AI-summarised brief · reviewed before publication

Stellar Alpina, a Zurich-based SpaceTech startup, has secured €3.8 million in a pre-Seed funding round to develop compact rotating detonation rocket engines (RDREs) for in-space mobility. The startup aims to make movement between orbits faster, smaller, and more efficient. Founded in 2026, Stellar Alpina was born from the Academic Spaceflight Initiative Switzerland, where the co-founders developed the world's first student-built RDRE in 2024. The company is tackling the challenge of in-space mobility, where existing systems are outdated and unable to meet the growing demands of the space economy.

💡 Why It Matters

· A reliable and efficient in-space mobility system is crucial for the success of lunar programs, such as NASA's Artemis, and the European Space Agency's exploration roadmap.
· The ability to transfer and land payloads in space will also be essential for in-space servicing and manufacturing, which are moving from concept to procurement.

Governor Shapiro Announces $30 Million Investment from Nokia

Governor Josh Shapiro announced a $30 million investment from Nokia to expand its photonic semiconductor operations in Lehigh County, creating over 250 new jobs and retaining 308 positions. The project will nearly double Nokia's Pennsylvania workforce and generate a $500 million economic impact over five years. The Commonwealth is investing over $3 million in the project, which will expand Nokia's existing operations by up to ten times. This growth reinforces Pennsylvania's role as a hub for advanced semiconductor production, used in broadband networks and fiber optic systems. Nokia's investment is crucial in growing the Lehigh Valley's role in global supply chains.

💡 Nokia's investment fills a critical gap in US semiconductor production, where less than two percent of global capacity is currently located. Pennsylvania's supportive business climate is helping the state compete on a global scale in innovation and advanced manufacturing.

SpaceX alum nabs $22M to turn rocket engines into geothermal power plants

Critical Energy, a startup founded by SpaceX alum Spencer Jackson, has raised $22 million to develop modular turbines for geothermal power plants. The company aims to fill a gap in the market by providing turbines tailored to geothermal power plants, with the funds earmarked to build its first 2.5 megawatt project. Geothermal energy has significant potential, with at least 42 terawatts of capacity available worldwide, and Critical Energy hopes to play a key role in its development. The startup's modular turbines are designed to be built in a factory, reducing assembly time and costs. The first power plant using Critical Energy's turbines is scheduled for completion by 2027.

💡 Geothermal energy could beat nuclear fission and fusion to commercial deployment, with Critical Energy's modular turbines potentially enabling gigawatt-scale power plants by the early 2030s. Advanced geothermal could also power nearly two-thirds of new data centers by 2030, addressing the tech industry's growing energy needs.

Pramaana Labs raises $27M seed round from Khosla Ventures to bring formal…

Pramaana Labs has announced a $27 million seed funding round led by Khosla Ventures, with participation from several other investors. The startup aims to bring formal verification to AI, focusing on sensitive verticals like law, drug discovery, and tax preparation where errors can be costly. Pramaana's system combines a conventional large language model with a deterministic layer, using the open-source LEAN programming language to verify mathematical proofs. The company will build formal verification systems for each use case, overseen by domain experts, to ensure reliability and accuracy in AI deployments. This approach draws on the tools of mathematical formalization.

💡 By codifying rules and regulations into executable code, Pramaana Labs can provide stronger protections against AI errors and hallucinations. This deterministic approach can ensure that AI decisions are reliable and trustworthy, especially in high-stakes domains.
