About
The Stand-Off Mechanism (SOM) is a passive deployable structure from MMA Space that separates payload elements from the spacecraft bus, deploying to a height of approximately 8 inches. Deployment energy is stored in folded tape springs, requiring no motors or active power at the moment of release — a Frangibolt assembly serves as the release mechanism, ensuring a single reliable actuation event. The SOM has confirmed flight heritage across MMA’s deployable structures portfolio.
