Isar Aerospace Spectrum "Onward and Upward" Scrubs at T-3 Seconds
72 FOMOIsar Aerospace's second Spectrum rocket, mission "Onward and Upward," reached T-3 seconds before engine ignition at Andøya Spaceport in Norway on March 25, 2026 when the countdown was aborted. A range violation by an unauthorized vessel delayed the window, during which propellant temperatures rose outside acceptable margins — forcing the scrub. The mission was designed as a qualification flight to SSO carrying five cubesats and one Dcubed experiment, supported by ESA's Boost! programme. No new launch date has been announced.
Why it matters
T-3 abort is simultaneously the worst and best place to scrub: you've proven the stack is ready but left the pad empty. The propellant temperature issue is a fixable ground ops problem, not a vehicle deficiency. Isar remains Europe's most credible path to first orbital launch from European soil.
