China launches 2 rockets in 2 days, lofting 4 satellites to orbit

SpaceX's first astronaut launch wasn't the only spaceflight action last weekend.

While NASA and SpaceX were busy supporting the historic Demo-2 mission from Florida last weekend — the first crewed orbital flight from the U.S. in nearly a decade — the Chinese were making space strides of their own.

China once again picked up the pace of its launches with two successful rocket flights back to back, around the same time that Demo-2 blasted off toward the International Space Station on May 30.

China first launched two new technology-demonstrating satellites at 4:13 a.m. Beijing time on May 30 (4:13 p.m. EDT, or 2013 GMT, on May 29).

The satellites soared successfully into space aboard a Long March-11 rocket, which launched from southwest China, according to Chinese state media outlet CCTV.

"Peng Kunya, a chief designer of the Long March-11, said that it was the first time that the Long March-11 was launched from the Xichang Satellite Launch Center, proving its adaptability to different launch sites," CCTV said in its report.

Barely 36 hours later, China sent another satellite duo aloft from the country's northwest region. A Long March-2D rocket blasted off from the Jiuquan Satellite Launch Center on May 31 at 4:53 p.m. Beijing time (4:53 a.m. EDT or 0853 GMT).

One of the satellites on the Jiuquan launch was Gaofen-9. The civilian remote-sensing satellite can take photographs with a resolution of roughly 3.3 feet (1 meter), said state-sponsored media outlet Xinhua. "It will be used in land surveys, urban planning, road network design and crop yield estimates, as well as disaster relief," Xinhua stated.

Beijing-based HEAD Aerospace Technology Co. Ltd. created the other satellite, called HEAD-4. The satellite is designed to support the Internet of Things (IoT), which allows connected devices to send and receive information from orbit. HEAD-4's IoT service will also be used on ships and aircraft, Xinhua reported.

China was on a tear for much of late 2019, sometimes launching rockets mere hours apart at different space centers. The pace of spaceflight slowed in early 2020 when the novel coronavirus pandemic emerged.
