IN A SURPRISE LAUNCH, CHINA DEBUTS ANOTHER BIG ROCKET DESIGNED FOR REUSABILITY

Summary from the TLDR newsletter

China tested its Long March 12B again on Monday. While the launch did not include any attempt to land the first stage booster, the rocket carried grid fins and landing legs, important elements for future recovery experiments. The China Aerospace Science and Technology Corporation declared the flight a complete success. First-stage recovery tests are scheduled to be carried out at a later, opportune time.
