In this collaborative project, student teams each take on a component of the Mars Sample Return mission in order to construct and code a model of a device capable of sending Martian rocks to Earth. Groups can use multiple coding languages simultaneously to allow all levels of coders to participate. Materials Programmable microcontrollers compatible with external components, such as light sensors, LEDs, etc. (MakeON, Cubit, Micro:Bit, Raspberry Pi, etc.) Laptop or tablet (one per group) Engineer
