This week's Rocket Report highlights fresh funding for European launch startups and a fourth attempt by Isar Aerospace to reach orbit with its Spectrum rocket, alongside signs that NASA is rethinking how it procures launches. The developments underline the growing competitiveness of Europe's commercial space sector, which is racing to reduce reliance on non-European launch providers, while NASA's move towards consolidated, bulk launch purchasing could reshape how it contracts with commercial rocket companies.

Isar Aerospace's Spectrum rocket has a weeklong launch window opening at Andøya Spaceport in Norway, having previously failed on its maiden flight and suffered repeated delays since January; the attempt coincides with Norway's period of mourning for the late King Harald V, though officials say launches can proceed as normal. Isar recently won a €200 million ESA contract, while Spanish firm PLD Space raised a further €108 million ahead of its Miura 5 debut and secured a €159 million ESA contract, and German company HyImpulse extended its funding by over €50 million to bring its total to €125 million. Separately, NASA is considering creating a new Commercial Access to Space office to consolidate launch procurement and enable bulk buys, echoing an approach already used by the US Space Force, while Blue Origin's New Glenn remains grounded following a May pad explosion, with a return to flight targeted by year-end.
