Waypoints, week of 14 to 21 September 2026: European space capital breaks records as Ariane 6 stumbles

Open Cosmos closes €300 million round, largest European satellite raise of 2026

UK-based satellite maker Open Cosmos announced on 14 September that it had closed a €300 million funding round. The round was led by venture investors including UK-based Lightrock, ETF Partners and Entrepreneurs First, alongside Catalonia's public financial institution, Institut Català de Finances, with two unnamed international pension funds also among the lead investors. The €300 million raise represents the company's first major publicly announced funding round since September 2023, when it secured $50 million in Series B funding. The Monday announcement also drew backing from the UK's National Security Strategic Investment Fund. The company says its four European manufacturing facilities now have the combined capacity to produce one satellite per day, and it has secured more than $370 million in customer contracts over the past three and a half years. For founders: sovereign EO and secure comms are now investable at nine-figure ticket sizes, and public co-investors are actively anchoring rounds, worth structuring cap tables accordingly.

EnduroSat's $205M raise pushes September European NewSpace funding past €1 billion

Bulgarian satellite manufacturer EnduroSat has secured $205 million, roughly €178 million, in new funding, pushing the total raised by European NewSpace companies in September above €1 billion, in a round announced on 16 September and co-led by US investment firms Riot Ventures and Atreides Management, with participation from the European Innovation Council among others. It marks EnduroSat's second major funding round in less than a year, following a $104 million raise in October 2025. The capital will fund a new high-volume manufacturing facility in the United States and a significant European expansion, including plans announced on 6 August to transform the former Dobroslavtsi military airbase near Sofia into a major space and defence development and manufacturing hub. Alongside the round, EnduroSat won a contract to build 24 software-defined microsatellite platforms for Vantor, optimised for high-revisit imaging with modular payload integration and x-band communications. For ventures: transatlantic capital plus an EIC anchor is emerging as the template for CEE hardware scale-ups, and buyers are moving decisively toward standardised buses over bespoke builds.

ESA signs 18 Low-LEO IRIS2 contracts worth €20M with 80 companies, opens sandbox track

Signed on 17 September at the ESA European Space Astronomy Centre in Madrid, Spain, the agreements mark the start of a new phase of studies under the ESA Programme Related to EU Secure Connectivity. The European Space Agency awarded 18 contracts worth a combined €20 million to study potential future evolutions of the European Union's IRIS2 secure communications service, bringing together nearly 80 European companies, with applications in secure government broadband, maritime operations and aviation, data relaying and satellite tasking. The studies focus on the Low-LEO layer of the IRIS2 constellation, which will operate below approximately 750 kilometres, compared with the main IRIS2 LEO-High component at around 1,200 kilometres. ESA said the contracts are intended to give smaller and mid-sized companies opportunities to contribute, with resulting capabilities potentially supporting an evolution of the main EU IRIS2 system subject to future programme decisions. For founders: ESA has explicitly written SMEs into an IRIS2 sandbox pathway, D2D, IoT and drone connectivity concepts now have a formal on-ramp toward a €15.6 billion programme.

Ariane 6 turbopump anomaly caps 2026 manifest at six flights, down from a target of eight

The European Space Agency has confirmed that it is aware of delays affecting the Ariane 6 launch schedule following reports of an engine turbopump anomaly, first reported by French outlet La Tribune on 17 September. Reporting from Peter de Selding's Space Intel Report a day later identified the component as an engine turbopump, with the anomaly reportedly discovered during ground evaluations in August, and added that the issue could result in just one or two more Ariane 6 launches this year, rather than the three or four additional missions previously planned. Engineering teams from ArianeGroup and engine supplier Safran are evaluating whether corrective maintenance can be performed on-site at the Guiana Space Centre in Kourou, or if the affected hardware requires a complete turbopump replacement. ESA member states agreed in December 2024 to transfer responsibility for the oxygen turbopumps from Avio to ArianeGroup France, but the transfer has not yet been completed, with Avio continuing to produce the rocket's liquid oxygen turbopumps. For founders: European launch slots just got tighter as Avio also reports SpaceX-displaced demand, expect price and manifest pressure through H1 2027 for anyone integrating institutional payloads.

Denmark's Final Frontier and Myriad merge, target €100M Fund II for Nordic and Ukrainian defencetech

On 21 September, Danish defencetech VCs Final Frontier and Myriad joined forces to create a combined platform and move forward under one brand with a targeted €100 million fund. The fund is targeting €100 million for Final Frontier Fund II, which will back pre-seed and seed-stage defence tech startups across the New Nordics and Ukraine, with a first close expected by the end of the year. Final Frontier's first €4.5 million fund was closed in May 2025, supported by former NATO Secretary General Anders Fogh Rasmussen among others, while Myriad was a €2 million early-stage New Nordic defence fund launched in August 2025. The merged vehicle will back pre-seed and seed defence tech across the New Nordics and Ukraine, with founding partner Niels Vejrup Carlsen flagging equipment ruggedised for Arctic and maritime operations, sub-sea or surface, for all-weather conditions as a close focus. Individual ticket sizes at Myriad have historically sat between €100K and €500K for pre-seed and seed rounds. For founders: Nordic defencetech capital is consolidating into larger, institution-grade vehicles, arctic, maritime and counter-drone plays with Ukrainian battlefield validation now have a clear domestic buyer of early rounds.
