Üks väiksemaid satelliite on Arizona osariigi ülikooli teadlaste poolt arendatud SunCube, mis kaalub vähem kui 100 grammi. Sellises kaalukategoorias satelliite nimetatakse femtosatelliitideks.
The community focus on miniaturization has been costly in our endeavor to do more with less. Femtosatellites, defined as having a mass less than 100 grams, turn this scenario on its head by forcing a do less with more mentality; individual spacecraft will be less capable, but coordinated operation of massively distributed femtosatellites can achieve the required overall mission capability. We believe that femtosatellites are the next “little thing” in the small satellite community that can restore research affordability, encourage revolutionary advances, and provide transformational mission capabilities.
Femto-satellites are a very promising new category of satellites with mass below 100 grams. At present there are no specific femto-sastellite launchers.
