Juno is an armored tank of a space mission, designed to withstand the strong radiation generated by Jupiter’s immense and powerful magnetic fields. Electrically charged ions blasted off its volcanic moon Io are swept up by Jupiter’s magnetism and accelerated to extremely high speeds until they slam into its atmosphere at the poles. Any spacecraft that gets close to Jupiter can be fried by the environment.
And Juno swings in close: its extremely elliptical orbit takes it as far out as 2.7 million kilometers, but then it dives down to just 4,000 kilometers above its cloud tops, screaming past at 200,000 kilometers per hour.
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.
