HELSINKI — China launched its second Yaogan-42 reconnaissance satellite tv for pc over the weekend, weeks after sending the primary such satellite tv for pc into an identical orbit.
A Lengthy March 2D rocket lifted off from Xichang Satellite tv for pc Launch Middle at 7:45 p.m. Jap (2334 UTC) April 20. The China Aerospace Science and Know-how Company (CASC) introduced launch success throughout the hour.
CASC’s assertion revealed the beforehand undisclosed payload to be the second batch of Yaogan-42 satellites. Yaogan interprets to “distant sensing”.
Neither CASC nor Chinese language state media supplied any particulars relating to the satellites. These statements omitted common normal descriptions of Yaogan satellites.
Some Yaogan satellites are described as being for functions together with land survey, crop yield estimation, environmental administration, meteorological warning and forecasting, and catastrophe prevention and discount. Makes use of of others embrace “electromagnetic atmosphere detection and associated technical exams.”
Yaogan-42 (02) has been tracked by U.S. Area Power’s 18th Area Protection Squadron (SDS) in a 491 by 502 kilometer orbit inclined by 35 levels. That is much like the first Yaogan-42 satellite tv for pc, launched April 2, however with an angular separation of 142 levels.
Exterior observers assess Yaogan collection satellites to be designated for army and civilian functions.The varied collection of Yaogan satellites are understood to incorporate optical imaging, artificial aperture radar (SAR) and digital intelligence (ELINT) satellites.
This mixture offers high-resolution imagery and all-weather and all-day and night time imagery, together with the gathering of digital indicators from radar, communication methods and different digital gadgets, with protection of each land and sea.
U.S. considerations over Chinese language reconnaissance satellites
U.S. Officers have lately voiced concern over China’s buildup of reconnaissance satellites. Chief Grasp Sgt. Ron Lerch, of the Area Programs Command’s intelligence directorate, warned in January that China’s reconnaissance spacecraft are offering the Individuals’s Liberation Military unprecedented eyes in area to trace U.S. and allies’ actions in Asia-Pacific and different hotspots.
Notable additions to the collection embrace Yaogan-41 to geosynchronous orbit in late 2023. That satellite tv for pc launched on a Lengthy March 5, China’s largest operational rocket. The mission used a brand new, elongated 18.5-meter-long, 5.2-meter-diameter payload fairing. In the meantime, China launched Ludi Tance-4, regarded as the world’s first geosynchronous orbit SAR satellite tv for pc, in August final yr.
“Paired with knowledge from different Chinese language surveillance satellites, Yaogan-41 might present China an unprecedented potential to determine and observe car-sized objects all through all the Indo-Pacific area and put in danger quite a few U.S. and allied naval and air property working within the area,” Clayton Swope, a former U.S. intelligence official and now a senior fellow on the Middle for Strategic and Worldwide Research, mentioned in January.
Saturday’s launch was China’s seventeenth orbital mission of 2024. The nation is aiming to launch round 100 occasions throughout 2024. Round 70 can be carried out by CASC, with China’s industrial launch service suppliers planning round 30 launches.
CASC will launch two main missions within the subsequent couple of weeks. The Shenzhou-18 human spaceflight mission to the Tiangong area station is because of launch April 25 from Jiuquan, northwest China. The primary-ever lunar far facet pattern return mission, Chang’e-6, is scheduled to launch Might 3 from Wenchang.
