NASA Wants Aerojet Rocketdyne to Make More Rocket Engines with 3D-Printed Parts

On its first launch, NASA‘s uncrewed Space Launch System (SLS) mega-rocket will go on a trip around the Moon as part of the initial test flight for the Artemis 1 mission. It will mark the beginning of one of the most talked-about space programs this year, Artemis, an ongoing government-funded crewed spaceflight initiative with the goal of landing the first woman and the next man on the Moon by 2024, particularly, on the lunar south pole region. The most powerful rockets ever built, the SLS is in turn powered by four super engines that are designed to handle some of the most extreme temperatures as they move massive amounts of propellants to generate enough energy for the rocket to escape Earth’s gravity.
