Benchmark Single Asset Kick Stage

For large orbit transfer logistics of the 25-200kg small spacecraft size range, Benchmark will combine our flight-proven high-test peroxide (HTP) bipropellant subsystem (Halcyon Avant), our multi-technology control electronics and SmartAIMTM propulsion control technology, a partner-supplied electric propulsion subsystem, and other commercial off-the-shelf (COTS) subsystems. The new development focus area will be to specify spacecraft interface and system design to maximize breadth of standard compatibility for a ‘universal fit’ across spacecraft and launch vehicles. The primary objective of the proposed phase I statement of work is to develop a preliminary design review (PDR) data package, to include subsystem requirement setting and selection, digital design package, and mission profile description. The PDR package will act as a gate into a phase II effort that would aim to bring the newly integrated system & platform architecture to a Technology Readiness Level (TRL) of 6, where an integrated transfer-stage system would be developed and readied for laboratory Hardware-in-Loop testing. Following the prospective phase II work, the transfer stage platform would be ready to enter a qualification and on orbit demonstration campaign. The value in having an in-space propulsion leader with multi-technology integrations, and orbit transfer mission experience is critical in maximizing pace and efficiency of a deployable solution to these long transfer challenges. A multi-mode or multi-technology solution provides the optimal maneuver capability; of which BSS has experience optimizing bulk impulse needs across multiple propulsion subsystems for advanced missions; which will be necessary to provide both the speed, endurance, and form factor required in a small spacecraft transfer stage (SSTS.) BSS will combine that expertise with COTS power, communications, and other vehicle subsystems to produce an SSTS platform.

Our proposal introduces Aquila, an independent transfer stage designed to support NASA’s diverse space exploration missions, particularly those extending beyond Low Earth Orbit (BLEO). With its initial design focus on Trans-Lunar Injection (TLI) missions, Aquila aligns with NASA’s solicitation requirements. However, its broader application encompasses high impulse, mass-optimized space mobility capabilities for enhancing the flexibility, reliability, and cost-effectiveness of payloads destined for cislunar, near-lunar, and beyond Earth orbit missions. Aquila’s launch vehicle agnostic design further facilitates mission manifesting flexibility and program resilience. Aquila's ability to operate independently marks a significant shift in deep space mission design, reducing the need for specific functions and subsystems traditionally required by NASA spacecraft. This allows NASA to focus more on unique payload values while utilizing a standard platform for all other essential subsystems and support functions. Furthermore, post-deployment, Aquila can serve as a free-flying adjunct spacecraft, performing roles such as a communications relay or a PNT node, thereby enhancing mission versatility, reliability, cost-effectiveness, and operational lifespan. In the broader context of the proposal, Aquila is developed with practicality and efficiency in mind, directly supporting NASA’s mission directives. Our technology leverages Benchmark Space Systems' extensive experience in propulsion systems and multi-technology integration, ensuring a robust and adaptable platform. Aquila’s innovative design, featuring a blend of chemical and electric propulsion systems and smart propulsion controls, aligns with NASA’s objectives for sustainable and scalable exploration tools. The system is poised to significantly advance NASA’s capabilities in space exploration, adhering to the agency's commitment to innovative and comprehensive space exploration. Commercial Sector - As referenced, Benchmark’s mission experience with LEO and GEO transfers, and lunar orbits have resulted in a relevant expertise and mission partner network to understand and identify space operators and mission primes who are looking for help with logistics of getting to these exotic and distant orbits. Benchmark’s commercial market targets for Aquila-SSTS are missions requiring in-space logistics to GEO and Lunar orbits. Benchmark has previously collaborated with Terran Orbital to develop a transfer stage concept aligned with their CAPSTONE mission profile, and has several Tier I engagements for GEO transfers ongoing. The fact that Benchmark hit a major mission milestone with Spacelfight’s Sherpa OTV combined with Spaceflight being acquired by Firefly who has chosen not to continue the Sherpa product line has led to an increase in inbound interest in Benchmark’s orbit transfer capability and solutions. Defense Sector - With an interest in sustainability and threat avoidance, the USSF has recent and open solicitations for autonomy including autonomous threat or collision avoidance. Rapid space logistics and autonomous dynamic operations platforms have been requested by our customers at AFRL’s propulsion branch, and referenced in recent Assured Access To Space (AATS) and Space Development Agency (SDA) solicitations. There are several programs and mission profiles that require improved and agile asset delivery to MEO, GEO, and Lunar domains that Aquila-SSTS would extend US capability for.

This is early/mid-stage (TRL 2) — 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.
