Mission Updates

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.

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.

The second flight and qualification mission of Isar Aerospace's ‘Spectrum’ launch vehicle will be broadcast live on YouTube: https://www.youtube.com/live/MsbZj8PxmUk 

The livestream will start at approximately: 

• T-01h00min 

• 8:00pm CET 

• 7:00pm UTC 

• 2:00pm ET

As Isar Aerospace approaches its second flight and qualification mission, the teams have successfully integrated the payloads for Mission ‘Onward and Upward’.

Five CubeSats and one experiment will be the first payloads carried by Isar Aerospace’s in-house developed launch vehicle ‘Spectrum’.

Mission ‘Onward and Upward’ is supported by ESA’s Boost! program. Through Boost! Isar Aerospace won the first Microlauncher Competition of the German Space Agency at DLR, which resulted in the selection of the payloads we are carrying on board of this flight.

Space company Isar Aerospace is approaching its second flight and qualification mission from the company’s dedicated launch complex at Andøya Space in Norway, further advancing Europe’s sovereign space capability. The launch is targeted for not earlier than 21 January, with the launch window opening at 09:00 pm CET, subject to weather, safety, and range clearance. 

“This qualification flight is a deliberate step toward delivering sovereign access to space for Europe and allied nations. Just ten months after proving that launch vehicles can be designed, built, and launched from continental European soil, we’re ready to fly again. Europe’s immediate need for space access is clear. Rapid iteration is essential to developing space capabilities precisely when they are required,” said Daniel Metzler, CEO and Co‑founder of Isar Aerospace.  

Mission objective: operational qualification 

Andøya, 22 December 2025 – Less than nine months after Spectrum’s first test flight, Isar Aerospace has completed stage testing and is preparing for its second launch from the company’s dedicated launch complex at Andøya Space in Norway. Both of the vehicle’s stages passed 30-second integrated static fire tests, validating vehicle readiness for final integration and launch operations. 

“We are building more than rockets, we are building the capability for nations to access and sustain space on their own terms,” said Daniel Metzler, CEO and Co‑founder of Isar Aerospace. “Rapid iteration is how you win in this domain. Being back on the pad less than nine months after our first test flight is proof that we can operate at the speed the world now demands.” 

Following the first test flight of Isar Aerospace’s launch vehicle ‘Spectrum’ on 30 March 2025 from Andøya Spaceport in Norway, the company has completed a thorough investigation, further underscoring its commitment to safety.

Approximately 30 seconds into flight, ‘Spectrum’ received a termination order, resulting in an unpowered descent into the sea. The findings confirm that the flight safety system performed nominally throughout this phase of flight. At no stage did the launch pose a risk to public safety.

A comprehensive investigation was completed within two months of the launch. The findings identified an unintended opening of the vent valve and a loss of attitude control at the start of the roll maneuver as the initiating events that led to the in-flight failure. The investigation has been reviewed with the Norwegian Civil Aviation Authority (NCAA).
