China launches first of a brand new sequence of Yaogan reconnaissance satellites

HELSINKI — China launched its first Yaogan-42 satellite tv for pc late Tuesday, including to the nation’s rising army satellite tv for pc reconnaissance capabilities.

A Lengthy March 2D rocket lifted off from Xichang Satellite tv for pc Launch Middle at 6:56 p.m. Japanese (2256 UTC) April 2. The China Aerospace Science and Know-how Company (CASC) introduced launch success throughout the hour. CASC’s assertion additionally revealed the beforehand unknown payload to be Yaogan-42 (01) (“distant sensing-42 (01)”).

The satellite tv for pc was later tracked by the U.S. House Drive’s 18th House Protection Squadron (SDS) in a roughly 500-kilometer-altitude orbit inclined by 35 levels.

Each Yaogan-42 (02) and its Lengthy March 2D launcher have been developed and offered by CASC’s Shanghai Academy of Spaceflight Know-how (SAST).

Neither CASC nor Chinese language state media offered any particulars concerning the labeled satellite tv for pc. These statements omitted the standard normal description 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 embody “electromagnetic atmosphere detection and associated technical assessments.”

Outdoors observers assess Yaogan sequence satellites to be designated for army and civilian functions.

The assorted sequence 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 programs and different digital gadgets, with protection of each land and sea. 

The overwhelming majority of Yaogan satellites function in a sequence of low Earth and sun-synchronous orbits.  Some teams of Yaogan satellites, reminiscent of Yaogan-31, might be analogous to U.S. Division of Protection Naval Ocean Surveillance System (NOSS) satellite tv for pc triplets. Different teams, in orbits with inclinations of 35 levels, ang spaced 60 or 120 levels aside, present close to fixed surveillance over areas of safety concern near China.

Moreover China launched the Yaogan-41 satellite tv for pc in the direction of geosynchronous orbit in late 2023. That satellite tv for pc launched on a Lengthy March 5, China’s largest operational rocket. The mission A used a brand new, elongated 18.5-meter-long, 5.2-meter-diameter payload fairing.

Tuesday’s launch was China’s fifteenth orbital mission of 2024. The nation is aiming to launch round 100 instances throughout 2024. Round 70 shall be performed by CASC, with China’s business launch service suppliers planning round 30 launches. 

Industrial exercise will embody the brand new Tianlong-3 from House Pioneer. The 71-meter-long rocket shall be able to lifting 17 tons of payload to low Earth orbit, or 14 tons to 500-kilometer sun-synchronous orbit, in keeping with the agency. The rocket would turn out to be China’s second most succesful rocket, behind the Lengthy March 5. It’s supposed to have a reusable first stage sooner or later.

SAST plans to launch its new, 3.8-meter-diameter Lengthy March 12, beforehand known as the “XLV,” throughout 2024.
