Objectives

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

Space science objectives are secondary
