Isar Aerospace plans to conduct its inaugural test flight of the Spectrum rocket on Monday in Norway between 12:30 p.m. and 3:30 p.m. local time. The launch depends on weather conditions, safety protocols, and range infrastructure. The company aims to gather data from this first integrated test, with a 30-second flight deemed a success. The Spectrum rocket stands 28 meters tall and is designed to launch small and medium-sized satellites into orbit.
