Europe's Isar Aerospace rocket launch scrubbed again

Isar Aerospace's crucial test flight for its Spectrum rocket has been postponed for the fourth time in five months due to issues with the vehicle's fluid systems. This latest delay highlights the challenges faced by European commercial space startups aiming to compete with established providers. The company, which has secured significant funding, is now analyzing data to identify the root cause of the problem. Previous launch attempts were also scrubbed due to valve issues, fuel temperature anomalies, and a suspected leak. The remote launch site in Norway also faces scheduling conflicts with military exercises and local fishing interests, adding further complexity to the launch process.
