China’s sprawling state-owned rocket developer, maker of the country’s Long March rocket family, announced it recovered a reusable orbital-class booster for the first time Friday in the South China Sea.

The milestone mission began with the liftoff of a Long March 10B rocket from the Wenchang Commercial Space Launch Site on Hainan Island, China’s southernmost province. Powered by seven kerosene-fueled engines, the approximately 209-foot-tall (63.6-meter) rocket took off at 12:15 am EDT (04:15 UTC), or 12:15 pm local time at the seaside spaceport at Wenchang.
