I've had the chance to visit the Ottobrun assembly hall of the Spectrum rocket in 2022.
It had a vibrant atmosphere, and the teams were iterating at high speed over various designs through the use of additive manufacturing including for the combustion chamber of their liquid oxygen and propane engine.
Such a huge moment that the teams have been working towards. Go Team Isar, best of luck for tomorrow's launch attempt! 🚀🇪🇺🫶
