Waypoints, week of 1 September 2026: Isar reaches orbit, Kyiv taps €90bn loan, HyImpulse extends Series A

Isar Aerospace reaches orbit on Spectrum's second flight, clearing the first ESA European Launcher Challenge gate

German company Isar Aerospace successfully reached orbit with its Spectrum launcher on 5 September, lifting off from Andøya Spaceport in Norway at 22:12 CEST. The mission deployed five CubeSats into low Earth orbit and marked the first time a privately funded European orbital rocket had reached orbit, and the first successful orbital launch from continental Europe. Spectrum is 28 m tall, 2 m in diameter and, with its ten engines, targets payloads of up to 1000 kg to LEO. The European Launcher Challenge requires launch service providers to achieve an orbital flight no later than 2027, and this mission makes Isar the first provider to reach that milestone. In August, Isar signed a contract worth €200 million with ESA under the Challenge. For ventures: a sovereign European ride to LEO now exists on paper and in metal, tightening the case for EU anchored payload, bus and ground segment roadmaps priced against Ariane 6 and Vega C rather than SpaceX alone.

Ukraine asks Brussels to exempt US-built PAC-3s from the €90bn loan's 35% non-EU content cap

The European Union is reviewing Kyiv's request to spend billions of euros on PAC-3 interceptor missiles for its Patriot batteries, the first time Ukraine has formally asked to tap a €90 billion support loan approved earlier this year to buy the US-made systems. Commission President Ursula von der Leyen confirmed the request on X on 2 September, alongside NATO Secretary General Mark Rutte. The loan's rules were written to prioritise European and Ukrainian-made weapons, capping non-EU and non-Ukrainian content at 35% of a given purchase's value, so because PAC-3s are built in the US, Kyiv's request needs a formal exemption. Ukraine already secured a similar carve-out in April for Chinese-made drone components, a precedent officials are pointing to. For founders: the 35% rule is the door European suppliers have been asking for, and every exemption granted narrows the addressable share of that €90 billion. If your air defence, interceptor or C-UAS stack can plausibly be classified as EU or Ukrainian content, now is the moment to get onto framework lists.

Munich's Project-S exits stealth with multi-million euro seed to hunt 1 to 10 cm debris in LEO

Munich based space situational awareness startup Project-S has emerged from stealth with what it describes as 'multi-million-euro backing', and is preparing for the first in-orbit demonstration of its active radar aboard a SpaceX Transporter rideshare mission next month. On 2 September, Project-S publicly revealed plans to develop systems capable of detecting smaller orbital threats and modelling their paths to 'support safer satellite operations', with a funding round led by Greek venture capital fund Uni.Fund II, supplemented by non-dilutive support from the German government and ESA linked public innovation programmes. ESA's latest annual Space Environment Report estimates around 54,000 objects larger than 10 cm orbiting Earth, 1.2 million objects between 1 and 10 cm, and 120 million between 1 mm and 1 cm, and Project-S is targeting the 1 to 10 cm band that current ground radar largely misses. For founders: SSA is quietly turning from a public good pitch into a commercial subscription market, with a Greek fund leading a German radar startup on the strength of ESA co-financing. Cross border syndicates plus non-dilutive top-ups are becoming the default seed structure for European dual use hardware.
