Using Landsat data from the US Geological survey, NASA’s Laren Dauphin recently imaged the Salar de Atacama in Chile. The enclosed basin is the world’s largest source of lithium, producing 29 percent of the world’s reserves. Much of it will wind up in rechargeable batteries used by EVs, laptops and smartphones, but how it gets there is surprising — think salt production, not pit mines.
Salar de Atacama is a salt flat from an ancient sea bed that contains massive reserves of lithium brine beneath its surface (“salar” means “salt flat”). It’s cut off in the east by the Andes mountains, and to the west by another range called Cordillera de Domeyko. It’s the driest desert in the world and with the high altitude (1.4 miles above sea level) the relentless sun would damage your skin in just minutes.

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.
