On 4 January 1986, NASA’s Voyager 2 spacecraft snapped spectacular pictures of Uranus’ moon Miranda, one of the strangest bodies in the solar system. Three lightly cratered areas of ridges and valleys, known as coronae, are separated from presumably older, heavily cratered regions, giving the surface the appearance of “mismatched patches on a moth-eaten cloth,” according to a description on NASA’s Solar System Exploration website. Giant fault canyons plunge 12 times deeper than the Grand Canyon with sheer cliffs that almost defy imagination. Thanks to the moon’s low gravity, an astronaut stepping off the edge of the highest cliff would have a full 10 minutes to reconsider the wisdom of that final step before hitting the ground below.

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.
