Right now there is a press conference sharing information about an undertaking which is sending nano-crafts for lightwindtraveling. These objects are based on a wafer containing all necessary tools for traveling and research as well as a lightsail. The missions target is Alfa Centauri.

Quite interessting to learn about this whilst we are also learning about crossing the borders or Moores Law.
