Adapting New Scale M3 Modules for Space Applications
New Scale Technologies offers a broad selection of linear and rotary M3 micro motion modules designed for high performance in demanding environments.
These commercial off-the-shelf (COTS) motion modules deliver precision and reliability across a wide range of terrestrial and industrial applications. They also provide a strong foundation for necessary adaptations for space environments with additional qualifications and customizations.
When COTS Modules Work in Space
Several spacecraft customers have successfully integrated COTS M3 modules after completing their own qualification work. These teams typically:
- Conducted specialized thermal and vacuum testing and conditioning
- Defined safe operating limits, including duty cycles
- Developed custom system-level designs with shielding, redundancy, or other protective features
This approach can be suitable for certain missions, but full space qualification requires additional customization depending on the specific spacecraft environment and mission profile.
Considerations for Space Qualification
Vacuum Compatibility
To meet outgassing requirements, some materials may need to be replaced or re-engineered. NASA guidelines often necessitate changes in lubricants, polymers, and mechanical design details to ensure performance in vacuum conditions.
Temperature Extremes
Standard COTS specifications are:
- Storage: –40 °C to +85 °C
- Operating: –30 °C to +70 °C
Motion performance and duty cycle can degrade near these limits. Applications outside these ranges require custom designs and qualification testing to maintain performance.
Shock and Vibration
COTS modules include published maximum load ratings appropriate for many mission conditions. With proper system design and optional mechanical reinforcement, such as launch latching mechanisms, they can be qualified to perform reliably even under extreme launch environments.
Radiation Hardening
Radiation primarily impacts electronic components, particularly on longer or higher-altitude missions. M3 modules, embedded with digital electronics, use CE-tested commercial-grade ICs and feature mechanical and piezoelectric components that are generally robust to radiation.
Enhanced configurations for higher-radiation missions may include:
- Radiation-hardened ICs
- Class 3 PCBs with conformal coating
- Added shielding for long-duration operation
Partnering for Success in Space
Several spacecraft teams have successfully integrated COTS M3 modules after completing their own qualification work:
- Conducting thermal and vacuum testing
- Defining safe operating limits
- Developing protective system designs with shielding or redundancy
While our COTS M3 modules deliver proven precision and compact performance, full space qualification often requires collaborative customization to match the specific spacecraft environment and mission profile.
