A Long March 11 rocket successfully sent the Hongyun-1 satellite into orbit late on Friday, marking first step in a 156-satellite low Earth orbit communications constellation planned by a major Chinese state-owned defence contractor.

Launch took place at 23:51 UTC December 21 (07:51 Beijing time December 22) at the Jiuquan Satellite Launch Centre in the Gobi Desert, sending Hongyun-1 into a Sun-synchronous orbit with an altitude of around 500 kilometres.

Hongyun-1 is the first satellite for the low Earth orbit global communications constellation of the same name, meaning 'rainbow cloud', first announced by the China Aerospace Science and Industry Corpopration (CASIC), the country's largest missile maker, in 2016.

"Using a common expression, we are moving the Internet currently on the ground into the sky. The first satellite of the Hongyun Project is China's first true low-orbit broadband communication satellite, which will greatly promote the development of space sectors, particularly commercial space," Hou Xiufeng, a CASIC spokesman, told CCTV.

CASIC aims to have the 156-satellite system, with most at an altitude of 1,000 kilometres, operational by around 2022.

Hongyun-1, will be used to verify low Earth orbit (LEO) broadband communication technologies, and also carries AIS (automatic identification system), ADS-B (automatic dependent surveillance) and DCS (data collection system) payloads.

Curiously, the launch vehicle was provided by the China Aerospace Science and Technology Corporation (CASC), a sister state-owned enterprise and the country's largest space contractor.

CASC confirmed launch success around 40 minutes later. CASC also announced that is now aiming to carry out the first sea launch of a Long March 11 in June 2019.

The company also stated it has carried out various improvements to the rocket, including guidance design and flight control software.

"With the development of technology of the launch vehicle, we will increase the carrying capacity of launch vehicles to two tons. This will further reduce the cost of sending satellites to space," Li Tongyu, a director with the the China Academy of Launch Vehicle Technology (CALT) under CASC, told CCTV.

News of the launch was first announced via Chinese media on Wednesday (link in Chinese), stating a launch on December 21 Beijing time, with the later airspace closures confirming the mission for one day later.

JIUQUAN, Dec. 22 (Xinhua) -- China launched a technology experiment satellite (TES) as part of its Hongyun Project, a low-orbit broadband communication satellite system, on Saturday morning.

A Long March-11 rocket carrying the TES blasted off from the Jiuquan Satellite Launch Center in northwest China at 7:51 a.m., before successfully entering its preset orbit. As the first satellite of the Hongyun Project, the successful launch signifies China's substantial progress in mapping the low-orbit broadband communication satellite system, said the China Aerospace Science and Industry Corporation (CASIC), a state-owned spacecraft developer.

With this TES, China will extend the test and application demonstration of low-orbit space-based Internet technologies, said CASIC.

The mission was the 295th mission of the Long March carrier rocket series, which was developed by the China Aerospace Science and Technology Corporation (CASC).

The Hongyun Project is designed to be a low-orbit globe-spanning broadband Internet access network based on a satellite constellation of 156 satellites.

The project features the integration of communication, enhanced low-orbit navigation and verified remote sensing, which are all reliant on space-based Internet access capabilities.

The project is also expected to bring broadband Internet access to remote areas in China, representing a major step for China in applying advanced tech, such as the multi-beam millimeter-wave phased array communication antenna, to the in-orbit test, said CASIC.

Moreover, it represents a major step in China's commercialization and industrialization of space technologies.

After the launch of the first experimental satellite, four more satellites will be launched by 2020 to form a satellite constellation.

By the middle of the 14th Five-Year Plan (2021-2025), all 156 satellites will be capable of meeting stipulated comprehensive operation requirements.

According to its developer, they will be tailored for various kinds of signal receivers such as fixed, portable and vehicle-mounted receivers, in order to meet demands from different users.

On orbit about 1,000 kilometers above the ground and banking on the low temperature and vacuum in space, the launch marks a positive exploration in the protection and backup of species resources.

It helps prevent the risk of losing such resources and may provide the last defense of original gene data of species on earth, protecting it from human influence.

The South China tiger used to inhabit eastern, central and southern China, and stands out as a tiger species unique to China. Living South China tigers are currently seen only in zoos.

The transport this time was arranged in partnership with Endless Door, an aerospace technology company in Shenzhen, Guangdong province, which has jointly developed containers for the dried DNA powder together with China Academy of Launch Vehicle Technology.

The container is designed to safeguard against space radiation and sudden high temperatures.

Previous research has proven successful storage of human and animal gene samples can be achieved in orbit.
