China confirmed its Kuaizhou-11 rocket failed after launching today (July 10) from the Jiuquan Satellite Launch Center in northwest China. The cause for failure is currently being evaluated.

This failure comes just one day after the country launched another rocket type successfully from the Xichang Satellite Launch Center in southwest Sichuan China.

A press release from state media source Xinhua stated that a "malfunction" happened after the liftoff at 12:17 p.m. Beijing time (12:17 a.m. EDT or 0417 GMT). "The specific cause of the failure is under further analysis and investigation," Xinhua added.

Video footage of the launch, which is available via a delayed stream, shows that the rocket worked well in the first minute of the launch and the first and second stage separations appeared to be successful, according to

Kuaizhou-11 (also known as KZ-11) was attempting to launch on its first mission after several delays in development and was carrying two satellites into space. The rocket was first developed in 2015 and its first launch was initially scheduled for 2018, according to

There were two satellites on board the failed rocket. CentiSpace-1 S2 (also referred to as Xiangrikui 2 or Weili-1-02 in media reports) was part of a satellite series for low-Earth orbit navigation. Jilin-1 Gaofen-02E (also called BilibiliSat) is a remote sensing satellite intended for commercial applications, specifically for managing geological disasters and natural resources.

KZ-11 was developed by the China Aerospace Science and Technology Corp. and commercialized by the China Space Sanjiang Group Corporation (Expace), according to The rocket can send up a payload with a mass of up to to 220 pounds (100 kilograms) to sun-synchronous orbit in a medium-altitude Earth orbit that allows for consistent lighting conditions below. Alternatively, it can send a payload of up to 3,300 pounds (1500 kg) to low-Earth orbit. A KZ-11 represents one of several commercial efforts in China to supplement the country's traditional reliance on government-funded launches, an analyst told

While this launch, which was the 19th launch from China in 2020, resulted in failure, the country's 18th launch of the year which took place the day before successfully lifted the APSTAR-6D telecommunications satellite into space aboard the veteran Long March 3D rocket type. This launch was captured in footage by state media source China Central Television (CCTV). It blasted off at 8:11 p.m. Beijing time (8:11 a.m. EDT or 1211 GMT) on Thursday (July 9).

APSTAR-6D is expected to last about 15 years in space in geostationary orbit, as part of a broadband satellite communications system serving the Asia-Pacific region, CCTV added in a news report. The satellite is designed to provide high-speed communications with a capacity of about 50 gigabytes per second. 

The APSTAR-6D satellite was developed by the China Academy of Space Technology, a subsidiary of China Aerospace Science and Technology Corp. The satellite was purchased by APT Mobile SatCom Limited in 2016.

Should APSTAR-6D work, it will be the first time China's Dongfanghong-4 satellite platform (DFH-4E) will be used in space. DFH-4E has components meant to reduce the mass of the satellite platform and to create more room for payloads on the rocket, according to

DFH-4E's launch comes after two earlier failures of the platform, SpaceNews added. A ChinaSat-18 spacecraft power failure occurred immediately after launch in August 2019 and a second attempt in April this year saw the Long March 3B rocket and the Nusantara-2 Indonesian satellite destroyed.
