MOTHERBOARD explains the mystery behind the radioactive hotspots.
Now, a team of researchers has presented evidence that the ancient impact ejected radioactive material, in addition to other anomalous elements, from a long-lost layer that once existed between the molten mantle of the infant Moon and its crystallizing crust, and subsequently seems to have vanished from the lunar far side.
The results “have important implications for understanding the formation and evolution of the Moon”—especially why its near and far sides are so drastically different—and suggest that samples from SPA “must be considered amongst the highest-priority targets for the advancement of planetary science,” according to a study published on Friday in the Journal of Geophysical Research: Planets.
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.
