Sarah Hörst, an Assistant Prof of Planetary Science at Johns Hopkins University, recently got to hold a piece of the moon and mars in her hand and shared her excitement
Sarah also took time to answer some of the most common questions:
The black one is the Martian one, the gray one is the moon
The martian one landed on Earth after something smacked into Mars and sent rocks flying through space and all the way to Earth!
They were able to tell it was from Mars by the rock’s chemical composition and isotopes
You can read more about the Martian meteorite here
The two rocks now have their own Twitter account
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
Have an amazing project to share? The Electronics Show and Tell with Google Hangouts On-Air is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
