BEIJING, Jan. 12 (Xinhua) -- The following is a summary of published science and technology news of China.

CHINA'S SPACE-BASED SOLAR CAMERA

A China-developed space-borne solar camera studying the solar transition region released its first group of scientific data on Wednesday.

The 46.5-nanometer extreme-ultraviolet imager or Solar Upper Transition Region Imager (SUTRI), mounted on SATech-01 satellite, was launched into space on July 27, 2022, from the Jiuquan Satellite Launch Center in northwest China by a Lijian-1 carrier rocket.

SUTRI is the first solar imager in the world to work at a wavelength of 40 to 110 nanometers based on a multilayer narrow-band filtering technique, according to the National Astronomical Observatories of China under the Chinese Academy of Sciences.

ENERGY PARTICLE DETECTOR

A particle detector has been installed on the extravehicular platform of China's space station to obtain key data used for the space station's safety, extravehicular activities of the astronauts, biological experiments, and the study of space material.

The energy particle detector in Wentian lab has been transported via the cargo airlock cabin, assisted by a robotic arm.

The detector used a new material called CLYC for the first time in the world that can achieve high-efficient neutron detection.

CHINA'S HOMEGROWN LARGE JETLINER

The C919, China's first homegrown large jetliner, had gained 1,035 orders from 32 customers by the end of 2022, according to the Science and Technology Commission of Shanghai.

The first C919 aircraft was delivered to China Eastern Airlines in December 2022. The company is expected to put the aircraft into commercial operation by the spring of 2023.

The report also shows that by the end of 2022, the ARJ21, China's homegrown regional jetliner, had received 690 orders from 25 customers. Enditem
