Isar Aerospace

Opening space for future generations.

[Isar Aerospace @isaraerospace]

We are standing down from today’s launch attempt. We are still detecting off nominal behavior in the vehicle's fluid systems, the teams are analyzing the new data to isolate the root cause.

[Isar Aerospace @isaraerospace]

We are targeting NET 15 June to launch Mission 'Onward and Upward' during the available launch window opening at 8:00 pm UTC (10:00 pm CEST), subject to weather, safety, and range infrastructure.

We’ve raised €270 million in Series D funding. This strategic backing powers our global expansion, accelerates serial production of our Spectrum launch vehicle, and drives new global launch sites. Backed by leading European and international investors, we deliver scalable orbital launch systems to secure sovereign space access for Europe, NATO, and allied nations.

True sovereignty in space starts with launch. We are joining forces with TKMS to build a sovereign space launch capability for Canada – strengthening the Canadian space ecosystem and serving as a lighthouse project for NATO's responsive launch readiness.

We are standing down from today’s launch attempt to evaluate a suspected leak in a composite overwrapped pressure vessel (COPV). The teams are assessing and will determine next steps.

Targeting NET 9 April for the launch of Mission ‘Onward and Upward’ during the available launch window, which opens at 8pm UTC; 10pm CEST.
The final date remains subject to weather, safety and range infrastructure.

[Isar Aerospace @isaraerospace]

Yesterday, Isar Aerospace was set to launch its qualification flight for Mission ‘Onward and Upward’ from Andøya Space during a 15 minute launch window. While all operations and check-outs were nominal throughout the countdown, Isar Aerospace was informed about an unauthorized vessel intruding the designated danger zone at sea. Shortly before the launch system entered final autosequence, the launch was placed on hold for 15 minutes. The range could only be declared clear at 21:18, and the countdown resumed.

As a result of the delay, the vehicle encountered an increase in engine fuel temperature, which could not be addressed within the shortened countdown and hence forced the abort of the mission.

Daniel Metzler, CEO and Co-Founder of Isar Aerospace: “Rocket launches are highly complex operations – from safe ground infrastructure to more than 100,000 parts, structures, and systems working together seamlessly. While we're working to return to the pad as quickly as possible, we will not compromise on mission assurance.”

Mission ‘Onward and Upward’ scrubbed

The launch of our qualification flight has been aborted during autosequence. After a hold in countdown due to a range violation of the danger area by an unauthorized boat, the countdown reset exceeded our launch window.
Isar Aerospace is working to determine a new launch window together with Andøya Space. Further updates will follow as soon as possible.

[Isar Aerospace @isaraerospace]

Mission 'Onward and Upward' is on track for launch at NET 9pm CET today, subject to weather, safety and range clearance. Propellant loading has started and the teams continue to monitor all systems and prepare for launch.

[Isar Aerospace @isaraerospace]

We are back on the pad at @AndoyaSpace with our launch vehicle ‘Spectrum’ getting ready for Mission ‘Onward and Upward’. The launch window opens not earlier than 25 March, 9pm CET, subject to weather, safety and range infrastructure.
