The launch was planned for tonight 21:00 CET. Isar Aerospace has called off the launch for today and moved it to a new launch window to address an issue with a pressurization valve. The new launch window will be announced shortly. We expect it for tomorrow evening #Spectrum #Andøya #Space #science

Isar Aerospace has still not given an update to the launch window. A launch today is not realistic anymore. We will update you as soon as Isar Aerospace will publish new information. The launch will be covered in this thread/ticker. #Spectrum #Space #science #IsarAerospace #Europe #Germany

Isar Aerospace published a new media statement to the issue with one pressurization valve. They need additional time to complete preparations and targeted checks. The new launch time will be announced soon. This live ticker/thread remains open and updated for fresh updates. #Spectrum #Space #Europe

Isar Aerospace has published a new media statement, saying they have resolved the issue with the pressurization valve. A new launch window will open no earlier than 19 March at Andøya Space Port. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #Europe #EU #NewSpace #Germany #Space

Isar Aerospace wants to demonstrate real progress, and have to push their systems once again to the limits to achieve that. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

Our live coverage in this ticker/thread will continue March 19, 2026 with the launch or if news are being published before. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

Isar Aerospace has confirmed the launch appointment for today, March 25, 2026 at 21:00 CET from Andøya Space. Our live coverage will resume at around 20:30 CET. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

Welcome back to our live coverage with a first look to the Spectrum rocket. It's 30 minutes to launch. Photo: NSF / Isar Aerospace #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

Isar Aerospace is currently building a new productions hall in Munich to have a second and almost fully automatic production facility for the Spectrum rocket's parts. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

The name Spectrum was chosen to represent the whole range of systems needed to built and launch the rocket. 1000kg of payload can be transported to Earth orbit. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

The engine is operated with liquid oxygen and liquid hydrogen. The rocket has 9 Engines, 8 in the lower stage, 1 engine in the upper stage. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

The engines can handel the sea-level conditions and the space-level conditions. This is new and special, because only one type of engine needs to be produced - 3D printed - to bring the rocket into Earth orbit. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #Europe #Space #science

The Spectrum rocket carries more than double of the liquid oxygen then other propellant, because the rocket needs the oxygen to move in space, as it can not get oxygen naturally from the environment. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #Europe #NewSpace #Space

In the current times, independent access to space has become an important factor in the world. Today Germany and Europe will enter a new era of independent space access. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

The German chancellor and Minister of Defence have visited the space port this week, showing that this next step in the German space industry is important. We are 15 minutes away from launch. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #Europe #NewSpace #Germany #Space #science

15 cubits are the payload of the rocket. This flight should bring them to earth orbit, the first time from continental Europe. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

This happens 9 months after the first test flight that crashed into the ocean. The stage engine tests of this flight have started in December 2025. Spectrum 3 is already in the final productions phase in Munich. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #Europe #Space #science

We have a delay now. The countdown has moved to T-24 minutes. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

The launch is delayed because there is a boat in the range area of the space port. The launch has been paused for the moment until the boat has moved out of the range of the space port. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Germany #Space #science

The range is clear. Countdown is under 10 minutes now, we have entered the automatic sequence range. 7 minutes to go. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

We are still at automatic sequence. 3 minutes to go. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

Less than 2 minutes to go. Good luck and safe flight for Isar Aerospace and Spectrum 2. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

We have an abort 1 second before launch. More information will follow. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

Isar Aerospace says, the delays in the launch is reason for the hold as we have left the launch window for tonight. There will be no launch today. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science

We will keep you updated with the new launch date. This ticker/thread will continue as soon as we have the latest information and the new launch date is announced. #IsarAerospace #Spectrum #OnwardUpward #Andøya #AndoyaSpacePort #SpaceExploration #Europe #EU #NewSpace #Germany #Space #science
