A dust astronomy mission aims at the simultaneous measurement of the origin and the chemical composition of individual dust grains in space. By distinguishing interstellar from interplanetary dust of cometary or asteroidal origin based on their trajectories and comparing their composition important clues on processes in the early solar system can be obtained. The dust observatory mission "Cosmic DUNE" has been defined to reach this goal with newly developed dust instrumentation. A dust trajectory sensor has been developed which is capable of obtaining precision trajectories of sub-micron sized particles in space. A new high mass resolution dust analyzer of 0.1 m^2 impact area can cope with the low fluxes expected in interplanetary space. With these instruments both novel dust measurements in low-Earth orbit and improved dust collection and sample return schemes are achievable.
