Teeny Tiny Itty Bitty Spacecraft
‘Smart dust’ to explore planets, BBC
“Tiny “smart” devices that can be borne on the wind like dust particles could be carried in space probes to explore other planets, UK engineers say. The devices would consist of a computer chip covered by a plastic sheath that can change shape when a voltage is applied, enabling it to be steered. Details were presented at the National Astronomy Meeting in Preston.”
