On July 5, 2018, Nammo conducted a final, successful ground test of the Nucleus rocket flight propulsion system, at the Nammo Raufoss Test Center. The groundbreaking hybrid rocket technology is now ready to power the first launch of a Norwegian-built space rocket in September 2018. All the components of the rocket were tested together on site – meaning that the team was able to get feedback on a complete, working rocket system. The motor was ignited and burnt for 40 seconds, until full depletion of the oxidizer and gas tanks.
