Spain Funds Next-Gen Aerospike Rocket Engine to Boost EU Space Sovereignty
Pangea Aerospace secures €7.27M to develop reusable ARCOS engine with 3D-printed tech, aiming to transform Europe’s launch capabilities by 2027.

Spain Bets Big on Next-Gen Rocket Technology
European space engineering reaches a critical milestone as Pangea Aerospace secures €7.27 million through Spain’s Space Technology Programme. This funding fuels development of the ARCOS aerospike engine – a technological leap that could reshape orbital launch economics. Unlike conventional rocket engines, aerospike designs maintain optimal efficiency across altitudes, potentially reducing fuel consumption by 30% while enabling full reusability.
The investment comes amid growing European urgency to develop sovereign space capabilities. With SpaceX dominating reusable launch systems and geopolitical tensions affecting international collaboration, Spain’s CDTI innovation agency has prioritized 24 strategic projects through its PERTE Aerospace initiative. Pangea’s engine project represents the second-largest allocation in this €70 million funding round.
The MERLIn Consortium: Collaborative Innovation
Pangea leads a powerhouse consortium including ITP Aero (propulsion experts), Sener (control systems), and Aenium Engineering (additive manufacturing). The partners will pool expertise to overcome aerospike’s historic challenges – complex cooling requirements and manufacturing precision. ITP Aero brings decades of jet engine experience from Airbus programs, while Sener contributes flight-proven thrust vectoring systems used in ESA missions.
Financial breakdown reveals strategic priorities: €3.9 million directly funds Pangea’s engine development, with remaining allocations supporting complementary technologies. This structure ensures vertical integration – from advanced nickel superalloys to AI-driven combustion modeling. The consortium approach mirrors successful models like Airbus’s distributed manufacturing, but adapted for NewSpace agility.
“We’re solving thermal management puzzles that baffled NASA in the 1990s,” says Xavier Llairó, Pangea’s CCO. “Our additive manufacturing breakthroughs let us create cooling channels impossible with traditional machining.”
ARCOS Engine: Technical Breakthroughs
The 750kN methane-oxygen engine targets medium/heavy lift upper stages, addressing a critical gap in Europe’s launch portfolio. Key innovations include:
- 3D-printed combustion chambers with fractal cooling channels
- AI-optimized injector patterns reducing combustion instability
- Modular design allowing thrust scaling from 300-700kN
Compared to Arianespace’s Vinci engine, ARCOS offers 15% greater specific impulse during upper-stage operation. This efficiency gain could translate to 2+ tons of additional payload on Ariane 6-class missions. The methalox propellant choice future-proofs the design, aligning with ESA’s Prometheus engine roadmap and enabling Mars return missions through in-situ resource utilization.
Reusability features are particularly revolutionary. Traditional upper stages burn up on reentry, but ARCOS enables controlled return via integrated thermal protection and restart capabilities. Pangea’s 2021 Demo-P1 test article achieved 12 ignitions during a single test campaign – crucial for proving rapid turnaround potential.
European Space Sovereignty at Stake
This project arrives as Europe’s share of global launches drops below 4%. With SpaceX completing 96 missions in 2024 and China’s commercial sector accelerating, EU states recognize the strategic necessity of reusable systems. Spain’s investment signals a policy shift towards nurturing homegrown NewSpace firms rather than relying on legacy contractors.
Industry analysts note Pangea’s €23 million Series A funding (led by Hyperion Fund) positions it as Europe’s answer to SpaceX’s Merlin engines. However, scaling requires infrastructure: the company plans to double its workforce to 140 and establish dedicated test facilities in Teruel by 2026.
“Aerospike isn’t just about better engines,” observes former ArianeGroup CEO André-Hubert Roussel. “It’s about reclaiming European autonomy in an era where space infrastructure equals geopolitical power.”
Conclusion
The ARCOS development marks a watershed for European space capabilities. By solving aerospike’s historical challenges through modern manufacturing and materials science, Pangea’s consortium could slash launch costs while increasing payload capacity – critical for competing in the $1.8 trillion space economy.
Success hinges on sustained funding and regulatory support. With Germany’s ISAR Aerospace and Spain’s PLD Space preparing inaugural launches, Europe’s commercial space ecosystem is finally coalescing. The coming decade will determine whether these efforts can close the gap with US and Asian competitors.

NASA Names Artemis III Crew for 2027 Earth-Orbit Test Flight
NASA has assigned four prime crew members for Artemis III, a 2027 orbital mission to test commercial lunar lander docking ahead of Artemis IV.

