Portal Space Raises $50M For Solar Propulsion

Innovative Vision Rooted In Aerospace Expertise

Jeff Thornburg, a former engineer at the U.S. Air Force and SpaceX, is developing propulsion systems at Portal Space Systems. The company was founded in 2021. Portal Space Systems raised $50 million in a Series A round, reaching a valuation of $250 million. Investors include Geodesic Capital, Mach33, Booz Allen Ventures, ARK Invest, AlleyCorp, and FUSE.

Revolutionizing Propulsion With Solar Thermal Technology

Solar thermal propulsion is being developed as an alternative to chemical and electric systems. Government laboratories have studied the concept since the 1960s. Concentrated solar energy is used to heat propellant, increasing thrust and maneuverability. Demand has grown alongside rising satellite deployments and defense-related requirements.

Strategic Investment And Military Interest

Portal Space Systems has received $45 million in funding linked to U.S. military programs, in addition to $67.5 million in private capital. Investors are evaluating applications in commercial satellite operations and defense scenarios, including spacecraft maneuverability in orbit.

Navigating The Path To Operational Flight

Portal is testing flight electronics in orbit and plans to launch a prototype spacecraft in October. A fully operational propulsion system is targeted for deployment by 2027 on the SuperNova spacecraft. The system includes a Hex thruster combining a solar concentrator and nozzle in a single unit.

Looking Beyond Today: Preparing For Future Propulsion Systems

Solar thermal propulsion is positioned as an alternative to nuclear systems, which face regulatory and technical constraints. In-orbit testing is being used to validate components, reducing reliance on ground-based infrastructure.

Industry Context

Demand for advanced propulsion systems continues to grow as satellite activity increases and orbital congestion expands. Portal Space Systems is developing technology focused on maneuverability, efficiency, and scalability in space operations.
