SmallSat Propulsion

Efficient. Affordable. Easy to use.

CometTM CubeSat and Microsatellite Propulsion System 

Comet is a simple, launch-safe, and cost-effective electrothermal propulsion system that uses water as a propellant and offers the ideal balance of cost and performance.

 

Great Performance

Comet boasts 80% of the specific impulse of hypergolic monopropellant systems, but at only 20% of their typical price. It also offers more thrust with less electrical power, allowing shorter maneuver times. This means your spacecraft can expend its valuable resources on operating the payload rather than the propulsion system.

Robust Operations

Using water as a propellant makes Comet easy to work with. Comet is already approved to ride on multiple launch vehicles as part of a secondary or rideshare spacecraft. The system was designed for ease of operations on orbit, meaning Comet will be easy to use, from the lab to orbit.

Easy Integration

Comet’s electronics make it easy to integrate and the design is scalable from CubeSats to small micro-satellites, with a highly-flexible interface suitable for a wide range of spacecraft. DSI’s team of small spacecraft experts will help customize Comet for your mission to make integration quick and simple.

Advantages

• Non-toxic; safe for humans and for launch vehicles

• Approved for flight on multiple launch vehicles

• 80% of monopropellant Isp, 20% of the cost

• More thrust with less electrical power than electric thrusters.

• Highly-flexible interface suitable for a wide range of spacecraft sizes

Shipping Now

Comet is a launch-safe and cost-effective electrothermal propulsion system that offers the ideal balance of cost and performance. This high-performance propulsion unit uses water as propellant, making the system easy to work with and easy to fuel. It’s highly-flexible interface is easy to integrate into your small satellite, regardless of size and form factor, and easy to operate on orbit. Comet has also been optimized for minimal power consumption and shorter maneuvering times, allowing you to focus more resources on your payload. Comet is currently in production and shipping to customers, with the first three units scheduled to launch in Q1 2018.
