Isar Aerospace

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.

Demand for launches is surging! Isar Aerospace is teaming up with @Astroscale_UK to launch the ‘ELSA-M’ mission—our first active debris removal flight, paving the way for a cleaner, more sustainable space, and boosting Europe’s space capabilities! Read more: isaraerospace.com/press/isar-aer…

To secure Europe's sovereignty in space, we must build it here. Today, German Chancellor @bundeskanzler Friedrich Merz and Norwegian PM @jonasgahrstore, joined by cabinet members, saw our Andøya launch site and 'Spectrum' launch vehicle firsthand – the infrastructure opening the German-Norwegian gateway to space.

With a newly signed agreement at @MunSecConfto, GER and NOR are taking action to strengthen Europe’s space infrastructure. Thank you @toreosa and @Forsvarsdep for visiting us to see firsthand our serial manufacturing capability built to deliver space access to NATO and its allies.

Sovereign space capability is not defined by one launch. It is the ability to unlock space on your own terms. With our 40,000 m² headquarters, which will produce up to 40 rockets per year when fully ramped up, we are building the foundation of Europe’s space industry.

We’re expanding testing capabilities @SSCspace! Isar Aerospace is building a second test site to support our ‘Spectrum’ rocket ramp-up. The new facility will enable integrated engine and stage testing—moving us closer to truly scalable space access. More: isaraerospace.com/press/isar-aer…

Launch is the crucial first step to building sovereign space capabilities. Germany is recognizing the need for a rapid increase in launch infrastructure. Thank you to Minister Pistorius and @Markus_Soeder for inviting us to today's opening of the Armed Forces Innovation Center.

After resolving the pressurization valve issue identified during the first launch attempt, a new launch window for Mission ‘Onward and Upward’ will open no earlier than 19 March from @AndoyaSpace, subject to weather and range availability. More: isaraerospace.com/press/new-avai…

Following the launch attempt on Wednesday, 21 January, which was scrubbed to address an issue with a pressurization valve, we are taking additional time to complete targeted checks and preparations before the next launch attempt. More updates to follow.

Mission ‘Onward and Upward’ will be moved to new launch window We are standing down from today's launch attempt to address an issue with a pressurization valve. The teams are currently assessing the next possible launch opportunities and a new target date will be announced shortly. Stay tuned for more information.

Mission ‘Onward and Upward’ will be broadcast live on YouTube: youtube.com/live/MsbZj8Pxm… The livestream will start at approximately: NET 21 Jan T-01h00min 8:00pm CET 7:00pm UTC 2:00pm ET Status updates will be shared throughout launch day. Stay tuned!

Payload integration complete for mission ‘Onward and Upward’. Our launch vehicle 'Spectrum' will carry 5 CubeSats and 1 experiment on its qualification flight, targeting launch NET 21 January 2026 from Andøya Space.
