, there has also been an upsurge of private commercial space flight in China. Many start-ups in China's aerospace industry have made huge financing in this cycle and achieved technological breakthroughs.

Ceres-1 launch vehicle is a four-stage small commercial launch vehicle independently developed by Xinghe Power Aerospace. Committed to providing customized launch services with high quality and low price for commercial microsatellites. The first, second and third stages of the rocket adopt solid motors, and the fourth stage is the liquid upper stage. The diameter of the rocket is 1.4m, the total length is 20m, the take-off weight is 33t, and the carrying capacity of 500km sun-synchronous orbit is 300kg. It is the most cost-effective and competitive small launch vehicle in the current commercial launch market.

This mission is the second flight of Ceres-1 carrier rocket, which has achieved the first continuous success of private rockets in China and the first breakthrough of multi-satellite commercial launch with one arrow. On June 7, 2020, 165438+ Ceres- 1, a launch vehicle independently developed by Xinghe Power, successfully made its first flight, putting the "Apocalypse Eleven Stars" into the scheduled orbit. This is the first time that a private commercial rocket in China has entered a 500-kilometer sun-synchronous orbit.

When the launch vehicle was launched, the first and second stages were very smooth. During the third stage ignition, one of the engines failed, resulting in unstable attitude. The flight altitude began to decrease from about 200km, and the final speed was only 7. 1km/s, so it was impossible to enter the orbit. The specific cause of the failure may be unsuccessful secondary ignition or premature shutdown. If the problem is not serious, the satellite can be forced into orbit by its own maneuverability as in 2009, but at the cost of a much shorter life, but this time the problem is obviously not small, because both the rocket and the satellite were directly blown up.
