CAS Space, a leading commercial rocket maker in China, launched the 10th rocket in its Kinetica 1 series on Sunday morning, successfully putting two experimental satellites into their preset orbital positions.

The rocket lifted off at 11:32 am from the Jiuquan Satellite Launch Center in northwestern China's Gobi Desert and then placed the payloads — the Chutian 2A and 2B technology demonstration satellites — into orbit, the company said in a statement.

The satellites were developed by CASIC Space Engineering Development, a subsidiary of the China Aerospace Science and Industry Corp Second Academy in Beijing.

After entering orbit, they are tasked with verifying their Earth observation and hyper-resolution processing and application capabilities.

The data obtained by them will be used to facilitate the operation and maintenance of large water conservancy facilities, dynamic monitoring of marine ecological environments, and prediction, early warning, and assessment of natural disasters, further helping to improve China's capabilities in disaster prevention and relief and emergency management work.

To mark the opening of the 15th National Games, which will open on Sunday in Guangzhou, South China's Guangdong province, engineers painted the games' logo and some relevant slogans on the rocket's body.

The mission is China's 71st space launch this year.

By now, CAS Space has used Kinetica 1 rockets to help clients deploy 75 satellites with a combined weight of more than 10 metric tons, the rocket company said.

The Kinetica 1 model — with a length of 30 meters, a diameter of 2.65 meters, and a liftoff weight of 135 tons — is capable of deploying satellites with a combined weight of 1.5 tons to a typical sun-synchronous orbit about 500 kilometers above Earth.
