Once upon a time the USSR and the USA fought for dominance in space. Now countries from all over the world are headed out past the troposphere. Here’s more from the UK Science Museum:
In early 2021, three spacecraft speeding towards Mars will reach the red planet. The arrival of the United States’ Mars 2020, China’s Tianwen-1 and the United Arab Emirates’ Hope, will generate national pride and celebration in those three countries.
Just a few days before this year’s national day, the UAE’s mission executed a third and final mid-course correction. All planetary missions need these to make sure they hit their target! That Hope required only three such manoeuvres on the way to Mars – it can be far more – was itself a source of joy for the young space engineers and scientists working on their first ever interplanetary mission.

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.
