The deliberate militarization of orbit: Europe asserts its independence under strain

This month, the global space sector crosses a historic and critical threshold, as the US military disclosed the deployment of offensive weapons in orbit, effectively formalizing the open militarization of space. In parallel, autonomous access to space is being redefined: the start-up Isar Aerospace achieved the first private orbital launch from continental European soil, while China is accelerating its reusable-launcher technologies, threatening American supremacy. In the face of this proliferation of satellites and debris, experts and regulators worldwide are sounding the alarm over orbital sustainability, even as the Paris space summit was marked by a boycott of American companies under political pressure.

The end of the taboos on the militarization and weaponization of Earth orbit

The domain of space security underwent a major doctrinal rupture on 14 September 2026. The US military officially revealed that it now possessed offensive weapons in space (Financial Times, 14/09). This unprecedented statement was corroborated by the secretary of the United States Air Force (USAF), Troy Meink, who acknowledged the operational deployment of attack capabilities in orbit (Airforce Technology, 25/09). The announcement has raised fears among experts worldwide of an uncontrolled arms race, prompting other space powers to accelerate their own orbital weapons programs in order to preserve the balance of power (Financial Times, 14/09).

Against this backdrop of preparation for multi-domain conflict, industrial alliances are forming rapidly. The Swedish defense giant Saab concluded strategic partnerships on 25 September 2026 with SSC Space, OHB Sweden and Ericsson to consolidate space defense capabilities and the integration of military networks (Airforce Technology, 25/09). On the regulatory front, the European Union (EU) is likewise adapting its legal instruments. Advocate General Ćapeta suggested on 24 September 2026 a broader interpretation of dual-use goods so as to fully incorporate the Union's strategic security concerns (EU Law Live, 24/09).

Europe asserts its independence through NewSpace despite geopolitical tensions

Independent access to space recorded a historic success on 5 September 2026 with the first successful orbital flight of the Spectrum rocket, designed by the German start-up Isar Aerospace (Süddeutsche Zeitung, 05/09; Le Monde, 06/09). Launched from the Norwegian spaceport at Andøya, this light launcher placed five satellites in low Earth orbit (The Guardian, 06/09). This success, described as "the beginning of a new era" by German chancellor Friedrich Merz (FAZ - Aktuell, 07/09), validates the viability of the private NewSpace model in breaking the de facto monopoly of American players such as SpaceX (Süddeutsche Zeitung, 06/09).

To consolidate this industrial autonomy, several major projects have been launched: * MaiaSpace (ArianeGroup): On 4 September 2026, construction of the factory for the first reusable launcher of the ArianeGroup subsidiary was officially begun in Vernon (Ouest-France, 04/09). * The Exploration Company (TEC): The European Space Agency (ESA) awarded on 10 September 2026 a major contract worth €760 million to the Franco-German start-up for the development of its Nyx cargo vessel under the Aladdin program (FAZ - Aktuell, 10/09).

Nevertheless, global competition remains fierce. An analysis by the Center for Security and Emerging Technology (CSET) published on 14 September 2026 warns of China's rapid advances in reusable launchers, which risk saturating the global market for low-cost constellations and contesting the superiority of the American industry (cset.georgetown.edu, 14/09). Moreover, geopolitical tensions are making their way into diplomatic circles: the first international space summit in Paris (9–10 September 2026) was the subject of a strict boycott by American companies (SpaceX, Blue Origin) under pressure from the Donald Trump administration, while China sent senior representatives (FAZ - Aktuell, 06/09).

Technological sovereignty: GPS-free navigation and sustainable space

In the face of jamming risks and cyber conflict, alternatives to the American-origin GPS system are becoming highly strategic. On 7 September 2026, the Pentagon's Defense Innovation Unit (DIU) announced the successful flight test of a quantum magnetic navigation system (MagNav) with Honeywell Aerospace, demonstrating an 89% improvement in accuracy over a four-hour flight without GPS signal over the Pacific (Airforce Technology, 07/09). In parallel, Thales reinforced its position in this sovereignty domain by acquiring Exail Technologies, the leader in autonomous GPS-free inertial navigation (Le Monde, 22/09).

On the scientific and environmental front, ESA carried out on 15 September 2026 the simultaneous launch from Kourou of the FLEX and Sentinel-3C satellites (FAZ - Aktuell, 15/09). Sentinel-3C reinforces the Copernicus Earth-observation program, whose data confirm an unprecedented global climate emergency: the Copernicus climate service revealed that August 2026 was the hottest ever measured worldwide (Daily Maverick, 10/09).

However, the exponential multiplication of satellites generates a direct threat of collision and pollution. ESA published on 25 September 2026 its annual report on the space environment, warning that long-term risks have increased tenfold owing to debris and mega-constellations (Süddeutsche Zeitung, 15/09; FAZ - Aktuell, 25/09). ESA director Josef Aschbacher is now urgently calling for binding space traffic rules at the international level (Süddeutsche Zeitung, 11/09).

To watch

• Miura 5 launch (PLD Space): Following ESA's revision of the timeline on 7 September 2026, the adjusted schedule for the test flight of the Spanish reusable launcher will be closely scrutinized by NewSpace market observers (Cinco Días, 07/09).
• AI chip test by Google: The experimental flight planned by Google aboard a SpaceX launcher to test the cosmic-radiation resistance of its Tensor Processing Unit (TPU) chips will mark a key milestone for in-orbit embedded computing (FAZ - Aktuell, 25/09).
• BepiColombo mission: ESA's exploration probe is entering its final approach phase toward Mercury after an eight-year journey (Cinco Días, 21/09).
• Spectrum allocation in South Africa: Following the revocation of the open wireless network by Minister Solly Malatsi, the Independent Communications Authority of South Africa (ICASA) is to proceed with direct spectrum allocations that will redefine the region's telecommunications landscape (Daily Maverick, 28/09).
