Picogram-Scale Interstellar Probes via Bioinspired Engineering
For exploring nearby stars, let us consider the challenges of a picogram- to nanogram-scale probe to land, replicate, and produce a communications module based on biominerals at the destination. A billion such probes could be launched for similar cost as a single gram-scale probe. One design is a hi...

Sumario: | For exploring nearby stars, let us consider the challenges of a picogram- to nanogram-scale probe to land, replicate, and produce a communications module based on biominerals at the destination. A billion such probes could be launched for similar cost as a single gram-scale probe. One design is a highly reflective light sail, traveling a long straight line toward the gravitational well of a destination star, and then photo-deflected to the closest nonluminous mass—ideally a planet or moon with exposed liquid water. |
