China sent a classified experimental satellite to orbit on Friday (Oct. 28), continuing a busy October for the nation.
The Shiyan-20C spacecraft lifted off on Friday at 9:01 p.m. EDT (0101 GMT and 9:01 a.m. Beijing time on Oct. 29), riding a Long March 2D rocket into the sky from Jiuquan Satellite Launch Center in northwestern China.
The 2,650-pound (1,200 kilograms) Shiyan-20C was successfully inserted into an orbit about 435 miles (700 kilometers) above Earth, NASASpaceflight.com reported (opens in new tab), citing the China Aerospace Science Corporation.
“The satellite will be mainly used for in-orbit verification of new technologies such as space environment monitoring,” the state-run media outlet Xinhua wrote.
This vague description is fairly standard for the Shiyan satellites, whose name translates as “experiment.”
The Shiyan constellation is a relatively large one, consisting of 22 spacecraft now that Shiyan-20C is aloft, according to NASASpaceflight.com. The satellites likely do a variety of jobs and test a range of new technologies.
China has now launched six orbital missions this month, including a very high-profile effort today (Oct. 31).
That most recent liftoff sent the Mengtian module skyward atop a Long March 5B rocket. Mengtian is the third and final piece of China’s T-shaped Tiangong space station. Its arrival, expected later tonight, will mark the end of Tiangong’s assembly phase and the beginning of full operations for the orbital outpost.