The National Aeronautics and Space Administration (NASA) has named the four prime crew members and one backup for the Artemis III mission, a 2027 Earth-orbit test flight designed to demonstrate rendezvous and docking capabilities with commercial human landing systems.
In a press release issued on June 9, 2026, the agency confirmed the mission will serve as a prerequisite for Artemis IV, which is targeted as the first crewed mission to the lunar South Pole in 2028. The Artemis III profile focuses on orbital operations, testing the SpaceX Starship and Blue Origin Blue Moon landers in low Earth orbit following the successful completion of the Artemis II circumlunar flight in April 2026.
Crew assignments and international partnership
NASA astronaut Randy Bresnik will command the mission, joined by NASA mission specialists Andre Douglas and Frank Rubio. Rubio previously completed a record-breaking 371-day single spaceflight. European Space Agency (ESA) astronaut Luca Parmitano will serve as pilot, marking the first time an ESA astronaut has been assigned to an Artemis flight. NASA astronaut Bob Hines is designated as the backup crew member.
“Artemis III will push the boundaries of spacecraft operations in orbit. Luca’s assignment as pilot reflects the depth of European expertise in human spaceflight and draws on his extensive operational experience in high-pressure situations,” ESA Director General Josef Aschbacher stated.
NASA Administrator Jared Isaacman noted that the mission will test complex rendezvous and docking operations while advancing technologies required for deeper solar system exploration.
Mission profile and hardware integration
The Artemis III flight plan outlines a two-week mission in low Earth orbit. The crew will launch from Kennedy Space Center in Florida aboard the Orion spacecraft, propelled by the Space Launch System (SLS) rocket.
Once in orbit, the Orion spacecraft will conduct separate docking operations with two commercial lander test articles. The crew will spend approximately two days docked with the Blue Origin lander and one day docked with the SpaceX Starship pathfinder. The mission will conclude with a splashdown and U.S. Navy recovery in the Pacific Ocean.
Preparation for the flight is advancing. During the summer of 2026, engineers are scheduled to connect the Orion crew and service modules and integrate the docking system. Simultaneously, SLS rocket stacking and the installation of four RS-25 engines will begin at Kennedy Space Center.
AirPro News analysis
We note that the Artemis III mission profile represents a pragmatic adjustment in the lunar exploration timeline. By converting Artemis III into an Earth-orbit test flight, NASA mitigates the risk associated with deploying untested commercial landing systems directly to the lunar environment. This orbital checkout of the SpaceX and Blue Origin hardware ensures that critical rendezvous and docking procedures are validated before the Artemis IV mission attempts a lunar South Pole landing in 2028. The inclusion of an ESA pilot also solidifies the international framework required for sustained lunar surface operations.

Isar Aerospace Raises EUR 270M to Scale Spectrum Launch Vehicle
Isar Aerospace secured EUR 270M in Series D funding to produce up to 40 Spectrum rockets annually and expand sovereign launch access.

Isar Aerospace secured EUR 270 million in Series D funding on June 9, 2026, to scale production of its Spectrum launch vehicle and address a critical gap in European sovereign space access.
The funding round, backed by new investors Island Green Capital and Molten Ventures alongside the NATO Innovation Fund, arrives as the Munich-based manufacturers prepares for the second flight of its Spectrum rocket. According to a company press release, the capital will support the expansion of global operations and the serial production of up to 40 launch vehicles annually at its Parsdorf facility.
Strategic shift toward defense and sovereign capability
Isar Aerospace reported that its demand profile has shifted significantly over the past 12 months, with 60 percent of its backlog now defense-related. This aligns with broader regional security initiatives. In May 2026, the SPARTA 2.0 report identified sovereign European access to space as a central capability gap.
The company noted that Europe conducted fewer than 10 orbital launches in 2025, compared to more than 190 by the United States. The inclusion of the NATO Innovation Fund in this funding round underscores the strategic importance of independent orbital access for member nations.
Daniel Metzler, Co-Founder and CEO of Isar Aerospace, emphasized the geopolitical stakes in the press release.
Space is no longer a frontier; it is the infrastructure of national power. With this strategic backing, we are expanding access to space for nations worldwide, delivering an orbital launch system at scale for government and commercial customers.
Spectrum launch vehicle development and upcoming flight
The funding announcement precedes the scheduled qualification flight of the Spectrum launch vehicle, designated Mission ‘Onward and Upward’. The launch window is set for June 15 through June 21, 2026, from the company’s launch site in Andøya, Norway. The vehicle, designed to carry up to 1,000 kilograms to low Earth orbit, will carry five CubeSats on this mission.
This upcoming flight represents the second launch attempt for the Spectrum program. The inaugural flight in March 2025 ended in failure less than a minute after liftoff. Subsequent attempts in early 2026 faced delays. A March 25, 2026, attempt was scrubbed due to an unauthorized vessel entering the designated danger zone, and an April 9, 2026, attempt was halted after operators discovered a leak in a composite overwrapped pressure vessel.
Global expansion and infrastructure
Beyond its Norwegian launch site, Isar Aerospace is expanding its operational footprint. The company signed a Letter of Intent with Maritime Launch Services to establish Spaceport Nova Scotia as a second launch site, which will facilitate missions to mid-inclination and high-inclination orbits. The manufacturer also entered a cooperation agreement with TKMS for the Canadian Patrol Submarine Project, integrating sovereign launch capabilities within a NATO bilateral defense procurement framework.
AirPro News analysis
We view Isar Aerospace’s successful EUR 270 million raise as a strong indicator that institutional and defense investors are prioritizing assured access to space over immediate commercial returns. The shift to a 60 percent defense-oriented backlog reflects a broader European realization that reliance on foreign launch providers presents an unacceptable strategic vulnerability. While the Spectrum vehicle’s development has encountered typical aerospace hurdles, including the March 2025 failure and recent scrubs, the backing of the NATO Innovation Fund suggests high confidence in the engineering path forward. The upcoming June 2026 launch window will be a critical technical milestone to validate this substantial financial backing.
