Scientists have developed a rocket which can be vary deeply throttled from 8% up to 104% of its normal operating power. They have also found ways to control the chugging which usually affects the operation of this type of engines. Throttling engines are difficult to make because destructive vibrations can build up in the nozzle and critically damage the sensitive engine and spacecraft.
