Often people associate small with being frail. But our tiny shutters, which don't touch when they close, are exceptionally strong, especially when operating in space where there's no gravity, weight or resistance forces to wear or degrade moving parts. |
This is the first time a fully space-qualified device of this type has ever been flown, and the first to be flown on the outside of a satellite. |
When the satellite is facing the sun, for example, you could cool it by closing our shutter doors and reflecting the heat. Or if you need to absorb more heat, the shutters would open. |
