A systems check on the Perseverance Mars rover by NASA has left tracks on Mars. Here’s more from Astronomy Now:
During tests of the rover’s mobility system, a microphone captured the sounds of its six metal wheels crunching across the surface. This image, captured by the rover’s left-side navigation camera on 7 March, shows the robot’s tire tracks in the dusty soil of Jezero Crater. The rim of the crater is visible on the horizon, along with mesa-like remnants of an ancient river delta that may hold signs of past microbial life. NASA has posted an audio file

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.
