Nasa has completed a series of tests on a 3D-printed part of the F-1 engine at its Marshall Space Flight Center in Huntsville, Alabama, US.
The rocket engine had been developed to propel the Saturn V rockets on missions to the moon.
In 2013, engineers tested a vintage F-1 gas generator on the same stand. The generator supplies power to fuel a pump that delivers propellant to the engine, and generates around 30,000lb thrust.
In the latest test, the team evaluated the capabilities of a gas generator produced using additive manufacturing techniques.

April’s full moon will be the biggest and brightest of the year, appearing as the first of only two supermoons in 2021.
The rare spectacle occurs when the moon is approaching its closest point to Earth in its orbit, with the next one taking place almost exactly one month later on 26 May.
This month’s supermoon will peak at 4.31am BST on 27 April, but will appear full in the sky to casual observers on each day either side.
April’s full moon is traditionally referred to as the Pink Moon by Native American tribes and colonial settlers to the US.
