Overview
- - The company halted Thursday's planned second test flight about an hour before liftoff after teams flagged a suspected leak in a pressure tank at the Andøya site in Norway.
- - Engineers are inspecting the issue and have not set a new launch time within the window that was announced to run through April 19.
- - Spectrum is a two‑stage microlauncher built to carry up to one tonne to low Earth orbit, and this flight was set to carry five small satellites and a university‑industry experiment.
- - The program has seen repeated scrubs and setbacks, including a faulty pressure valve discovered in January, a March countdown halted by a fishing boat in the safety zone, and a first flight in March 2025 that failed after about 30 seconds.
- - A successful qualification would add a European option for dedicated small‑satellite launches, and CEO Daniel Metzler says Isar already holds contracts through 2028.
