On May 5, NASA launched two, tiny, briefcase-sized satellites (called cubesats) to Mars, but at least one of them still has an eye for Earth. One of the Mars Cube One (MarCO) cubesats, nicknamed Wall-E, snapped a photo of Earth from more than half a million miles away.
Earth appears as a pale blue speck, and to its left is an even fainter speck: our moon.
NASA scientists weren’t doing this for sport, but to see if the cubesat’s antenna had unfolded — and worked.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
