As preparations for the upcoming Shenzhou-20 manned space mission enter their final stage, Chinese aerospace professionals at the Xi'an Satellite Control Center are working diligently, refining every step and detail to ensure the success of the mission.
Located in Xi’an, capital of northwest China's Shaanxi Province, the control center manages everything from flight trajectory design and software engineering to command and control.
At the Qingdao telemetry, tracking and command (TT&C) station, a branch of Xi'an Satellite Control Center located in east China's Qingdao City, Shandong Province, senior engineer Zhang Zhuo and her colleagues were working on joint system debugging as they prepared for the launch of the Shenzhou-20 mission.
Zhang, a 23-year veteran, has developed a routine of writing down detailed notes while working, which helps her remember important information and provides guidance when she encounters technical problems.
"Taking work notes comes naturally to me, just like breathing, eating, and drinking," said Zhang.
Zhao Dan, as the first female operator at the Xi'an Satellite Control Center has constantly enhanced her professionalism through overcoming challenges in her work.
"Becoming a Huashan (code name for Xi'an Satellite Control Center) operator is both an acknowledgment of my abilities and a source of motivation. As space TT&C tasks intensify, the challenges ahead will also grow greater," said Zhao.
In addition to Zhang and Zhao, there are many other dedicated aerospace professionals who have been working diligently and contributing to the progress of China's space program.
"In my work, the mouse and keyboard are like the needles for an embroiderer, while some of the algorithms and codes I write are like the techniques used by the embroiderer. We hope to carry forward this spirit of craftsmanship, creating a map of China's space orbits in the vast expanse of the universe," said Wang Lusha, an aerospace worker at the center.
