NASA is gearing up to test drive a submersible robot underneath Antarctica’s sea ice, with hopes of eventually sending a similar machine to search for aliens in the subsurface oceans of Jupiter’s moon Europa.
The two-wheeled robot, which is called the Buoyant Rover for Under-Ice Exploration (BRUIE), uses buoyancy to anchor itself upside-down on the bottom edge of the ice. This distinguishes it from other free-swimming robot concepts designed to look for extraterrestrial marine life, such as the EurEx (Europa Explorer).

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.
