If you ask Elon Musk, private space travel could be a reality in the next year, and a self-sustaining city on Mars is not far off. In the meantime, planetary scientist Kevin Cannon and his colleagues at the University of Central Florida are less concerned with the Starship that will launch passengers into orbit and more interested in how to feed a potential human settlement on Mars. In their recent paper “Feeding One Million People on Mars,” Cannon and Daniel Britt modeled a path toward self-sufficiency for one million settlers over the course of 100 Earth years—taking into account caloric intake per person, imported food in the early years, and necessary infrastructure, like pressurized food production facilities and underground tunnels for growing plants with LED lighting and sunlight piped in.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
