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.

In September 2022, our Halcyon Avant with four 22N bipropellant thrusters was launched to propel Spaceflight's Sherpa-LTC 2.

Based on Benchmark’s 1N HTP thruster, propellant tank, and electronics with heritage, the COLA Kit is configured as a low-frills blowdown system to meet required cost and reliability objectives. The Kit is available in either a modular or integrated architecture for broad application, and comes with standard electrical and mechanical interfaces. 

The COLA Kit is right-sized for microsatellites and ESPA class spacecraft, to deliver several to dozens of unplanned maneuvers. As space traffic, debris, and other on-orbit activity threaten the commercial space ecosystem - rapid maneuverability for effective late-warning conjunction avoidance will play a critical role in enhancing space sustainability and regulatory preparedness. 

The COLA Kit is based on Benchmark’s 1N HTP thruster, propellant tank, and electronics with flight-heritage. With high demand for stand-alone COLA Kits and bundled partner solutions, we anticipate heritage missions as soon as 2023. 

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.

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 led to a flight-ready system, with an upcoming radiation hardened configuration being prepared for full qualification.

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.

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.

Benchmark offers resistojet, catalyzed HTP monopropellant, catalyzed (dual-mode) HTP + Fuel bipropellant, and Hypergollic thrusters ranging from 50mN through 500N.

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.
