China launches one other Gaofen Earth remark satellite tv for pc – Spaceflight Now

A brand new optical Earth remark satellite tv for pc launched by China Monday joins the nation’s distant sensing community for land surveys, city planning, and agriculture monitoring.

The Gaofen 11-02 distant sensing satellite tv for pc lifted off at 0557 GMT (1:57 a.m. EDT) Monday from the Taiyuan launch base in northern China aboard a Lengthy March 4B rocket.

The 154-foot-tall (46.9-meter) liquid-fueled rocket flew south from Taiyuan, situated within the northern Chinese language province of Shanxi, to put the Gaofen 11-02 satellite tv for pc into an elliptical orbit between 151 miles (244 kilometers) and 429 miles (691 kilometers) at an inclination of 97.three levels to the equator, in accordance with U.S. army monitoring information.

The spacecraft deployed from the Lengthy March 4B’s third stage in orbit round 13 minutes after liftoff.

The Gaofen 11-02 satellite tv for pc is a foll0w-up mission to China’s Gaofen 11 satellite tv for pc, which launched on a Lengthy March 4B rocket in July 2018. Each missions are a part of China’s Gaofen constellation of Earth-imaging satellites.

Chinese language state media mentioned the Gaofen 11-02 optical distant sensing satellite tv for pc has a decision of higher than 1 meter, or about three.three ft. The spacecraft “might be primarily used for land surveys, metropolis planning, land rights affirmation, street community design, crop yield estimation and catastrophe prevention and mitigation,” China’s state-run Xinhua information company mentioned.

The Gaofen 11-01 and 11-02 satellites will work collectively in orbit to enhance the community’s observing effectivity, Xinhua mentioned.

China’s Gaofen satellites are a part of the China Excessive-Decision Earth Remark System, or CHEOS. Chinese language officers say the CHEOS satellite tv for pc fleet is a civilian-operated program comprising optical and radar imaging spacecraft, and authorities have printed high-resolution imagery taken by earlier Gaofen satellites.

Beginner video posted on social media platforms appeared to point out the primary stage of the Lengthy March 4B rocket crashing again to Earth following Monday’s launch. Area missions lifting off from China’s inland spaceports sometimes drop spent rocket phases on land, and sometimes close to populated areas.

China’s latest launch web site, situated on Hainan Island within the south of the nation, permits rockets to fly on trajectories over the ocean.

Chinese language Lengthy March 2, three and four rockets burn a poisonous mixture of hydrazine and nitrogen tetroxide propellants. One of many movies posted Monday reveals a cloud of brownish-orange vapor rising from the rocket crash web site in a populated space.
