The three small cubes pictured here are #Cube #Satellites or "CubeSats”—miniature satellites whose compact size enables them to be launched straight from the International #Space Station rather than from the #Earth. This cuts costs and allows for cost-effective testing of #technologies and techniques that, once deemed successful, can be scaled up. The CubeSats pictured here are testing a high-speed transmission module and #aerospace vehicle electronics as well as capturing details like the Earth's #atmospheric changes and #magnetic field. #photooftheday #science #tech #ISS #internationalspacestation #orbit #nasa 📷 @NASA
