Floral Cosmonauts is a set of self-assembling silver dendrite networks formed as part of a site-specific installation sent into space aboard Blue Origin’s New Shepard spacecraft.

Once aboard the spacecraft, the installation was controlled by a custom-programmed Raspberry Pi computer. Video artifacts of the crystal growth were recorded using Raspberry Pi-controlled cameras.

Anna Garbier was the sole coder (Python), testing & prototyping lead, and co-designer.
