Qualify micro and nanotechnology components Major step forward in the technical development of instrumentation for space science research.Qualify new sensors and boom systemsShrinking the electronics is not sufficient, sensors and boom systems must also follow suit.Test and verify new measurement methodsNew questions in space science, inspires the need to find new measurement methods. ObjectivesJan BergmanSpace science objectives are secondary
