In a surprise launch, China debuts another big rocket designed for reusability

The race to field China's first reusable launch vehicle is far less predictable than a similar competition that played out in the United States a decade ago. There was never any real question of which company would develop and demonstrate the first reusable orbital-class rocket in the United States. SpaceX landed a Falcon 9 booster for the first time in 2015, and a little more than a year later, it launched it back into space.
