Isar Aerospace set for second launch of Spectrum rocket

The European private space launch provider Isar Aerospace, headquartered in Ottobrunn, Germany, is planning to fly its Spectrum small satellite launcher on its second flight. About a year after Spectrum's first flight failed, the company has scheduled the "Onward and Upward" mission for launch on Wednesday, March 25, at 20:00 UTC from the Orbital Launch Pad at the Andøya Spaceport in Norway. The launch window lasts until 20:50 UTC.

Spectrum's first flight, "Going Full Spectrum," launched on March 30, 2025, but failed after just 30 seconds into flight when the rocket lost attitude control after starting a pitch over maneuver.

Spectrum had been scheduled to fly on Jan. 21 but that attempt was scrubbed due to a faulty pressurization valve. The launch was rescheduled for March 19 but was pushed back several times due to weather concerns.
