A research team led by the National Astronomical Observatories under the Chinese Academy of Sciences discovered 3 new FRBs with a high-dispersion measurement from the mass of data of China's Five-hundred-meter Aperture Spherical radio Telescope (FAST).
The discovery was published last week in The Astrophysical Journal Letters journal last week. The newly discovered FRBs, together with the first FRB captured by FAST in 2020, suggest there could be as many as 120,000 detectable FRBs arriving on Earth every day, according to the study. Based on the data from FAST, the scientists are expecting more discoveries while catching up with data processing.

On the occasion of the International Women's Day, a portrait of Zhang Yuhua, the Deputy Chief Commander of the Chang’e 5 and Tianwan 1 space missions, was published by the online portal shine.cn. Zhang Yuhua looks back at a 3 decades long career at SAST. After graduation in 1990, she was assigned to work at SAST, just when China’s manned, lunar and Mars space missions were beginning. “I was lucky to get in on the ground floor of China’s aerospace industry,” she said. Zhang encountered her biggest setback in 2014, when the six-wheeled Yutu 1 rover, designed by her team, malfunctioned on its second lunar day. She suffered insomnia for three days and cried alone in her room, she said.

Rocket manufacturer iSpace said on 1 March on its WeChat account that it has completed investigation of its launch failure, vowing that the firm will ramp up efforts on management and technology improvement. "Following 28 days of investigation and analysis, we have completed problem location analysis, fault simulation and recurrence, test verification and assessment and improvement measures." The flight failure of the SQX-1 Y2 rocket was located within a piece of insulation foam that had fallen off and fell on the IV grid rudder, causing the rudder to be blocked under aerodynamic pressure, and the foam was blown off again from the rudder later during the flight. After the rudder resumed the control system to track the command, the rudder deflection angle completed a deflection of more than 30 degrees in a short time, which caused a sudden change in the attitude of the rocket body, which led to the failure of the flight, according to the firm's analysis.
