The most versatile product family in our portfolio, Halcyon non-toxic ('green') propulsion systems are offered in a monopropellant or dual-mode bipropellant architecture with flexible thruster and tank configuration to serve a range of spacecraft and mission requirements.
Halcyon systems are designed to eliminate cost and lead-time driving materials that commonly challenge catalyst beds and thrusters in high-thrust chemical systems without compromising performance or reliability.
Products
Benchmark designs and builds turn-key propulsion systems for cubesat through ESPA and OTV class spacecraft in LEO, GEO, and beyond. Our core focus is to eliminate pain points in propulsion procurement and integration, enabled by a range of non-toxic propellants, qualified subsystems including thrusters, propellant tanks, modular control electronics, and intelligent GNC integration framework. What you will get is a plug-and-play system optimized to deliver a best-in-class solution to meet your operational and commercial mission objectives. What you won't get is a misaligned or inadequate solution to your problem. If Benchmark's vast solution set cannot close out the desired mission outcomes, we will work candidly to recommend alternatives.
Halcyon Chemical Propulsion Systems

The highlight of the Halcyon product lineup is our proprietary dual-mode thruster that features a post-catalyst fuel injection technology for missions that demand the highest specific impulse on the market.
Operations in bipropellant mode can deliver more than 300s specific impulse, while monopropellant (HTP-only) mode provides excellent impulse bit performance for precision operations.

Whether your goal is to maximize revenue, perform rapid and advanced maneuvers, or provide complimentary capability to a low-thrust system - there's a 'right-sized' Halcyon solution for your mission.
Halcyon systems are optimized for your spacecraft (6U-ESPA), total impulse (1kN·s-200kN·s), control authority (1-12 thrusters), and radiation environment (LEO, GEO, Cislunar). Contact our team to unlock the widest range of on-orbit operations available from any single in-space propulsion provider on the market.

In June 2021, 3 Halcyon systems launched aboard the SpaceX Transporter 2 rideshare mission. All 3 units were equipped with Benchmark's ODPS™ (On-Demand Pressurization System) and one debuted Orbit Fab’s RAFTI refueling kit as part of their Tenzing mission, the first fueling depot in LEO.

Xantus Metal Plasma Thruster
Xantus metal plasma thrusters are optimized for cubesats, and an integral tool for microsat mission optimization with high-endurance station keeping and ultra-precise pointing and docking operations.
Benchmark’s technology and product roadmap leads to a prominent role in future On-Orbit Servicing, Assembly and Manufacturing (OSAM) operations, where the MPT technology will support in-space proximity and docking operations. Our Halcyon + Xantus hybrid packages will be engineered to ultimately incorporate in-space resource utilization (ISRU) techniques to enable a sustainable space ecosystem.

Benchmark's differentiated millinewton-class Electric Propulsion system offers the highest total impulse in its size and several unique operational attributes, including a simple power and control unit, precise impulse bits, and modular design with a wide operational range.
The 5 kN∙s per 1/2U package, can be combined with additional MPT or Chemical thrusters.
Xantus Metal Plasma Thruster does not utilize gas or liquid propellants, neutralizers, heaters or high voltage electronics.
Download our data sheet for additional technical specifications.

The Xantus metal plasma thrusters, which can single-handedly address most cubesat missions, provide high-endurance for station keeping, and mission extension, and ultra-precise impulse bits for pointing operations.
In hybrid format, the MPT + Chemical Propulsion system addresses a wide range of operational needs and increase ROI without compromising speed and endurance.

The Metal Plasma Thruster was developed by Alameda Applied Sciences Corporation over the span of a decade. With consistent NASA support along the way, variations of plasma physics and system architecture has led to a flight-ready system, manifested on a heritage USSF Demonstration (RROCI) mission in 2022, with an upcoming radiation hardened configuration being prepared for full qualification
Starling Cold Gas Systems
The Starling line of gas propulsion systems is designed with unprecedented safety and configurability in its class. With a variety of propellant options that include an unpressurized-launch variant and a patented resistojet option, Starling is an ideal choice for operation sets that require a simple and reliable solution and no more than 2kN·s total impulse.

The patented technologies that differentiate the Starling offering from other gas systems is the ODPS™ (On-Demand Pressurization System) and resistojet design.
ODPS™ utilizes a non-toxic powdered propellant that is inert and DOT-approved for shipping and can be pressurized on-orbit with as little as 15W of power.
Benchmark's resistojet is the result of design iterations across multiple NASA-funded programs to maximize efficiency and double the specific impulse of a typical gas system (from 70s to 140s.)

The game-changing ability to be 'fueled', shipped and stored fully assembled simplifies spacecraft integration and launch manifest logistics, improving safety and providing a path to ISS compatibility.
Gas systems can be excellent options for smaller spacecraft or budget-limited missions, or for larger spacecraft that can benefit from mission assurance provided by supplemental or off-nominal operational coverage.

The ODPS™ has earned flight heritage as a subsystem, and several Starling Ardent systems are planned for launch in 2023.

Peregrine Hypergolic Systems
Benchmark's Peregrine offering is an HTP-based hypergolic propulsion system that makes use of the propellant management and control electronics components and subsystems used in the flagship Halcyon product line.
Contact our team to help qualify if a Peregrine system is right for your mission.

Benchmark's patented micro-mixing technique combined with (legacy) Tesseract's larger scale developments provide the experience needed to configure systems from 250mN to 500N.
Similar to the Halcyon systems, this HTP and Alcohol-fueled technology can sustain long burn durations without requiring sophisticated or active thermal management systems.

Peregrine systems are ideal for high-thrust operational requirements that include relatively long burn durations (>10 minutes) or high propellant throughput (>10,000 seconds) and do not require stringent impulse-bit performance.
Hypergolic system solutions are best utilized for missions that depend on a significant insertion or transfer maneuver.

The Peregrine systems have been developed and demonstrated to TRL6 in our labs with R&D funding. Due to spacecraft and mission specificity, Benchmark plans to identify a customer's or partner's requirement set to configure our first in-space system.

Thruster Configurations
Although the majority of our customers are looking for a mobility partner that will support their missions with an integrated and optimized propulsion system and associated services - we do offer thrusters for integrators that have experience managing their own design and are looking to complete or upgrade their systems.
Contact our team to explore our growing list of qualified and heritage products.

Benchmark offers resistojet, catalyzed HTP monopropellant, catalyzed (dual-mode) HTP + Fuel bipropellant, and Hypergollic thrusters ranging from 50mN through 500N.
Contact our team to explore our growing list of qualified and heritage products.

Benchmark offers thrusters as stand-alone components or packaged with our valves and driving electronics and will work with our customers and partners to maximize the benefits of our technology and expertise and ensure your mission gets the capability, cost, and lead time benefits that our thrusters offer.

Benchmark has heritage on our 1N catalyzed HTP monopropellant thrusters, and has several additional configurations and sizes qualified and scheduled for debut missions (100mN resistojet, 250mN monopropellant, 2N Dual-mode, 22N Dual-mode, 22N ASCENT.)
