Because of years of coaching and painstaking efforts, north China’s Dongfeng Touchdown Web site has developed sturdy search and rescue capabilities to make sure the graceful operating of an essential hyperlink of the nation’s manned house program, stated a senior official of the positioning throughout an interview with China Media Group (CMG).
Positioned within the Gobi Desert in north China’s Interior Mongolia Autonomous Area close to Jiuquan Satellite tv for pc Launch Heart, Dongfeng Touchdown Web site was put into sensible use in September 2021, when it welcomed dwelling the three astronauts of the Shenzhou-12 manned house mission.
“We now have a mature search and rescue scheme. The Beijing Heart and Dongfeng Heart predict the touchdown level of the re-entry capsule in actual time, and the air and floor detachments begin off prematurely to the expected touchdown level,” stated Hu Xiaochun, deputy director of Jiuquan Satellite tv for pc Launch Heart and deputy commander of the touchdown website headquarters of China’s manned house program.
Hu stated that the night time seek for the Shenzhou-14 manned spacecraft in December 2022 was carried out easily.
“We ensured the arrival of helicopters and personnel as quickly because the spacecraft landed. Every activity, together with touchdown, opening the latch and taking the astronauts out of the cabin, was carried out in an interconnected and orderly method,” he stated.
Beforehand, China’s returning spacecrafts used to land at a website in Siziwang Banner in Interior Mongolia, whereas Dongfeng served as a backup website to make sure the meteorological circumstances on the touchdown website met the necessities for secure touchdown.
In December 2022, the Shenzhou-15 mission wrapped up the development of China’s house station and began the primary stage of its software and growth. Now, spacecraft can stay docked on the house station till the meteorological circumstances are correct for his or her return. There is no such thing as a longer the necessity to arrange a climate backup touchdown subject.
Dongfeng Touchdown Web site, with the help of highly effective telemetry, communications, meteorology and medical sources of Jiuquan Satellite tv for pc Launch Heart, is a better option for endeavor search and rescue missions.
“We now have upgraded the automobile and communication gear on the plane in an all-round means to make sure easy communication throughout the touchdown space. We now have additionally custom-made a particular automobile for medical supervision and healthcare,” Hu stated.
After the spacecraft descends into the Earth environment, it might solely depend on the bottom telemetry stations. Spacecraft monitoring is totally coated by the northwest telemetry belt. The entire technique of a spacecraft’s return is seen by means of reside broadcast, together with the second of touchdown, which is recorded from a number of angles.
Hu stated that the touchdown of the Shenzhou-12 manned spacecraft in September 2021 could be stated to be a significant take a look at of Dongfeng Touchdown Web site’s search and rescue plan, technical gear and personnel.
Along with the search and rescue missions, the staff on the website additionally prepares for a potential emergency rescue in the course of the mission launch.
“Within the 582 seconds from ignition to getting into orbit, the rocket undergoes many actions, comparable to engine ignition, separation of the primary and second phases, and separation of the fairing. Even when solely certainly one of these actions goes incorrect, the spacecraft can not enter orbit. In such a situation, the emergency rescue staff of our touchdown website system should be capable to deliver astronauts again safely from totally different places,” stated Hu.
In its most up-to-date mission on December 4, 2022, the positioning achieved China’s first search and rescue of a manned spaceship on a winter night time because the three-member crew of the Shenzhou-14 manned house mission returned safely with a distinction of some 200 meters between the precise and predicted touchdown factors. Such a excessive accuracy required exact calculation and management, Hu defined.
“After our nation’s BeiDou Navigation Satellite tv for pc System was put into use, the forecast mannequin of your entire re-entry course of is getting an increasing number of correct. In the meantime, the appliance of space-based telemetry supplies extra info sources for the prediction of the touchdown level,” he stated.
