BEIJING, Nov. 4 (Xinhua) — The following is a summary of published science and technology news of China:
REUSABLE ROCKET
China’s commercial reusable rocket SQX-2Y has successfully completed a vertical take-off and landing flight test, according to its developer i-Space, a Beijing-based rocket developer.
The 17-meter-tall demonstration rocket, designed to verify reusable carrier rocket technology, was lifted off at 2:00 p.m. on Thursday from the Jiuquan Satellite Launch Center in northwest China.
Propelled by a liquid oxygen methane engine, the rocket stage flew off the ground reaching an altitude of 178.42 meters. After more than 50 seconds, it landed at the target site smoothly at a speed of 0.025 meters per second. The landing position accuracy was about 1.68 meters.
CHIP
Chinese researchers from Tsinghua University have developed an all-analog photoelectronic chip that can process computer vision tasks with greater speed and energy efficiency than existing chips.
The research team’s findings, which provide an alternative to existing technologies based around analogue-to-digital conversion, have been published in the journal Nature.
In the new study, the researchers designed an integrated photoelectronic processor to harness the advantages of both light, in the form of photons, and electrons, as found in electric currents, in an all-analog way. The result is called an “all-analog chip combining electronic and light computing,” or ACCEL.
SATELLITE
China successfully sent a communication technology experiment satellite into space from the Wenchang Spacecraft Launch Site on the southern island province of Hainan on Friday.
The satellite was launched at 10:54 p.m. (Beijing Time) by a modified version of the Long March-7 carrier rocket and entered the planned orbit successfully.
The satellite will be mainly used for multi-band and high-speed communication technology experiments.
