Advancements in Rocket Nozzle Technology Propel NASA's Deep Space Missions

NASA has successfully built and tested a 3D printed rocket engine nozzle made of aluminum, which is lighter than conventional nozzles and has the potential to enable deep space flights with increased payload capacity. The nozzle, developed under the RAMFIRE project, utilizes a novel aluminum alloy that is heat resistant and weldable, overcoming the challenges associated with using aluminum for additive manufacturing of rocket engine parts. This advancement in lightweight, additively-manufactured aluminum rocket nozzles could contribute to NASA's objectives of sending more cargo to deep space destinations and support future missions to the moon, Mars, and beyond.
