Isar raises 270M euros, sets new Spectrum launch date

Isar Aerospace closed a 270 million euro Series D to scale production of its Spectrum rocket. The company scheduled the second launch attempt for June 15 to June 21, following the first Spectrum rocket's failure in March 2025. NASA plans to fly Blue Origin's test lander on New Glenn for Artemis III but acknowledged Vulcan and Falcon Heavy as alternatives.
