China’s new Lengthy March 7A rocket efficiently launched its first orbital mission after its first attempt one yr in the past ended with a failure.
The rocket lifted off from the Wenchang Satellite tv for pc Launch Middle on China’s Hainan Island on Thursday (March 11) at 12:51 p.m. EST (1751 GMT, or 1:51 a.m. native time March 12), based on the Chinese language state-run media outlet Xinhua.
It lofted into orbit a categorized experimental satellite tv for pc known as Shiyan-9 (which means “experiment-9”), which was developed by the China Academy of Area Expertise, based on a report from SpaceNews.
“The satellite tv for pc shall be primarily used for in-orbit checks of latest applied sciences together with area atmosphere monitoring,” Xinhua said in its report.

When China tried to launch the brand new Lengthy March 7A rocket on its debut flight on March 16, 2020 — virtually precisely one yr in the past — an engine malfunction occurred shortly after first stage separation and the payload was misplaced, SpaceNews reported.
The brand new rocket is meant to exchange China’s workhorse Lengthy March 3B rocket because the go-to launch automobile for sending satellites right into a geosynchronous transfer orbit, or the trail satellites take to achieve a geostationary orbit excessive above the Earth. It’s a modified model of the Long March 7 rocket, which debuted in 2016 and has launched two missions to low Earth orbit.
To achieve a geosynchronous switch orbit, a rocket should launch the satellite tv for pc into an elliptical orbit that extends to about 23,000 miles (37,000 kilometers) above the Earth, according to NASA, whereas satellites in low Earth orbit are 100 to 200 miles (161 to 322 km) above the Earth.
The Lengthy March 7A can also be able to lifting heavier payloads to orbit, with a carrying capability of eight tons (7 metric tons), versus the Lengthy March 7’s 6-ton (5.5 metric tons) carrying capability, based on Xinhua.
China is planning to launch three to 5 Lengthy March 7A missions per yr earlier than 2025, Xinhua stated, including that “scientists will additional improve the launch automobile to satisfy the demand for sending satellites and deep-space probes to discover the moon, Mars and asteroids.”
