About
Morpheus Space is a space propulsion company offering the GO-2 FEEP-based electric propulsion system—purpose-built for the new generation of small and nano satellites. The GO-2 delivers a total thrust range of 5 µN to 400 µN and an optimal total impulse range of 12.4 kNs to 6.2 kNs, all within a compact ~1U footprint (113 × 98 mm²) drawing just 7–40 W of power. Built around three generations of flight-proven technology—with core hardware in orbit since 2018 and commercial customer missions supported since 2023—GO-2 executed the world's first nanosatellite collision avoidance maneuver. The solid metallic propellant eliminates leakage, moving parts, chemicals, and pressurization concerns, making integration straightforward. Each unit contains 40 independent thrusters, each with its own propellant tank and thrust controller, delivering an exceptional level of redundancy and precision. Morpheus Space also provides the GO-2 Estimator, an online tool that helps mission planners quickly calculate how many GO-2 units their satellite requires for optimal performance. GO-2 is ideally suited for constellation operators, satellite integrators, and NewSpace startups that require a reliable, modular, and cost-effective propulsion solution for 6U and larger spacecraft.
Key Features
- 40 Individually Controlled Thrusters: Each GO-2 unit contains 40 independent thrusters with dedicated propellant tanks and thrust control, enabling precise maneuvering and an unprecedented level of redundancy.
- Solid Metallic Propellant: Utilizes a solid metallic propellant with zero leakage risk, no moving parts, no hazardous chemicals, and no pressurization required—simplifying integration and storage.
- Plug & Play 1U Form Factor: Compact ~1U module (113 × 98 mm²) designed for easy integration into spacecraft from 6U and up, removing the complexity of traditional propulsion system integration.
- GO-2 Estimator Tool: An online estimator lets mission planners quickly determine the number of GO-2 units needed to meet their satellite's maneuver and lifetime requirements.
- Flight-Proven Heritage: Core technology has been in orbit since 2018, with commercial missions supported since 2023, including the world's first nanosatellite collision avoidance maneuver.
Use Cases
- Constellation deployment and slot management for small satellite operators requiring precise orbital placement and spacing.
- Station keeping for satellites in LEO, MEO, or GEO that need to maintain their designated orbit against atmospheric drag or gravitational perturbations.
- Collision avoidance maneuvers to respond to conjunction alerts and reduce the risk of on-orbit debris generation.
- End-of-life deorbit compliance, enabling satellite operators to meet regulatory requirements for responsible disposal of spacecraft.
- Technology demonstration missions for universities and NewSpace startups testing novel payloads that require on-orbit repositioning or controlled re-entry.
Pros
- High Redundancy & Reliability: 40 independent thruster modules mean a single point failure has minimal impact on overall system performance, maximizing mission uptime.
- Safe & Easy to Handle: Solid metallic propellant eliminates the hazards of liquid or pressurized propellants, simplifying ground handling, shipping, and satellite integration.
- Scalable Across Mission Types: Supports constellation deployment, station keeping, collision avoidance, and deorbit in a single modular unit compatible with a wide range of spacecraft sizes.
- Flight-Proven Technology: Three generations of in-orbit heritage with commercial missions ongoing since 2023 provide strong confidence in performance and longevity.
Cons
- Limited to Nano/Micro Satellite Class: The GO-2's thrust range (5–400 µN) is optimized for small satellites (6U+); larger spacecraft requiring higher thrust levels would need alternative propulsion solutions.
- Pricing Not Publicly Listed: As a B2B aerospace hardware product, pricing and availability require direct engagement with the Morpheus Space sales team, which may slow early-stage planning.
- Low Total Impulse for High-Delta-V Missions: The maximum total impulse of 12.4 kNs may be insufficient for missions requiring extensive orbital changes or very long operational lifetimes without multiple units.
Frequently Asked Questions
What spacecraft sizes is the GO-2 compatible with?
The GO-2 is designed for spacecraft from 6U CubeSats and up. Its modular ~1U footprint allows it to scale with the mission by stacking multiple units for higher impulse requirements.
What propellant does the GO-2 use?
GO-2 uses a solid metallic propellant (indium-based FEEP technology). This eliminates leakage risk, pressurization requirements, and hazardous chemical handling, making ground operations straightforward.
How do I determine how many GO-2 units my satellite needs?
Morpheus Space provides an online GO-2 Estimator tool. By entering your mission parameters, it quickly calculates the optimal number of GO-2 units required for your satellite's maneuver budget and lifetime goals.
What maneuvers can the GO-2 support?
The GO-2 supports the full range of on-orbit maneuvers including constellation deployment, orbit raising and lowering, station keeping, collision avoidance, and end-of-life deorbiting.
Has GO-2 been tested in space?
Yes. Morpheus Space's core FEEP technology has been in orbit since 2018 and has supported commercial customer missions since 2023. It also executed the world's first in-space nanosatellite collision avoidance maneuver.
