Scientists at the European Space Agency (ESA) have placed the same bacteria and yeasts used to make Kombucha tea on the outside of the orbiting laboratory to see how the organisms fare in the unprotected environment of space.
The Kombucha experiment is one in a series of “Expose” studies run by ESA to find out if multicellular biofilms — a community of microorganisms that can stick together on a surface — can survive in the unshielded environment above Earth’s atmosphere.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
