Signatures between ESA and Avio have secured three missions to fly as auxiliary passengers on the Vega-C rocket from the European Spaceport in French Guiana.https://www.esa.int/Enabling_Support/Space_Transportation/Boost/Flight_Ticket_Initiative_first_five_missions_secured_with_Avio_and_Isar_Aerospace#msdynmkt_trackingcontext=68c284af-ec56-4d20-8cf7-1df2bd950300
Flying with Isar AerospaceSignatures between ESA and Isar Aerospace have secured two missions on the Spectrum launch vehicle from the Andøya Spaceport in Norway.Infinite Orbits will launch two satellites to demonstrate a space debris cleanup mission. The infinite orbit mission will reenact the approach between a servicing satellite and a piece of space debris in low Earth orbit. The mission being launched on Spectrum consists of two satellites: one will "pretend" to be an inactive piece of space debris, and the other will approach independently and hold at a few metres. The demonstration would allow for future missions to target no longer operational satellites and remove them from orbit, or even service them for reuse. Dutch company Isispace will manage the integration and in-orbit operation of three cubesats flying on Spectrum allowing a multitude of experiment providers to test and validate their technologies in space.
Developed at the DLR Institute of Space Systems in Bremen, PLUTO a 6U CubeSat technology demonstrator features breakthrough innovations: a 100W deployable solar array (1U stowed) and an Integrated Core Avionics system that brings large spacecraft capabilities to the CubeSat form factor.The mission validates critical technologies including software-defined radio, GaN power electronics and distributed computing. Our Unified Module Framework ensures seamless scalability from CubeSats to commercial satellites. PLUTO launches mid-2026 on Isar Aerospace's Spectrum rocket, followed by an advanced version PLUTO+ in 2027 on Vega Launcher.
27 Aug, 2025Isar Aerospace secures launch agreements with ESA Isar Aerospace becomes first privately funded player in Europe to sign commercial launch service agreements with ESA and the European Commission Contracts cover the launch of two missions aboard ‘Spectrum’ from 2026 onwardsMunich, 27 August 2025 – Isar Aerospace has secured two launch service agreements with the European Space Agency (ESA) and the European Commission as part of the Flight Ticket Initiative. The contracts mark the first launch agreements between a privately funded European launch service provider and European institutions, setting a precedent for future institutional launches aboard Isar Aerospace’s launch vehicle ‘Spectrum’.Daniel Metzler, CEO and Co-Founder of Isar Aerospace, said: “Isar Aerospace delivers sovereign space capabilities for Europe and its partners. These agreements demonstrate the trust European institutions have in our launch services. It marks a key step in strengthening Europe’s independent space access and sets the foundation for future institutional missions under other programs like the European Launcher Challenge.”The agreement covers the launch of two missions: The ‘CASSINI’ mission, developed by the Dutch company ISISpace, and the ‘Tom & Jerry’ mission by French company Infinite Orbits. Both missions will be launched from Isar Aerospace’s dedicated launch pad at Andøya Spaceport in Norway and are scheduled from 2026 onwards.The Flight Ticket Initiative, a joint program by the European Commission through Horizon Europe IOD-IOV and ESA’s Boost!, is designed to co-fund European launch services selected on a competitive basis to demonstrate and qualify in-orbit technologies.
Today, November 18, 2025, the German company Isar Aerospace announced a new launch service agreement with the US company SEOPS. The contract includes the delivery of multiple payloads to a LEO orbit as part of a mission set for 2028.AdvertisementDedicated missionSEOPS is a US-based company that provides launch services and integration solutions for small satellites to Low Earth Orbit, cislunar, and beyond.The company leverages its long flight heritage, with hundreds of delivered payloads and a 100% mission success rate, relying on flight-proven hardware platforms such as the Equalizer Flex and Ghost Trap CubeSat deployers. The recently introduced Keystone ring is capable of supporting payloads up to 850 kg, enabling smooth, low-shock deployment.The new agreement with Isar Aerospace will allow SEOPS to expand its Launchlock Prime service, which provides ongoing support for multiple custom missions such as constellation deployments.With its recent announcements, Isar Aerospace appears to be building a solid launch manifest for the coming years for the Spectrum rocket, supported both by ESA-backed missions and by demand from various private customers worldwide. The cadence of future launches will largely depend on the next few months, which will mark Isar’s return to launch operations from Andøya Spaceport in Norway.AdvertisementSpectrum toward orbitIsar Aerospace is developing Spectrum, a small-lift two-stage orbital rocket, capable of launching up to 1000 kg of payload into LEO. The rocket is powered by nine engines fueled with Propane and Oxygen....Nearly eight months later, on November 13, Isar announced that both the first and second rocket stages had been delivered from Germany to Norway for Spectrum Flight 2. There is still no information about a possible launch window date. In October, Andøya Space published a notice for potential road closures in the launch facility area during an operational period that will end on December 21.
Isar Aerospace wins launch contract for European tech demo satelliteby Jeff Foust December 2, 2025 WASHINGTON — German launch startup Isar Aerospace won a contract to launch a European technology demonstration satellite on its Spectrum rocket in late 2026.Isar Aerospace announced Dec. 1 that it will launch the mission, called ΣYNDEO-3, in the fourth quarter of 2026. The satellite is part of the European Union’s In-Orbit Demonstration and In-Orbit Validation (IOD/IOV) Program to flight-test new spacecraft technologies.For this mission, the spacecraft will carry 10 payloads from five European countries and the European Commission, but the announcement did not disclose details about the payloads. ESA implements to IOD/IOV program on the behalf of the Commission, with funding from the EU’s Horizon 2020 research program.The spacecraft is being built by Redwire Space’s European business unit, using its Hammerhead satellite bus based on the company’s work on ESA’s PROBA missions. The Hammerhead bus weighs 175 kilograms and can accommodate up to 120 kilograms of payloads.That comfortably fits into the payload capacity of Spectrum, which is designed to place up to one metric ton into orbit. A spokesperson for Isar said the launch contract is not for a dedicated launch, allowing Isar to fly additional payloads, but declined to disclose financial details of the award.The announcement of the ΣYNDEO-3 contract came less than two weeks after an American payload aggregator, SEOPS, announced it bought a Spectrum launch in 2028.“Our launch manifest is filling rapidly, as our global commercial and institutional customers recognize the value of flexible, cost-effective access to space,” Stella Guillen, chief commercial officer of Isar Aerospace, said in a statement about the ΣYNDEO-3 contract.Isar has performed one orbital launch attempt of Spectrum, in March, which malfunctioned seconds after liftoff. The company said in September that the rocket suffered a loss of attitude control after not properly characterizing bending modes it would experience at liftoff.At the time, Isar Aerospace said it was working towards a second Spectrum launch “as soon as possible” but did not give a date. The company has not provided updates since then on the schedule for the second launch that, like the first, will take place from Andøya Spaceport in northern Norway.“We are confident in the capability of Isar Aerospace to ensure a safe and reliable launch, bringing the mission to orbit very soon,” said Patrice Kerhousse, ESA’s IOD/IOV program manager, in a statement about the launch contract.
