Tech breakthroughs make new Prometheus rocket engine ten times cheaper

The next generation of spacecraft, looking beyond 2030, will be powered by a rocket engine using breakthrough technology. The Prometheus is a liquid oxygen (LOx)-methane engine. It is reusable, cheaper than hydrogen alternatives, and under development to dramatically reduce the cost of rocket production. Prototyping of the engine started 2015, making use of metal 3D printing methods. Its predecessor, the Vulcain 2.1 model – from 2014 – was developed by the company then known as Snecma and now called Safran. The Vulcain contains 3D printed structural components. Made by GKN Aerospace, the rocket nozzle of Vulcain 2.1 is the […]
