High Performance Hybrid Upper Stage for NanoLaunch Vehicles

Parabilis Space Technologies, Inc (Parabilis), in collaboration with Utah State University (USU), proposes further development of a low-cost, high-performance launch vehicle upper stage that uses a high density, storable oxidizer and a polymer fuel grain as propellants in response to solicitation T1.01, Affordable Nano/Micro Launch Propulsion Stages. This effort will build upon the successful optimization studies, design, and testing activities completed during Phase I. The resulting technology will fulfill the ever-growing mission demands of the extensive CubeSat and NanoSat market by enabling dedicated launch for CubeSat scale payloads. Comparable launch vehicle stages in this size class are not currently commercially available. The proposed -green-propellant- system offers significant advantages over competing technologies in the areas of cost, safety, and mission capability.

This provides NASA a solution for low-cost payload insertion for in-house CubeSats offering a significantly higher degree of mission flexibility than is possible with rideshare delivery methods. The specific stage proposed for development in Phase II is ideally suited for integration with current NASA launch vehicle efforts. This stage will provide NASA the capability to expand programs for universities and research institutions such as the CubeSat Launch Initiative.

This provides a solution for low-cost payload insertion for commercial CubeSats offering a significantly higher degree of mission flexibility than is possible with rideshare delivery methods. Potential non-NASA customers include universities, small businesses, and research institutions. The proposed innovation is also an ideal solution to military responsive space challenges.

This is early/mid-stage (TRL 6) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
