China has made progress on a powerful rocket engine to power its new reusable rockets.
A 130-ton-thrust, reusable kerosene-liquid oxygen engine aced a pair of consecutive ground ignition tests on Sunday (April 14). This means the engine — key to the development of the nation's new, reusable rockets — has now passed 15 repeated tests, 30 ignition starts, and more than 3,900 seconds cumulative hot fire testing, according to Global Times.
