Isar Aerospace's Spectrum rocket returns to the pad for its second launch attempt
ISAR Aerospace 5 Sept Mission Onward and Upward

German launch startup Isar Aerospace is targeting September 5 for the second flight of its Spectrum rocket, a qualification mission from Andøya Space in Norway. The mission will carry five CubeSats and one experiment, and follows multiple scrubbed attempts due to weather, a range violation by an unauthorized boat, and a pressurization valve issue. CEO Daniel Metzler emphasizes the goal is to learn as much as possible and demonstrate reliable access to space.
“Access to space remains one of the biggest constraints for the space industry and national security architecture. We have built the infrastructure and capabilities to change that.” — Daniel Metzler, CEO and Co-Founder of Isar Aerospace
